Local Area Network (LAN) refers to a computer group composed of multiple computers interconnected in a certain area. Generally within a radius of several kilometers. LAN can realize functions such as file management, application software sharing, printer sharing, scheduling within work groups, email and fax communication services, etc. A local area network is closed and can consist of two computers in an office or thousands of computers in a company.
Network hardware mainly includes:(Recommended learning: PHP video tutorial)
Network The server
is the core component of the computer LAN. The network operating system runs on the network server, and the efficiency of the network server directly affects the efficiency of the entire network. Therefore, high-end computers or dedicated server computers are generally used as network servers.
Network workstation
A network workstation is a personal computer connected to the network through a network interface card. It can serve users as an independent personal computer, and can also be used according to the needs of users. Grant certain permissions to access the server. In a network, a workstation is a user of network services. The main function of the workstation is to enjoy various services provided on the network.
Network interface controller
Also known as network adapter (network adapter), network interface card (network interface card), it is a piece of equipment designed to allow computers to operate on a computer network Computer hardware for communicating on. Because it has a MAC address, it belongs to Layer 1 of the OSI model, which allows users to connect to each other via cables or wirelessly.
Hub
The English name is "Hub". The main function of the hub is to regenerate, shape and amplify the received signal to expand the transmission distance of the network, while concentrating all nodes on the node centered on it. It works on the first layer of the OSI (Open Systems Interconnection Reference Model) reference model, which is the "physical layer". Hubs, like network cards, network cables and other transmission media, are basic devices in the local area network.
twisted pair
Twisted pair (TP) is the most commonly used transmission medium in comprehensive wiring projects. It is composed of two wires with insulation protection. Made of layers of copper conductors. Two insulated copper wires are twisted together at a certain density. The radio waves radiated by each wire during transmission will be offset by the radio waves emitted by the other wire, effectively reducing the degree of signal interference.
