Answer 1

Answer:

C. 2

There are two main types of computer memory:

1. Primary Memory / Main Memory: This is the memory that provides information directly to the CPU. It is faster.

• RAM (RAM - Random Access Memory): This is a temporary storage. The necessary information and programs are stored in RAM while the computer is running. The information in this is lost when the computer is turned off (Volatile Memory).

• ROM (ROM - Read-Only Memory): Information is permanently recorded in it when the computer is built. It can only be read, not rewritten. The information in this is not lost even if the computer is turned off (Non-Volatile Memory).

  2. Secondary Memory / Auxiliary Memory: This is the memory used to permanently store large amounts of information. The CPU cannot access it directly, this is done through primary memory. It is slower than primary memory and has a larger storage capacity.

• Hard Disk Drive (HDD)

• Solid State Drive (SSD)

• USB Flash Drive (Pen Drive)

• CD/DVD

• Memory Cards
