In computing and computer science, a processor or processing unit is an electrical component (digital circuit) that performs operations on an external data source, ...
A modern consumer CPU made by Intel: An Intel Core i9-14900KF Inside a central processing unit: The integrated circuit of Intel's Xeon 3060, first manufactured in 2006. A central processing unit (CPU), also called a central processor, main processor, or just processor, is the most important processor in a given computer.
A microprocessor is a computer processor for which the data processing logic and control is included on a single integrated circuit (IC), or a small number of ICs. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit (CPU).
At least one CPU (central processing unit), which performs most of the calculations that enable a computer to function. [49] It can be informally referred to as the brain of the computer. [ 50 ] It takes program instructions from random-access memory (RAM), interprets and processes them and then sends back results so that the relevant ...
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
Processor (computing) Central processing unit (CPU), the hardware within a computer that executes a program Microprocessor, a central processing unit contained on a single integrated circuit (IC) Application-specific instruction set processor (ASIP), a component used in system-on-a-chip design
At first, more than one program ran on a single processor, as a result of underlying uniprocessor computer architecture, and they shared scarce and limited hardware resources; consequently, the concurrency was of a serial nature. On later systems with multiple processors, multiple programs may run concurrently in parallel.
Front-end processor is also used in a more general sense in asymmetric multi-processor systems. The FEP is a processing device (usually a computer) which is closer to the input source than is the main processor. It performs some task such as telemetry control, data collection, reduction of raw sensor data, analysis of keyboard input, etc.
