What are the two main types of computer memory?

Two main types of computer memory.

• Primary memory for active tasks.

• Secondary memory for long-term storage.

• CPU accesses primary memory directly.

Fill in the blank: RAM stands for ___.

Random Access Memory

True or False: Secondary memory is volatile and loses data when power is removed.

False. Secondary memory is non-volatile and retains data without power.

What is the primary purpose of cache memory?

Cache memory serves to store frequently used data and instructions close to the CPU to reduce average access time.

Riddle: I am a type of memory that needs power to retain data and is faster than my counterpart. What am I?

RAM (Random Access Memory)

Fill in the blank: The access time of memory refers to the ___ between a request and data availability.

Delay

Which type of memory is used for firmware storage and retains data without power?

Read-Only Memory (ROM)

What is one key characteristic that differentiates Dynamic RAM (DRAM) from Static RAM (SRAM)?

DRAM requires periodic refresh cycles to retain information, while SRAM does not require refresh as long as power is supplied.

MCQ: Which type of secondary memory has the highest access latency? A) SSD B) HDD C) USB Flash Drive D) RAM

B) HDD

What technology allows programs to run as if they have more main memory than physically available?

Virtual memory
