21.
RAM stands for?
Correct Answer
C. Read Access Memory
Explanation
RAM stands for Read Access Memory. It is a type of computer memory that allows data to be read and written quickly. Unlike Read Only Memory (ROM), which is non-volatile and retains data even when the power is turned off, RAM is volatile and requires constant power to retain data. It is used by the computer's operating system and applications to temporarily store data that is actively being used, allowing for faster access and processing speed.
22.
ROM stands for?
Correct Answer
D. Read Only Memory
Explanation
ROM stands for Read Only Memory. It is a type of computer memory that is non-volatile, meaning it retains its data even when the power is turned off. The data stored in ROM cannot be easily modified or erased, hence the name "Read Only." It is commonly used to store firmware and software instructions that are permanently programmed during manufacturing and cannot be changed by normal computer operations. ROM is widely used in devices such as game consoles, smartphones, and embedded systems where permanent storage of data or instructions is required.
23.
A memory that is stored on the computer while it is in operation. Once the computer is turned off, the content is erased.
Correct Answer
A. RAM
Explanation
RAM stands for Random Access Memory. It is a type of computer memory that stores data and instructions that are currently being used by the computer while it is in operation. RAM is volatile, which means that its contents are erased when the computer is turned off or restarted. This makes it a temporary storage for data and programs, allowing for quick access and retrieval by the computer's processor.
