A network switch is a device that operates at the Data Link layer of the OSI model —Layer 2. It takes in packets being sent by devices that are connected to its physical ports and sends them out. A switch is a device in a computer network that connects other devices together. Multiple data cables are plugged into a switch to enable communication between different networked devices. Switches manage the flow of data across a network by transmitting a received network packet only to the one or more devices for which the packet is intended.

Network is a small group of computers that share information, or they can be very complex, spanning large geographical areas that provide its users with unique capabilities, above and beyond what the individual machines and their software applications can provide. The goal of any computer network is to allow multiple computers to communicate Switch:A network switch or switching hub is a computer networking device that connects network segments.The term commonly refers to a network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3 an Network managers with switches deployed in critical applications may want to have redundant links. In this case management is necessary. But for the rest of the networks an unmanaged switch would do quite well, and is much less expensive. Store-and-Forward vs. Cut-Through. LAN switches come in two basic architectures, cut-through and store-and. SWITCH: The Switch is the star of the network, it is the most active device, in charge of making sure that frames go where they need to go. These frames are units of data at Layer 2 (the Data-Link layer), of the 7 layers OSI reference model, and this is why switches are refer to as Layer 2 devices Network switch. A network switch also connects computers, like a hub. Where the switch differs from a hub is in the way it handles packets of data. When a switch receives data, it determines the destination and sends it directly to that device. It doesn't broadcast the packet to all computers as a hub does, which means bandwidth is not shared.

A computer network is made up of software and hardware components that allow one device to communicate with another. Hardware provides the set of instructions that utilizes the networking equipment for data transmission, whereas software specifies the sequence of commands (communication protocol) that uses the hardware equipment for data.

The network device is one kind of device used to connect devices or computers together to transfer resources or files like fax machines or printers. 2). What are the examples of network devices? The examples are switch, hub, bridge, router, gateway, modem, repeater & access point. 3) A network switch connects devices within a network (often a local area network, or LAN *) and forwards data packets to and from those devices. 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 Computer Networks Seminar PDF Report, PPT: A computer network can be defined as a set of two or more computers having interconnection to the same resources, such as exchange files, printers, CDs and other similar equipment.The networks in a computer are built with a great combination of software and hardware.

A bridge is a type of computer network device that provides interconnection with other bridge networks that use the same protocol. Bridge devices work at the data link layer of the Open System Interconnect (OSI) model, connecting two different networks together and providing communication between them. Bridges are similar to repeaters and hubs. Circuit switching is a switching technique that establishes a dedicated path between sender and receiver. In the Circuit Switching Technique, once the connection is established then the dedicated path will remain to exist until the connection is terminated. Circuit switching in a network operates in a similar way as the telephone works Message switching is a network switching technique in which data is routed in its entirety from the source node to the destination node, one hope at a time. During message routing, every intermediate switch in the network stores the whole message. If the entire network's resources are engaged or the network becomes blocked, the message-switched.

In this type of networking, there are usually few computers and other network devices, e.g., switches and routers involved (details about the devices are explained below). Metropolitan Area Network (MAN) MAN is a type of computer network that is larger than a LAN but not up to a WAN (Wide Area Network). It is an intermediary between LAN and WAN A network switch is a piece of hardware that facilitates communication between computers on an internal network. Without the switching function the devices could talk through the router to the greater internet but not to each other—something as simple as copying an MP3 from your laptop to your desktop over the network would be impossible Wireless Network Adapters . Each device you connect to a WLAN must possess a wireless network adapter. Wireless adapters are sometimes called NICs, short for Network Interface Cards.Wireless adapters for desktop computers are often small PCI cards or sometimes card-like USB adapters.Wireless adapters for notebook computers resemble a thick credit card By definit i on, a computer network is a group of computers that are linked together through a communication channel.
