Computer History | MCQs

Explanation

Microprocessors are used in many other electronic devices, including:

• Computers,
• Digital systems,
• Calculators

Inventor of Microprocessors: Marcian E Hoff

Microprocessors in 4th generation computer.

AGM 09-2-2023

Explanation

The main electronic component used in first-generation counterparts was Vacuum Tubes and Valves.

Leo is called the first-generation computer.

The five generations of computers:

1. First Generation (1946-1959 or 1940-1956): Vacuum tube-based technology (e.g., ENIAC).
2. Second Generation (1959-1965 or 1956-1963): Transistor-based technology.
3. Third Generation (1965-1971 or 1964-1971): Integrated circuit-based technology.
4. Fourth Generation (1972-1980): VLSI microprocessor-based technology.
5. Fifth Generation (1980-present): ULSI microprocessor-based technology, with a focus on artificial intelligence.

Explanation

Derived from: computare

Means: “to calculate”, “to count”, “to sum up” or “to think together”.

Explanation

An integrated circuit is a set of electronic circuits on one small flat piece  of semiconductor material, usually silicon.

Large numbers of tiny MOSFETs  integrate into a small chip. 

First generation (1940 - 1956)  vacuum tubes as a major piece of technology.

 The ENIAC is  example of 1st generation computer.

Second generation (1956 - 1963) use of transistors.

Third generation (1964 - 1971)  use of Integrated circuits.

Fourth generation (1972 - 2010) use of the microprocessor

Fifth generation (2010 to present) use Artificial intelligence

Explanation

The ENIAC (Electronic Numerical Integrator and Computer), developed from 1943 to 1946.

It was the first general-purpose electronic digital computer.

It was designed for calculating artillery firing tables and utilized vacuum tubes.

Explanation

English mathematician and inventor Charles Babbage is often called the father of computers.

Because he introduced the basic ideas that nearly all modern computers rely on.

Babbage started designing an analytical engine in 1830, which could be programmed to perform calculations using punched cards.

Explanation

John Bardeen, William B. Shockley, and Walter H. Brattain are collectively known as the fathers of the second generation of computers.

They invented the transistor in 1947, which led to the development of smaller, faster, and more efficient computers.

The fathers of each generation of computers:

1. First generation (Vacuum Tubes): John Atanasoff (invented the first electronic computer, ABC)
2. Second generation (Transistors): John Bardeen, William B. Shockley, and Walter H. Brattain (invented the transistor)
3. Third generation (Integrated Circuits): Jack Kilby (developed the first integrated circuit)
4. Fourth generation (Microprocessors): Ted Hoff and Stanley Mazor (developed the first microprocessor, Intel 4004)

Explanation

IBM stands for International business machines.

IBM 1401 belong to second generation. 

Second generation of computer: 1956 to 1963

Used in Second Generation: Transistors
