Peripherals
A Peripheral is any device that is connected to the computer but isn't actually part of the computer itself and it allows your computer to perform an extra function. They include input and output devices. Input devices are peripherals that give information to the computer, whereas the computer gives out information to the output device, such as printers.

INPUT DEVICES:
Keyboard:
A series of buttons that are used in order to create words and do other functions on the computer.
Mouse:
Used to navigate through the display screen and allows you to select items.
Scanner:
Used to input information from the hardcopy into the computer. This includes pictures and text.
Digital Cameras:
Digital cameras are now used to upload pictures onto your PC. Currently, you (the user) are able to look at pictures on the computer that have been taken and of course you have the option to delete pictures. The digital camera is an input device as the information comes in as a picture and is then transferred to your PC.
Webcams:
These are basic digital video cameras that are used to take images which are to be sent down through networks for video conferencing. However, you cannot save the photos like digital video cameras do, but are considered as input devices because they are sending data in the form of videos from the outside to the inside of the computer.
OUTPUT DEVICES:
Printers:
Printers are used to produce a hardcopy or printout. Printers are output devices because they give out information from the computer into a hardcopy.
Plotters:
A plotter produces hardcopy from the computer like a printer but in a different way. It has one or more pens that draw onto the paper. Plotters are usually used for producing very accurate plans and drawings that have been created using certain computer software.
Plotters are output devices because it sends data out of the computer through the use of paper.

Cables:
Coaxial Cable:
Coaxial Cable is a type of wire that is used for TVs and computers. In computers, it is used to connect to the network card. Coaxial cables can transfer more data so it makes the internet connection faster. The wire is surrounded by an insulation and then covered with grounded shield of braided wire which helps to minimise electrical and radio frequency interference.

Optical Fibre Cable:
The optical fibre wires are coated with plastic layers and are kept in a protective tube, made right for the environment where the cable will be put. Optical fibre cable is the fastest way of transferring data; it can transfer data up to 182,000 km/s, which makes it ideal for internet connections. They are usually used for internet connectivity because it gives the fastest internet connection at all times.

Twisted-pair cable:
The twisted-pair cable is the least expensive type of local area network (LAN) cable. Most network wires have some twisted-pair cabling somewhere along the network cable.
Twisted-Pair cable is made up of two insulated wires twisted around one another. This is useful because it reduces some types of interferences.
