- Transmission Medium
- Receiver
- Destination
What is a Protocol?
A protocol is a set of rules that governs the transfer of data between computers. It defines how the information is transmitted and how the errors are detected.
What are the 3 ‘Network Topologies’?
- Bus Topology
- Star Topology
- Ring Topology
What is Handshaking?
Handshaking is the sending of signals to indicate the type of protocol to be used for an agreement to be reached.
Why is handshaking essential?
Handshaking is essential as modems at each end of the line may have different capabilities.

What is a TCP / IP and how does it work?
Transmission Control Protocol and Internet Protocols are a common set of rules for data transmission and error detection across the internet. It works by breaking information into smaller packets of data.
What is a Fibre Distributed Data Interface (FDDI)?
A protocol that specifies computer input/output interface standards using fibre-optic cables.
What type of cable does a Fibre Distributed Data Interface used?
Fibre-Optic cables.
What is a Hypertext Transfer Protocol?
A protocol that enables the user to send and retrieve files using the internet. It allows access to Web pages that are based on hypertext.
