Internal And External Parts Of Computer! Trivia Facts Quiz

Explanation
A modem is a device that connects computers and allows them to communicate with each other over a network. It converts digital signals from the computer into analog signals that can be transmitted over telephone lines or other communication channels. This enables the computers to send and receive data, facilitating communication and sharing of information between them.

Explanation
The CPU (Central Processing Unit) is often referred to as the brain of a computer because it is responsible for executing instructions and performing calculations. It is the component that carries out the majority of the computer's processing tasks, including controlling and coordinating the operations of other hardware components. The CPU is responsible for fetching, decoding, and executing instructions, as well as performing arithmetic and logical operations. It is the primary component that determines the overall speed and performance of a computer system.

Explanation
The power supply is responsible for providing electricity to the computer. It converts the AC power from the wall outlet into DC power that the computer components can use. Without a functioning power supply, the computer would not receive the necessary electricity to operate. Therefore, the power supply is essential for powering the computer and allowing it to function properly.

Explanation
A video card is responsible for handling the display of images and videos on a computer monitor. It processes the data from the computer and converts it into a format that can be displayed on the monitor. Without a video card, the computer would not be able to properly display pictures on the monitor.

Explanation
The correct answer is BIOS. BIOS stands for Basic Input/Output System, which is a firmware that is stored on a chip on the motherboard. It is responsible for initializing and testing hardware components during the computer's startup process. When you wake up the computer, the BIOS is the first software that runs and it performs a series of checks and configurations to ensure that the computer's hardware is functioning properly before handing over control to the operating system.

Explanation
ROM stands for Read-Only Memory. It is a type of computer memory that is non-volatile, meaning it retains its data even when the power is turned off. ROM is used to store permanent instructions for the computer system, such as the firmware or the BIOS. Unlike RAM (Random Access Memory), ROM cannot be modified or written to by normal computer operations. It is typically used to store critical system instructions that are required for the computer to start up and perform basic functions. Therefore, the correct answer is ROM.

Explanation
The correct answer is hardware. Hardware refers to the physical components of a computer that can be seen and touched, such as the monitor, keyboard, mouse, and CPU. Unlike software or ROM, which are not tangible, hardware is the physical part of a computer that allows it to function and interact with users.

Explanation
The given answer, "Software," is the correct answer because software refers to the programs and applications that are installed on a computer system, which are essential for running and performing various tasks. Software acts as the intermediary between the user and the hardware, allowing the user to interact with the computer and utilize its capabilities. Without software, the computer would not be able to process data or perform any functions. Therefore, software is the data or information used to run a computer.
