Computer Fundamentals and System Concepts

It consists of control unit, antennas, power plant and data terminals.

A computer virus is a malicious piece of code or program that attaches itself to legitimate programs and replicates by infecting other programs or files. The term virus is used metaphorically from biological viruses. Disease is not a technical term for malicious code, both 1 and 2 is incorrect since disease is not a valid option, and D is wrong because B is the correct answer (despite the typo viruse instead of virus).

A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers, often using a computer network.

Robustness is the ability of a system to continue operating correctly despite invalid inputs or stressful conditions, distinguishing it from general reliability.

A computer program that mimics the behavior of a physical system is called a simulation. It allows researchers to study the system without needing the physical entity.

Cassette is used in Video Player same as Floppy is used in Computer.

Embedded computers are specialized computing systems designed to perform dedicated functions within a larger mechanical or electrical system, such as appliances, vehicles, or thermostats.

System software, such as the operating system, acts as an interface between the computer hardware and the application software, allowing them to communicate and function effectively.

Boot sector viruses infect the master boot record or the boot sector of a storage medium. Historically, these were commonly spread via infected floppy disks left in the drive during startup.

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

A chip is the common term for an integrated circuit, which is a small semiconductor wafer on which thousands or millions of tiny resistors, capacitors, and transistors are fabricated.

Documentation refers to the instructional materials, including manuals, that explain how to install, use, and troubleshoot a software program.

A Graphical User Interface (GUI) allows users to interact with electronic devices through graphical icons and visual indicators, rather than text-based command lines.

Malware is the umbrella term for any software intentionally designed to cause damage to a computer, server, client, or computer network, including viruses, worms, and Trojans.

A time bomb is a type of malware that remains dormant until a specific date or time is reached, at which point it executes its malicious payload.
