   In computing and computer science, a processor or processing unit is an electrical component (digital circuit) that performs operations on an external data source, ...

3. Central processing unit - Wikipedia

   en.wikipedia.org/wiki/Central_processing_unit

   A CPU cache [71] is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core , which stores copies of the data from frequently used main memory locations .

4. Process (computing) - Wikipedia

   This would lead to processor being "idle" (unused). To keep the processor busy at all times, the execution of such a program is halted and the operating system switches the processor to run another program. To the user, it will appear that the programs run at the same time (hence the term "parallel").

5. Microprocessor - Wikipedia

   en.wikipedia.org/wiki/Microprocessor

   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).

6. Multithreading (computer architecture) - Wikipedia

   en.wikipedia.org/wiki/Multithreading_(computer...

   A process with two threads of execution, running on a single processor . In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.

7. Computing - Wikipedia

   A programmer, computer programmer, or coder is a person who writes computer software. The term computer programmer can refer to a specialist in one area of computer programming or to a generalist who writes code for many kinds of software. One who practices or professes a formal approach to programming may also be known as a programmer analyst.

8. Multiprocessing - Wikipedia

   en.wikipedia.org/wiki/Multiprocessing

   Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. [1] [2] The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them.

9. Data processing - Wikipedia

   en.wikipedia.org/wiki/Data_processing

   Computerized data processing, or electronic data processing represents a later development, with a computer used instead of several independent pieces of equipment. The Census Bureau first made limited use of electronic computers for the 1950 United States Census , using a UNIVAC I system, [ 3 ] delivered in 1952.
