Transmission Medium Hubs Switch Router Information Technology essay
A switch is a network device that operates at the data link layer of the OSI model. It connects multiple devices within a local area network LAN and facilitates the exchange of data packets between them. Unlike hubs, which simply broadcast data to all connected devices, switches intelligently forward packets only to the intended recipients. A hub is a network device that connects several network nodes, for example in an Ethernet, in a star configuration. In the OSI Open Systems Interconnections reference model, hubs are classified as devices that operate at the physical layer. Their main task is to connect different computers and immediately transmit received data. Routers, Hubs, Switches and Bridges are all devices that connect networks. A network connection device is a device that connects two or more devices present in the same or different networks. A network connection device can be a repeater, hub, bridge, switch, router, or gateway. But in this blog we focus on hubs. Computers communicate with each other and with the Internet in different ways. This communication is made possible by routers, bridges, switches and other hardware. Tech Talker explains what these devices are. Switches or bridges create a network of devices that share resources. Just like the hub, it connects multiple LAN components together. A switch can also reduce collisions in a shared channel. There are types of switches: unmanaged, switch: multi-port switch. Managed, switch. Managed, switch: multi-layer switch. In this post you will find ways for video surveillance transfer. 1.Traditional way, consisting of network camera, power supply, network cable. With integrated wiring, the power cord and network cable must be laid at the same time. The power supply can also be placed nearby via V AC, saving the power cord.
