Introduction To Computer And Windows Seven Test

The given statement is true because hardware refers to the physical components or devices that are used to build a computer system. These components include the central processing unit (CPU), memory, storage devices, input devices (such as a keyboard and mouse), output devices (such as a monitor and printer), and other peripheral devices. Without these physical components, a computer system cannot function. Therefore, it is correct to say that hardware comprises the components or physical devices that make up the computer system.

The task of "switch user" in a computer is to allow multiple users to use the computer without closing any programs that are currently running. This feature is especially useful in shared computer environments or when multiple users need to access their personal accounts without interrupting each other's work. By switching users, each individual can have their own separate session with their programs and files open, ensuring privacy and convenience.

To hide and show file extensions, you can go to the "Tools" menu, then select "Folder Options". In the "View" tab of the Folder Options window, there is an option to "Hide extensions for known file types". If this option is checked, file extensions will be hidden. If it is unchecked, file extensions will be shown.

The answer "input and output" refers to the hardware components of a computer that are responsible for receiving data (input) and delivering processed information (output). Input devices, such as keyboards and mice, allow users to input data into the computer system. Output devices, such as monitors and printers, display or produce the processed information for users to view or utilize. This distinction is important in understanding how data flows into and out of a computer system, enabling communication and interaction between the user and the machine.

There are three types of computers: desktop computers, laptop computers, and tablet computers. Each type has its own unique features and advantages. Desktop computers are typically more powerful and have more storage space, making them suitable for tasks that require high performance, such as gaming or video editing. Laptop computers are portable and convenient for on-the-go use. Tablet computers are compact and touchscreen-based, ideal for casual browsing and entertainment purposes.

The monitor is the most common input and output device. It is used to display information from the computer and also allows users to interact with the computer by providing input through a keyboard or mouse. Therefore, it serves as both an input and output device, making it the correct answer.

The given answer is incorrect. To make a user account in a computer, one can go to the settings or preferences of the operating system and look for an option to create a new user account. The exact steps may vary depending on the operating system being used. The answer provided in the question does not accurately describe the process of creating a user account.

The most common input devices are the keyboard, mouse, and scanner. These devices allow users to input data and commands into a computer system. The keyboard is used for typing text and entering commands, while the mouse is used for pointing, clicking, and selecting objects on the screen. The scanner is used to convert physical documents or images into digital files that can be stored or edited on a computer. These input devices are widely used in various applications and are essential for interacting with a computer system.
