Answer: memory

Explanation:

The correct answer is (c) memory, which is a place in the computer system where data and programs are temporarily stored. There are several types of memory in a computer system, including RAM (Random Access Memory), cache memory, and virtual memory. RAM is the most commonly used type of memory in a computer, and is used to store data and programs that are currently in use by the computer. When the computer is turned off or restarted, the contents of RAM are cleared, which is why it is referred to as "temporary" memory.

Answer: read-only

Explanation:

A disk’s content that is recorded at the time of manufacture and that cannot be changed or erased by the user is (d) read-only. A read-only disk, also known as a CD-ROM (Compact Disc - Read-Only Memory) or DVD-ROM (Digital Versatile Disc - Read-Only Memory), is a type of storage medium that contains pre-recorded data that cannot be altered or erased by the user. The data is permanently etched onto the disk during manufacturing using a laser or other recording technology, and can only be read by a compatible optical disk drive. CD-ROMs and DVD-ROMs are commonly used for distributing software, music, movies, and other media.

Answer: Round

Explanation:

CDs (Compact Discs) are typically circular or round in shape with a diameter of 120 millimeters (4.7 inches). They have a hole in the center and a flat, reflective surface on one side that contains digital data in the form of tiny pits and lands. CDs are a type of optical disc that can store and play back audio, video, and other types of digital information.

Answer: hard disk

Explanation:

The storage device that uses rigid, permanently installed magnetic disks to store data/information is (b) hard disk. A hard disk is a type of storage device that uses rigid, permanently installed magnetic disks to store data and information. It is a non-volatile storage device, which means that it retains its data even when the computer is turned off. Hard disks are commonly used in desktop computers, laptops, servers, and other computing devices to store operating systems, applications, and user data. Hard disks are typically faster and have larger storage capacity than other magnetic storage devices, such as floppy disks and magnetic tape.

Answer: Cache memory

Explanation:

Cache memory acts as temporary high-speed holding area between the memory and the CPU thereby improving processing capabilities.

Answer: Gigabyte

Explanation:

Gigabyte is the second largest measurement of RAM. The largest measurement is Terabyte, followed by Gigabyte, Megabyte, and Byte.

Answer: IBM - 650

Explanation:

The IBM 650 Magnetic Drum Data - Processing Machine is one of IBM's early computers, and the world's first mass-produced computer

Answer: Storage for information and instruction

Explanation:

A storage unit provides storage for information and instructions. Therefore, option (b) is the correct answer.

Answer: Hard Disk Drive

Explanation:

The "Hard Disk Drive" is not considered a removable media because it is installed inside a computer or device and is not designed to be easily removed. Therefore, the answer is (d) Hard Disk Drive. Option (a), (b), and (c) are all examples of removable media because they can be easily inserted into and removed from a computer or device.

Answer: All the above

Explanation:

CD-ROMs (Compact Disc-Read Only Memory) are an optical disc storage media that are widely used for storing large amounts of data and information. They have several advantages over magnetic storage media, such as floppy disks and hard disk drives, including: (a) CD-ROMs are relatively inexpensive to produce, making them an affordable way to store large amounts of data and information. (b) CD-ROMs can retrieve data and information quickly, although they may not be as fast as modern solid-state storage devices like SSDs. (c) CD-ROMs are less prone to errors and data loss than magnetic media, as they use optical technology to read and write data, rather than magnetic fields.
