MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Cache memory is sometimes called CPU (central processing unit) memory because it is typically integrated directly into the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.

Detailed explanation-2: -Cache is the temporary memory officially termed “CPU cache memory.” This chip-based feature of your computer lets you access some information more quickly than if you access it from your computer’s main hard drive.

Detailed explanation-3: -Memory caching (often simply referred to as caching) is a technique in which computer applications temporarily store data in a computer’s main memory (i.e., random access memory, or RAM) to enable fast retrievals of that data. The RAM that is used for the temporary storage is known as the cache.

Detailed explanation-4: -The cache augments, and is an extension of, a computer’s main memory. Both main memory and cache are internal random-access memories (RAMs) that use semiconductor-based transistor circuits. Cache holds a copy of only the most frequently used information or program codes stored in the main memory.

Detailed explanation-5: -Explanation: To reduce memory access time, a small, fast memory is inserted between the main memory and the processor. This Memory is called Cache Memory.
