A computer is an electronic device that stores and processes data. A computer includes both hardware and software.
In general, hardware comprises the visible, physical elements of the computer, and software provides the invisible instructions that control the hardware and make it perform specific tasks.
A computer consists of: CPU, memory, storage devices (such as disks and CDs), input devices (such as the mouse and keyboard), output devices (such as monitors and printers), and communication devices (such as modems and network interface cards).
A computer’s components are interconnected by a subsystem called a bus.
You can think of a bus as a sort of system of roads running among the computer’s components; data and power travel along the bus from one part of the computer to another .
In personal computers, the bus is built into the computer’s motherboard, which is a circuit case that connects all of the parts of a computer together.
A Computer consists of: CPU, Memory, Storage Devices, Input Devices, Output Devices, Communication Devices.
