Student Assessment #2: Parts Of The Computer Quiz

Explanation
Hardware refers to the physical components of a computer that can be seen and touched, such as the monitor, keyboard, mouse, and CPU. These components are tangible and can be physically manipulated. In contrast, software refers to the programs, applications, and data that are stored on the computer and cannot be physically touched. Therefore, hardware is the correct answer as it accurately represents the visible and tangible parts of a computer.

Explanation
A keyboard is mainly used for typing text into a computer. It is an input device that allows users to input letters, numbers, and other characters by pressing the keys. The keyboard is essential for tasks such as writing documents, sending emails, and entering commands. It is a primary tool for communication and data entry on a computer system.

Explanation
Speakers are used to play sound. They are output devices that convert electrical signals into audible sound waves. When audio data is sent to the speakers, they vibrate and produce sound. Speakers are commonly used in various devices such as computers, televisions, and audio systems to provide audio output.

Explanation
A floppy disk is a storage device that is used to store and retrieve data or information. It is a portable and removable storage medium that was commonly used in the past. Floppy disks have a relatively small storage capacity compared to modern storage devices, but they were widely used for saving files, documents, and other data. They were compatible with various computer systems and were convenient for transferring data between different computers. Therefore, the correct answer is that a floppy disk is used for the storage of data or information.

Explanation
A modem is a device that allows computers to connect to the Internet. It converts digital signals from the computer into analog signals that can be transmitted over telephone lines or other communication channels. This enables users to access the Internet and browse websites, send and receive emails, and download/upload files. The modem acts as a bridge between the computer and the Internet service provider, facilitating the transfer of data between the two. Therefore, the correct answer is "connect to the Internet."

Explanation
The system unit is considered the central part of a computer system because it houses the main components that make up the computer, such as the motherboard, processor, memory, and storage devices. It is responsible for processing and managing data, as well as controlling the other peripherals connected to the computer. The monitor, keyboard, and printer are all peripheral devices that interact with the system unit, but they are not considered the central part of the computer system.

Explanation
CDs and DVDs should only be held by the center hole and outer edges to avoid damaging the disc. The center hole is designed to fit onto the spindle of a CD or DVD player, ensuring proper alignment and stability during playback. Holding the disc by the outer edges prevents fingerprints and smudges from coming into contact with the data side of the disc, which can cause read errors or damage. Holding the disc in any other way, such as touching the data side, can lead to scratches, smudges, or even breakage, rendering the disc unusable.

Explanation
Storing CDs and DVDs in a hot, sunny place is not recommended because it can cause damage to the discs. Heat and direct sunlight can cause the discs to warp, which can result in playback issues. It is best to store CDs and DVDs in a cool, dry place away from direct sunlight to ensure their longevity and optimal performance.

Explanation
Returning CDs and DVDs to their cases immediately after use is important because it helps protect them from damage. Leaving them out can lead to scratches, dust accumulation, and potential breakage. By placing them back in their cases, they are kept safe from potential harm and are easily organized for future use. This practice also helps to prevent misplacement or loss of the discs. Therefore, it is advisable to return CDs and DVDs to their cases promptly after use.

Explanation
CDs and DVDs are actually more easily damaged than the hard disk of a computer. While hard disks are enclosed in a protective casing and have no physical moving parts, CDs and DVDs are vulnerable to scratches, cracks, and warping. Even a small scratch can render a CD or DVD unreadable, whereas hard disks are more resilient and can withstand some physical impact. Additionally, CDs and DVDs are sensitive to heat and sunlight, which can cause them to degrade over time. Therefore, the correct answer is false.
