It can realize high-speed, reliable, safe and flexible data transmission. It mainly has the following functions:
Realize high-speed data transmission: Ethernet adopts high-speed transmission technology, which can realize Gbps-level data transmission speed and meet the requirements of fast data transmission speed.
Improve network reliability: Ethernet adopts multi-channel access technology to realize the sharing of network resources by multiple computers, which improves network reliability and reduces the incidence of network failures.
Improve network security: Ethernet adopts security mechanisms, such as MAC address filtering, VLAN and other technologies, to ensure the safe transmission of data.
Support flexible topology: Ethernet supports star, bus, ring and other topological structures, which can be configured according to different network application scenarios.
Lower cost: Ethernet adopts cheap hardware and easy-to-maintain topology, which greatly reduces the cost of network construction and maintenance.
In short, Ethernet is a mature, stable and widely used LAN technology. Its high-speed data transmission, reliability, security, flexibility and low cost make Ethernet play a vital role in modern computer networks. Role is one of the key technologies to ensure network communication.
