Network layer 2 devices. ). Two basic network types are local area networks (LANs) and wide area networks (WANs). When frames arrive at the layer 2 device, it looks for the destination MAC Address and makes a forwarding decision accordingly. Discover how a computer network works, and explore the different network types and topologies. How to use network in a sentence. Layer 2 devices are the devices that transmit the frame with the help of MAC Address, also called physical address. Jun 25, 2025 · A network is a collection of computers, servers, mainframes, peripherals, or other devices connected to facilitate communication and data sharing. Devices used in each layer are…. The meaning of NETWORK is a fabric or structure of cords or wires that cross at regular intervals and are knotted or secured at the crossings. It conceptually divides computer network architecture into 7 layers in a logical progression. Jul 5, 2023 · In a computer network, we have different networking devices working at different layers. Sep 18, 2025 · A computer network is a collection of interconnected devices that share resources and information. This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer. The addressing information complies with the Open Systems Interconnection (OSI) seven-layer model. Oct 5, 2020 · A network is a group of two or more computers or other electronic devices that are interconnected for the purpose of exchanging data and sharing resources. Dec 2, 2024 · You might hear that a network device is Layer 2, but what does that term mean? In computer networking, protocols operate within a structured framework known as the network protocol stack. Learn more. Physical Layer - Physical layer of TCP/IP model is responsible for physical connectivity of two devices. a large system consisting of many similar parts that are connected together to allow movement or…. Layer 2, Layer 3, and Layer 4 Switches What Is a Layer? A network switch connects devices and switches data between ports. Jul 11, 2025 · Prerequisite - TCP/IP Model, Network Devices 1. Essentially, it is a system that allows two or more devices to exchange information, resources, and services. The simple network definition: a system that links other subsystems together and allows them to share. ) to transfer data in a wide area network, or between one node to another in a local area network. NETWORK definition: 1. when signal is at any input port, this signal will be made at all output ports except The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. These devices can include computers, servers, printers, and other hardware. Sep 20, 2025 · A computer network consists of two or more computers that are connected to each other to communicate data electronically. Aug 26, 2025 · What is a Network? At its core, a network is a group of two or more devices connected together to share data, resources, and services. In this article Layer 2 protocols Layer 2 protocols or network L2 protocols are a list of communication protocols used by Layer 2 devices (such as network interface cards (NIC), switches, multiport bridges, etc. Mar 28, 2023 · Several core components are present inside a computer network. Some of the devices used in Physical layers are, Hubs: Hubs are devices commonly used to connect segments of a LAN. Dec 18, 2024 · Learn everything you need to assess various network types, topologies, and architectures. In computer science, computer engineering, and telecommunications, a network is a group of communicating computers known as hosts, which communicate data to other hosts via communication protocols, as facilitated by networking hardware. Networks can be wired (Ethernet cables) or wireless (Wi-Fi, Bluetooth, etc. It contains multiple input/output ports. Devices can be computers, servers, smartphones, routers, IoT devices, or printers. Switches use addressing information from the data packets they transfer to send data to the correct ports. This conceptual framework consists of multiple layers, each with specific roles and responsibilities in facilitating communication between devices. [2] The data link layer provides the functional and procedural means to transfer data between network entities and may also provide the means to detect and possibly correct Sep 29, 2022 · A layer serves the layer above it and is served by the layer below it.
