The Four Generations of Computers
The First Generation of Computers
The first generation of computers were huge and created a lot of heat which was one reason for malfunction. They were very expensive and needed a lot of electricity, they solved only one problem at a time. they used vacuum tubes.
The Second Generation of Computers
The second generation of computers used transistors instead of vacuum tubes to use less space but the transistors still created heat so it damaged the computer, transistors made the computers smaller, faster and cheaper.
The Third Generation of Computers
. The third generation of computers transistors were miniaturized and placed on semiconductors; this increased the speed and efficiency of computers. It was the first computers to have keyboard and monitors and work with operating systems; it allowed the computer tun many different applications at the same time. For the first time computers were accessible to a huge amount of people because they were smaller and cheaper than their predecessors.
The Fourth Generation of Computers
The fourth generation of computers had integrated circuits onto a single silicon chip which before filled an entire room, mouses were introduced and internet was developed. Fourth generation computers became more powerful, compact, reliable, and affordable.
