Computer Fundamentals and System Concepts

Some viruses infect the boot sector of the hard disk, so when the machine is booted, the virus gets to run.

A virus is a malicious software program designed to replicate itself and spread to other computers, often causing harm to data, software, or system performance. It is specifically a destructive program, not an operating system or useful hardware/software.

Windows 98 supported all three features: Plug and Play for automatic hardware detection, built-in tools for creating web pages (FrontPad/Personal Web Server), and preemptive multitasking for running multiple applications. Therefore 'All of these' is correct.

The Operating System is responsible for all fundamental resource management including memory, CPU, processes, and devices. Applications run on top of the OS and request resources through it. Memory management is a core OS function, not handled by individual applications.

Booting is the process of loading the operating system into memory when a computer is powered on, derived from 'pulling oneself up by bootstraps'. Formatting erases disk contents, downloading/uploading involve data transfer over networks - none describe the OS loading process.

System software (including the operating system and boot programs) is used to start the computer. A compiler translates code, an interpreter executes code, and boot is the process itself, not the program type.

Software is the set of instructions that tells a computer how to perform a particular task. It includes programs, applications, and operating systems that enable the hardware to function. An interpreter and compiler are specific types of software that process code, while a controller is a hardware component that manages operations.

Software piracy refers to the unauthorized copying, distribution, or modification of software. People who engage in these illegal activities are specifically called 'software pirates,' making option B correct. Hackers may break into systems, but that doesn't necessarily involve software piracy.

A computer virus is a type of malware that, when executed, replicates by modifying other computer programs and inserting its own code. This distinguishes it from other malware types like Trojans (which disguise themselves but don't replicate) and worms (which are standalone and spread through networks).

This technology includes a set of 57 instructions resulting in increasing multimedia capabilities of a computer chip.

This technology introduced k6 chips, feature MMX technology and provides potential power of personal computer.

Disc Controller enables the CPU to communicate with a hard disk, floppy disk or other kind of disk drive.

This type of computers can be accomplished on shared memory systems with multiple CPUs or on distributed memory clusters made up of smaller shared memory systems or single CPU systems.

This function of operating system controls peripheral devices by sending them commands in their proprietary command language.

A user manual (or user guide) is specifically designed to tell end users how to operate and use a software program effectively. Documentation (A) is broader and includes technical specifications, programming manuals are for developers, and technical manuals may cover installation or maintenance rather than usage.
