FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -What is a cache? A cache–pronounced CASH–is hardware or software that is used to store something, usually data, temporarily in a computing environment. It is a small amount of faster, more expensive memory used to improve the performance of recently or frequently accessed data.

Detailed explanation-2: -Cache memory is fast and expensive. Traditionally, it is categorized as “levels” that describe its closeness and accessibility to the microprocessor. There are three general cache levels: L1 cache, or primary cache, is extremely fast but relatively small, and is usually embedded in the processor chip as CPU cache.

Detailed explanation-3: -The big picture: Memory is like desk space Cache is the fastest and most expensive, RAM is slower and less expensive, and virtual memory is the slowest and least expensive type.

Detailed explanation-4: -Cache is the fastest and smallest component of memory in a computer system. The registers are fast storage elements present in a very small amount in the computer processor. The recently used info/data of a computer gets stored in the cache.

Detailed explanation-5: -Cache memory, when compared to RAM memory, is smaller and more expensive but it makes up for that with raw processing power. Up to 100 times faster than DRAM memory. This is wildly helpful in increasing the computer’s speed and efficiency.
