| Question | Answer |
| Wired Ethernet | The wired Ethernet cable is used for connecting devices to a network using fast and secure wires. Fast and secure. Because there are wires, the range is limited. Which also means that it is difficult to expand and less mobile. This method is also more expensive than using a wireless network. The wired method is also not very convenient and the user can’t move around. Furthermore, it is quite difficult to set-up. Wired, fast, limited range, expensive difficult to setup. |
| Wi-Fi (wireless) | Wi-Fi is a computer network that can link devices in a building or group. Wi-Fi networks are limited to a single building or a few buildings. However, one Wi-Fi network can be connected to other Wi-Fi networks over any distances by telephone lines and radio waves. Easy to setup, no cables connected to computer, can connect to LAN anywhere in limited range, expanding a wireless network is much cheaper and less complicated compared to a wired network, more mobile, better range. can be interference with the signal, less secure, slower than a wired LAN. Wireless, easy to setup, you can connect anywhere in limited range, expanding is cheap, good range, can have interferences, slower compared to a wired network and less secure. |
| Bluetooth | Bluetooth is a standard for the short-range wireless interconnection of mobile phones, computers, and other electronic devices. One advantage of Bluetooth working within a short range is that it only needs a tiny amount of radio power to work. This means it is ideal for battery operated devices such as mobile phones. One disadvantage of using Bluetooth internet is that the connection can sometimes run very slow so Bluetooth internet is not highly suggested for all cases. Slow, up to 100m range, free, reliable and quite secure. |
| GPRS | GPRS (General Packet Radio Service) is a packet oriented mobile data service on the 2G and 3G cellular communication system's global system for mobile communications. GPRS-enabled mobile phones to use the Internet where Internet access is not readily available but a mobile network is. Another advantage of GPRS is that it is portable connection and a backup option for the Internet. GPRS is usually billed per megabyte or kilobyte, depending on the individual service provider. However, this has changed in many places, where GPRS downloads are no longer charged as per usage, but are unlimited, and there is merely a flat fee to be paid every month. Generally slow but reliable and not very secure. |
