Virtual points where network connections begin and stop are called ports. Ports are software-based and controlled by operating system. Each port is connected to a different procedure or service. Ports allow computers to easily differentiate between different kinds of traffic: emails go to a different port number than webpages, for example, even though both reach ...
Sockets in computer networks are used for allowing the transmission of information between two processes of the same machines or different machines in the network. The socket is the combination of IP address and software port number used for communication between multiple processes. Socket helps to recognize the address of the application to which data is to be sent using ...
We are here with one of the techniques used in data transmission for detecting an error. The name of that error detection algorithm is Checksum. It is essential to perform error detection in data transmission. The Checksum is an error detection technique that detects an error in a transmitted message by appending redundant bits in the message. So this ...
To maintain the rate of data transmission between sender and receiver, it is required to use flow control protocol. The data link layer provides us with the protocol for controlling the data transmission rate. So here we are going to discuss one of the flow control protocols named stop and wait protocol. The stop-and-wait protocol ...
