A switch that also operates at these higher layers is known as a multilayer switch. Segmentation involves the use of a switch to split a larger collision domain into smaller ones in order to reduce collision probability and to improve overall network throughput.
For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
The hub manages and controls all functions of the network. It also acts as a repeater for the data flow. In a typical network the hub can be a network switch, Ethernet hub, wireless access point or a router. The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub.
A modem and router work in tandem to deliver you an internet connection and then grant access to your various devices. Modem vs. router: The differences between the pieces of hardware that connect ...
A daisy chain is a group of connectivity devices linked together in a serial fashion. Hubs are often connected in this way to extend a network. However, hubs are not the only device that can be connected in a serial backbone. Gateways, routers, switches and bridges more commonly form part of the backbone. [14]
A switch can be connected to a router, cable modem, or ADSL modem for Internet access. LANs at residential homes usually tend to have a single router and often may include a wireless repeater. A LAN can include a wide variety of other network devices such as firewalls, load balancers, and network intrusion detection. [7]
A given headend may have between 1–12 CMTSs to service the cable modem population served by that headend or HFC hub. One way to think of a CMTS is to imagine a router with Ethernet interfaces (connections) on one side and coaxial cable RF interfaces on the other side. The Ethernet side is known as the Network Side Interface or NSI.
An early example of a wireless router The internal components of a wireless router. A wireless router or Wi-Fi router is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network.
