2) Local Area Network (LAN)

A Local Area Network or LAN as it’s commonly known is a network that connectsdevices usually in the same building or local area. This could be computers orother devices that are within an office building, which are connected togetherto share resources.Most people make use of this network type to share files and other business-related documents in an organization. A router is often used when multipleLocal Area Networks need to be connected to each other. A LAN is probably themost commonly used computer network nowadays. A major component of a LANnetwork is a Layer2 Ethernet Switch which provides the actual communicationbetween devices.

10) System Area Network

A System Area Network is a network that is designed to work in parallelcomputing environments; it connects computers that are in a High PerformanceComputing setting. These are often used where high processing is needed.Computer clusters make use of System Area Networks to achieve connectivity.The major difference here is the distance in between the computers on thenetwork, which is often a short distance.Difference Between LAN and WAN

LAN (Local Area Network)

A LAN is a group of computers and other network devices attached within alimited area like a house, a building, an office, an entire campus, etc. It isa widely used network of devices and can be set up in a limited geographicalarea without investing a huge cost like other networks. In most cases, LAN isused to form a network to share resources like printers, scanners, or fileslike audio, video, movies, software, games, etc. The simplest kind of LANexample is a connection formed between a computer and a printer within ahouse. Typically, it is a medium that helps transfer data across devices in alimited range area.Advantages:Few advantages of using a LAN are listed below: * Data can be transferred from one device to another networked device without any issue. * Data can be stored centrally in a single storage disk of the server computer. It will be a lot easier to secure the data in a single disk than all the separate disks. This also helps in data management. * LANs allow administrators to share a single internet connection across all the other connected devices. * Instead of purchasing any paid software for each system, users from different systems can use the same software from the server’s main computer over the network.Computer peripherals like hard-disk, Optical Disk Drive, and printer can sharelocal area networks that will reduce the hardware purchases’ overall costs.Using LAN, multiple computers can use the same printer or other connecteddevices.

Local Area Network (LAN)

Local area network is the computer network that connects computers within thelimited area such as schools, colleges or universities.Local area networks, generally called LANs, are privately-owned networks. Theyprovide a useful way of sharing resources between end users. The resourcessuch as printers, file servers, scanners, and internet are easily sharableamong other connected computers in a network.LANs are distinguished from other kinds of networks by three characteristics: 1. Their transmission technology 2. Their size 3. Their topology

Local Are Network (LAN) Uses

The history of video games reserves a very special space for the LAN networksince it was thanks to this possibility of connecting the equipment thatopened the doors to a new way of experiencing fun.At first, it broke with the limit of players who could compete or collaboratein the same game, which at the time was linked to the capabilities of eachconsole or computer and the creativity of the developers; but over time itserved as an experimental phase for the network of networks, the Internet.Although the LAN network may seem reserved to the business world, many playersstill enjoy their possibilities to have fun with friends or even to compete inthe most important tournaments in the world, where the instability of theInternet would be fatal.As in other aspects of computer science and electronics, experts have manyfactors in mind when assembling, optimizing and maintaining their localnetworks, from the brands and models of the components to the most remotedetails of the software configuration, to make sure you do not waste a singlefraction of a second.Also Read: Top 5 Antivirus Software for Windows 7, 8, 10 in 2019The Difference Between LAN & WAN in Wireless RoutersA WAN is a network covering any large geographic area. WANs can be as large asa state, a country, or the world. The Internet itself is a type of WAN,because it covers the entire globe. Although a network connecting LANs in thesame city, like a group of offices belonging to the same company, these areusually called metropolitan area networks.

LAN (Local Area Network) and WLAN (Wireless Local Area Network)

LAN is a local network that consists of a group of computers and devicesconnected via a single physical network (cables). It is limited to a specificgeographic area/location.An excellent example of this kind of network would be a library, office, orhome. I don’t think most of us use a LAN in our homes these days, because aLAN connects devices via cables. Nowadays, our devices are connectedwirelessly via WIFI, so we’re talking about WLAN.

