Local area networks are required for connectivity to be established between systems in a limited range or area. There are certain aspects that are required to be looked into for creating a LAN setup. The role of networking hubs in creation of LAN needs to be understood first. LAN is a basic requirement at a workplace and even at home where several computers are used and connectivity needs to be established between them. Computers need to be joined in a LAN setup which allows easy sharing of resources like internet access, access to a printer, scanner or file directories.

Features of a networking hub
In order to create a wired hub network for LAN there are four basic components to consider. Ethernet wire is one where the physical cable helps to link the different computers, which provide nice connectivity between them. Ethernet cables can be sourced the same way you source a fiber optic tester. These cables are also known as twisted pairs which are plugged into network cards that are located inside every computer that exists in the LAN. Network interface cards are the other component of a networking hub. There is a vacant slot that exists inside each computer where such cards fit; in modern computers they come as an inbuilt feature. Networking hub is completed with a junction box. This has several ports that allow Ethernet cables to be plugged into that represent each computer that is on the LAN. The other aspect is the networking software that usually comes built into most operating systems of computers these days.
How LANs work?
When the computers are wired correctly to the hub such as with SFP+ transceiver and have the necessary software installed, the communication between the different systems happens fast. The networking hubs can broadcast the traffic that comes across the hub, which is then transmitted to the machines via the nodes. Every computer or node that exists on the LAN has a unique address; if the traffic coming along does not have the right address then such communication is not picked up by a machine. There are different features of modern networking hubs that are prevalent these days. The use of networking switches is one such phenomenon that allows full duplex functions which leads to information processing at faster speed. Again, cable or DSL services are also part of such services which introduce a router that has a built in switch. The router provides access to the internet with filtering capabilities and built in firewalls.
