Local Area Networks :: essays research papers

LANs Local rural area Networks Local Area Networks also called LANs have been a major player in industrialisation of computing machines. In the past 20 or so years the worlds attention has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing demand for improvement. LANs will an employer the ability to share information amongst computers with a simple comparatively inexpensive system of net cards and software. It also lets the user or users share hardware such as Printers and s dissolveners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each separate. For larger area learn there are several other types of networks such as the Internet. LANs systems can be defined and connected in m all different ways. This is the background for the regularization for every one can have a parkland ground to start from. The LANs described Herein are distinguished from other types of data networks in that they are optimized for a moderate size geographical area such as a exclusive office building, warehouse, or a campus. The IEEE 802 LAN is a shared medium peer-to-peer communications network that broadcasts information for all stations to receive. As a consequence, it does not inherently provide privacy. The LAN enables stations to communicate directly using a common physical medium on a point-to-point basis without any intermediate switching node being required. There is always need for an access sublayer in order to arbitrate to access to the shared medium. The network is generally owned, used, and operated by a single organization. This is in contrast to large Area Networks (WANs) that interconnect communication facilities in different parts of a country or are used as a prevalent utility. These LANs are also different from networks, su ch as backplane buses, that are optimized for the interconnectedness of devices on a desk top or components within a single piece of equipment.(IEEE 802 Standard 1990) That is the standard definition for LANs by Institute of galvanising and Electronics Engineer committee 802. They are the committee used to set the standard in workmanship and operations for technicians that set-up and perform maintenance on LANs systems. And by dint of all the technical words what they are trying to say is a LAN is a small area network that broadcasts information among computer in a small work environment unlike WANs that distribute information across global areas.
