Computer Science

Applications that combine text, sound, graphics, motion video, and/or animation are called multimedia applications because they integrate multiple forms of media.

VLSI stands for Very Large Scale Integration, which refers to the process of creating integrated circuits by combining thousands of transistors into a single chip. This is a fundamental concept in electronics and computer engineering.

VAB commonly stands for 'Voice Answer Back,' which is a telecommunication feature allowing a system to respond with a voice message automatically. This matches option C, making it the correct answer.

VOIP stands for Voice over IP, which refers to the technology that allows voice communication over Internet Protocol networks.

VGA stands for Video Graphics Array, which is a standard for display hardware introduced by IBM. It is widely recognized as the correct expansion of the acronym VGA.

A USB drive is considered a secondary storage device because it is used to store data externally and persistently, unlike primary storage which is typically volatile memory like RAM. Secondary storage devices retain data even when the computer is turned off.

The "I Love You" virus, also known as the Love Bug, is widely recognized as one of the most widespread and damaging computer viruses in history, infecting millions of computers worldwide in 2000. It spread rapidly via email, causing extensive damage and making it the record holder for widespread infection.

URL stands for Uniform Resource Locator, which is the correct and widely accepted full form used to specify addresses on the internet.

Virtual memory is a memory management technique that uses a portion of the hard drive to extend the apparent amount of RAM available to programs. It is typically located on the hard drive, not in RAM, CPU, or flash memory.

DMA stands for Direct Memory Access, a feature that allows hardware subsystems to access main system memory independently of the CPU, improving data transfer efficiency.

An assembler is a translator that converts assembly language programs into machine language code, which can be executed by a computer's CPU. This distinguishes it from compilers and interpreters, which work with higher-level languages, and debuggers, which are used for testing and debugging code.

WAN stands for Wide Area Network, which is a telecommunications network that extends over a large geographical area, connecting multiple smaller networks such as LANs.

Diagnostic software is specifically designed to detect faults and their causes in computer systems, making it the correct answer. The other options do not relate to fault detection.

Vendor-created program modifications intended to update or fix software are commonly called patches. They address bugs, security vulnerabilities, or add minor improvements.

An embedded system is a combination of computer hardware and software designed to perform a dedicated function within a larger mechanical or electrical system. Option D correctly describes this as the computer and software system that control the machine.

Vector graphics are composed of paths, which are defined by mathematical equations representing lines, curves, and shapes. This differs from raster graphics, which are made up of pixels.

A light pen is an optical input device that allows users to interact with a computer screen by detecting light from the screen when the pen touches it. It is not mechanical or electronic in the traditional sense, nor is it an output device.

UTP stands for Unshielded Twisted Pair, which is a type of cable commonly used in networking that consists of pairs of wires twisted together without additional shielding.

Vertical separation between columns in document formatting is referred to as the 'gutter,' which is the space or gap between columns to improve readability and layout clarity.

A website is primarily a collection of web pages that are linked together and accessed via the internet. While websites may contain graphic, audio, and video files, these are components within web pages, not the website itself.

An interpreter translates and executes a program line by line, converting each statement into machine code and running it immediately, unlike a compiler which translates the entire program before execution.

In most word processing software, pressing Ctrl + = applies the Superscript formatting, raising the selected text above the baseline. Ctrl + (plus sign) is typically used for superscript, while Ctrl + (equal sign) is often the same key as plus and triggers superscript. Ctrl + (minus sign) is used for subscript.

A website is not an address itself; rather, it is a collection of web pages accessible via an address called a URL. Therefore, none of the given options correctly define a website.

ROM is non-volatile memory, meaning it retains data even when the power is turned off, which makes it useful for storing firmware and permanent data.

The executable file to start Microsoft Word via the Run dialog box is 'winword.exe'. The other options are incorrect as they do not correspond to the actual executable name for MS Word.
