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 […]

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 […]
