As I am not fully familiar with the different types of topologies in regards to
networks I will say that when it comes to the basics such as logical and physical I
am used to both. An this comes from personal experience in dealing with them
both. Not only from several set ups I've done but also have worked on. Via Wi-Fi
and actual computer set ups. This has taught me that both have there strengths and
weaknesses respectively. For example the physical topology comes in handy when
you want to run a close knit network that stays within a controlled environment but
has limited connectivity. Not a problem if you want to do limited activity and not
connect to a larger network e.g logical. this particular network is far more versatile
and widespread than just a simple use of the physical. Now if you where to
combine the two then you may be able to counter act the weaknesses of each other
while at the same time combining there strengths. Such as putting the protection of
a physical network and expanding its very limited range while helping with the lack
of security that a logical topology has. The term "network topology" refers to the
arrangement of the elements found in a network. You may have a network topology
at home and/or at work. The first one that I would like to discuss is the star
topology. This is the type that I use for my home internet. I have a central hub that
is my router/modem. From there, I have ethernet connected to my Xbox and PC.
My wireless devices is connected via a this central hub. The strength of this type of
network is the simplicity. You can just add another line or or device directly to the
central hub. The disadvantage of this type of network is that if the central hub gets
damaged, your whole network is down.The next type of network topology I'd like to
discuss is hybrid. It's probably the most versatile topology and there are very few
limitations to this network setup. Hybrid network is a combination of more than 1
types of topology. When I worked in a call center, this is the type of network we
used. The disadvantage of this network is the complexity of it. I think the network
topology I'm most familiar with on a commercial level would have to be the star
topology. I've seen it a lot in some call centers that I've worked at where several
computers are connected to a main hub. One of the biggest advantages to the star
topology is that it's quick and easy to add new computers and it's easy to identify
the computer with issues. If a cable goes out, the whole system doesn't collapse.
Though the reading activity described a disadvantage being that there are two points
of failure, I still feel like that's just another advantage of it. Having two points of
failure lessens the time it would take to troubleshoot the issue.Alternatively, I am
also familiar with point to point topology, which is where you have a direct
communication path. For example, my gaming computer is directly connected to an
ethernet switch, and given how little I know about networking, I feel like that's like
a point-to-point topology. I feel like the advantages to this topology is that it's
simple to set up, but a big disadvantage is that it's not really feasible in large scale
corporations. Network topology is the arrangement of the elements of a
communication network. Network topology can be used to define or describe the
arrangement of various types of telecommunication networks, ... signal types may
differ between two different networks, yet their logical topologies may be identical.
One of the different networks is Star Topology. In star topology, all the devices are
connected to a single hub through a cable. This hub is the central node and all
others nodes are connected to the central node. The hub can be passive in nature
not intelligent hub such as broadcasting devices, at the same time the hub can be
intelligent known as active ?hubs. Active hubs have repeaters in them. Mesh
Topology :
In mesh topology, every device is connected to another device via particular channel.
Every device is connected with another via dedicated channels. Most mesh networks
have a self-healing capability as data can be re-routed using another path if one
repeater node fails, thereby enhancing robustness.Thanks to one-hop, point-to-point
connection, star topology is much simpler and less expensive to implement compared
to mesh topology. Network security also increases, as endpoints operate independently
of each other; if a node is attacked, the rest of your network still remains intact.
The two network topologies that I am most interest in are the Ring Topology and
Star Topology. With the Ring Topology there are two dedicated point to point links
a device has with the devices on the either side of it. When a device wants to send
data to another device then it sends the data in one direction. if the received data is
intended for other device then repeater forwards this data until the intended device
receives it. Ring Topology strengths start with a easy install, along with managing to
add or remove a device from the topology there are only two links required to be
changed. Ring Topology weakness starts with data traffic issues because all the data
is circulating in a ring. If there is a link failure the entire network as the signal will
not travel forward. Now with the Star Topology each device in the network is
connected to a central device called hub. It doesn’t allow direct communication
between devices; the device must communicate through hub. Data is sent to the hub
and then the hub transmit that data to the designated device. A strength in the Star
Topology is the easy fault detection because the link can be easily identified. There
are not many cables required because each device needs to be connected with the
hub only. A weakness with the Star Topology is if the hub goes down everything
goes down, none of the devices will work without a hub. When I had first opened
this weeks discussion I immediately put my head in my hands, I had no idea what
the discussion topic was referring to. Thankfully, I now understand.
