Difference between Transport Layer and Network Layer

The network layer and transport layer are two of the seven layers of the OSI model. The network layer is the third layer of the OSI model which provides communication between hosts of different networks. The transport layer is the fourth layer of the OSI model which is responsible for the process to process delivery of ...

Stop and Wait Protocol

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 ...

Digital Signature in Computer Network

Digital signatures allow us to verify the author, date, and time of signatures and authenticate the message contents. To verify the integrity and validity of digital messages and documents, it employs a cutting-edge mathematical technique. It helps us combat the issue of impersonation and tampering in digital communications and ensures that the contents of a message are ...

TCP/IP Protocol Suite

TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols that makes data exchange between two devices possible. TCP/IP specifies how data should be packetized, addressed, transmitted, routed, and received on a network by providing end-to-end communication. As compared to the OSI model, which is a theoretical model, TCP/IP is an application and practical ...

MQTT Protocol

MQTT stands for Message Queuing Telemetry Transport and is a lightweight publish/subscribe messaging protocol for Machine to Machine(M2M) telemetry in low bandwidth environments. It was developed in 1999 by Arlen Nipper and Andy Stanford-Clark of IBM to link Oil Pipeline telemetry systems through satellite. It was once a proprietary protocol, but in 2010 MQTT was made available royalty-free, and in 2014 MQTT was made an OASIS standard. MQTT ...

Integrated Services Digital Network (ISDN)

Integrated Services Digital Network (ISDN) comprises communication standards facilitating the concurrent digital transmission of voice, video, and data over traditional public switched telephone network circuits. Unlike its predecessor, which primarily transmitted voice, ISDN’s innovation lies in integrating speech and data on the same lines, a capability absent in traditional telephone systems. Operating as a circuit-switched ...

How Does the Internet Work?

An internet is a huge network of networks that helps us to connect millions of computers together. These computers that are connected to each other through the internet can interact with each other over the internet. The Internet operates on a technique called packet switching. In packet switching, the data that is transferred among the different computers ...
