motthe herboard is the most essential part of a computer system it connects

all the parts of a computer together both internal and external components of

the computer uses various slots and ports microprocessor’s central

processing unit cpu microprocessor heart of the computer is an electronic component

That controls all functions of a computer system.

It is located inside the computer case on the motherboard

It is a single integrated chip ic containing billions of very small components including transistors resistors and

diodes that work together the microprocessor functions as an artificial brain

all the arithmetical and logical functions are done by its random access memory ram

Is a computer’s primary memory it is a very fast solid-state storage medium

That is directly accessible by the CPU any open programs or files on a computer are temporarily stored in the ram


Examples of output devices (monitor, printer, speakers, etc.)

whilst being used being volatile any data storedthe  in ram will be lost when power is lost read only memory

rom is a type of primary storage medium that permanently stores data on

pcs and other electronic devices it contains the programming needed to start a pc
