Document Summary
Hardware- is the physical components of a computer, anything that you can touch is the hardware. Hardware examples: cpu (or central processing unit, ram (or memory, storage (such as a hard disk, or a cd, output devices (such as the monitor, or printer, communication devices (such as a modem or network interface card (nic)) Input devices (such as a keyboard or mouse) Software- the computer programs that tell the hardware what to do (such as the operating system (os)) Cpu- is essentially the brain of the computer. It fetches instructions from the memory and executes them: the cpu works by sending pulses of electricity in a certain rhythm. A pulse of electricity is a 1, the lack of a pulse of electricity is a 0: every cpu has a speed in which these pulses are sent. The faster the speed of the processor, the faster the commands can be executed: the speed of the cpu is measured in hertz (hz)
