5. Dial-Up Internet Dial up internet is an extremely slow internet connection. 56kbps (roughly 0.5mpbs). Requires a phone-line and a modem on your computer. Dial’s your ISP to make a connection. Charges per minute (often around 1p per minute). Not suitable for downloading music etc (an average song would take around 1- 2 hours to download!) Perfect for rare use. Ideal for businesses when connecting simply to send an email etc.

6. Satellite Internet Useful for users where standard internet (broadband / cable) is not available. Also ideal for people who like to move around a lot. Available world-wide Some delay when using the connection, making it a bit “laggy / jumpy.” Not suitable for online games or advanced use like “remote surgery” Suffers from “rain fade.” Signal deterioration from moisture. Around 3mbps @ £30 a month.
