It performs programmed computation with great accuracy & higher speed. Or in other words, the computer takes data as input and stores the data/instructions in the memory (use them when required). It then processes the data and converts it into useful information. Finally, it gives the output. Here, input refers to the raw data that we want the machine to process and return to us as a result, output refers to the response that the machine provides in response to the raw data entered and the processing of data may involve analyzing, searching, distributing, storing data, etc. Thus, we can also call a computer data processing system. Similar is the function of computer memory, and it has similarities with the human brain. But oversimplification in this regard will be hazardous because the human brain is a very complicated and sophisticated piece of machinery. It has memory and processing, entwined together, along with the capability for feelings and emotions which a computer system lacks. Working memory serves as an intermediate, for understating and retrieving for the brain to process information. Information in the form of stimuli is encoded following explicit or implicit functions by the working memory processor. The working memory also retrieves information from previously stored material. The book tells you everything you need to know about the logical design and operation, physical design and operation, performance characteristics and resulting design trade-offs, and the energy consumption of modern memory hierarchies"-- Back cover.
