Networking devices are the machines that are responsible for connecting computer and other electronic peripheral devices for sharing files or resources such as printer, fax machines and more, based on fixed protocols. 14. Connect dissimilar networks together; used to divide up networks and reduce the amount of traffic on each network. In networking parlance, networks that use different protocols are dissimilar networks. It can detect faults and malfunctioning hardware . The essentials of any networking system are routers, wireless access points, and switches. The IP address would be used in the case of TCP/IP networks. Network service providers may consist of telecommunications companies, data carriers, wireless communications providers, Internet service providers, and cable television operators offering high-speed Internet access. It can also identify suspicious traffic, network congestion, capacity, or other bottlenecks. There are generally four types of switches. This includes private and public networks . Computer networks can be characterized on the basis of network topology on which the network is based. They are usually additionally complicated than switch and router. . Network device is the physical device that is used to connect computer hardware such as workstation, printers, faxes, scanners and other electronic devices to a computer network. Computer networks were first created in the late 1950s for use in the military and defense. Passive Hub- Passive network hub is used to collect wiring from the different power supplies and nodes of an active hub. A hub is the easiest in the network communication system family, a hub is the easiest, as it links LAN components with the same protocols. It has a single input and single output port, thus making it a 2 port device. Here we discuss the introduction, list of networking devices with advantages, respectively. Passive Hub : The passive hubs are the wire connection points that aid in the construction of the physical network. Such communication is necessary for real-time control and automation of various controllers and visualization stations. A gateway increases network flexibility by allowing multiple computers to be connected to a single gateway. gigapop (gigabit point-of-presence): Gigapop is short for gigabit point-of-presence , an access point to Internet2 , the network collaboration between universities and partners in industry and government to develop advanced Internet technologies and applications such as telemedicine and digital libraries. In order to transmit data, it uses IP address mentioned in the destination . An enterprise network spanning buildings, cities, and even countries, is called a wide area network (WAN). Any network has three main components: Physical Connections, Application Component, and the Network Operating System. Node is the computing device that is connected in order to exchange data over the network. In technical terms, packets are filtered and forwarded by physical address through a Bridge. Access points use the wireless infrastructure network mode to connect WLANs to wired Ethernet LANs. Wireless access points (WAPs) are devices that combine a transmitter and receiver (transceiver) to form a wireless LAN (WLAN). Some or all of an organizations network capabilities and resources are hosted in a public or private cloud platform and made available on demand. The router is mainly a Network Layer device.

Each of these devices have a specific purpose. Wireless PAN. When the information is centralized, error management becomes a lot easier. Gateway is a network device used to connect two or more dissimilar networks. Computer Networks UNIT III Network Devices (Hub, Repeater, Bridge, Switch, Router and Gateways) 1. Gateways are generally more complex than switches or routers. Alternative paths are important to maintain the stability of a network. Gateways serve as network entry and exit points because all data must pass through or communicate with the gateway before being routed. The purpose of networking devices is to enable smooth communication between different hardware connected to a network. On the other hand, intra-network devices, such as routers and switches, are internal components of the network. As a result, it combines the functions of a bridge and a router by routing some incoming data to the appropriate systems while transferring the rest to another network. Here, data is transferred via a fast and secure path. This type of network is called a peer-to-peer network. It can work either at the data link layer or a network layer. Network Devices: Network devices, also known as networking hardware, are physical devices that allow hardware on a computer network to communicate and interact with one another. computer network, two or more computers that are connected with one another for the purpose of communicating data electronically.