Networking technologies are all around us everyday, and we don't even realize it.
The two technologies I'd like to talk about are Bluetooth and Ethernet.
Starting with the latter, ethernet, is a bounded networking technology we use almost
on a daily basis. I know personally my PC is hardwired. Some people may think,
why wired if you can use the wifi and go unbound? With this ethernet connection I
am getting a way faster data transfer rate and overall a much better performance out
of my internet.
Second, let's talk about bluetooth. Now, if you guys are 90's babies like me, you'll
remember when bluetooth first flooded the market. You couldn't walk into a
electronics store with out hearing about a bluetooth headset. As it turns out,
bluetooth is NOT the brand name of this wireless headset. My mind was blown.
Bluetooth is it's own type of networking technology. Bluetooth is an unbounded
personal area network or PAN for short. It is a short range wireless connection
letting us connect devices together, such as your watch to your phone or your phone
to your bluetooth speaker. It is very similar to wifi, but the range is much shorter. I
am very familiar with local area networks I get a bit lost when it comes to larger
networks such as the ones at my job for example. A small network like I have at
home is simple enough to understand as I have a modem which brings the internet
from the ISP and the router is what gives off the signal for wifi. From there I have
1 pc and a laptop that share a printer. At work however there are hundreds of
devices on the LWAP throughtout the warehouse. All of the employee devices are
automatically configured when they connect to the access point. That is where I get
lost. different types of topologies that I am most familiar with are Point to Point
and Bus. Point to Point because that is what I use here at home especially during
the cOVID time. Bus topology I have also used when i had a logistic company and
it was very easy to setup and worked perfectly for the 6 people that worked in the
office. The strengthens for point to point is sharing all info from on computer to the
other but is only good for two users. Bus topology is cost effective and can connect
all devices to the network with a signal ethernet cable and you can easily add and
remove devices from the network. The disadvantages of the bus is that if the
network cables goes down then the entire network goes down and can sometimes
hard to identify and causes the work stoppages. I absolutely love setting up networks
using hubs and setting up whole homes wireless connections which is why i picked
this field to major in. Well, I'm not that familiar with the different types of
networks out there. I have used what they called a peer - to - peer network for a
small construction company. Mainly 4 computers set up in an office that could share
information between all machines. I think this is also called a point - to - point
network from the search on different topologies out there. I have also worked with a
WAN (Wide Area Network) for a major store system worldwide. The best
description on the topologies would be a tree topology. Each store would have it's
own network and then link back to the home office to share daily sales, order info,
stock requests etc. The downside to Peer-to-Peer is that when someone updates from
a remote location, then the others must wait until the remote terminal is reconnected
to get those updates or they would be using incorrect data. However the benefits of
the tree topology would also be if a store went down for any reason then the
remaining stores would be able to continue operations without impact. There are 5
different types of topology these would include mash, star, bus, ring , and hybrid. 2
types I am most familiar with would be mesh and star topology. Mesh topology is
secure an unauthorized access is not possible. There's a dedicated link with 2 devices
that link is only available between those 2 and there are no data traffic issues. Also
detection of faults is easier. The difference between star topology to mesh is that it
does not allow a connection between devices it is connected do a central hub
device. Connections between star topology if another device needs to be connected
sends data straight to the hub then transmits to the device in question. Because this
works with one port and connected directly to the hub this link is less expensive
and easier to install. Having one straight connection to the hub for these devices less
cords and cables are needed and if one link fails another connection will pick up.
Fault detection can be easier to be identified because of their Drake connection to
the central hub and not going through one transmitted device connection or link. I
will start by saying when it comes to this class i am a complete novice. Given
those facts I will do my best to keep up with the proper terms and I am always
willing to learn from those with more experience than me in this subject. I found
out that there are five different types of network topologies. The two I choose was
Star and Bus topology. They are constructed in a model that was similar to that of
the fire department.
Star Topology is when each device in the network is connected to a central device
called a hub. There are always advantages and disadvantages with each different
topology. An advantage of the Star network is it is the less expensive because each
device only needs one I/O port and only needs to be connected to the hub with one
link. A second advantage is its the easiest to install, it has the least amount of
cables because each device needs to be connected to the hub.
