A protocol defines what is communicated, when it is communicated
Protocol elements
- Syntax
structure or format of data,meaning the order in which they are presented
-Semantic
meaning of each section of bits how is a particular pattern to be interpreted & what action is to be taken based on the interpretation
-Timings
when data should be sent & how fast it can be sent

Applications
Marketing & sales collecting - exchange & analyse data relating to customer sales such as teleshopping & online reservation
Financial services - foreign exchange & investment services and electronic fund transfer
Manufacturing - manufacturing processing CAD/CAM
Electronic Messaging- e-mail
Directory services - worldwide search operations
Information services - bulletin boards & data banks
EDI -allow bussiness information to be transferred without using paper

Network Criteria
Factors affecting network performance
to be considered if network to be effective and efficient
PERFORMANCE
CAN BE MEASURED AS TRANSIT TIME & RESPONSE TIME
depends on 4 characteristics
No of Users - user = 1/response time
Transmission medium- medium define the speed at which data travel through connection
Hardware - effect both speed & capacity
Software - well design s/w can speed up the process

NETWORK
Set of devices connected by media link
nodes can be a computer,printer or any device capable of sending and / or receiving data generated by other nodes on the network
links connecting often called communication channels

Basic Elements or Component
the message is the information (data) to be communicated consist of text, number, sound or video
The Sender sends a Message over the Medium to the Receiver.
Eg. Workstataion ,PC , tel. Handset, or video camera
The receiver is the device that receive the data or message
The medium for communication is very important because without the medium there cannot be any communication, and further, the nature of the medium determines the speed of communications.
Protocol set of rules that govern data communication
