The four types of memory in a computer are: RAM (Random Access Memory) for temporary storage, ROM (Read-Only Memory) for permanent storage, Cache for high-speed data access, and Virtual Memory which extends RAM capacity by using disk storage.

FAQs & Answers

  1. What is the difference between RAM and ROM? RAM is temporary memory used for active processes, while ROM is permanent memory storing essential system instructions.
  2. How does cache memory improve computer performance? Cache memory stores frequently accessed data at high speeds, reducing the time it takes for the CPU to retrieve information.
  3. What role does virtual memory play in a computer? Virtual memory extends the usable RAM by using disk storage, allowing the system to handle larger workloads than physical RAM alone.
