Which memory type allows random access to memory cells and is used to implement main memory?

• A. Read Only Memory
• B. RAM (Random Access Memory)
• C. Cloud Storage
• D. Cookies

Answer: (B)

Random access to memory cells means you can read or write data at any location in memory in roughly the same amount of time, which is vital for a computer’s working memory. This flexibility lets the CPU fetch instructions and data quickly from anywhere in memory as programs run. RAM provides this capability, making it the memory used to implement main memory. In contrast, read-only memory stores data permanently and isn’t designed for fast, frequent updates during operation; cloud storage is external network-based storage, not the computer’s fast local memory; and cookies are tiny data stored by browsers, not a primary memory type. So the memory that allows random access and serves as main memory is RAM.
