Information About Computer Networking & Local Area Networks

Local Area Networks

Local area networks, also known as local area networks, are a major player in computer manufacturing. In the last twenty or so years, the global industry has invaded new computer technology. This impact has influenced the way we do business, which has become necessary with the growing need for improvement. Local networks allow the employer to share information between computers using a relatively simple and inexpensive system of network cards and software. It also allows the user or users to share devices such as printers and scanners. The speed of access between computers turns on quickly because the data has a short distance to go. In most cases, the local network will occupy one or more buildings side by side. Several other types of networks, such as the Internet, are needed for more space.

LAN systems can be defined and connected in different ways. This is why the unification of each can have a common basis. “The local networks described here correspond to different types of data networks because they are optimized for a medium-sized geographic area, such as a single office building, warehouse, or campus.” The IEEE 802 LAN is a peer-shared network. -to-peer that transmits information to all stations for reception,, Does not guarantee confidentiality by nature, when the local network allows stations to communicate directly using a common physical medium point by point without resorting to a node of Intermediate switching It is always necessary to have a secondary access layer to control access to common support, the network is owned, used and managed in general By an organization Unlike WANs that connect communication facilities in different regions of a country or which are used as public services, these local networks also differ from networks, such as backplane buses that have been upgraded to interconnect devices on a surface. Desktop or components within the same equipment. “(1990 IEEE 802 standard) This is the IEEE 802 standard definition of local area networks. It is the committee that sets the standards for the manufacture and operation of technicians who prepare and maintain network systems. In all technical terms, what they are trying to say is LAN, a small network that distributes information between computers in a small work environment, unlike WANs that distribute information across multiple regions of the world. “The local network usually belongs to the same organization that owns the connected devices. This is often the case for extended networks or at least a large part of the network’s assets are not. Caution when choosing a local network, where capital investment can be significant (compared to connection fees or rented for large-scale networks) for purchase and maintenance, and second, the responsibility for network management for the local network. (Local networks and urban networks 1997).

The question now is that you have a standard and you have a connection now how do you use the system to make it work perfectly? “Networks use protocols or rules to share information on a single shared connection, which avoids simultaneous data conflicts between two or more computers, computers in most local networks use protocols called Ethernet or Token Ring. the computer connected to an Ethernet network Using a shared connection and otherwise the computer transmits the data. At the same time, the sent computers continue to monitor the shared connection and stop the transmission in the event of a collision, and transmit Token Ring protocols to a special message called a token For a computer, the computer that receives the token receives permission to send a packet of information or, if the computer does not have a packet to send, transmit to the next computer. “(Microsoft 2000 LAN) The current user program handles most of the management tasks. we.
