The Principles of Computer networking
Whether you want to connect a few PC’s for file sharing and printer access or you wish to connect several business sites, using a Chicago computer networking professional can help you achieve your goal. On a larger scale, these networks can be used to comprise a wide area network (WAN) which encompasses a larger geographical space. 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 Network
Connecting to other computer users through a network can allow individuals to gain access to a wide variety of collaborative opportunities ranging from file sharing to gaming and real time communications. Users can protect local networks through firewalls which limit access to the network according to IP address, ensuring that unauthorized users don’t have the same connectivity as standard computer users.
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. This is particularly useful in cases where families want to limit the access of younger children, or when companies want to safeguard confidential data to only a certain group of employees.
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.
Proper LAN Setup
On your LAN you can easily setup shared services such as file and print sharing. Most commonly offices are connected remotely through wireless access, although a network can also be hard wired through Ethernet cables. 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. The shared router is password protected and all access that does not include the key is denied. Most networks offer a shared repository of files and data that can be easily shared with many users. With file sharing hierarchies it’s possible to implement safeguards to ensure your data is protected and only visible to authorized users. Network administrators can connect even to users outside of the building to troubleshoot problems and keep your technology running smootly.
