What is the difference between communication and communication?

At present, these two words are used frequently, but how to define the scope of meaning has not been clearly unified.

1. In the traditional sense, "communication" mainly refers to telephone, telegram and telex. The "message" of communication refers to the message, and the media message is transmitted from one end to the other through the communication network. The contents of media messages are mainly voice, text, pictures and video images. Its network is mainly composed of electronic equipment system and radio system, and the signals transmitted and processed are analog. Therefore, the word "communication" should refer to the process of realizing the above-mentioned media information transmission by means of telegraph, telephone and other media transmission systems.

2. "Communication" only refers to data communication, that is, end-to-end transmission of data is realized through computer network system and data communication system. The letter of communication refers to information, and the carrier of information is binary data. Data can express information in traditional media forms such as sound, image and animation.

Because the old "communication" system has realized the transformation of digitalization and computer networking, it can be considered that the current data communication system has covered the functions of the old "communication" system. According to this conclusion, at present, the word "communication" should be used more to represent the data transmission between the Internet and LAN, and the word "communication" should be used less or not as much as possible to avoid conceptual misunderstanding.
