ROM
Correct Answer
B. Read Only Memory
Explanation
ROM stands for Read Only Memory. It is a type of computer memory that stores data permanently and cannot be modified or erased by normal computer operations. The data stored in ROM is non-volatile, meaning it is retained even when the computer is powered off. This type of memory is commonly used to store firmware and software instructions that are essential for the computer's operation. Unlike RAM (Random Access Memory), which allows both reading and writing of data, ROM can only be read. Therefore, the correct answer is Read Only Memory.

RAM
Correct Answer
A. Random Access Memory
Explanation
RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. This makes it different from sequential access memory, where data can only be accessed in a specific order. RAM is volatile, meaning its contents are lost when the power is turned off, which is why it is used for temporary storage of data that is actively being used by the computer's operating system and applications.

9.
Mb
Correct Answer
D. Megabyte
Explanation
A megabyte (MB) is a unit of digital information storage or transmission, commonly used to measure file sizes and data transfer rates. It is equal to 1,000 kilobytes or 1,000,000 bytes. In contrast, a megabit (Mb) is a unit of data transfer rate equal to 1,000 kilobits or 1,000,000 bits per second. Megahertz (MHz) is a unit of frequency equal to one million cycles per second. Magabyte is not a recognized unit of measurement. Therefore, the correct answer is Megabyte.
10.
CD-RW
Correct Answer
D. Compact-Disk ReWritable
Explanation
The correct answer is "Compact-Disk ReWritable" because CD-RW stands for Compact-Disk ReWritable. CD-RW is a type of compact disc that can be written, erased, and rewritten multiple times. The other options provided in the question are incorrect as they do not accurately represent the acronym CD-RW.
