Basic Computer Knowledge Quiz

Antivirus is considered software because it is a program that is designed to detect, prevent, and remove malicious software from a computer system. It is specifically developed to protect the computer from viruses, malware, and other harmful threats. Unlike the other options listed (mouse, keyboard, and monitor) which are hardware components, antivirus is a software application that can be installed and run on a computer to provide security and protection.

A sound card is indeed a small circuit board that is necessary for producing high-quality music, narration, and sound effects. It is responsible for converting digital audio signals into analog signals that can be played through speakers or headphones. Without a sound card, the audio quality may be poor and lack the necessary clarity and depth. Therefore, the statement that sound card is required for high-quality music, narration, and sound effects is true.

The word "Peripherals" does not belong because it is the only word that does not refer to a type of software or program. "Applications," "Programs," and "Software" are all terms used to describe different types of software, whereas "Peripherals" refers to external devices or hardware that are connected to a computer.

Charles Babbage is considered the inventor of computers because he designed the first mechanical computer, known as the Analytical Engine, in the 19th century. Although the Analytical Engine was never built during Babbage's lifetime, his designs laid the foundation for modern computer systems. Babbage's work included concepts like punch cards for input and output, a control unit, and a memory system, which are fundamental components of computers today. His contributions to the field of computing make him widely recognized as the inventor of computers.

A computer monitor is a type of output device. It displays the visual output of a computer, such as text, images, and videos, allowing users to view and interact with the information being processed by the computer. The monitor receives signals from the computer's software and translates them into a visual display that can be seen by the user. Unlike storage devices, which are used to store and retrieve data, a computer monitor does not have the capability to store information. Therefore, the correct answer is "Output."

A supercomputer is the most powerful type of computer. It is designed to perform complex calculations and process large amounts of data at incredibly high speeds. Supercomputers are used for tasks such as weather forecasting, scientific research, and simulations that require massive computational power. They have a much higher processing speed and storage capacity compared to microcomputers or mainframe computers, making them ideal for handling complex and resource-intensive tasks. Therefore, a supercomputer is the correct answer as it is specifically designed to provide the highest level of computing power.

The CPU (Central Processing Unit) is the primary component of a computer that performs most of the processing inside a system. It follows the fetch-decode-execute cycle to retrieve instructions from memory, decode them to understand the task, and execute the required operations. The CPU is often referred to as the brain of the computer due to its critical role in processing instructions.

CDs or DVDs are not software devices. They are physical storage media used to store software or other data. Software devices refer to hardware components or peripherals that are specifically designed to run or support software, such as a printer or a scanner. CDs or DVDs themselves do not have the capability to run or support software on their own. Therefore, the correct answer is False.

ROM stands for Read-Only Memory. It is a type of permanent memory that is built into a computer. ROM is non-volatile, meaning it retains its data even when the computer is turned off. It is called "read-only" because the data stored in ROM cannot be easily modified or erased by normal computer operations. ROM is used to store firmware, which includes the computer's basic input/output system (BIOS) and other essential software that is required for the computer to start up.

Input devices are peripherals used to provide data and control signals to a computer. The mouse, keyboard, scanner, microphone, and digital camera are all input devices. Printers and monitors are output devices, while speakers are also output devices. A compact disc (CD) is a storage medium rather than an input device.
