TOPIC 1 : Knowing Computer :computer:
3) COMPONENTS OF COMPUTER SYSTEM
Central Processing Unit
microprocessor made up of millions of microscopic transistor in a circuit
process and store data using digital technology
Digital Technology
This digital concept enables the storage and processing of multimedia
Each transistor can be in either an "on" and "off " position
The "on-off" states of transistor are described using binary number system ( 1 or 0 )
Computer Memory Capacity
Exabyte (10^18 byte)
Petabyte (10^15 byte)
Terabyte (10^12 byte)
Gigabyte (10^9 byte)
Megabyte (10^6 byte)
Kilobyte (1024 bytes)
