Explanation

The atomic mass (also known as atomic weight) of an element is the total mass of protons and neutrons present in the nucleus of an atom.

This includes:

• Mass of protons (which defines the element)
• Mass of neutrons (which varies in different isotopes)

Explanation

All the isotopes of the same element have the same number of protons, which defines the element.

Different isotopes can exist depending on the neutron count.

Electrons are negatively charged and can counterbalance the positive charge of protons.

Also, they are present in equal numbers in neutral atoms of the same element.

Explanation

• JPEG (Joint Photographic Experts Group) is a file format used for images, not text documents.
• It's commonly used for photos and graphics.

The file extensions suitable for MS Word files:

• .doc: An older file format used by MS Word (up to version 2003).
• .rtf: Rich Text Format, a file format that can be opened by MS Word and other word processing software.
• .docx: The current file format used by MS Word (version 2007 and later).

Explanation

An algorithm is a sequence of instructions in a computer language that is designed to solve a specific problem or achieve a particular goal.

It's a step-by-step procedure to get the desired results.

Explanation

• A LAN is a computer network that connects devices in a limited geographical area, such as an office building, campus, or home.
• It's perfect for connecting different computers in an organized manner within an office building.

Note:

• MAN (Metropolitan Area Network): Covers a larger area, like a city or town.
• WAN (Wide Area Network): Covers a vast geographical area, like a country or continent.

Explanation

Tally is an accounting software, which is an application software, not a system software.

System software includes:

• Assembler: Translates assembly language into machine code.
• Compiler: Translates high-level language into machine code.
• Interpreter: Directly executes high-level language code without compiling.

Explanation

Information is the output from a computer that results from processing input data.

Data is the input, and the computer processes it to produce useful information.

Data (input) → Processing → Information (output)

Explanation

Input, processing, output, and storage are the four primary components of the information processing cycle.

It is also known as the data processing cycle or the computer processing cycle.

Explanation

A supercomputer is another name for a high-performance computer (HPC).

Supercomputers are powerful computers that are designed to execute a large number of instructions at an extremely high speed.

It making them ideal for scientific simulations, weather forecasting, cryptography, and other compute-intensive tasks.

Explanation

A cathode ray is a stream of electrons that are emitted from a cathode (negative electrode) in a vacuum tube.

These electrons carry a negative charge, as they are negatively charged particles.
