A telecommunications network is a collection of nodes linked together by telecommunications links that allow the nodes to exchange messages. The links may employ several technologies to transmit messages and signals based on circuit switching, message switching, or packet switching approaches. The public switched telephone network (PSTN), the Internet, computer networks, and wireless radio networks ...
The Native VLAN functions as a conduit for untagged data across a trunk port. If untagged data arrives at a trunk port, the switch inherently assigns it to the native VLAN. The Native VLAN refers to the default VLAN for an Ethernet trunk (a link or port that carries traffic for multiple VLANs) when no ...
Circuit switching is a connection-oriented service that sends and receives data via a dedicated path. In circuit switching, it is necessary to establish an end-to-end path before delivering any data from the source to the destination. Due to the dedicated circuit path, circuit switching has the lowest probability of data loss. Still, a lot of ...
Internetworking is defined as a way to connect multiple forms of computer networks. A computer network is defined as the interconnection of two or more computers. Computer internetworking occurs when several computer LANs, WANs, or parts of a computer network are linked together using devices such as routers and coordinated through a logical addressing system ...
An IP address is a numeric identifier assigned to a computer within a network that uses the Internet Protocol for communication. This address uniquely identifies a host or a network interface and enables targeted communication to a particular destination. The ISP (Internet Service Provider) assigns an IP address, which is the logical identifier for a ...
IP routing, or Internet Protocol routing, is the process of determining the optimal path for data packets to travel from the source to their destination over an IP-based network. This network could be a local network or the worldwide Internet. IP routing involves using routing algorithms and protocols to decide how to forward data packets ...
Multicasting is a method of communication that allows data to be sent to more than one destination simultaneously. It is commonly used for applications such as video conferencing, online gaming, and live streaming. Multicast networking relies on the simple idea that a single packet can be delivered by a server and received by a large ...
Network Layer is responsible for how a machine in a network can communicate with a machine in a different network. The primary goal of this layer is to deliver packets from a source to a destination. The network layer splits data into fragments(data packets) and sends these fragments, which are then combined once the processing ...
Voice over Internet Protocol(VoIP) is a way of transmitting voice and multimedia over a network. VoIP enables users to place voice calls via their computer, smartphone, other mobile devices, dedicated VoIP phones, and WebRTC-capable browsers. VoIP is a technology that benefits consumers and businesses because it typically includes features not available on traditional phone services. ...
Message Switching is a connectionless network switching approach in which the complete message is routed from the sender node to the receiver node one hop at a time. It was a forerunner to packet switching. Message switching served as an adequate replacement for circuit switching before the development of packet switching. The first applications of ...
