  CPU  A processor (CPU) is the logic circuitry that responds to and processes the basic  instructions  that drive a computer. The CPU is seen as the main and most crucial integrated circuitry ( IC ) chip in a computer, as it is responsible for interpreting most of computers commands. CPUs will perform most basic arithmetic, logic and I/O operations, as well as allocate commands for other chips and components running in a computer. The term  processor  is  used interchangeably  with the term central processing unit ( CPU ), although strictly speaking, the CPU is not the only processor in a computer. The  GPU  (graphics processing unit) is the most notable example, but the hard drive and other devices within a computer also perform some processing independently. Nevertheless, the term  processor  is generally understood to mean the CPU. Processors can be found in PCs, smartphones, tablets and othe...

  D EFINITION computer hardware Computer hardware is a collective term used to describe any of the physical components of an analog or digital computer. Computer hardware  is a collective term used to describe any of the physical components of an analog or digital computer. The term  hardware  distinguishes the tangible aspects of a computing device from software, which consists of written instructions that tell physical components what to do. Computer hardware can be categorized as having either internal or external components. Internal components include items such as the motherboard, central processing unit ( CPU ), random access memory ( RAM ), hard drive, optical drive, heat sink, power supply, transistors, chips, graphics processing unit ( GPU ), network interface card ( NIC ) and Universal Serial Bus (USB) ports. These components collectively process or store the instructions delivered by the program or operating system (OS). External components...
