Consider the following in Business Information System:
-People
-Competency
- Attitude
-Critical thinking
-Best practice
1.2 Gordon Moore, co-founder of intel
Moore’s law, 1995: Computer processing power will double every eighteen
months or so. Imagine
1.3 Business Computing Hardware
Tangible and physical aspects of computing hardware
- Mainframe
- Midrange
- Microcomputer
- Laptops
- Desktops
- Handheld
System Software
Among other things system software makes hardware work. Collection of computer
programs that accomplish a specific task.
1.4 System SOftware
System software
Among other things, the system
1.6 Business Computing Software
Application SOftware
Perform particular tasks like creating a budget, resumes, or
2.1 Application Software
Performs tens of thousands of specific tasks for an end-user
- Spreadsheets
- Database
- Presentations etc.
Extremely powerful
2.2 Word Processing Software
1.1 Everything Changes
- 1903: Orville and Wilbur, Wright invent the airplane
- 1953: Watson, click, Wickens discover the double helix
- 1969: Arnsotr
1.2 Business Information Technology
- Study
- Design
- Implementation
- Support
- Management
- …..of a computer-based information system, particularly software and hardware.
- For creating documents
- Updating documents
- Editing documents
- Saved to secondary memory
Microsoft Word vs. Adobe Acrobat. Which one is better?
2.4 Database Software
- Well thought out collection of time
- Consist of records(row)
- Separated by fields
- Can be queried
- Often called a Database Management System (DBMS)
- Database software is one of the most commonly used in business,m and perhaps the
most important. A database query is only limited by imagination and the fields in the
database.
- Querying is the most important function in a DBMS
2.8 Networks
- A computer network is two or more
2,1 References and calculations
Calculations
- You can Add, Subtract, Multiply and Divide in Excel without using any built-in
functions
References
- When we perform calculations in Excel, we often reference the value stored in
other cells in our worksheet
- Re-er-ence
Relative reference
- An address or pointer that changes when the target item is moved or the
relationship has changed
Absolute References
2.2 Summary statistics Functions
Formula vs Function
- In summary, a formula is any calculation in Excel, but a function is a predefined
calculation
- Mastering the use of functions in the formula is a key in learning financial
modeling
- Formula - a manual way to make a calculation
- Function - a pre-defined calculation
Chapter Three
Knowing about the inner workings of any machine vital to critical thinking
- You may not know how it works, however it seems to work every time
- What if you have to buy or lease 200 cars for your buisnessl now is it worth to
know miles per gallon, leasing options
3.2
- The system Unit is the Main body of the computer
- The System Unit contains the Motherboard
- A variety of other assorted computer compnents
- Power supply
- Cooling fan
- Disk drivw
- The motherboard
- Sometimes called a system board ot Logic Board )apple)
- Essentially the Motherboard is a circuit board
- Printed Circuit Board
3.3
The Microprocessors
- Plugged directly inyo the motherboard
- Contained within the microprocessor is the Central processing unit
- Measured in Clock Rate
- The CPU is what a microcomputer the ability to program
Binary System
- Made up two parts
- Most microcomputers use the American standard code for Information
Interchange (ASCII)
- Convers Alternating current to Direct current
Bus line
- The pathway inside a computer is known as Bus line
- Measured in Width
- Controlled by software to connect to devices
Memory
- Two types of memory
- Primary Memory (volatile) RAM
- What the user is currently working on
- Secondary Memory - Hard drive, cloud drive, etc. ( non-volatile)
3.1 Boolean Functions
- The operator “AND” combines expressions to determine if ALL of the combine
expressions are true
4.1 Operating Systems
- B
4.2 Understanding Operating systems
- Windows is the operating software ( sometimes called platform)
4.3 Process/ Multitasking
4.6 File Manafement
4.1 Data functions
4.2 Text Function
5.3 Ones and zeros
Input devices ( like keyboards or microphones) translate what a human understands to
ones and zeros on a computer
5.4 Physical Storage Characteristicst
- Like a record player
5.6 The charting environment
Charting types
- Column Chart- A column chart is a primary chart type, with data series displayed
- Stacked Column chart- A c stacked column chart is a basic chart type to allow
comparisons over time or across categories