Local Area Network (LAN)

A LAN is a network of connected IP devices. It can include both machines, suchas desktops and laptops, and non-human interfaces, such as printers.Apple’s current default operating system for the Mac product family, includingboth desktops and MacBook laptops.Malware refers to any software that’s created with an intent to cause harm. Itcan include traditional viruses as well as newer forms of malicious softwaresuch as adware, spyware, worms, and Trojans.

Types of Computer Networks

According to the size, distance, and structure, a computer network can bemainly classified into four types:•PAN (Personal Area Network)•LAN (Local Area Network)•MAN (Metropolitan Area Network)•WAN (Wide Area Network)Apart from the mentioned networks, there are some other networks that we havealso explained below.Let’s understand all of these networks in details:

Wireless Local Area Network

A Wireless Local Area Network or WLAN is a network that is used to connectdifferent devices by using radio or infrared signals within a limited area.WLANs are established by using a device known as anAccess Point (AP)to the edge of the wired network.These APs are considered as the base stations for the wireless network.Wireless clients such as mobile devices, laptops, or fixed devices havingwireless adaptors can communicate with the AP for data transmission. The WLANsare usually established in home, school, or office building. It can be publicor private depending on the requirement.

LAN or Local Area Network: – It is a computer network that covers a small

geographical area like an office building, school, colleges etc., where wiredor wireless LAN network is used for connecting devices like PC’s, printers toInternet. Wired connection can be done through cables like twisted pair wire,co-axial or optical fiber cable for speed data transmission. SimilarlyWireless LAN network is performed through radio wave technology or Infraredcommunication that helps to connect multiple devices within an area. Ethernetor IEEE 802.11LAN is used for connecting a device to a router or modem forspeed data transmission. The five main components of LAN are networkingdevices like workstations, printers, servers that can be accessed by otherComputers, network communication devices like router, hub, and switches forconnectivity, NIC or Network Interface card, Cables as medium and a NetworkOS.

Classification of Computer Networks based on network topology

Based on [the network topology], computer networks can be distinguished:bus topologystar topologyring topologyThe purpose of a computer network:1. Networks allow more efficient management of resources: for example, manyusers can share a single printer with high quality, compared to using lowquality printers at each desk. In addition, software license network can becheaper than a separate stand-alone license for the same number of users, andshare the use of the CPU, Memory, and hard disk.2. Networks help maintain reliable information and to keep up-to-date: thecentralized data storage system managed allows multiple users to access datafrom a variety of different locations, and restrict access to the data whileit is being processed.3. Networks help speed up the process of sharing the data (data sharing).Transfer data on the network is always faster than other means of data sharingnetwork instead.4. Networks allow groups working to communicate more efficiently. Letters anddelivery of electronic messages are the substance of most of the networksystem, in addition to scheduling systems, project monitoring, onlineconferencing and groupware, which all help teams work more productively.5. Network helps businesses to serve their clients more effectively. Remoteaccess to centralized data allows employees to serve clients in the field andthe clients can directly communicate with the supplier.6. In order to achieve the same goal, every part of a computer network andprovide the service requested. The party requesting the service is called theclient and the service is called service (server). This architecture is calledclient-server systems, and is used in almost all computer networkapplications.

Local area network (LAN). Computer and Network Examples

A local area network (LAN) is a devices network that connect with each otherin the scope of a home, school, laboratory, or office. Usually, a LAN comprisecomputers and peripheral devices linked to a local domain server. All networkappliances can use a shared printers or disk storage. A local area networkserve for many hundreds of users. Typically, LAN includes many wires andcables that demand a previously designed network diagram. They are used by ITprofessionals to visually document the LANs physical structure andarrangement.The Network Logical Structure Diagram is designed to show the logicalorganization of a network. Shows the basic network components, networkstructure, and determines the interaction of all network devices. The diagramdisplays basic devices and zones: Internet, DMZ, LAN, and group.
