1. Wired communication

Wired communication refers to the transmission of communication devices through cable connection, that is, transmission media such as overhead cables, coaxial cables, optical fibers, and audio cables.

1. Advantages. The biggest advantage of wired communication equipment is strong anti-interference, high stability, with a certain degree of confidentiality, fast transmission rate, the bandwidth can be unlimited.

2. Disadvantages. Line communication is affected by the environment, the expansion is weak, there is attenuation, construction difficulty, poor mobility, high cost.

3, commonly used cable communication equipment: television, telephone, optical terminal machine, computer, refrigerator, etc.

Two, wireless communication.

Wireless communication refers to the communication without physical connection line, that is, the use of electromagnetic signals can spread in the free space of a communication mode of information exchange.

1. Advantages. The biggest advantage of wireless communication equipment is the environment, which does not need to be limited by lines and has certain mobility. It can communicate through wireless connection in mobile state, with low construction difficulty and cost.

2, disadvantages, wireless communication equipment is weak anti-interference, slow transmission rate, limited bandwidth, transmission distance is also limited, low cost. However, wireless communication is changing the corresponding technology to make the transmission rate higher (802, 11N rate can reach 100Mbps is not lower than wired communication), more stable and convenient, so wireless communication equipment will be the development trend.

3, the common wireless communication equipment are: wireless LAN, satellite, radio, radio TV, mobile phone (mobile phone), mobile GPRS Internet access.

Both wired and wireless networks are helpful, be it for home use or otherwise. Both networks are different from each other, coming with unique sets of advantages you may find beneficial. It’s important to assess what you need best, as in the end, what matters is that your chosen network will do its job—to establish a good and stable connection
