Networking Basics as you know is a computer network that makes it possible to share data with each other and networks resources such as an Internet connection. Local area networks that are discussed before in a recent chapter is a computer network supporting users in a small geographical area. Each user that has an Internet connection on a LAN is called a node, these nodes are configured to a peer to peer client. IN metropolitan area, networks, they connect to servers and clients that is larger than a single office or building. There are many types of topologies which is a connection to all nodes on a peer LAN with a single cable. There is another which is called ring and star topology which both connect to a separate node to a central device or hub that transmits or passes directly to that destination. Another technique we also learned about in another chapter would be transmission media, this is a network that is a cable and wireless media such as coaxial twisted pair and fiber optic cable infrared transmissions, one example of that would be a blue tooth that RF technology that sends and receives wireless between devices.
