Computer Fundamentals and System Concepts

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.

A backup encompasses the creation of an exact copy of data to protect against loss, the process of restoring that data, and the overall strategy to ensure system availability after a failure.

Computer viruses typically affect software, data, or system behavior. A CD-ROM drive stopping is almost always a hardware failure rather than a software-based virus symptom.

In computing, a cluster is a group of linked computers or terminals that work together closely so that they can be viewed as a single system.

Auto boot (or automatic booting) refers to the process where a computer automatically loads and runs specific programs or the operating system upon being switched on.

It is the initial process of the system.

Mainframes are large, powerful computers designed to handle massive amounts of data and support many users; they are typically housed in large cabinets or frames.
