The Five Generations Of Computers
Five Different Models
In the past and present we have developed five generations of computer. Each of the five generations are categorized by the major change that differentiated the way computers work. The history of computers is often referred to the different generations of computer. Each of the generations have a different monumental technical development, resulting in smaller and cheaper PCs.
1940 - 1956, this first generation was vacuum based. These computers were often enormous and took up whole rooms. They were very expensive and used up a lot of electricity to run them. They also generated loads of heat which was the source of most malfunctions. First Generation computers often relied on machine language, the lowest language programming that's understood by computers and they could only perform one task at a time.
1956 - 1963, the second generation replaced vacuum tubes with transistors. Transistors were invented in 1947 but was not widely used in computers till the late 1950s. They allowed computers to become smaller, faster, cheaper, more energy efficient and more reliable than the first generation computers before them.
Present - beyond, this generation of computer is now based on artificial intelligence with some applications, such as voice recognition, being used today. The goal of fifth generation computers is to develop devices that respond to natural language and are capable of learning and self organization.
