A CPU is the brain of a computer, according to About.com's Tim Fisher. Short for "central processing unit," the CPU interprets commands before executing them. The CPU is also called a processor or central processor.Know More
A CPU uses complex algorithms and programming to interpret signals and code. Many computer processors feature multiple cores, which help them process information more efficiently and quickly. A CPU retrieves information from the code within programs. It reads it to understand what the code is for, and then it executes the instructions.
A CPU is a small, square, internal piece of a computer that sits on the motherboard in a specialized slot made to hold a certain style or model of central processor. Many CPUs are connected to the motherboard with clamps and pins that are easily damaged. Since a CPU is the main component that processes data, it gets very hot as it works and needs a heatsink and fan to prevent damage, according to Fisher. Alternatively, some computers use water cooling systems.
The two most popular CPU brands are AMD and Intel, and these processors are found in a variety of electronics, including phones, laptops, desktops and gaming consoles. Processor speeds are measured in megahertz and gigahertz.Learn more about Computers & Hardware
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.Full Answer >
CPU registers perform a variety of functions, a primary one of which is to offer temporary storage for the CPU to access information stored on the hard drive. Every CPU register has a distinct function and the registers are essential components of CPU commonly recognized for memory allocation purposes.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 >
