Welcome back :) Week two finaly ended. In this week we have learnt about Computer Hardware Basics. such as Computer History, Computer architecture,Size, Processing, power and Types of Computers. I ll just go through them quickly.
1st Generation-Vaccuum tube
2nd Generation-Transistors
3rd Generation-Integrated circuits (IC)
4th Generation-VLSI/ULSI
5th Generation- Nanotechnology and still going on
Computer processing power is measured in hertz (Hz). cycles per second.
1 byte= 8 bits (Binary Digits)= 1 character
The Important things about computer are as follows :
- Processor Speed
- Memory Capacity
- Hard Disc capacity
