What is CPU?
NO , its not the big box from which wires come to your Monitor/display device (by the way that big box is known as cabinet) Now, A CPU i.e. Central Processing Unit is like the brain of your computer. Its when you open your cabinet , the CPU is a square chip under the large fan on your motherboard. Imagine you haing two brains, And now think of the benifits .. Generally till date everyone had single core processor. Dual core processors are now taking plac of single core. What are dual core processors? A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It’s the equivalent of getting two microprocessors in one. In a single-core or traditional processor the CPU is fed strings of instructions it must order, execute, then selectively store in its cache for quick retrieval. When data outside the cache is required, it is retrieved through the system bus from random access memory (RAM) or from storage devices. Accessing these slows down performance
Abbreviation of central processing unit, and pronounced as separate letters. The CPU is the brains of the computer. Sometimes referred to simply as the processor or central processor, the CPU is where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system. On large machines, CPUs require one or more printed circuit boards. On personal computers and small workstations, the CPU is housed in a single chip called a microprocessor. Two typical components of a CPU are: The arithmetic logic unit (ALU), which performs arithmetic and logical operations. The control unit, which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
