Computer Technology | MCQs

Explanation

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.

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

Artificial intelligence is intelligence demonstrated by machines, as opposed to the natural intelligence displayed by humans or animals.

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

A microprocessor is a computer processor wherein the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits.

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

Modern computers often work on hybrid technology.

This term refers to combining different technologies to improve functionality, efficiency, and versatility.

Explanation

Technology is the application of knowledge for achieving practical goals in a reproducible way.

Computer Technology and Disadvantages

Computer technology has changed the world and made life easier in many ways. It helps in education, communication, business, and entertainment. However, it also has some disadvantages. Too much use of computers can affect our health, such as causing eye strain and poor posture. People may also become addicted to games or social media, which wastes time. Cyberbullying, online scams, and data theft are other serious problems. While computer technology is useful, we must use it wisely and carefully.
