There are different types of computer networks, each of which may be classified according to the scale of their operations and purpose. One of the most common types of computer networks is LAN. But what is LAN?<\/p>\n\n\n\n<p>In this blog post, we will explain LAN or local area networks. We will also look at how a LAN works, its characteristics, and the different types of LANs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_LAN\"><\/span>What is LAN?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>LAN stands for local area network, which is a network of computers and other electronic devices that are all located in the same physical area. LANs can be found almost everywhere, including homes, public workplaces, and public libraries. The purpose of LAN is to allow computers and other peripherals located in the same area to connect and exchange information with one another easily.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Example-of-LAN-1024x559.jpeg\" alt=\"An Example of Local Area Network\" class=\"wp-image-4090\" width=\"768\" height=\"419\" title=\"\" srcset=\"https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Example-of-LAN-1024x559.jpeg 1024w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Example-of-LAN-300x164.jpeg 300w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Example-of-LAN-768x419.jpeg 768w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Example-of-LAN.jpeg 1100w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<p>LAN can only be functional when devices are linked to a network that can either be wired or wireless. When we talk about wired networks, we use ethernet cables, and WIFI is utilized in the case of <a href=\"https:\/\/www.pynetlabs.com\/security-of-wireless-networks\/\">wireless networks<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"History_of_LAN\"><\/span>History of LAN<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The history of LAN can be traced back to the 1970s when Xerox PARC developed the first Ethernet standard. Ethernet uses coaxial cables to transmit data at 2.94 megabits per second (Mbps).<\/p>\n\n\n\n<p>In 1980, the Institute of Electrical and Electronics Engineers (IEEE) standardized Ethernet as IEEE 802.3, which increased the data rate to 10 Mbps, and introduced twisted pair cables and hubs.<\/p>\n\n\n\n<p>In 1985, IEEE 802.4 introduced token bus LAN and in the consecutive year 1986, IEEE 802.5 introduced token ring LAN.<\/p>\n\n\n\n<p>In the late 1980s and early 1990s, LAN technologies such as FDDI, ATM, and Fast Ethernet emerged, offering higher data rates of 100 Mbps or more.<\/p>\n\n\n\n<p>Year after year, advancements have been made to meet different organizations&#8217; needs and provide better usability.<\/p>\n\n\n\n<p>We now have a basic understanding of &#8220;What is LAN?&#8221; and its history. Now let&#8217;s discuss the working of LAN.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_does_Local_Area_Network_works\"><\/span>How does Local Area Network works?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>We already have discussed that LANs are implemented either with the help of a wired network (cable) or wireless network (WIFI). When devices are connected with the help of a wired network, it is known as wired LAN. Also, when devices are connected with the help of a wireless network, it is known as wireless LANs.<\/p>\n\n\n\n<p>Below we have explained how LAN works with the help of a diagram and the necessary components used in the working of LAN.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/How-LAN-Works.jpeg\" alt=\"How LAN Works\" class=\"wp-image-4091\" width=\"400\" height=\"400\" title=\"\" srcset=\"https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/How-LAN-Works.jpeg 800w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/How-LAN-Works-300x300.jpeg 300w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/How-LAN-Works-150x150.jpeg 150w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/How-LAN-Works-768x768.jpeg 768w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/figure>\n\n\n\n<p>When two or more computers and different components of LAN within the same geographical area are connected to a network switch, it forms a LAN. An Ethernet cable is used to make this connection.<\/p>\n\n\n\n<p>The network switch establishes a connection with a modem, which allows the delivery of internet connectivity.<\/p>\n\n\n\n<p>Technology such as CSMA\/CD guarantees that data is sent successfully through cable connections and that data packets are not in conflict with one another.<\/p>\n\n\n\n<p>The network interface card (NIC) is a hardware device that connects a computer to a local area network (LAN). With the help of NIC, devices can share data packets over the LAN, following the protocols and standards of the network.<\/p>\n\n\n\n<p>Local Area Networks are structured using switches and routers. The data packets are routed across the network with the help of the hardware that works as an interface and controls the connections between the various nodes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Types_of_Local_Area_Network\"><\/span>Types of Local Area Network<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Mainly there are two types of LAN. These are:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"ClientServer_LANs\"><\/span>Client\/Server LANs<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>It comprises a network of clients that communicate with a single server. Files, printers, and other network activity are all controlled by the server. A client may be any device that can access and use software, such as a desktop computer, a tablet, or a smartphone. Clients may connect to the server through wired or wireless networks.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Client-Server-LANs.jpeg\" alt=\"Client\/Server LAN\" class=\"wp-image-4092\" width=\"750\" height=\"375\" title=\"\" srcset=\"https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Client-Server-LANs.jpeg 1000w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Client-Server-LANs-300x150.jpeg 300w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Client-Server-LANs-768x384.jpeg 768w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Peer-to-Peer_LANs\"><\/span>Peer-to-Peer LANs<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>A peer-to-peer LAN consists of devices that act as both clients and servers. The devices can directly communicate and share resources with each other without requiring a central server. For example, a computer may share files and printers with other computers on the same network in a home LAN. This type of LAN is mostly used in homes.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Peer-to-Peer-LANs.jpeg\" alt=\"Peer-to-peer LAN\" class=\"wp-image-4093\" width=\"500\" height=\"350\" title=\"\" srcset=\"https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Peer-to-Peer-LANs.jpeg 1000w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Peer-to-Peer-LANs-300x210.jpeg 300w, https:\/\/www.pynetlabs.com\/wp-content\/uploads\/2023\/07\/Peer-to-Peer-LANs-768x538.jpeg 768w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/figure>\n\n\n\n<p>We already have explained the types of LANs; they can further be classified on the basis of topology.
