A local area network is defined by the extent of the area it can cover.
A local area network is defined by the extent of the area it can cover. It consists of nodes and computers connected to a central point that supplies the connectivity to help provide net to the local areas such as homes, schools or office blocks. Better still, it is a collection of devices in a physical location that provides net connectivity to all other peripherals in that location. Even though it may grow, it still remains localised at a single area, unlike the WAN that covers a large geographic area. The main reason for this connection is to share files of various sizes through that connectivity. All computers and other workstations should connect to a single internet connection provided by LAN protocol before they can begin to share information.
You will need a router, switches and cables to perform such connection successfully. A router provides IP address for each of the tools on the network. It also facilitates communication between them in the same network and is dependent on the structure used. A router is a device that can communicate with the internet through a modem. Modems facilitate internet communication by empowering routers with bandwidths to surf the web. Some have inbuilt modems while others have USB ports that can be used to link modems.
They fall into two categories according to their functionalities. Such routers connect to remote modems through such cables to transmit information to and receive information from the internet. Wired routers are connected to peripherals by wired connections. Through a USB port, they can link to modems by which they create communication between devices and the internet. To set up LAN, you must understand both its logical and physical structure that is crucial in how LAN works. Network topology is a description given to the physical and logical way in which devices, as well as network segments, interconnect. LANs perform their work through physical signal transmission parameters by which data travels logically by the network devices independent of their connectivity.
LAN comprises cables, switches and RJ45 connectors which are connected to a router, cable modem or ADSL modem to actuate net access. Firewalls, load stabilisers and network trespass detection all form part of a strong LAN system if properly configured. There are two main types of logical topologies, the logical bus topology, and the logical ring topology. The physical description consists of different structures such as star mesh, ring, point-to-point, circular, hybrid, and bus structure networks. These have different node configurations and links that follow the setup structure that is independent of each other.
Another important factor is that computers in a local area network, connect to one another by Transmission Control Protocol. This is a method that establishes and maintains network conversation between one or more computers, by which applications exchange information. Transmission control protocol works with net Protocol, the protocol that describes how a computer sends packets of data to each other. While LAN is localised at a given location, WANs are large and can only be operated by large companies, unlike LANs. Peripherals that share LAN connects to other networks such as WANs as well as Fibre. The difference lies in the topology of each of them although they perform the same functions.
WANs, due to the heavy investment of high-powered equipment, can carry more bandwidth compared to LANs. That means they are faster than LANs besides their ability to carry heavy loads of data. LAN systems are known to be limited to transfer of small packets of data per second. Any company that deals with heavy loads will find LAN systems slow. Unless you connect more LANs to a strong remote modem such as ADSL the performance may be poor. Even though both systems can support heavy data transfer, LANs will require more reinforcements to work better. WANs can use protocols such as WIMAX, UMTS, CDMA as well as GSM as well.
LANs, being a group of computers as well as peripherals that share a common communication, can be grouped to form a WAN. LANs are not as complicated as WANs in structure, meaning they don’t necessarily need highly skilful manpower to install. Some just need plugging in such that even layperson can use by following a video tutorial. For example, routers such as TP-Link routers can easily be configured by following manuals provided by the vendor. They are fast to set up, providing with graphs that contain the important information you may need during installation. LANs are commonly used even in remote areas where more sophisticated networks are yet to come.
