Input Devices
-Scanner accepts picture data. It's basically just a camera specialised for paper. It turns hard copy data into soft copy information.
-Keyboard lets you enter text when you type.
-Mouse lets you enter commands whenever you click, hover or drag. You can also use it to control what you view on your monitor by scrolling.
- Cameras let you capture data in the form of pictures.
Output Devices
-Monitor or Visual Display Unit (VDU) lets you interact with your computer by giving you processed soft copy information to view straight from your computer.
-Printer turns soft copy into hard copy information in the form of ink on paper.
-Plotters are basically the same as printers except for the fact that they give way more detailed pictures because they draw with a special pen built inside of them.
-Projectors are basically monitors that allow many people to see at a time. They show you anything you can see on your monitor on a background.
Storage Devices
-Flash drives are highly portable and have small information capacities ranging from 2 - 128 gigabytes.
-Hard Drives are less portable and are sometimes built into the computer but they can take up to a few terabytes of data (which is a lot).
-Compact Disks CDs require a special type of drive to access the information in them. Their capacity depends on the number of tracks they have at the centre. Some are read-only while others can be written.
-Solid State Drives are a specialised typeof hard drive that are designed to operate faster than a normal hard drive, allowing applications to loaf almost instantly.
