Mrs Ts 5th And 6th Gr Computer Hardware Quiz

Explanation
The keyboard and mouse are considered input devices because they allow the user to input data or commands into a computer system. The keyboard allows the user to type letters, numbers, and other characters, while the mouse allows the user to move a cursor on the screen and select objects or options. Both devices send signals to the computer, which then processes the input and performs the corresponding actions. The printer and icon, on the other hand, are not input devices. The printer is an output device that produces physical copies of digital documents, and the icon is a graphical representation of a program or file on the computer screen.

Explanation
A flash drive has the most storage space among the given removable storage devices. This is because flash drives can typically hold larger amounts of data compared to CDs and floppy disks. Flash drives are available in various capacities, ranging from a few gigabytes to several terabytes, whereas CDs usually have a storage capacity of around 700 megabytes and floppy disks can only hold a few megabytes of data. Therefore, a flash drive is the best option for storing large 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 should only be done as a last resort when the computer becomes unresponsive or frozen. In normal circumstances, it is recommended to use the proper shut down procedure to avoid potential data loss or damage to the system.

Explanation
The two indications that the computer is on are:
1. If you move the mouse, the icons will appear on the monitor. This suggests that the computer is active and responding to user input.
2. The computer lights on the keyboard may blink briefly. This indicates that the computer is receiving power and is in an operational state.

Explanation
An output device is a peripheral device that receives information from a computer and displays or presents it to the user. A printer is an output device that produces a hard copy of documents or images. Speakers are also considered output devices as they receive audio signals from the computer and produce sound. Both printers and speakers fulfill the criteria of receiving information from the computer and presenting it to the user, making them suitable choices for output devices.

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 the correct answer because the Start button is typically located on the Desktop, and clicking on it brings up a menu that includes the Shut Down option. By selecting Shut Down, you initiate the process of shutting down the computer properly. The other options mentioned, such as All Programs> Log Off and Internet Explorer, are not relevant to shutting down the computer from the Desktop.

Explanation
The cursor refers to the blinking line on the screen that indicates the current position of the user. It is used to select, edit, and navigate through text or other elements on the screen. The cursor can be moved using the keyboard or mouse, and its appearance may vary depending on the application or operating system being used.

Explanation
You should never eat, drink, or spill liquid on a computer because it can cause damage to the hardware and potentially short-circuit the electrical components. Liquids can also cause corrosion and lead to permanent damage. Additionally, food particles can get inside the keyboard or other parts of the computer, which can affect its performance and functionality. It is important to keep food and drinks away from the computer to maintain its proper functioning and prevent any accidents.

Explanation
An icon is a small graphical representation that represents a program or file. When clicked on, it opens the corresponding program or file. Icons are commonly used on desktops, taskbars, and in file explorers to provide a visual way for users to access and open their desired programs or 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 is the main component that controls the overall operation of the computer. The CPU is housed inside the computer tower and is responsible for processing data, managing memory, and controlling the other components of the computer system. Therefore, it is the correct answer to the question as it fits the description of being the "brains" of the computer and being located inside the tower.

Explanation
A mouse is a hardware device that allows you to click and drag. It has buttons that can be clicked to perform various functions, and it also has a tracking mechanism that allows you to move the cursor on the screen by sliding it across a surface. This functionality makes it possible to select and move files, objects, or text by clicking and dragging them with the mouse. A printer, on the other hand, is a device that produces a physical copy of documents or images, and a keyboard is an input device used for typing text or commands into a computer.

Explanation
The given answer is incorrect. The correct answer should be Monitor, CPU/Tower/System Unit, RAM, Mouse, and Keyboard. The printer is not a major hardware component of a desktop computer, as it is an external peripheral device used for printing purposes. RAM, on the other hand, is a crucial component of a computer that stores data for immediate access by the CPU.

Explanation
The mouse is considered the hand of the computer because it is the primary input device used to control the cursor on the screen. It allows the user to navigate and interact with various elements on the computer screen by moving the mouse and clicking its buttons. The mouse is essential for tasks such as selecting, dragging, and dropping files, as well as clicking on icons, buttons, and menus. Without a mouse, it would be challenging to perform many tasks on a computer efficiently.

Explanation
A monitor is a TV looking device that allows you to see images. It is commonly used as a display screen for computers, televisions, and other electronic devices. Monitors come in various sizes and resolutions, and they provide a visual output by displaying images and videos. They are essential for viewing and interacting with digital content, making them a crucial component in the world of technology.

Explanation
A monitor is the correct answer because it is a device that displays visual output from a computer or other electronic devices. It allows users to see images, videos, and other visual content. Keyboards and printers do not have the capability to display images, making them incorrect options.
