Early History
In early history they find it very hard to solve the equations.
For the populations
So after they invented the calculator they invented the computer.
Which is not as fast as now but slow.
has less memory container
Very big but can contain very small information. -
Starting of the First Generation of Computers
-
Period: to
First Generation of Computers : Vacuum Tubes
In (1940 - 1956)
In that time they use vacuum tubes and magnetic drums for memory.
and very big but can store very little information.
It use a lot of heat.
Also it use a lot of electricity. -
ENIAC was annouced to the public
-
Starting of the Second Generation of Computers
The transistors came to replace the vacuum tubes.
But it is not use much that often.
It is not widespread in that time.
It was very good more than vacuum tubes.
Smaller, faster, cheaper.
It is more convenient. -

Second Generation oif Computers : Transistors
The transistors came to replace the vacuum tubes.
But it is not use much that often.
It is not widespread in that time.
It was very good more than vacuum tubes.
Smaller, faster, cheaper.
It is more convenient. -
Period: to
Thrid Generations of Computer : Integrated Circuits
Transistors become smaller.
Now it is a silicon chips.
Which is called the semiconductors.
It will increase the speed and the efficiency of the computer.
Now you can open many apps together.
They produced the keyboards and them monitor
They created the operating system. -
Starting of the third generation of computers.
-
Period: to
Fourth Generation of Computers : Microprocessors
They started building computers and improving it.
Now computers at that time looks like in the present.
Apple start producing the computers
Information are stored in these little microchips
Now it is very fast, and builded the mouse and the keyboard.
Now you can open many tabs and use many applications at the same time. -
Start of fourth generation of computers till now.
