Choosing the right router will be determined by Ethernet interfaces matching the switches technologically inside the center of the LAN (local area network), a collection of devices connected together in a single physical location, such as an office or building.

Every LAN utilizes a router that will be a gateway connecting the LAN to other networks. Within each LAN, there will be a configuration using a single hub or one with multiple hubs or switches connecting the LAN to end devices.

Devices for Internetwork

The chief devices utilized for interconnecting networks are routers. Every router port provides a connection to a particular network, routing packets between the networks. Routers may also be utilized for interconnecting networks that use a different technology. Its LAN interface permits routers to make a connection with LAN media. This will usually be UTP (unshielded twisted pair) cabling.

Devices for Intranetwork

For the creation of a LAN, it will be necessary to choose the proper devices to form a connection between the end device and network. Typically, hubs and switches are the two most utilized devices. 

Hub

The main tasks of a hub are receiving a signal, regenerating it, and then transmitting the signal over every port. Hub utilization makes a logical bus, meaning the LAN makes use of multi-access media.

Costing less than switches, hubs are typically selected as intermediary devices inside a LAN that is very small or needs low throughput requirements or if there is a limited budget.

Switch

Delivering dedicated bandwidth for every port, a switch increases LAN performance. Moreover, a LAN switch can be utilized for interconnecting network segments of different speeds. Typically, switches are selected for the connection of devices to a LAN.

Even though more costly than a hub, a switch’s superior performance and reliability makes the investment worthwhile. A wide selection of switches with a variety of features that allow the interconnection of several computers in common enterprise LAN settings are available.

Part 2 will cover the factors influencing device selection.
