It first searches for the word in level-1. Let us first examine some common terminology related to memory. If the word is not found in cache, it is in main memory then it counts as a miss. Traditional concepts such as pipelining, instruction-level parallelism, memory hierarchies, and input/output architectures will be discussed. The data or contents of the main memory that are used again and again by CPU, are stored in the cache memory so that we can easily access that data in shorter time. These instructions may be executed in the following two ways- Tentative topics will include computer organization, instruction set design, memory system design, pipelining, and other techniques to exploit parallelism.
