Network Features Of Lan Network Essay

A network interface card is already present in the computers. The purpose of the network card is to enable the computers to connect together using a protocol in order to transfer packets of data. In order to connect the computers, a form of connection is required that links the computers. In this case the form of connection used will be ethernet (Science - Opposing Views, 2014).

1)A network is when two or more computers are connected together and are able to share data and communication.

A: LAN: LAN stands for Local Area Network. LAN is a network which cover a small area like colleges, schools or buildings.

A LAN is a ‘Local Area Network’. It is a small network of computers most often

Every Computer that connects to a network must have a Network Interface Card (NIC). Most new Computers have them built into the motherboard. It has one or sometimes more RJ45 socket(s) that connect to a modem. The older and deprecated version used to have RJ11 sockets to connect to the network. Due to it being extremely vulnerable to phreaking and war-dialing, it has now been replaced with

Wired network uses cables to connect devices to the internet, however, wireless network uses radio waves to devices to connect internet.

When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.

Crossover cable - A crossover cable is a type of twisted pair copper wire cable for LANs (local area network) in which the wires on the cable are crossed over so that the receive signal pins on the RJ-45 connector on one end are connected to the transmit signal pins on the RJ-45 connector on the other end.

Ethernet is typically the technology that is used to allow computers locally to communicate with one another. Computers that are close to each other they are connected by Ethernet.

Coaxial cable uses a single conductor in the middle of a cable and the central conductor is surrounded by an insulator which is called the dielectric. Coax cables have become obsolete. Unshielded twisted pair cabling, also known as UTP cabling, has become the most common used network cabling. UTP cabling consists of four twisted pairs of wire, which have a different number of twists per foot, all encased on one sheath. This cabling is graded by different categories. Category 5 is recommended for Ethernet speeds of 100 Mbps. Category 5e, for running gigabit Ethernet or 1000BaseT networks. Category 6 and Category 6a are used to give better performance at higher speeds. Fiber optic cable is wave guided or light guided because it guides the light waves along the length of the cable. Single mode fiber optic cable can operate over long distances. Because fiber allows one mode of light to propagate, light pulses put on the fiber keep their shape much longer. This allows the light pulses to travel much further without interfering with other

This created physical connection between PC’s and the network line. Connected data’s are transporting data’s through the network. Cable is a medium through which information usually moves to one network to another network.

Local Area Network or LAN for short is the term used for computer networks located at a single location such as a small business located at a singular location. They are generally used for businesses, organisations and the likes to transfer data amongst their systems as opposed to transferring data to outside of their location. A LAN typically will rely on wired connections due to the benefits of increased security and speed, but a network called a WLAN exists, which is a Wireless Local Area Network and this may prove useful for those who come to work using mobile devices such as laptops, phones, etc. WLANs are simply local area networks that consist solely of wireless connections using a wireless access point (WAP) as the central hub. However, LANs can be a mix of both wireless and wired.Typically in a LAN, systems connected to the network are able to share resources among each other, send data to servers and use peripherals such as printers, scanners &

A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model  network structure.

When the first computers were made, they couldn’t talk to each other if they weren’t the same type. But now with the standardising of components, it is now easier than ever for different computers to connect to each other in a LAN (Local Area Network).

Generally, every component in a network is called a node. Each node is further identified by the specific task it performs. A user's node is called a terminal or a workstation. This can be a "dumb" device, meaning it has no operating system, just a monitor and keyboard, or a "smart" node, meaning it can do it's own computing because of an internal central processor.
