The Simplest Guide For Computer Hardware!!!


Its is known as a Hard Disk Drive and abbreviated as HD or HDD. A Hardrive is a data storage device that allows you to save data on your computer. The Hardrive was introduced on September 13, 1956 and consists of one or more Hardrive platters inside of air sealed casing.  Most computer hard drives are in a internal drive bay at the front of the computer and connect to the motherboard using either ATA, SCSI, or a SATA cable and power cable.

Optical Drive

An optical drive is a type of computer disk drive that reads and writes data from optical disks through laser beaming technology. This type of drive allows a user to retrieve, edit and delete the content from optical disks such as CDs, DVDs and Blu-ray disks. Optical drives are among the most common computer components .An optical drive may also be known as an optical disk drive (ODD).


The term "monitor" is often used with "computer screen" or "display." The monitor displays the computer's user interface and open programs, allowing the user to interact with the computer, typically using the keyboard and mouse. Older computer monitors were built using cathode ray tubes (CTRs), which made them rather heavy and caused them to take up a lot of desk space. Most modern monitors are built using LCD technology and are commonly referred to as flat screen displays.


Whenever you enter data into your computer, it is referred to as input. This can be text typed in a word processing document, keywords entered in a search engine's search box, or data entered into a spreadsheet. Input can be something as simple as moving the mouse or clicking the mouse button or it can be as complex as scanning a document or downloading photos from a digital camera.

Output Devices

Any device that outputs information from a computer is called, not surprisingly, an output device. Since most information from a computer is output in either a visual or auditory format, the most common output devices are the monitor and speakers. These two devices provide instant feedback to the user's input, such as displaying characters as they are typed or playing a song selected from a playlist.

Touch Screens

A touchscreen is a display that also serves as an input devices. Some touchscreens require a proprietary pen for input, though most modern touchscreens detect human touch. Since touchscreen devices accept input directly through the screen, they do not require external input devices, such as mice and keyboard. This makes touchscreens ideal for computer kiosks, as well as portable devices, such as tablets and smartphones.
