Computer Hardware

This is how a computer works


A drive such as a hard drive, optical drive and solid state drive is something that is a device for storing and retrieving digital information, primarily computer data.

A optical drive is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs.

A solid state drive is a data storage device that uses integrated circuit device assemblies as memory to store data persistently such as a memory card or memory stick


A monitor is an output because it shows you what you are doing on the screen.


CPU stands for central processing unit.CPU is the hardware within a computer system which carries out the instructions of computer program by performing the basic arithmetical, logical, and input/output operations of the system


RAM stands for Random-access memory it is a form of computer data storage. A random-access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order. In contrast, other data storage media such as hard disks, CDs, DVDs and magnetic tape read and write data only in a predetermined order.


ROM stands for Read-only memory it is a class of storage medium used in computers and other electronic devices. Data stored in ROM cannot be modified, or can be modified only slowly or with difficulty, so it is mainly used to distribute firmware (software that is very closely tied to specific hardware, and unlikely to need frequent updates).


A motherboard (sometimes alternatively known as the mainboard) is a printed circuit board

(PCB) found in many modern computers which holds many of the crucial components of the system, such as the central processing unit (CPU) and memory.


In computing, input/output or I/O is the communication between an information processing system (such as a computer) and the outside world, possibly a human or another information processing system. Inputs are thye signals or data received by the system, and outputs are the signals or data sent from it. Input/Output devices are used by a person (or other system) to communicate with a computer. For instance, a keyboard or a mouse may be an input device for a computer, while monitors and printers are considered output devices for a computer. Devices for communication between computers.

Touch Screens

A touch screen is a device which you control with either your hand, finger or a stylus which detects your touch in the touch display area.

Touch screens are common devices in game consoles, smartphones and tablet computers such as an Ipad