The second network I choose was the Bus Topology, In the bus topology there is a
main cable and all the devices are connected to this main cable through drop lines.
There is a device called a Tap that connects the drop line to the main cables. Since
all the data is transmitted over the main cable there is a limit of drop lines and the
distance a main cable can have. One advantage of the Bus topology it has very easy
installation, each cable needs to be connected with backbone cables. Another
advantage is that it requires very little cable unlike the star and mesh topology. The
disadvantages of the Bus topology is it has difficult in fault detection. Its not
scalable as there is a limit of how many nodes you can connect with backbone
cable. One network topology I am familiar with is the star topology. When I have
worked with this topology it was fairly simple to work with because everything is
connected to a central point. Since everything is connected individually to the central
hub if something goes wrong with part of the network it is easier to troubleshoot
then some of the networks that are all connected in a sequence. When you are
wanting to add or move a station to your network it is easier to do with the star
topology since all that has to be done is to add or remove a new cable to the hub.
Some disadvantages to the star topology is that with the amount of cable needed it
can be costly, and the whole system can go down if the central hub fails since
everything is running off of the one point.
With some smaller companies I have worked with they use the bus topology. It is
easy to install and since everything is hooked up to one main cable it is doesn't
cost a lot. The worst part I would say about the bus topology is that if something
goes wrong within the network it can be hard to figure out where the problem is.
There are two different types of network topographies and technologies that exist and
are utilized are wired and wireless networks. I am very familiar with both types of
networks as I have used them both. Wired networks definitely have their advantages
and disadvantages. Wired networks are known for being reliable since they are
hooked directly into a router or server. This is an advantage because there is no
signal loss and no interference. The main disadvantage, however, is the very wire
itself. Because it is directly connected, the problem becomes that if the wire is
severed along the way, the connection is instantly terminated. A wireless connection
gives the user the freedom to set up their network wherever and however they so
choose. It does not need to be situated in a certain place because of a wire needing
to be connected. As I mentioned before, the disadvantage to a wireless network is
that it is susceptible to outside interference such as radio waves or even at times a
Bluetooth signal can reek havoc. Without knowing much about the terminology of
networking devices, I have used a few of the components listed in this week’s
lesson. Workstations, servers and host are the most common ones that I have
encountered. Working as an Army instructor in Virginia, we had our own
workstations and we even had server room duty. Server room duty was a fabricated
task to ensure that the server room was clean and we had to ensure that the servers
did not overheat due to teaching in an older building with poor air circulation.
When I moved to Virginia several years back, I purchased cable television and my
internet service provider was through Verizon. I had no idea what Fios was at the
time. I was informed by a few friends that it pretty much meant my internet service
and speed was going to be top notch. After this week’s readings, I’m a bit more
enlightened on what I actually had. I know that I had the straight tip (st) connector
and after my service was initially installed, I snapped several pictures of the back of
my router, cable box, and television so I could know how the cables and connectors
were configured. The ST fiber-optic connector (developed by AT&T) is one of the
most widely used fiber-optic connectors; it uses a BNC attachment mechanism
similar to Thinnet's that makes connections and disconnections fairly frustration-free .
I did not have any issues reconnecting my cables when I decided to move my
furniture around. I am choosing to discuss two topologies that I have some
experience with, although at the time I did not know what a topology was.
First is the Bus topology, which is pretty simple and straight forward. You begin at
one end of the line and stretch it to as many locations as needed. You will
terminate the line at each end. As the lesson explained there is very little fault
tolerance with these and current data can only be ran on one workstation at a time.
