-
Period: to
1st Generation
CHARACTERISTICS
- They were very large and expensive
- They used lots of electricity
ELECTRICAL COMPONENTS
Vacuum tubes
- They were glass bulbs with wires to carry data via electronic signaling
- They were very large and inefficient
- They had no Operating System -
The ENIAC
It was the fist computer, built in 1945 -
Period: to
2nd Generation
CHARACTERISTICS
- They were smaller, faster and cheaper than the previous generation
ELECTRICAL COMPONENTS
transistors
- They produced less heat and needed less maintenance
magnetic core
- They made the memory faster and more reliable -
IBM 7070 computer
-
Period: to
3rd Generation
CHARACTERISTICS
- They were smaller, more reliable, faster and cheaper than the previous generation
- They used less electricity, generated less heat and needed less maintenance needed
ELECTRICAL COMPONENTS
Integrated Circuits (IC)
- They were the same size as transistors but 1000 times as fast -
UNIVAC computer
-
Period: to
4th Generation
CHARACTERISTICS
These computers were smaller, chaper, faster and more portable than the previous generation computers. They also used less electricity.
They incorporated new technologies such as the mouse, the RAM, the hard drive, the internet, WiFi and Bluetooth.
ELECTRICAL COMPONENTS
Microprocessors
They were silicon chips with thousands of circuits -
MACintosh computer
-
Period: to
5th Generation
CHARACTERISTICS
These are the fastest and most advanced kind of computer we know. They come with Artificial Intelligence or AI.
Some of them use Quantum technology to process information lots faster.
ELECTRICAL COMPONENTS
They use MICROPROCESSORS, just as the 4thh generation computers. -
AI based computer
