Network Protocols and Addressing
Terms in this set (4)
A MAC address is a unique number written into the network card, composed of six pairs of hexadecimal characters
A protocol is an agreed upon format for transmitting data between devices. A good protocol should define: how to set up and stop a connection, how to start and end a message, how to deal with corrupted data and how to format the data.
In networking, data is broken up into independent packets containing a certain amount of bits. It is up to the network designer to decide the size of each packet, typically they start from 512 bits upwards. These packets travel through the network and get re-assembled in the right order on the receiving computer. Splitting the data into packets makes data transmission very reliable. If a packet is missing, then the receiving computer asks for that one to be re-sent.
A host name is a human-readable label that is assigned to a network device
