Fundamentals Of Computer Quiz

Explanation
The gigabyte is the largest unit of data storage in the given list. It is larger than the kilobyte, megabyte, and byte. A gigabyte is equal to 1,024 megabytes or approximately 1 billion bytes. It is commonly used to measure the capacity of computer hard drives, memory cards, and other storage devices.

Explanation
Commanding a computer to create a real sandwich is not possible because a computer is a machine that operates on digital information and does not have the physical capabilities to prepare or create a real sandwich.

Explanation
A keyboard is an input device because it allows the user to input data or commands into a computer. Users can type letters, numbers, and symbols on the keyboard, which are then recognized by the computer and displayed on the screen. Unlike a monitor or printer, which are output devices, a keyboard is specifically designed for inputting information into the computer system. Therefore, the correct answer is Keyboard.

Explanation
Today's computer is used for a variety of purposes including data storage, computing, and playing games. Data storage is one of the fundamental functions of a computer, allowing users to store and retrieve large amounts of information. Computing refers to the ability of a computer to perform calculations and process data, which is essential for tasks such as data analysis, software development, and scientific simulations. Additionally, computers are commonly used for playing games, whether it be casual mobile games or high-performance gaming on dedicated gaming PCs. Therefore, the correct answer is "All of the above."

Explanation
The speed of a computer is measured in Hertz. Hertz is a unit of frequency that represents the number of cycles per second. In the context of a computer, it refers to the number of instructions or operations the computer can perform in a second. The higher the Hertz value, the faster the computer can process data and perform tasks. Therefore, Hertz is the appropriate unit of measurement to quantify the speed of a computer.

Explanation
A DVD Reader is specifically designed to read DVD Rom discs. It is not capable of reading a hard disk or flash memory. Therefore, the correct answer is DVD Rom.

Explanation
A scanner is a device that converts a picture on paper to an electronic image on the computer. It uses optical sensors to capture the image and then converts it into a digital format that can be stored and manipulated on a computer. This allows for easy sharing and editing of physical documents, such as photographs or text, in a digital form.

Explanation
A printer is a device that is used to generate an image on a paper from the computer. It takes digital information from the computer and converts it into a tangible printout on paper. Scanners, on the other hand, are used to convert physical documents or images into digital format, while a mouse is an input device used to control the cursor on a computer screen. A monitor is a display device that shows the output of the computer. Therefore, the correct device to generate an image on paper from the computer is a printer.

Explanation
The computer's monitor is responsible for displaying the data of the computer. It is the output device that shows the information processed by the computer's hardware and software to the user. The monitor visually presents text, images, videos, and other graphical elements that are generated by the computer. It allows the user to interact with the computer by providing a visual interface for viewing and manipulating data.

Explanation
Among the given options, the mouse is the smallest in size. Keyboards and monitors are typically larger in size, while printers can also be quite bulky. On the other hand, a mouse is a compact device that is designed to fit comfortably in the hand and is usually much smaller compared to the other options.
