Mrs Ts Computer Hardware Basics 2nd & 3rd Grade

Explanation
A monitor is a TV-like device that allows you to see images. It is commonly used as a display screen for computers or other electronic devices, providing visual output to the user. Monitors come in various sizes and resolutions, and they are essential for viewing and interacting with digital content. They can display images, videos, text, and other graphical elements, making them an integral part of any visual communication system.

Explanation
The keyboard and mouse are considered input devices because they allow the user to input data into the computer. The keyboard allows the user to type letters, numbers, and other characters, while the mouse allows the user to move the cursor on the screen and click on icons or buttons. Both devices provide a way for the user to interact with the computer and input commands or information.

Explanation
The correct answer is 3-1/2" Floppy disk because it is a type of removable storage device that was commonly used in the past. It was a small, square-shaped disk that could store a limited amount of data. Compact Disc refers to a different type of removable storage device that uses optical technology, while a flash drive is a modern portable storage device that uses flash memory.

Explanation
A flash drive has the most storage space among the given removable storage devices. This is because flash drives are typically available in larger storage capacities compared to CDs and floppy disks. CDs usually have a storage capacity of around 700MB to 1.4GB, while floppy disks have a maximum capacity of 1.44MB. On the other hand, flash drives can have storage capacities ranging from a few gigabytes to several terabytes, making them capable of storing much larger amounts of data.

Explanation
The correct answer is "Never, unless the computer stops responding." This is because pressing the power button to turn off the computer can cause data loss and potential damage to the system. It is recommended to use the proper shutdown procedure through the operating system, unless the computer becomes unresponsive and cannot be shut down through normal means.

Explanation
The two indications that the computer is on are: 1) If you move the mouse, the icons will appear on the monitor, and 2) The computer lights on the keyboard may blink briefly.

Explanation
An output device is a peripheral device that receives data from a computer and presents or displays the processed information. In this case, both the printer and speakers can be considered output devices. The printer receives digital data from the computer and produces a hard copy output in the form of text or images. Similarly, the speakers receive audio data from the computer and produce sound output. Both devices serve the purpose of presenting information or data in a tangible or audible form.

Explanation
To shut down the computer from the Desktop, you should click on the Start button and then select the Shut Down option. This is a common method used in most operating systems to initiate the shutdown process. By clicking on Start and choosing Shut Down, the computer will go through the necessary steps to safely power off and terminate all running processes. The other options mentioned, such as logging off or opening Internet Explorer, are not relevant to shutting down the computer.

Explanation
The cursor is the blinking line that indicates the current position on the screen. It is used to show where the next input or action will take place, such as typing or clicking. The cursor helps users navigate and interact with the screen by visually indicating their location and allowing them to select or modify content.

Explanation
Eating, drinking, or spilling liquid on a computer should never be done because it can cause damage to the hardware components and lead to malfunctioning. Liquids can seep into the keyboard or other parts of the computer, causing short circuits and corrosion. This can result in permanent damage to the computer and may require costly repairs or replacement. It is important to keep food and beverages away from the computer to ensure its proper functioning and longevity.

Explanation
An icon is a small graphical representation that represents a program or file. When clicked on, it opens the program or file associated with it. Icons are commonly used on desktops and in file managers to provide a visual way for users to access and launch applications or open files.

Explanation
The CPU, or Central Processing Unit, is often referred to as the "brains" of the computer because it is responsible for executing instructions and performing calculations. It controls the operation of other hardware components, including the hard drive and memory, and is typically housed inside the computer tower. The CPU is essential for processing and managing data, making it a fitting choice for the device that serves as the "brains" of the computer.

Explanation
The correct answer is mouse because it is a hardware device that allows you to click and drag. Unlike a printer, which is used for printing documents, or a keyboard, which is used for typing, the mouse is specifically designed for navigating and interacting with graphical user interfaces by clicking and dragging objects on the screen.

Explanation
The correct answer includes the major hardware components of a desktop computer. The monitor is responsible for displaying the visual output, while the CPU/Tower/System Unit houses the central processing unit and other essential components. The printer is an output device that allows for physical copies of documents or images. The mouse and keyboard are input devices used for interacting with the computer and providing commands. RAM, or random access memory, is a crucial component for temporary data storage and quick access by the CPU.

Explanation
The mouse is considered the hands of the computer because it is the primary input device that allows users to interact with the computer by pointing, clicking, and dragging objects on the screen. It provides a way for users to control the cursor and navigate through menus, windows, and applications. Without a mouse, it would be difficult to perform tasks such as selecting text, opening files, or navigating the internet. Therefore, the mouse is an essential tool that mimics the functionality of human hands and enables precise control and manipulation of the computer's interface.
