Answer 1

The correct answer is: 4) An independent memory module that can be accessed concurrently

A memory bank is a logical or physical unit of RAM that can be accessed independently and simultaneously by the memory controller.
It consists of multiple memory chips working together as a single module (e.g., a DIMM in modern systems).
Banks enable parallel data access, improving memory bandwidth and performance.

Cache memory location → Incorrect, as cache is a separate high-speed memory layer.
Group of memory cells in a single row → Describes a memory row, not a bank.
Section reserved for the OS → Refers to kernel memory, not a bank.
