Virtual – circuit network is a category of packet switching network, where a virtual path is established between the source and the destination systems for data communication to occur. This path appears to the user as if it is a dedicated physical path, but actually is a logical circuit allocated from a managed pool of circuit resources as per traffic requirements. The network resources forming parts of this path can be shared by other communications, however, is not visible to this user.Features of Virtual – Circuit NetworkVirtual – circuit switching is done at the network layer of the communication system.In ...

Carrier Sense Multiple Access (CSMA) is a network protocol for carriertransmission that operates in the Medium Access Control (MAC) layer. It senses or listens whether the shared channel for transmission is busy or not, and transmits if the channel is not busy. Using CMSA protocols, more than one users or nodes send and receive data through a shared medium that may be a single cable or optical fiber connecting multiple nodes, or a portion of the wireless spectrum.Working PrincipleWhen a station has frames to transmit, it attempts to detect presence of the carrier signal from the other nodes connected to ...

What is Topology?Network Topology is the way network links and nodes are connected with each other. The physical signal transmission medium is referred to as network topology. On the other hand, "logical network topology" refers to how the data flows through a network among the connected devices, regardless of their physical link.In this article, we will compare and contrast the different features of two network topologies: Star Topology and Ring Topology. Read through this article to find out how Star Topology differs from Ring Topology.What is Star Topology?In a Start topology, a piece of a network is connected to a ... Read More

SMTP and POP3 are message protocols which are required for sending and receiving the messages between the mail servers. In this article, we are going to compare and contrast the various features of SMTP and POP3 based on the tasks for which these two protocols have been designed. What is SMTP? The Simple Mail Transfer Protocol (SMTP) is an Internet communication protocol for sending and receiving electronic mail. SMTP is used to transmit and receive mail messages by mail servers and other message transfer agents. User-level email clients usually utilize SMTP exclusively to transmit messages to a mail server for ... Read More

In communication systems, the data transfer between a sender and a receiver follows a particular mode which is also known as the "transmission mode". On the basis of the nature of data sent and received, we can categorize the Transmission modes as Simplex, Half−duplex, and Full−duplex. Read this article to find out more about these transmission modes and what sets them apart. Simplex Mode of Data Transmission In a data communication network, when there is a single movement of data or one control movement of data from the sender to the receiver, then it is called the Simplex mode of ...

Both Client-Server and Peer-to-Peer networks transfer data from a source to a destination with minimal loss in transmission. Both these networks establish a communication channel through which data transmission takes place, however the channel remains dedicated in case of a Client-Server network, which is not the case with Peer-to-Peer networks.Read through this article to find out how client-server networks differ from peer-to-peer networks.What is a Client-Server Network?The client-server paradigm is a network process communication structure that connects service requestors, clients, and providers. A network or the Internet is used to connect the client and the server.The client-server approach, which also ... Read More

Communication, in general, is the process of transferring data from a source to a destination by using any of the available modes such as audio, video, text or even signals, etc. This communication may be straightforward between one sender and one receiver or it may include multiple senders and receivers. On the basis of the number of senders and receivers involved, a communication can either be "Point-to-Point" or "Multi-point".Read through this article to find out more about these two forms of communication and how they differ from each other.What is Point-to-Point Communication?In telecommunications, a point-to-point connection is a communications link ...

What is Routing? The process of determining a path for traffic inside a network or across or across different networks is known as routing. Routing occurs in a wide range of networks, including circuit-switched networks like the public switched telephone network (PSTN) and computer networks like the Internet. Routing is the higher-level decision-making in packet switching networks that sends network packets from their source to their destination through intermediate network nodes using particular packet forwarding techniques. The passage of network packets from one network interface to another is known as packet forwarding. Routers, gateways, and other network hardware devices are ... Read More
