Networks And Warfighting

Networking has given military leaders the power to transfer voice, video, ideas, reports, and files quickly, accurately, and efficiently to and from higher headquarters and commanders, and to the soldier in the foxhole on the battlefield. These abilities have made networking an invaluable tool for military leaders and their war-fighting efforts.

A Local Area Network (LAN) is a conglomerate of interconnected computers and or workstations sharing the resources of a single or many servers within a relatively small geographical location. Within the military LANs can be found in offices, whole buildings, ships and field units. They can even be dispersed throughout several buildings or through out entire bases. Throughout these local networks, military personnel are able to share files, information, communicate, and connect differen

A hub is a device used to concentrate and organize network wiring. There are two basic types of hubs, active and passive. A passive hub is simply a device that allows wiring connections in an orderly way. It requires no power and does not do any processing. The active hub contains circuitry that can filter, amplify and control data going through it. Active hubs are based on extending the network beyond the physical limits put on it via the transmission medium. In most networks today a device called a switch is replacing hubs.

Military networks range from the very secure to the typical network found in the business community and are designed relatively the same. A LAN is comprised of several pieces of hardware that enable connectivity of the network; these include network interface cards (NIC), hubs, switches, and routers. A LAN can be comprised of all of these parts and more, but can be constructed of less hardware. The hardware components of a specific network depend on the needs of the network and the security level desired.

A router is similar to a switch in that it can segment, filter, control and amplify data going through it. The main difference is the ability to be connected to several different networks at the same time, they are intelligent, and a router can also use different transmission mediums at the same time. They have the ability to segment networks into different networks and keep track of all of the computers on ea
