PC Components Knowledge Test! Quiz

A hard disk can be used to store all types of data, including movies, music, games, and work-related files. It provides a large amount of storage space and is commonly used in computers and other electronic devices to store and retrieve data. Therefore, the correct answer is that a hard disk can store all types of data.

The correct answer is "give electric to the hold computer system." This answer accurately describes the function of a power supply in a computer system. A power supply is responsible for providing electrical power to all the components of a computer, ensuring that they can function properly. Without a power supply, the computer would not be able to receive the necessary electrical energy to operate.

The motherboard is responsible for connecting all devices in the computer system. It acts as a central hub, allowing various components such as the CPU, RAM, storage devices, and peripherals to communicate and work together. Without the motherboard, these devices would not be able to function properly or interact with each other. Therefore, the correct answer is connecting all devices in the computer system.

The memory in a computer refers to the storage space where software applications and data are stored. It allows the computer to access and retrieve information quickly and efficiently. This storage space is essential for the functioning of the computer as it enables the execution of programs and the storage of files and data. Without memory, the computer would not be able to store and access the necessary information required for its operation.

CD-RW stands for Compact Disc Re-Writable. It is a type of CD that can be written, erased, and rewritten multiple times. Unlike regular CDs, which can only be written once, CD-RWs provide the flexibility to store and update data. They are commonly used for data storage, allowing users to save and modify information as needed. They are not specifically designed for watching movies, listening to music, saving work, or installing programs.

The correct answer is "curry out the instruction in a program and control all the components in the computer system." The CPU, or Central Processing Unit, is responsible for executing instructions in a program and coordinating the activities of all the hardware components in a computer system. It performs calculations, manages memory, and controls input/output operations.

The sound card is a hardware component that provides the ability to input and output audio. It allows the user to connect various audio devices such as microphones, speakers, and headphones to the computer. This enables the user to both record audio input, such as voice or music, and play audio output, such as sound effects or music.

The correct answer is "enclosure the hold main component of a compute". This answer suggests that an enclosure is used to hold the main components of a computer. This could refer to a computer case or housing that contains the motherboard, CPU, memory, and other essential components of a computer system.

MS DOS is the correct answer because it is an operating system that relies heavily on a command line interface. Unlike other operating systems that have graphical user interfaces, MS DOS requires users to input commands through a text-based interface in order to interact with the system and execute tasks. This command line interface allows users to directly access and control various functions and processes of the operating system.

CD-ROM is not an example of a system because it is a storage medium rather than a complete functioning system. A computer, car engine, television, and phone are all examples of systems as they consist of multiple components working together to perform specific functions. However, a CD-ROM is simply a type of optical disc that stores data and requires a separate system, such as a computer or CD player, to read and access the data stored on it.

The correct answer is "Computer Aided Design" because CAD is a technology that is used to create, modify, analyze, and optimize designs. It involves the use of computer software and tools to assist in the design process, allowing for more efficient and accurate creation of drawings, models, and prototypes. CAD is widely used in various industries such as architecture, engineering, and manufacturing.
