Tuesday, June 21, 2011. To store data locally in order to speed up subsequent retrievals. Reserved areas of memory in every computer that are used to speed up instruction execution, data retrieval and data updating. Pronounced "cash," they serve as staging areas, and their contents are constantly changing. There are two kinds: memory caches and disk caches. A computer has solid state and non-solid state parts. The solid state components are the motherboard, chips, screen, camera and optical mouse, wh...

Tuesday, May 24, 2011. It is a type of computer memory that provides direct access to any single location (any byte). RAM chips are "byte addressable." The contents of any byte can be read or written without regard to the bytes before or after it. The term generally refers to main memory, which is the computer's workspace, and the most common type of RAM is the DRAM chip. RAM read and write speeds are generally the same, taking no longer to write a byte than it does to read one. Graphics cards are PCBs (...
