Answer: (e)

Computers have four basic functions: 

1. They take in raw data (input)

2 They store data (storage)

3 They manipulate data (processing)

4. They provide the user with information (output).

Answer: (e)

A notebook computer is a personal computer designed to be easily portable and capable of being run on batteries and electrical current if needed.

Answer: (d)

The standard punched card, originally invented by Herman Hollerith, was first used for vital statistics tabulation by the New York City Board of Health and several states. After this trial use, punched cards were adopted for use in the 1890 census.

Answer: (b)

A personal computer (PC) may also refer to any small, relatively inexpensive computer designed for an individual user

Answer: (b)

A supercomputer is a computer that performs at a high level than a general-purpose computer.

Instead of million instructions per second, the performance of a supercomputer is often measured in floating-point operations per second (FLOPS) (MIPS).

All the world's fastest 500 supercomputers have been running Linux-based operating systems since November 2017.

In the United States, the European Union, Taiwan, Japan, and China, more research is being done to develop faster, more powerful, and technologically better exascale supercomputers.

Quantum mechanics, weather forecasting, climate research, oil and gas exploration, molecular modelling (computing the structures and properties of chemical compounds, biological macromolecules, polymers, and crystals), and physics are just a few of the computationally intensive tasks that supercomputers are used for (such as simulations of the early moments of the universe, aeroplane and spacecraft aerodynamics, the detonation of nuclear weapons, and nuclear fusion).
