Common Network Types

There are many different types of network

They can be used for different purposes by different types of people and organization

Here are some of the network types that you might come across:

Local Area Networks (LAN) A local area network or LAN is a network that connects computers within a limited area

This might be in a school, an office or even a home

Common Network Types

Personal Area Networks (PAN)‍ A personal area network is a network that is based on an individual's workspace

The individual's device is the center of the network, with other devices connected to it

There are also wireless personal area networks.

Home Area Networks (HAN) ‍A home area network connects devices within a home environment

It might include personal computers, tablets, smartphones, printers, TVs and other devices

Common Network Types

Wide Area Networks (WAN) ‍A wide area network is a network that covers a larger geographical area, usually with a radius of more than a kilometer

Campus Networks ‍A campus network is a LAN or set of connected LANs which is used by a government agency, university, corporation or similar organization

It is typically a network across a set of buildings that are close together

Common Network Types

Metropolitan Area Networks (MAN) ‍Metropolitan area networks are networks that stretch across a region the size of a metropolitan area

A MAN is a series of connected LANs in a city, which might also connect to a WAN

Enterprise Private Networks ‍An enterprise private network is used by a company to connect its various sites so that the different locations can share resources

Common Network Types

Internetworks ‍Internetworks connect different networks together to build a larger network

Internetworking is often used to describe building a large, global network

Backbone Networks (BBN) ‍A backbone is a part of a network that connects different pieces and provides a path for information to be exchanged.

Global Area Networks (GAN) ‍A global area network is a worldwide network that connects networks all over the globe, such as the internet

Intranets, Extranets, and Virtual Private Networks

Intranets are used within a company for data access, sharing, and collaboration

Extranets are private, company-owned networks that can be logged into remotely via the Internet

Virtual Private Networks (VPNs) are used where security of transmissions is a concern

They encrypt the packets before they are transferred over the network

Virtual Private Networks

A virtual tunnel routed through the Internet with software and hardware encryption.

Virtual Private Networks

A VPN provides the opportunity to establish a protected network connection when using public networks

VPNs encrypt your internet traffic and disguise a person’s online identity

This makes it more difficult for third parties to track activities online and steal data

The encryption takes place in real time

They essentially create a data tunnel between a local network and an exit node in another location

Which could be thousands of miles away

Making it seem as if the user is in another place

Virtual Private Networks

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol)

Network Terminology

Modem: a device that modulates/demodulates signal for transportation

Modulation and Coding: Techniques used by modem to adapt the signal to the media

Signal: Binary information we want to send.

Signal Frequency Spectrum: All the frequency components of a signal

Media Bandwidth: Limit in range of frequency signals

Capacity Bandwidth: Maximum bits per second that can be transmitted

Figure 4.4 Basic functions of business networks

Quality of Service (QoS)

Latent-sensitivity: data such as real-time voice and high-quality video.

Prioritized Traffic: data and apps that are time-delay-sensitive or latency-sensitive apps.

Throttle Traffic: gives latency-sensitive apps priority, other types of traffic need to be held back (throttled).

Traffic Shaping: the ability to prioritize and throttle network traffic.

The Net Neutrality Debate

Net neutrality is the principle that Internet Service Providers (ISPs) and their regulators treat all Internet traffic the same way.

Traffic shaping prioritizes the flow of traffic by delaying the flow of less important network traffic.

In 2010, the FCC ruled in favor of “net semi-neutrality”, not explicitly forbidding paid prioritization.

The FCC under the current administration may take further steps to roll back net neutrality rulings, which could favor the cable companies over consumers.

Network Fundamentals

Name different types of networks

Local Area Network (LAN)

Wide Area Network (WAN)

Wireless Local Area Network (WLAN)

Metropolitan Network (MAN)

Storage Area Network (SAN)

Campus Area Network/Cluster Area Network (CAN)

Personal Area Network (PAN)

Suggested Responses:

1. The different types of networks are LAN, WAN. WLAN, MAN. SAN, CAN, PAN.

2. Bandwidth is the communication capacity of a network. Bandwidth is the amount of data that passes through a network connection over time as measured in bits per second (bps). For an analogy to bandwidth, consider a pipe used to transport water. The larger the diameter of the pipe, the greater the throughput (volume) of water that flows through it and the faster water is transferred through it.

3. Intranets are used within a company for data access, sharing, and collaboration.

An extranet is a private, company-owned network that can be accessed remotely via the Internet. It connects two or more companies, suppliers, vendors, partners, or customers, so they can securely share information.

4. Virtual private networks (VPNs) encrypt the data packets before they are transferred over the network and decrypt at the receiving end.

5. A modem is a device designed to adapt/modify the information signals in a way that can be transport-ed by the media. The word modem is composed of two terms: Modulator and Demodulator, the Modulator adapts the information signal in order to be transported by the media and the Demodulator does the inverse process at reception.

6. Business networks support basic functions including: communication, mobility, collaboration, relationships, and search.

Communication: Provides sufficient capacity for human and machine generated transmissions, such as being able to talk, text, tweet, fax, send messages, etc.

Mobility: Provides secure, trusted, and reliable access from any mobile device anywhere at satisfactory download (DL) and upload (UL) speeds.

Collaboration: Supports teamwork activities that may be synchronous or asynchronous; brain storming; and knowledge and document sharing.

Relationships: Manages interaction with customers, supply chain partners, shareholders, employees, regulatory agencies, etc.

Search: Able to locate data, contracts, documents, spreadsheets, and other knowledge within an organization easily and efficiently.

7. Investments in network infrastructure, including data networks, IP addresses, routers, and switches are

business decisions because of their impact on productivity, security, user experiences, and customer service.

8. QoS technologies can be applied to create two tiers of traffic:

• Prioritize traffic: Data and apps that are time-delay-sensitive or latency-sensitive apps, such as voice and video, are given priority on the network.

• Throttle traffic: In order to give latency-sensitive apps priority, other types of traffic need to be held back (throttled).

Network Fundamentals

What is meant by “bandwidth”?

Bandwidth refers to the limitation in the range of frequency signals that can move through media without significant attenuation

The bandwidth of the media varies by type

Which is limited and typically can’t accept the entire signals frequency spectrum

The range of frequencies that can move through the media without significant attenuation is called bandwidth and it is also measured in hertz
