Computer Fundamentals and System Concepts

The source code is the original set of instructions written by programmers. Without it, it is impossible to modify or update the software, making it the most critical missing component for system maintenance.

Artificial Intelligence (AI) is the field of computer science dedicated to creating systems capable of performing tasks that typically require human intelligence, such as reasoning, learning, and problem-solving.

An integrated circuit (IC) is a set of electronic circuits on one small flat piece (chip) of semiconductor material, usually silicon, which functions as a single unit.

An operating system (OS) is the system software that manages computer hardware, software resources, and provides common services for computer programs.

A modem (modulator-demodulator) is a hardware device that converts data between digital signals used by computers and analog signals used by telephone lines.

A computer executes instructions contained within a program. While programs are built using algorithms, the computer itself executes the compiled or interpreted program code.

The Central Processing Unit (CPU) is often referred to as the brain or heart of the computer because it performs the primary calculations and logic operations.

Fourth generation computers mainly used in VLSI and LSI technology,  VSI -Large scale Integrated circuits and VLSI - Very large scale integrated circuits.

All the above answers are incorrect. The sequence of microinstruction is called microprogam.

A computer network is a telecommunications network, which allows computers to exchange information. It is a group of two or more computer systems linked together.

A process is an instance of a computer program that is being executed. It contains the program code and its current activity.

A loader which combines the functions of a relocating loader with the ability to combine a number of program segments that have been independently compiled into an executable program.

A virus protection software is designed to prevent viruses, worms and trojan horses from getting into a computer as well as remove any malicious software code.

It is a software that manages all the system resources to provide services that allows various applications to be executed.
