What technologies were used on the 1st 2nd and 3rd generation of computers?

The five generations of computers

• 1940 – 1956: First Generation – Vacuum Tubes. These early computers used vacuum tubes as circuitry and magnetic drums for memory.
• 1956 – 1963: Second Generation – Transistors.
• 1964 – 1971: Third Generation – Integrated Circuits.
• 1972 – 2010: Fourth Generation – Microprocessors.

What device is used in first generation of computer?

vacuum tubes
A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. Although superseded by second-generation, transistorized computers, vacuum-tube computers continued to be built into the 1960s.

What device was used in the third generation of computer?

Integrated Circuits
The computers of third generation used Integrated Circuits (ICs) in place of transistors. A single IC has many transistors, resistors, and capacitors along with the associated circuitry. The IC was invented by Jack Kilby.

Which was the technology used in the first second third fourth and fifth generation computers?

The term “fifth generation” was intended to convey the system as being advanced. In the history of computing hardware, computers using vacuum tubes were called the first generation; transistors and diodes, the second; integrated circuits, the third; and those using microprocessors, the fourth.

Which device is used in 2nd generation computer?

transistor computer
A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes.

What are the examples of second generation computers?

Examples of the second generation computers include IBM 1620, IBM 7094, CDC 1604, CDC 3600, UNIVAC 1108. As a result, they worked on AC and therefore were faster than their predecessors.

What are the examples of third generation computers?

Examples of the third generation computers include IBM-360 series, Honeywell-6000 series, PDP (Personal Data Processor), and IBM-370/168.

What was the main technology used in fourth generation computers?

VLSI
Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation.

Which electronic components are used in second generation computers?

A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable.
