The main function of the CPU is processing instructions given to the computer. This is why the CPU is known as the "brain" of the PC. Every operation that is carried out, including key strokes, opening and closing programs, and saving files, is carried out by the CPU. This function is separated into four functions or steps for every operation: fetch, decode, execute and store.Know More
Typically, the main parts of a CPU responsible for carrying out the operations are the arithmetical logical unit and the control unit. The ALU carries out arithmetic and logical operations and makes decisions, whereas the CU fetches, decodes and executes processes.
The most popular CPU manufacturers, as of 2014, are AMD and Intel. Initially, a CPU contained only one processor; then, Intel came up with the dual-core processor, a CPU containing two processors, also known as two cores. For over two decades, as of August 2014, both Intel and AMD have continued to develop and produce multiple core processors. These are quad core, hexa core and octo core, or four, six and eight cores, respectively.
Other characteristics for functional performance of a CPU are the clock speed and the number of instructions it can perform in a second.Learn more about Computers & Hardware
A computer's CPU is considered the "brain of the computer," being responsible for its major processes, like searching for information, sorting information, making calculations and advanced processes as well as decisions integral to the functioning of the computer. The acronym CPU actually stands for central processing unit and, as such, works behind virtually any task the user is doing on their computer, like writing essays, making photo albums or reading emails. The CPU is made out of a very complex silicon integrated circuit board mounted with tiny, microscopic transistors that can easily number in the billions.Full Answer >
The three major components of a CPU are the arithmetic logic unit, the control unit and the cache. These components are integrated together as a single microprocessor that is mounted on the computer's motherboard.Full Answer >
A Central Processing Unit, or CPU, is the piece of hardware in a computer that carries out computer programs by performing arithmetical and logical operations. The CPU of a modern computer is contained on a single chip called a microprocessor. Some computers have more than one CPU, a development known as microprocessing.Full Answer >
A CPU register is a high-speed storage area in the CPU that represents all data prior to processing. Registers inside a CPU are also related to the amount of bits that it has. Bit size is a variable that helps determine a CPU's power and speed.Full Answer >
