Generations Of Computers
Generation 1 - Enormous machines which were very expensive to run. Made a lot of heat causing malfunctions. Could only solve 1 problem at a time. Used vacuum tubes.
Generation 2 - Vacuum tubes replaced by transistors. Became smaller, faster and cheaper. Moved from machine language to assembly language making them easier to program.
Generation 3 - Transistors made smaller and put onto silicon chips making computers smaller and quicker. The user could now interact through keyboard and monitor. Many applications can run at once.
Generation 4 - Thousands of circuits now built onto a chip. Built for home use. Computers were able to link to form networks which led to the intro of the internet.
