The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
Second Generation (1956-1963) TransistorsTransistorsreplaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.
Third Generation (1964-1971) Integrated CircuitsThe development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on siliconchips, called semiconductors, which drastically increased the speed and efficiency of computers.
Fourth Generation (1971-Present) MicroprocessorsThe microprocessorbrought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer-from the central processing unit and memory to input/output controls-on a single chip.
Fifth Generation (Present and Beyond) Artificial IntelligenceFifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make Artificial Intelligence a reality. Quantum computation and molecular andnanotechnologywill radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.
What else can I help you with?
Are Computers that used transistors are referred to as third-generation computers?
no, second generation. third generation computers used ICs.
What are the storage capacity of 1st to 5th generation computers?
it varied significantly from computer to computer within each generation with large overlaps from generation to generation but the running trend has been for greater storage capacity in each successive generation.
Why are the fourth generation computers called digital computers?
Because the first, second, and third generation computers were also digital computers.
History of computer Before 1st generation of computers?
Electro-Mechanical Computers were used before first generation of computers.
What are the differences between fourth and fifth generation of computer?
4th generation of computers are acts as user define computers but 5th generation computers are act as automatic computers by means it doing its works automatically
Which generation most of the computers available today are?
5th generation
What is the chip that powers the 4th and 5th generation of computers?
it know as the silicon chip
What are zero generation computers?
zero generation computers are mainly those computers that are mechanical. one example is the abacus.
Are Computers that used transistors are referred to as third-generation computers?
no, second generation. third generation computers used ICs.
First generation computers are called ICL2900HP9845 A VAX11780.What are second generation computers called?
Second Generation computers. The VAX mentioned above is just a single model of first generation electronic computers.
What are features for second generation computer?
Second generation computers are often called transistorized computers. The transistorized computers are more advanced computers than the first generation of computers.
