The classification of WAN and LAN in computer networks is based on the network connection distance; LAN can be used in a small area, WAN is designed for long-distance communication and has the widest coverage, and the scope of MAN is Between LAN and WAN.

What is the classification of wide area network and local area network in computer network?

The classification of wide area network and local area network in computer network is based on network connection distance. The

WAN is a remote network that connects local area networks or metropolitan area network computer communications in different areas. The coverage of a local area network is generally within a few kilometers. It has the advantages of convenient installation, cost saving, and expansion. Its convenience and other features make it widely used in various offices.

  • Local area network can be used in a small area, and the coverage is usually limited to 10 kilometers;

  • Metropolitan area network, The scope of action is between the wide area network and the local area network, and the coverage can usually extend to the entire city; country, or even the entire world.

  • Computer network refers to the connection of multiple computers and their external devices with independent functions in different geographical locations through communication lines. In the network operating system, network management software and network communication A computer system that realizes resource sharing and information transfer under the management and coordination of protocols.

  • Computer networks are mainly interconnected by some general-purpose, programmable hardware that is not designed to achieve a specific purpose (for example, transmitting data or video signals). These programmable hardware can be used to transfer many different types of data and support a wide and growing number of applications.

Definition ClassificationWhat are the classifications of wide area networks and local area networks in computer networks?

Computer network is also called computer communication network. The simplest definition of a computer network is: a collection of interconnected, autonomous computers that share resources. If this definition is used, the early terminal-oriented networks cannot be regarded as computer networks, but can only be called online systems (because many terminals at that time cannot be regarded as autonomous computers). But as hardware prices fall, many terminals have a certain degree of intelligence, so the strict boundaries between "terminals" and "autonomous computers" are gradually lost. If a microcomputer is used as a terminal, according to the above definition, the early terminal-oriented network can also be called a computer network. In addition, from a logical function point of view, a computer network is a collection of computer systems that use communication lines to connect multiple computers for the basic purpose of transmitting information. A computer network consists of transmission media and communication equipment.

From a user's perspective, a computer network is defined as follows: there is a network operating system that can be automatically managed by the user. It calls the resources called by the user, and the entire network is transparent to the user like a large computer system.

A more general definition is: using communication lines to connect geographically dispersed computer systems and communication equipment with independent functions in different forms, and realizing resource sharing and communication with fully functional network software and protocols. information transfer system.

Generally speaking, a computer network is a system that interconnects computers distributed in different geographical areas with specialized external devices using communication lines to form a large-scale and powerful system, so that many computers can communicate with each other conveniently. Information, sharing hardware, software, data information and other resources. Simply put, a computer network is a collection of many autonomous computers interconnected by communication lines.

The simplest computer network has only two computers and a link connecting them, that is, two nodes and a link.

Press to connect

A computer network is a collection of autonomous computers interconnected through lines. To be precise, it is a collection of independent computers distributed in different geographical locations. A system that connects capable computers, terminals and their ancillary equipment with communication equipment and communication lines, and configures network software to realize computer resource sharing.
