How can two different types of computer networks communicate with each other?

Two different types of computer networks can communicate with each other because they use the same network protocol; a network protocol is a set of rules, standards or conventions established for data exchange in a computer network. Two networks To be able to exchange data or communicate, it depends on whether the communication protocols of the two networks are compatible with each other. Interoperability means that data and communication can be exchanged between the two networks.

Why two different types of computer networks can communicate with each other

The reason why two different types of computer networks can communicate with each other is because they use the same network protocol

What is a network protocol

Network protocol is a collection of rules, standards or conventions established for data exchange in a computer network.

For example, a microcomputer user in the network communicates with a mainframe operator. Since the two data terminals use different character sets, the commands entered by the operators do not recognize each other. In order to enable communication, it is stipulated that each terminal must first convert the characters in its own character set into the characters in the standard character set before entering the network for transmission. After reaching the destination terminal, it is then converted into the characters in the terminal's character set. Of course, for incompatible terminals, in addition to changing the character set characters, other characteristics such as display format, line length, number of lines, screen scrolling method, etc. also need to be changed accordingly.

Peer entities usually refer to information units at the same level in the computer network architecture. The general system network protocol includes five parts: communication environment, transmission service, vocabulary, information encoding format, timing, rules and procedures. In 1969, when the U.S. Department of Defense established the ARPA Computer Network, the earliest network, it issued a set of military standards for computer communication protocols. It included five protocols. It is customary to use TCP and IP as this set of protocols. general name.

TCP/IP is the official network protocol of the Internet. It is a set of protocols that provide interconnection functions between many independent host systems. It regulates the transmission, interpretation, execution, and interoperability of all computers on the Internet when they are interconnected, and solves The interconnection, interoperability and operability of computer systems are recognized as international industry standards for network communication protocols. TCP/IP is a packet switching protocol. Information is divided into multiple packets for transmission over the Internet. After reaching the receiver, these packets are reassembled into the original information. In addition to TCP/IP, commonly used network protocols include PPP, SLIP, etc.

Extended analysis:

For two networks to be able to exchange data or communicate, it depends on the communication protocol of the two networks. Not mutually compatible. Interoperability means that data and communication can be exchanged between two networks.

For example, in the Internet, the TCP/IP protocol shields the differences in physical networks and can ensure normal communication between computers in different interconnected networks. But it is not required to use TCP/IP.
