NUMBER SYSTEM COMPUTERS CAN BE CATEGORIZED IN 2 WAYS
- is a way to represent or express numbers 1. size
- each digit have a place value, making it 2.data handling capabilities
positional value system TYPES OF COMPUTER
1. Decimal number system 1. Super Computer
2. Binary number system 2. Mainframe Computer
3. Octal number system 3. Workstation Computer
4. Hexadecimal number system 4. Personal Computer (PC)
5.. Tablets and Smartphones
DECIMAL NUMBER SYSTEM
- most common number system SUPER COMPUTER
- commonly used and basis of how we count - biggest and fastest in terms of speed
- base 10 ( 0 to 9) processing data)
BINARY NUMBER SYSTEM - designed to process huge data
- considered as computer machine language - can process trillions of data to instructions in
- utilizes two digit ( 0-1 ) just a second because of thousand
- 0 represent 'off" and 1 as "on" interconnected processor
OCTAL NUMBER SYSTEM - used in scientific and engineering
- 8 digits applications such as weather forecasting,
- base 8 (0-8) scientific simulations and nuclear energy
HEXADECIMAL NUMBER SYSTEM research
- also known as ALPHANUMERIC NUMBER CHARACTERISTIC:
SYSTEM - fastest and expensive
- uses numeric digits and alphabets - 10 trillion calculation per second
- uses numeric digits and alphabets - used in stock market or organizations
managing online currency such as bitcoin
BINARY ARITHMETIC - used in research areas fro analyzing data
- can be calculated by applying four ( exploring solar system, satellites etc.)
operations
2. MAINFRAME COMPUTERS
BINARY ADDITION - designed to support hundred-thousand of
0+0=0 users at the same time
0+1=1 - supports multiple programs
1+0=1 - ideal for banking, telecom sector
1+1=0 carry 1
BINARY SUBTRACTION MINICOMPUTER
0-0=0 - medium size of multiprocessing computer
0-1=1 - 2 or more processors that supports 4-200
1-1=0 users at the same time
0-1= 1 ( burrows 1 to have a value ) - similar to microcontroller
- used in billing, accounting , inventory
BINARY TO OTHER NUMBERS management etc. but larger compared to
process of converting binary to decimal: microcomputer
1. multiplying the bits
2. add all those products CHARACTERISTICS
- low weight, easy to carry
BINARY TO OCTAL - less expensive than mainframe
- 3 bits is equal to one octal digit - it is fast
PROCESS OF CONVERSION:
1. make pairs of 3 bits WORKSTATION COMPUTER
just add 0 on the remaining bits - designed for scientific application
2. write corresponding digits in each pair - consists microprocessor with large amount of
RAM and high graphics adapter
BINARY TO HEXADECIMAL - single-user computer
- 4 bits to equal hexadecimal digits - generally used to perform specific task with
- 0-9 is number but 10-16 is A-F great accuracy
PROCESS OF CONVERSION:
1. pair 4 bits PERSONAL COMPUTER
2. write the correspond value - also known as microcomputer
- designed for individual use
- ex. laptops and desktop computers
- is a way to represent or express numbers 1. size
