Storage Devices
HDD (Hard Disk Drive) – A HDD is used in most standard PCs (Personal Computers) as a form of data
storage that stores data by spinning a set of magnetised discs around extremely fast with a needle
hovering above it to send transmissions interpreted as data.
SSD (Solid State Drive) –A SDD is a storage device that operates in a similar fashion to RAM (Random
Access Memory) but instead the data is allowed to be permanently stored.
Pen Drive - A Pen Drive is a small USB device that can be plugged in to a user’s computer to store
small amounts of data on it.
External HDD – An External HDD is essentially just an internal HDD; however it can be used in the
same way a Pen Drive can.
CD/DVD/Blu-Ray – These discs allow transfer of data between itself and the device that is currently
reading it by projecting lasers off of the bottom surface of the disc.
Memory Cards – Memory cards are typically used on digital cameras to store images and videos on.
SD cards are usually used to transfer stored data between digital cameras and computers.
Input Devices:
Mouse – A USB mouse is connected to the computer through a USB port and is used to
control and manipulate the on-screen mouse and GUI (Graphical User Interface) Operating
System.
Keyboard – A USB keyboard is connected to the computer through the USB port and is used
to add letters and numbers to any suitable file formats on computers.
Microphone – A Microphone allows a user to speak in to the device or record sounds to
input those sounds on the computer.
Webcam – This device allows users to record and stream whatever footage is currently being
shown through the camera on their device.
Scanner – The scanner lets users place a physical document in to the scanner and have it
generated in to a digital picture format which is then saved on the computer.
Graphics Tablet – This device allows users to use a stylus to manipulate an art program by
drawing lines.
Controller – A controller will allow you to more fluently interact with some features of a
computer remotely, such as opening the disk drive or playing an audio file.
Mobile Phone – A mobile phone can connect to the computer to download and upload files
between the two devices.
Camera – A digital camera will allow the user to connect to the computer and upload any
images or videos it has captured.
Output Devices:
Monitor – A monitor will display the information the computer is processing, usually this will
be a GUI Operating System like Windows 7.
Speakers – A speaker will project any supported digital audio formats as sound waves.
