Web browsers and servers each play a unique role in interacting with the internet. A web browser, such as Chrome or Firefox, is a tool that allows users to explore websites and view their content. On the other hand, a web server is a remote computer that hosts websites and distributes their content to browsers, ...
A protocol hierarchy in computer networks refers to the organization and arrangement of networking protocols in a layered structure. This layered approach helps in achieving interoperability, modularity, and ease of implementation and maintenance within complex network systems. The most well-known protocol hierarchy is the OSI (Open Systems Interconnection) model, which consists of seven layers. You ...
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 ...
Computer networks rely on various communication methods to transmit data between devices efficiently. Unicast, broadcast, and multicast are the three basic communication methods. Each method serves a specific purpose in distributing information across a network. Unicast allows two devices to communicate privately, broadcast sends data to all devices in a network segment, and multicast efficiently ...
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 ...
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 ...
