WAN: WAN is a computer network extending over a relatively large geographical area. WAN stands for: Wide Area Network. The WAN consists of more than two local area networks (LANs). LAN is also a computer network, but unlike WAN, it spans a relatively small area such as a home, school building, office building, or computer lab. The most well-known or popular WAN is the Internet. Unlike the LAN, the WAN is generally not owned by a single organization or company, but exists under distributed or collective ownership. The WAN is created by the connection between two or more local networks. For example, if you call the warehouse and ask if a product is in stock, the customer service provider will search the computer and check if they have it in their warehouse, if not over WAN they are able to see what warehouse in Auckland owns the product and you refer to it, so all the warehouses in Auckland are each small local networks and they are connected together to form a wide network and from there which is connected to all the warehouses in the country establishing an even wider WAN connection, allowing data to be received and transmitted from anywhere across the country. The LAN is connected to the WAN with a device called a router. Over the past couple of years, network connection methods have improved more and more, so the Internet is easier to access and much more convenient. About 10 years ago, it would have been difficult to play computer games due to the speed of the connection and slower received signals. But today, you no longer need to wait for a video to load or receive a message on the other side. the world. Below I have listed three different types of connections and explained how they work.D...... middle of paper ......ion, to change the path the route takes through a system in response to a change in conditions.TCPIPTCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP/IP is one of the communication languages ​​or protocols of the Internet. It is used as a protocol for private networks such as the Internet or Extranet. each computer receives a copy of the TCP/IP program when it accesses the Internet directly. TCP/IP has two layers; the upper layer and the lower layerThe upper layer, which is the transmission control protocol, maintains the assembly of files or messages into smaller packets when they are transmitted over the Internet and are then received by a TCP layer on the another computer. The bottom layer, which is the Internet Protocol, is designed to manage the address part of individual packets to ensure that they reach their destination..
