MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -When a cache client attempts to access data, it first checks the cache. If the data is found there, that is referred to as a cache hit. The percent of attempts that result in a cache hit is called the cache hit rate or ratio.

Detailed explanation-2: -A cache hit is when a computer processor finds the data it needs inside cache memory. When a program requests data from memory, the processor will first look in the cache. If the memory location matches one of the tags in a cache entry the result is a cache hit and the data is retrieved from the cache.

Detailed explanation-3: -Cache memory is a chip-based computer component that makes retrieving data from the computer’s memory more efficient. It acts as a temporary storage area that the computer’s processor can retrieve data from easily.

Detailed explanation-4: -When data is found in cache memory, this is called a cache hit.

Detailed explanation-5: -A cache miss is an event in which a system or application makes a request to retrieve data from a cache, but that specific data is not currently in cache memory. Contrast this to a cache hit, in which the requested data is successfully retrieved from the cache.
