1. Key terms

   • Network – A group of computers which are connected together by communication channels and which have the capability of sending and/or receiving information between them.
   • Protocol – Communications protocol is a set of rules which allows a computer system to connect with a different system to transfer data.
   • Ethernet – An Ethernet cable is used to connect a user to a network.
   • Bandwidth – Is a way of measuring how much data can be carried over a network.
   • Bit – Is the amount of data transferred within a unit of time (i.e. bits per second).

2. Bandwidth is a measure of the available capacity of a network (to carry data) measured in bits per second

3. The transmission rate is a measure of the number of pieces of information that have been transferred during a specific time period, usually also measured in bits per second. A high bandwidth means more information can be carried in a given time, so a higher transmission rate is achieved. Insufficient bandwidth can result in websites and servers appearing to run very slowly
