The document discusses various types of internet connections including analogue/dial-up, cable, satellite, DSL, and Internet2. Analogue/dial-up is the slowest and uses a modem to connect via phone lines. Cable uses coaxial cables for faster transmission than phone lines. Satellite provides connectivity anywhere but is slower than broadband due to distance. DSL uses phone lines for an always-on connection and comes in varieties like ADSL. Internet2 has extremely high speeds up to 100Gbps but is uncommon.
