Connecting Devices

1. Wired

   • USB Cabled
     • To connect a variety of peripheral devices to other devices
       • Peripherals are devices such as printers and scanners that are attached to a computer system but are not actually part of it.
   • Ethernet Cables
     • To connect devices to the internet via the telephone socket
   • HDMI Cables
     • Can be used to connect all the components of your home entertainment system, regardless of manufacturer.

2. Wireless

   • Bluetooth
     • connects devices wirelessly over a short distance.
       • Devices using Bluetooth® have to be ‘paired’ using the same passcode, which helps keeps data safe when it is being transferred.
   • Wi-Fi
     • Requires connection to a wireless route
       • Wireless networks are less secure than wired networks, so data is usually encrypted for transmission over the network.
         • There are several types of encryption used on wireless networks: WEP, WPA, WPA2, AES. All of these are used to make data more secure
   • Infrared
     • The devices need to be close to each other, making the transfer of data quite safe and not interfering with other devices.
