Practical Quiz-1 Grade 1

The statement is true because a keyboard does indeed have both letter keys and number keys on it. The letter keys are used for typing letters of the alphabet, while the number keys are used for typing numbers. This is a basic feature of a standard keyboard layout, making the statement accurate.

A printer is a device that can print words and pictures from a computer. It is commonly used to produce hard copies of documents or images. Unlike a speaker, mouse, or monitor, which have different functions, a printer is specifically designed for printing purposes. Therefore, a printer is the correct answer for this question.

A monitor is a device that displays words, videos, and pictures on a screen. It is the primary output device of a computer system, allowing users to view and interact with the information being displayed. The keyboard and mouse are input devices, allowing users to input commands and interact with the computer, while the CPU is the central processing unit responsible for executing instructions and processing data. However, none of these devices specifically display visual content on a screen like a monitor does.

Input devices are indeed used to enter data into a computer. These devices include keyboards, mice, scanners, and microphones, among others. They allow users to input commands, text, and other forms of data into the computer system for processing and storage. Therefore, the statement "Input devices are used to enter data to computer" is correct.

The processor is often referred to as the "brain" of the computer because it is responsible for executing instructions, performing calculations, and managing data flow within the computer system. It is the central component that carries out all the necessary tasks to ensure the computer functions properly. The keyboard, speaker, and monitor are peripheral devices that provide input, output, and display capabilities, but they do not have the same level of control and processing power as the processor. Therefore, the processor is the correct answer as it plays a crucial role in the overall functioning of the computer.

The device being referred to in the question is a keyboard. A keyboard is an input device that allows the user to input text, numbers, and commands into a computer or other electronic device. It typically consists of a set of keys, including letters, numbers, symbols, and function keys, arranged in a specific layout. The answer options provided in the question all correctly identify the device as a keyboard, with different capitalization variations.

The given question is incomplete and does not provide enough information to determine the correct answer. Without more context, it is not possible to determine what type of device the speaker is referring to. Therefore, an explanation cannot be provided.

The correct answer is "Monitor" because it is the name of the device being referred to in the question. In this case, the word "Monitor" is spelled in different cases (lowercase and uppercase) but it still refers to the same device.

Keyboard and mouse are both examples of input devices. A keyboard allows the user to input text and commands by pressing keys, while a mouse allows the user to control the cursor and interact with graphical user interfaces by moving and clicking. Both devices transmit data from the user to the computer, making them input devices.

A monitor is an output device because it displays visual information from the computer. It allows users to view the output such as text, images, videos, and graphics produced by the computer. The other options listed, keyboard, mouse, and scanner, are all input devices as they allow users to input data or commands into the computer.