When I was in the Navy I worked with one of these on the ship, it was a Unix
based testing system that contained a total of 7 stations, 2 of which were a primary
and backup server. We found out the hard way that you cannot have both servers
actively running at the same time. Also, with the bus extending beyond the servers
on each end of the network, if that server was down there was not communication
with the stations beyond them either. In my current line of work we connect
printers(Coding machines) to a central switch or hub in order to use label creating
software in a group of machines. This software can be used with multiple different
types of equipment at the same time but the equipment only talks primarily with a
central unit connected to the hub. This is a Star topology, which has better fault
tolerance and communication but if the central hub/switch goes down everything is
down. These are fairly easy to troubleshoot, typically the hub or a line between the
equipment and hub has gone bad. Wired is secure, reliable, resistant to interference,
and maintains higher throughput speeds instead of having fluctuations caused by
signal strength and physical objects blocking signal.Wireless is convenient, easier to
set up, cheaper to set up, and doesn't need extra hardware for every single device
connected to it.I love wired networks so much more than wireless. It's plug and play
for me, and it works so much more reliably than wireless does. I have several
devices connected via wired lines because they need stability and they're not going
to be jumping around from room to room. I always enjoyed running my own cables,
terminating the ends, installing wall outlets, fishing cables through the walls, and all
of the really hands-on stuff you get with a physical network. Wireless has always
been a headache for me, with interference, unauthorized devices trying to connect,
devices deciding they no longer want to work in the exact same configuration
they've been in for months, and devices unable to share the same encryption
standards due to legacy requirements. Right now I have four devices that simply
wont work on the wireless network I have because there's something up with the
2.4ghz band on the router, so whenever I want to use those devices I have to use a
passthrough wireless access point like a phone tethered via USB acting as the
wireless card. I don't have issues like this using wired connections. The two network
topologies I am used to are Bus & Tree Topology. I know that Bus topology is to
keep the layout simple, and that it only requires one cable to be connected. Tree
topology is used to extend bus and star topologies. The most significant weakness of
tree topology is the root node. However, relying on one cable does mean that bus
topologies have a single point of failure. If the cable fails then the entire network
will go down. A cable failure would cost organizations a lot of time while they
attempt to resume service. One type of network topology is the star topology. In my
opinion, star topology is the most common type in today’s world. It consists of
multiple computers or devices connected to a central point with cables or via
wireless connection. I’ll use my home set up as an example. I have a wireless
router, which can act as a switch because it has multiple open ports in the back,
with many different devices connected via wireless connection (most of the time).
The devices we have at home that utilize the wireless connection is 2 laptops, a
desktop, an iPad, and a Playstation 4. One strength is convenience. All devices can
connect to the Internet at the same time. If my router is in the living room and I
use my laptop in the bedroom, I can remain connected (depending on the signal
strength). Another strength is if one device fails, the rest wouldn’t be affected.
However, if the central point fails, then your devices won’t be able to connect to
the Internet. Also, the more devices that are connected at the same time, the slower
the Internet speed. You just have to make sure to choose the best router that can
handle multiple devices at the same time and one that will last you a long time,
which means you may need to spend some money on a good one. Another type of
network topology is ring topology. This one is more outdated. The term describes
itself. It’s essentially multiple computers directly connected to one another within the
same network. I personally don’t think there’s any advantage in having this type of
topology. One major weakness is that if one computer crashes, the network is
affected. Even if one cable is faulty and no longer works, then the network is
affected. Each computer relies on one another .I’m most familiar with star topology
because I have this set up at home and at my job. The first network that I am
going to describe is the Star Topology. This topology is named "Star Topology"
because of it's general star shape. Each point of the star represents a different
element that is connected to a central device in the middle of the star (i.e
hub/switch?). Each computer/element that is connected can be potentially controlled
by this central device. This central hub also works as a repeater for data flow. One
advantage of this topology is the simple fact that all devices can be accessed by one
central unit.A disadvantage might be that if the main/central switch has any type of
failure, then all things connected to it will also be out of commission. The next type
of network topology that I would like to discuss is the Bus Toplogy. This type of
topology is defined by the use of a main cable which has terminators on both ends.
All the other nodes like workstations, peripherals, etc. are connected to the main
cable. One advantage of Bus Topology is that it ha s a simple, easy to use, layout.
This can be handy and preferred for a small network that doesn't expect any
immediate growth. This would also be one of the disadvantages in the sense of
company expansion. I do not have a lot of personal experience with these network
types other than at my high school and my public library. My high school was
small and I am pretty sure that they used a Bus Typology. It only had 2 rows of
computers and everything was connected by cables. But, that was a long time ago
and I would imagine that this school has since upgraded to possibly a Star Topology
layout. The two network topologies that I am the most familiar with are the star and
point-to-point. Star topology is what comes to mind when I think of a network.
