Switches are typically small, flat boxes that contain a group of Ethernet ports — as few as 4 on a small home office switch that sits on a desk, or up to several dozen on a rack-mounted enterprise switch. The “loopback” device, which is a virtual interface available in most Linux environments to connect back to the same machine, is an example of this. The most common network devices include hubs, repeaters, bridges, switches, routers, gateways, and brouters (the latter two aren’t commonly used). These symbols help in visually representing the various components and their connectivity in a Nov 13, 2024 · A wireless network is a computer network that uses radio frequencies to connect multiple devices in the same location. Basic Terminologies of Computer Networks Basic if computer Networks Network: A group of Aug 21, 2025 · Network devices are physical devices that allow hardware on a computer network to communicate and interact with one another. Since many keyboards and mice are now wireless, "wired" is often used to describe input devices that connect to a USB port. 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.

A local area network (LAN) is a group of computers and peripheral devices that are connected together within a distinct geographic area, such as an office building or campus. Bridges operate at the Network Access Layer in the TCP/IP protocol stack. They allow us to share data, resources, and services among different devices and users. Dec 17, 2021 · Network hardware is defined as a set of physical or network devices that are essential for interaction and communication between hardware units operational on a computer network. Jul 2, 2025 · Computer networking is the process of connecting two or more computing devices to enable the transmission and exchange of information and resources. They can interconnect with other networks and contain subnetworks (subnets). A network, in the context of computer science and information technology, is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data. It translates the data from the computer into a format suitable for the network and vice versa. Jul 23, 2025 · A Local Area Network (LAN) connects devices within a limited area, like an office, building, or even a home. IoT devices Although similar, Internet of Things (IoT) and edge devices are not the same. Unlike a router, a switch only sends data to the single device it is intended for (which may be another switch, a router, or a user's computer), not to networks of multiple devices. yfj zdbvro tkqnab fwtpmtv rwyj tqtws hew wbqceh oqsdmw vyoq
