Basic Computer Test Quiz: Trivia

The brain of a computer system is called the CPU, or Central Processing Unit. It is responsible for executing instructions and performing calculations, making it the most essential component of a computer. The CPU processes data and controls the other hardware components, allowing the computer to perform various tasks and operations. Unlike a mouse, motherboard, or vacuum tubes, the CPU is specifically designed for processing and controlling data, making it the correct answer.

CD stands for compact disk. It is a storage medium that is used to store and play back digital information. The term "compact" refers to the small size of the disk compared to other storage mediums at the time of its introduction. The disk is capable of storing large amounts of data, such as audio, video, and computer files. Therefore, the correct answer is "compact disk".

HTML stands for Hyper Text Markup Language. It is a standard markup language used for creating and structuring web pages. HTML uses tags to define the structure and layout of a webpage, including headings, paragraphs, images, links, and other elements. The correct answer, "Hyper text markup Language," accurately represents the acronym and its meaning.

A monitor is not considered an input device because it is used to display output from a computer rather than to input data or commands. Input devices are used to provide data or instructions to a computer, such as a keyboard for typing, a scanner for converting physical documents into digital files, and a mouse for controlling the cursor on the screen.

The Central Processing Unit (CPU) is the administrative section of the computer system. It is responsible for executing instructions, performing calculations, and coordinating the activities of all the other hardware components. The CPU acts as the brain of the computer, processing data and controlling the overall operation of the system. It receives input from the input unit, accesses and stores data in the memory unit, and uses the control unit to manage and coordinate the flow of data and instructions within the computer system.

A Storage Area Network (SAN) is a specialized high-speed network that connects servers to storage devices such as disk arrays or tape libraries. It provides block-level storage that can be accessed by multiple servers, allowing for centralized storage management and improved data availability. SANs are commonly used in enterprise environments where large amounts of data need to be stored and accessed efficiently.

The full form of SAD in terms of computers is System Analysis and Design. This refers to the process of studying a system, identifying its components and their interactions, and creating a design to improve its efficiency and effectiveness. It involves analyzing the requirements, designing the system architecture, and planning the implementation. Storage and data and Store Analysis and Design are incorrect options as they do not represent the correct full form of SAD in the context of computers.

The correct answer is "Multi national company". MNC stands for Multi national company, which refers to a corporation that operates in multiple countries and has a presence in various global markets. These companies typically have headquarters in one country and subsidiaries or branches in other countries, allowing them to conduct business on an international scale.

A campus area network (CAN) refers to a network that connects multiple buildings within a limited geographic area, such as a university campus or a corporate office park. This network allows for communication and data sharing between different buildings and departments within the same organization. Therefore, the full form of CAN is "campus area network".
