Local Area Networks :: essays research papers

local area networks Local Area Networks Local Area Networks in like manner c all tolded local area networks be possessed of been a major player in industrialization of computers. In the past times 20 or so years the worlds industry has be invaded with immature computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to destiny information between computers with a simple relatively inexpensive organisation of network cards and softw be. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting profligate because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings set(p) next to each other. For larger area need there are several other types of networks such as the Internet. LANs systems can be delimitate and connected in many differen t ways. This is the reason for the standardization for either one can have a common ground to commencement from. The LANs described Herein are distinguished from other types of data networks in that they are optimized for a moderate size geographic area such as a single 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 physiological medium on a point-to-point basis without any intermediate fracture 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 Wide Area Networks (WANs) that link communication facilities in different parts of a country or are used as a public utility. The se LANs are also different from networks, such as backplane buses, that are optimized for the interconnection of devices on a desk top or components within a single piece of equipment.(IEEE 802 example 1990) That is the standard definition for LANs by Institute of Electrical and Electronics Engineer commission 802. They are the committee used to set the standard in craftiness and operations for technicians that set-up and perform maintenance on LANs systems. And through all the technological words what they are trying to say is a LAN is a small area network that distributes information among computer in a small work environment unlike WANs that distribute information crosswise global areas.
