A Quiz For Kids: Very Basic Questions On Computer

Explanation
The correct answer is "An electronic device" because a computer is a machine that can perform various tasks by executing a set of instructions. It uses electronic components and circuits to process and store data, and it can also receive input from users and provide output through various devices. Therefore, describing a computer as an electronic device is an accurate and comprehensive explanation.

Explanation
It can do anything; From calculating big numbers, solve various mathematical problems, control machines, etc.

Explanation
The given list includes various parts of a computer, such as a keyboard, smartphone, and rat. However, the correct answer is "keyboard" because it is the only item in the list that is a recognized component of a computer. A keyboard is an input device that allows users to input data and commands into a computer system. The other options, smartphone and rat, are not typically considered parts of a computer.

Explanation
Computers are commonly found in schools as they are extensively used for educational purposes. They are used by students for research, completing assignments, and accessing online learning resources. Teachers also use computers for lesson planning, creating presentations, and grading assignments. Additionally, schools often have computer labs equipped with multiple computers for students to use. Therefore, the correct answer is "School".

Explanation
Accuracy is one of the features of a computer. It refers to the ability of a computer to perform tasks with precision and without errors. Computers are designed to execute instructions accurately, making them reliable for tasks that require precise calculations or data processing. This feature ensures that the output generated by a computer is consistent and dependable, which is crucial in various fields such as finance, engineering, and scientific research.

Explanation
Input devices are devices that allow users to input data or commands into a computer system. They are used to interact with the computer and provide input for processing. The mouse is an example of an input device as it allows users to move the cursor and select objects on the screen. It is used to navigate and interact with graphical user interfaces. Therefore, the correct answer is Mouse.

Explanation
A joystick is a common input device used to control the movement and actions of characters or objects in video games. It typically consists of a handheld stick that can be tilted or moved in different directions to provide input to the game. By manipulating the joystick, players can navigate through virtual environments, control the movement of their characters, and perform various in-game actions. Therefore, the statement that a joystick is used to play video games is true.

Explanation
The correct answer is Central Processing Unit. The CPU, or Central Processing Unit, is the primary component of a computer that performs most of the processing inside the computer. It interprets and executes instructions from the computer's memory, allowing it to perform tasks and run programs. It is often referred to as the "brain" of the computer, as it carries out the majority of the computer's operations.

Explanation
The correct answer is Cathode Ray Tube. CRT stands for Cathode Ray Tube, which is a technology used in older television and computer monitors. It is a vacuum tube that uses electron beams to create images on a fluorescent screen. This technology was widely used before the advent of LCD and LED screens.

Explanation
The correct answer is "Printer" because it is the only device listed that is specifically designed to produce a hard copy of digital information onto paper. The other devices listed, such as the mouse, monitor, and processor, are not output devices. The mouse is an input device used to control the cursor on the screen, the monitor is a display device for visual output, and the processor is a component of a computer system responsible for executing instructions.
