Difference between protocol and standards
Protocol A protocol is a particular set of rules for having a conversation between two computers to convey a specific set of information. It is an agreement between the communicating parties on how the communication is to proceed. Violating the protocol will make the communication more difficult. An example of protocol would be TCP/IP. The specifics of the above […]
Lecture-2: Network and Protocol Architecture
Objective: i. To learn about Network Architecture ii. To introduce the concepts of OSI and the service primitives iii. To introduce a simple client and server interaction on a connection oriented network Network: A network is an interconnection of a set of devices capable of communicating using well defined set of rules called protocol. Network […]

Components of a computer communication
Components of a computer communication To communicate, we need at least two parties one known as the sender and another who will listen or technically called as receiver. Even when we human talk face-to-face to each other our voice travels through air before it strikes the listener’s ear diaphragms. Well, this is not all […]
Characteristics of Data Communication and Data Representation
Characteristics of Data Communication The effectiveness of a data communications system depends on following four fundamental characteristics. I. Delivery :- The system must deliver data to the correct destination. Data must be received by the intended device or user and only by that device or user. For this purpose the destination address must be assigned for […]