Several hosts connected to a central device that allows them all to communicate. The
biggest strength being that if one connection goes down, the other devices can still
function without it. Although, if the central device fails it could take the network
down. The other network topology I’m familiar with is point-to-point. In its most
basic form, it’s two devices connected to each other either wired or wirelessly.
Computers can transfer files or the way I can think of using it is with video games.
I used to play the Pokémon series on my Gameboy Advance SP and one of the
things you could do was connect two Gameboys with a link cable to trade or battle.
The newer generations can do it wirelessly now but back then, you had to hope the
cable was good or you couldn’t do it. It was easy to set up though since you just
need to plug one cable to both devices. Two name two different topologies one of
them is a star topology which is where computers are connected to a central point
with their own individual cables or wireless connections. You'll mostly see this being
used with devices such as a hub, a switch, or an access point. One of the main
features that each computer or network segments is connected to the central device
individually. So if one cable fails it will only bring down the one that its connected
to and want have any effect on the other computer. A star topology is also easy to
troubleshoot if there is any issues. Now the cost of the installation is going to be
higher because of the number of cables that are going to be used. Secondly, you
have a point-to-point topology is when a serial able is linked to a physical network,
or if they're located far apart and connected only via a circuit with a Frame Relay
or MPLS network, it's a logical network instead. You'll see this being used in a
WAN connection when a computer is connected to a hub or switch. The two
network topologies I going to go over are the bus topologies and star topologies.
With a bus topologies there is one ingle cable that will run the Length of the
network all the computers will connect into that one length of network cable if there
is a break in that network cable then all although computers will go down there is
required less cable for setting up a bus topology with only one cable it is harder to
find out where the network when down at. The cost is low because there is less
cable that you have to use. Terminators are required at both ends of the cable. A
bus topology is not mean to be used as a standalone in a large building.
Star topologies has a switch or hub in the center of the network. The big
advantages to a start is that there easy to install and wire. If there is a disruption to
one of the computer in the network the rest of them will still work. With a star
topology there is more cable that it need to set witch can be a Disadvantage
because it will take more time to set up. if the hub or the switch goes down the
whole network goes down but it is easy to find the faults in the network. The type
of network that I have the most experience with would be a LAN network. This is
the only type of network that I have set up once I have had the internet hooked up
at my house. I have set up different laptops, media devices (Roku, amazon fire
stick, and cell phones), and my Xbox. My network has both wired and wireless
devices set up now. The topologies that I am utilizing would be Star and wired. I
would say that my weakness with my network right now my security since I am
still using the modem from my internet service provider. Networking is a lot more
complicated than I thought it would be coming into this class. I understand the point-
to-point, star, and the mesh topologies in a physical sense. But I think my greatest
weakness coming into networking will be the different network types and topologies
in the logical sense. I would like to say I see things logically but that is mostly
when it comes to how physical objects operate or are assembled. A bus topology is
a topology for a Local Area Network (LAN) in which all the nodes are connected
to a single cable. The cable to which the nodes connect is called a "backbone". If
the backbone is broken, the entire segment fails. Bus topologies are relatively easy
to install and don't require much cabling compared to the alternatives. Bus topologies
were often used in smaller networks. One of the main reasons is that they keep the
layout simple. All devices are connected to a single cable so you don’t need to
manage a complex topological setup. The layout also helped make bus topologies
cost-effective because they can be run with a single cable. In the event that more
devices need to be added then you could simply join your cable to another cable.
However, relying on one cable does mean that bus topologies have a single point of
failure. If the cable fails then the entire network will go down. A cable failure
would cost organizations a lot of time while they attempt to resume service. Further
to this, high network traffic would decrease network performance because all the
data travels through one cable. A ring topology is a network configuration where
device connections create a circular data path. Each networked device is connected to
two others, like points on a circle. Together, devices in a ring topology are referred
to as a ring network. Ring Topology Easy to manage and with a low risk of
collision but reliant on all nodes being powered up and in full working order. Rarely
used today. Okay so from my limited knowledge of the subject and what I could
find for a little research is basically there are two types of network topologies.
