-
It is a storage data.
-
In 1945, we started having a memory to hold like the data. It is called "Vacuum tubes" and "magnetic drums". It is non portable because the big size.
-
It was first announced. It is the first electronic general purpose computer.
-
Comes from the word UNIVersal Automatic Computers.
-
It contains a number of transistor.
-
They used transistors and memory. Transistors took place of the vacuum tubes. The assembly language was even easier than binary codes. It also has printers. Because of a very hot heat of the computer workig hard, they also needed air condition to keep he computer cooled down.
-
It is a semiconductor that switch from electric to power.
-
The controller "mouse" was invented
-
The transistor is smaller and is placed on the silion chips. It could run different kinds of Applications. They also used Semiconductor.
-
This is one of the modern computers. It can be used to play games and do many other applications. Million of components are in the silicon chips. It is connected to the world by internet and world wide web. It is from 1971 to the present.
-
Mouse was not popular when it first made. It began to became populer when apple also made one.
-
An apple product had released Macintosh in 1984. I think it is one of the 4th generation computers.
-
The Apple portable macintosh is released. In nowaday it's like Macbook.
-
World Wide Wed is published.
-
Four people got the Noble award for Physics in 2000. Which were Kilby, Lehovec, Noyce and Hoerni.
-
It was launched by Apple.
