What is LAN. Local Area Network in simple words.

 LAN stands for Local Area Network. It is a computer network that connects devices within a limited geographical area such as a home, office building, or school.

A LAN can be established using wired or wireless technologies, including Ethernet cables, Wi-Fi, or Bluetooth. A LAN typically comprises a group of computers, printers, and other devices that are interconnected and can communicate with each other.

In a LAN, each device has a unique address, called the MAC address, which is used to identify it on the network. Devices can communicate with each other using a protocol such as TCP/IP, which enables data to be transmitted across the network.




Some of the key features of a LAN include high speed, low latency, and high reliability, as data is transmitted within a confined space and over a short distance. LANs are commonly used for sharing resources such as files and printers, as well as for accessing the internet and other external networks.

Overall, a LAN provides a cost-effective and efficient way for devices to communicate and share resources within a limited area.


Devices used in LAN network for data transmission:-

1. Switch

2. PC or laptop

3. Printer

What is SDWAN technology? SDWAN technology in detail.

Image
  SD-WAN (Software-Defined Wide Area Network) is a type of technology that enables organizations to connect their networks together and manage their traffic in a more efficient and cost-effective manner. Traditional WANs rely on expensive hardware such as routers and leased lines to connect different sites or branches of an organization. SD-WAN technology, on the other hand, uses software to intelligently route traffic across the most efficient network paths, including broadband internet connections, to improve network performance, security, and availability while reducing costs. Here are some key features of SD-WAN technology: Centralized management: SD-WAN technology provides centralized management of network traffic across different sites and branch offices. This allows administrators to set policies and rules for traffic routing, security, and other network services from a single location. Application-based routing: SD-WAN technology uses intelligent routing algorithms to dyn...
