CompTIA A+ 1101 Internet Connection Types

Satellite Networking

- uses a satellite dish to communicate with a satellite in low earth orbit

- non-terrestrial communication (high cost)

- common speeds of 50 megabits per second, down, and 3 megabits per second, up

- high latency

- high frequencies

- operates over line of site

Fiber Networking

- high speed data communication

- higher installation cost than copper

- allows for communication over long distances

Cable Broadband Networking

- uses a cable television cable

- use data, voice, and video over the same connection

- supports high-speed networking

- common speeds of 50 megabits per second through 1000+ megabits per second

- broadband (can send multiple streams of data across a single wire by communicating across multiple frequencies on that wire)

DSL (Digital Subscriber Line) Networking

- in most cases, ADSL (Asymmetric DSL)

- common speeds of 200 megabits downstream, and 20 megabits per second upstream

- about a 1000 foot limitation from the central office

- uses telephone lines

WISP (Wireless Internet Service Provider) Networking

- terrestrial internet using wireless

- speeds can range from about 10 megabits per second to 1000 megabits per second
