The Components of Hardware

Computer is an electronic device to enter, to process and to show data. Computer has some parts. One part of computer is hardware. Hardware is the physical device of the computer that can be seen. Hardware has five components.

    First component of hardware is CPU (Central Processing Unit). CPU is the brain of a computer. CPU has two components, there are control unit and logic unit. The control unit controls and coordinates the actions of the other components. The logic unit performs numeric operations and logical operations.

    Second component is input and output device. Input and output devices is to help user communicate with the computer.  The input devices consist of keyboards and mouse. The output devices consist of  monitors and printers.

    Third component is memory. Memory stores data and program instructions for the CPU to execute. 

    Fourth component is storages device. There are four main types of storage devices. The main types of storages device is Disk drives (hard disks and floppy disks), CD drives (CD-R, CD-RW, and DVD), Tape drives and USB flash drives.

    The last component of hardware is communication devices. Computers can be networked through communication devices. The components of communication devices are the dialup modem, DSL, cable modem, and network interface card.

    So, hardware has five components. The components of  hardware consists of CPU (Central Processing Unit), input and output device, memory, storages device, and communication devices.