Physical topology and Logical topology. So my understanding is Physical refers more
to the actual linking of nodes and locations. This is called cabling and basically
determines the capabilities of the network. The Logical topology is more on the
wireless data side. It has to do with how the information travels through the network
without needing the actual physical connections. So my taking of this is basically
just that one deals with physical connections and the other is basically wireless data
flow between nodes. The one i would say I feel most familiar with is the Star
topology. It seems like that is the basic one for all types of networking. From uses
in schools to companies. I chose these two topologies know as a bus and a star.
Since I'm the most familiar with these types of topologies because they're most
common with LAN in offices and schools.
A bus is when the lines are connected together on a single cabled network. The
flow of the network goes in one direction. The reason that its called a bus is
because if it crash in one stop the whole system fails. Sort of like a bus on road in
an accident blocking traffic. The only good thing about a bus topology is that its
very inexpensive that is why most companies still use this today even thought its
the most prone to crash.
A star topology is when a computer is connect to its own cable to either a router
or switch to connect to a network. In short this make the network system look like
a star. A star is actually the easiest to troubleshoot. A star is also better when it
comes to installing a new computer or replacing a old one from the network.
However, most companies shy away from this topology because its very expensive
that's really the only downside to a star.
I'm the most familiar with a bus topology since that seems to be the one that my
office uses and its not the greatest either if something happens we all can't work if
the connection fails. Then we must try and figure out and troubleshoot where the
connection is failing. Topologies for a network is like a road map and depending on
how you need to use your network or how fast you need it will depend on how the
network is setup. Like if you were driving, do you need to go around traffic or
even have faster speeds to gain more ground. Different network setups have
advantages and disadvantages. Like the bus topology this is a cost effective way to
setup a network using one line but the downside is if something were to happen to
the cable it would take down the whole network, it also isn’t setup for large
amounts of data transmission so this limits the size of a network. Mesh topology is
a resilient system that has less likely to have failures. The bad part of using a mesh
topology is that it is labor intensive to setup and can cost more due to needing
more cabling. I think in the long run the mesh would be a nice choice to go with
and offers less chance of downtime that could ruin productivity. Some Network
Topology types that i am familiar with is Point to Point and Tree. In my experience
a point to point topology is used to allow two systems to communicate between
each other. This often requires them to be on the same network for file sharing but
can also pertain to a remote access for one system as long as all TCP ports are
open. for example to use RDP the listening computer should have port 3389 open
for the other system to access this computer. Another Topology i am somewhat
familiar with is a tree topology. This network is passed in a line to switches and
these switches are distributing internet to a selected number of computers on this
network. For instance a building could have 9 computers and three switches and 3
computers are connected to each switch. This provides reliable connectivity and
repair service turn around since if multiple systems encounter connection issues its
likely a result of the switch rather than a bus where each computer is directly
connected to the server. I'm sure that some of the correct terms are not being used
correctly but in theory a tree topology provides some sort of connectivity fault
tolerance than a bus connection type. there are a total of 5 types of network
topologies. The two I’m going to be discussing are the mesh topology and the bus
topology. I’m not too familiar with any of the two, but after this course I definitely
will be. Both of these topologies have their weaknesses and strengths. For the mesh
topology if I put it into my own words every device is connected to the each other
on the same channel. The strengths about this topology is that it is robust and any
errors are resolved quickly. Also provide great security and privacy. The cost of
keeping this network up to par is costly and the installation can be difficult. The
bus network has every device or computer connected to a single cable and it only
transmits data in one direction from on end to another. One advantage of this
topology is that the wiring for installation is less costly. One thing I found would
be a headache with this network is if that one common cable failed the whole
system would crash. So after doing a lil research on the names of the topologies the
one i feel most familiar with is the Star topology. It uses 1 connection to reach all
the computers on the network. This is really common with home networks and small
business networks. The strength for this one seems to be that if one computer goes
down the rest should still work, It is cheaper to maintain, easier to set up. The
weakness's are big to though because if the router/network goes down they are all
down. The second network i have experience with is the Bus Topology. This felt
very common in high school classrooms with desktop computers lining them up to
each have their own rows tied to one network/router each per row. The strengths
here lie with the ability to continue working in other rows if one line goes down,
The cost is still fairly priced to maintain, and the set is up just repetitive but still
easy. weakness here will lie on having more effort to patch into each network if
issues arise.
