 Local Area Network (LAN) LAN stands for " Local Area Network ". It is a computer network that connects devices within a small geographical area, such as a home, office, or building .A LAN typically consists of multiple computers, printers, and other devices that are connected together using cables, wireless connections or a combination of both. The primary purpose of a LAN is to enable communication and resource sharing between devices on the network. For example, multiple users can access the same printer, share files, or play games together. LANs can be found in a variety of settings, from small businesses to schools and homes. They are often easier to set up and manage than larger networks, such as wide area networks (WANs) that connect devices over a larger geographic area. Advantages of LAN: Following are the advantages of using Local Area Network (LAN). Resource sharing: With a LAN, users can share resources such as printers, scanners, and internet connections, which

 What is Router A router is a networking device that connects multiple devices and networks together, and it manages the flow of data between multiple devices and networks. Routers are commonly used in homes, businesses, and other organizations to create and manage computer networks. A router operates by directing traffic between devices on the network. When a device on the network sends data to another device, the router receives the data and determines the most efficient path to send it to its intended destination. The router then forwards the data packet to the appropriate device or network. Routers come in different sizes and configurations, ranging from small home routers to large enterprise-class routers that can handle massive amounts of data traffic. Some routers are designed for specific purposes, such as providing wireless connectivity or connecting multiple locations together in a wide area network (WAN). Advantages of Router: Following are some advantages of using routers.

What is Peer-to-Peer Network Model/Architecture? Advantages & Disadvantages

By -
Image
 Peer to Peer Network Model A peer-to-peer (P2P) network model is a type of network architecture in which multiple computers (known as peers) are connected to each other without a central server or a hierarchy of clients and servers. In a peer-to-peer network, each computer has equal status and can both receive and send data directly to other computers. This means that every computer in the network can act as both a client and a server, and can share resources such as files, storage space, or processing power. Peer-to-peer networks are often used for file sharing, online gaming, and communication applications such as Skype or Zoom. They are generally more decentralized and resilient than traditional client-server networks, as they can continue to function even if some computers in the network go offline.
