What is a cpu
it's the abbreviation for central processing unit. The C.P.U. is called the brains of the computer. Occasionally referred to only as the central processor, but some usually named processor, the C.P.U. is where most calculations take place. In terms of computing power, the C.P.U. is the most crucial component of a computer system. With big machines, CPUs need single or a few printed boards. With microcomputers and little workstations, the processor is put up in a individual chip named a microprocessor. For the 1970's the microprocessor class of CPUs has almost totally overtaken all other CPU implementations. The C.P.U. itself is an internal element of the computer. Modern C.P.Us is little and foursquare and contain multiple metallic connecters or pins on the bottom. The C.P.U. is put in straight into a C.P.U. socket, pin side down, with the CPU board. For each one CPU board will support simply a particular type or range from C.P.U. Then you have to look into the CPU board producer specs before trying to substitute or raise a C.P.U.. Modern processors as well have a connected on a heat sink and small fan that go straight with upside from the C.P.U. to assist over heat.
What is cpu
can Fetching a command ?
The CPU fetches its commands from the memory board*. The memory board might live in RAM (Random Access Memory) into which it must have been initially loaded from other device, such as a hard disk. The CPU. maintains a counter internally of which command is to be fetched the next time an command is quested. These counter is known as the Instruction Pointer (IP). Once an instruction has been fetched, the IP is moved forward in memory to point to the next instruction to be fetched.
And Finaly what is cpu
the major brands?. they are 2 major brand, Intel and AMD provide us a wide range of CPUs and the two companies' products are in direct competition. AMD and Intel CPUs are able of running the same PC software and are not software specific or proprietary in nature.
2 characteristic elements of a C.P.U. are the following:
1. The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
2. The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
