A linked list is a dynamic data structure comprised of nodes, each containing data and a pointer to the next node. Unlike arrays, linked lists don’t require contiguous memory, making them ideal for dynamic resizing. The initial node, known as the HEAD, serves as the starting point for traversal. Comparatively, while arrays have fixed sizes, ...
Robert Metcalfe and others developed the Ethernet protocol at Xerox PARC in 1973 as a wired communication protocol that links computers over a network. This is a widely used LAN protocol, also called Alto Aloha Network. A wide area network and an original area network are connected by it. What is Ethernet? Ethernet in computer networks refers ...
Essential for connecting devices to broader networks, access networks underpin services like Internet, VoIP, and video streaming. Blending wired and wireless technologies is vital for personal and enterprise use. Maintained by ISPs, these networks continuously evolve, incorporating technologies like FTTH to enhance speed and reliability. What Does an Access Network Do? Before the employment of ...
In a computer, when the data packet is transmitted from one network to another network, it is required to choose the best path for transmitting the packet. Hence, routing is the concept of the network layer of the OSI suite, which selects the best path for transmitting packets among the network. The router is a ...
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 ...
Until the introduction of software-defined networking (SDN), a class of technologies that separates the network control plane from the forwarding plane to enable more automated provisioning and policy-based administration of network resources, hardware ruled the networking industry. The most accurate definition of SDN is the technology that separates the management of network devices’ control planes from the underlying data ...
In OSI suite, there are 7 layers and all layers provide different services. Today we are here with detailed information on one of the layers i.e. transport layer which provides process-to-process communication in OSI suite. Transport Layer in Computer Networks is an end-to-end layer that is used to deliver messages to a host. In OSI model, the transport layer ...
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 ...
SMTP (Simple Mail Transfer Protocol) protocol is the standard mechanism for “sending and receiving the electronic mails via the internet”. SMTP is a set of guidelines that enables users to exchange information. The actual mail transfer is carried out through the message transfer agent i.e. a system should have the client MTA(Mail Transfer Agent) to send mail and it should ...
TCP establishes a secure and reliable connection between two devices. This is possible because of the TCP’s 3-way handshake process, which occurs when two devices establish and close connections. There are three steps to both establishing and closing the connection, as the name implies. So, in this article, we’ll go through the TCP 3-way handshake process ...
