Understanding Network Infrastructure Management

Large businesses and offices have their own network of computers that are connected by wires to a grid. The hubs connects either to a central IT closet or to a shared internet cable. Large businesses tend to have more sensitive data. Many wired computers might connect to a fiber optic board or central switch that is monitored by a computer with network software. Problems arise occasionally, and troubleshooting these amounts to a process called network infrastructure management.

A few computers in a small office might be connected to a single hub or router. A wired connection is more secure than a wireless connection, although sharing a wireless router is still a common solution. Most people would not call this small amount of hardware a type of infrastructure, but the layers and systems can really add up in a big office.

A large number of computers need access to the internet, and yet that connection must be monitored to prevent hackers and malware from entering. Businesses go to lengths to keep their computer network clean, and large companies are in fact favorite targets for all manner of cyber criminals. Large networks use dedicated devices that create a firewall and isolate a network from unwanted traffic. In fact, there can be an internal and external data filtering device, and the room in the middle is called the demilitarized zone.

As mentioned, large networks are connected by a switch that is located in a wiring closet or IT room. Wires are connected in such a way that it is possible to tell which connections are not working. The switch is monitored by a network computer that is able to monitor the connections as well as connect to company hard drives or a mainframe. There are countless maintenance tasks possible, ranging from creating user accounts and passwords to blocking websites and granting website clearance.

A network technician understands the parts of a conventional network, including security devices, and is able to troubleshoot problems with Ethernet cables and other connection problems. Network technicians have an understanding of conventional operating systems as well as the network operating system.

Understanding typical operating systems, such as Windows and Linux, allows the technician to explore software solutions before deciding if the problem relates to hardware. More often, the problem is software unless a lot of changes were made recently. Network components do not contain moving, mechanical parts and so damage to them is infrequent.

Network infrastructure management involves every person that deals with the network. This means the technician, but also office workers who manipulate their personal systems and possibly connections in their office. It also involves the manager, who accesses the network and often has a fair amount of control over it. Communication between users is important.
