How to modify and configure LAN - Local Area Network

Whether you’re a home based user looking to connect several machines for printer and file sharing, or a business professional looking to establish connections between employees (even at multiple locations) following proper computer networking principles can help you arrive at a solution. When connecting multiple locations, the service is called a wide area network or WAN. At a local level a local area network or (LAN) can be used to connect computers and devices that are in the same physical location. This guide establishes the core principles behind LAN technology to help users better understand the networking process.

Local area networks can be used for many purposes including shared Internet access, file sharing, print sharing and several collaborative applications. LANs can be protected using firewalls which will limit the users that are authorized to enter your network from outside of the building.

There is both a technical and software based implementation to a local network, varying according to the setup. Most commonly today’s networks are linked by wireless connectivity which connects computers to a centralized data-clearing server access to this server provides the means by which multiple computers are able to communicate. Users can also set access rights on servers and printers to ensure only authorized users are allowed to gain access. These features are very helpful limiting access to confidential data or keeping children off of the Internet when un-supervised.

An internal network, or intranet, is usually in the form of portal based communication software which allows users to access a series of shared applications. Internet access can be limited to keep employees or children off of websites that are not business related or appropriate.

On your LAN you can easily setup shared services such as file and print sharing. Devices can either be connected via a wireless router or hardwired using Ethernet cabling. Due to advances in wireless technology and security, many companies choose wireless over wired applications.

Computers that are authorized on the network transparently log into a shared router. Since access to the LAN is password protected, individual users are able to access the shared resources only with proper authorization. Most networks offer a shared repository of files and data that can be easily shared with many users. Each individual folder can be shared only with the people that require access to perform their job duties. Today’s complex networking software enables network administrators to connect remote machines in a secure manner to keep your business running smoothly.
