HDD Hard Drive

HDD, the hard drive is the computer's main storage device that permanently stores all data on the computer.  It is the memory that      Solid-State Disk, SSD is a drive keeps its content even when power is lost as a means of storing and accessing data. Compared to the other storage devices such as hard drives, an SSD has no moving parts, which gives it advantages such as accessing stored information faster, produces no noise, often more reliable, and takes up much less power or electricity than the traditional hard drive found in computers.  SSD is much faster than HDD. 

Touch Screens

Input and output device. A monitor or other flat surface with a sensitive panel directly on the screen that registers the touch of a finger as input. A touch screen allows a user to interact with a device without a mouse or keyboard.


Alternatively referred to as a video display terminal (VDT) and video display unit (VDU),a monitor is a video display screen and the hard shell that holds it. In its most common usage, monitor refers only to devices that contain no electronic equipment other than what is essentially needed to display and adjust the characteristics of an image.

Optical Drive

Short for Compact Disc-Read Only Memory, CD-ROM drives or optical drives are CD players inside computers that can have speeds in the range from 1x and beyond, and have the capability of playing audio CDs and computer data CDs. Below is a picture of the front and back of a standard CD-ROM drive.


Central Processing Unit. The computer CPU is responsible for handling all instructions it receives from hardware and software running on the computer. It is the brain of the computer that when a message is sent through input or output device it carries out instructions.


Random Access Memory (RAM) is a computer storage location that allows information to be stored and accessed quickly from random locations within DRAM on a memory module. Because information is accessed randomly instead of sequentially like a CD or hard drive the computer is able to access the data much faster than it would if it was only reading the hard drive. Volatile /Temporary memory, when computer is suddenly switched off the data or information is lost.

Mother boards

The motherboard is a printed circuit board that is the foundation of a computer and allows the CPU, RAM, and all other computer hardware components to function and communicate with each other.
