Hardware Computer Hardware and peripherals Hardware in general consists of the electronic components, boards, peripherals, and equipment that make up a computer system.
Computer hardware is a collection of switches.
These switches manipulate the flow of electricity. Most of the switches here are permanently locked into position. All the switches and the circuitry in a computer are designed either to store the information that the CPU needs, transport it to and from CPU, or respond in some way to the CPU's output. The number of instructions a CPU chip can have is related to the number of bits it can handle at one time. Computers work with binary numbers, and bit is the basic unit of information in a binary numbering system.
