1. cache

   • how
     • Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory.
   • why
     • Search Results Featured snippet from the web Image result for why do we need cache The purpose of cache memory is to store program instructions and data that are used repeatedly in the operation of programs or information that the CPU is likely to need next. The computer processor can access this information quickly from the cache rather than having to get it from computer's main memory.
   • what
     • In Computing Cache is a component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.

2. cores

   • what
     • A processor with two cores is called a dual-core processor; with four cores, a quad-core; six cores, hexa-core; eight cores, octa-core. ... When referring to types of processors, the Intel Core, code-named Yonah

3. RAM

   • why
   • what
     • Random access memory, or RAM, is one of the most important components of not only desktop PCs, but laptops, tablets, smartphones, and gaming consoles. ... Perhaps the best analogy for what RAM is to think of it as like your system’s short-term memory
