2.3.3 Twisted Pair
There are two types of Twisted Pair Cables, Shielded Twisted Pair (STP), and Unshielded Twisted Pair (UTP). Shielded Twisted Pair Cables have a very thin wire mesh that shield and protect the transmission. STP cables are used for the older phone networks, as well as data and network communications which are clearer and have less interference with the outside. Whereas Unshielded Twisted Pair Cables have no wire mesh and are therefore not protecting the transmission in the wiring. UTPs are mainly used for Local Area Networks (LAN) as well as telephone connections, however these are more vulnerable than STPs (Shielded Twisted Pair).

3. Backing Storage
3.1 Types 3.1.1 Disks
You can back up your storage on a separate Hard Disk and on other forms of Disks such as a Floppy Disk. Using another Hard Disk to back-up your storage is useful because it means that you can back-up everything that is stored on the Hard Disk you want to back-up. However it all depends on the size of Hard Disk you get. If it’s much smaller than your current Disk, then you will only be able to back-up the more important stuff that is stored on the Disk. Whereas if you got a Hard Disk that is bigger than your current Disk, then you will have room to back-up the whole Disk, as well as add extras when you need to back-up more recent data.
