What does LAN Band Table mean, what does WAN stand for, and what does MAC mean

lan: local area network.

wan: wide area network.

Local Area Network (LAN).

A local area network refers to the connection of more than two computers through transmission cables in a small geographical area to achieve resource sharing. The transmission speed of LAN is usually between 10MB s and 1000MB S, and 1000MB S for backbone and 100MB S for desktop are the current mainstream technologies. LAN is usually designed for a building, to improve the security of resources and information, to reduce the maintenance operations of managers, etc.

Customer service system (CS---B S) is a new application of modern local area network, which is mainly used in customer service database system. The client sends a request to the server, and the server returns the result to the browser or client program.

Wide Area Network (WAN).

A WAN is a network that connects multiple computers to communicate with each other and share resources within a large geographical area. Compared with LAN, the transmission speed of WAN is comparatively much slower. There are several types of road connection forms, such as ** line and special line.

In people's minds, it is always believed that the difference between WAN and LAN is that WAN is a network that realizes communication between geographically distant places through ** lines. However, with the development of communication technology and network technology, this definition is no longer accurate, and accordingly, people will gradually dilute the boundary between WAN and LAN, or it can be said that the LAN of different places will be connected together to form a WAN.

ADSL is to allow users to connect to the WAN, and its connection method is done through the **line), so we can think that the LAN exit of the router (3-4, more can be converted by other means) is LAN, and the **line end is WAN

The Internet we use is a service on the WAN.

Mac is the address of your computer's data card.

A Wide Area Network (WAN) is a cross-regional data communication network, usually involving a country or region. A WAN usually consists of two or more local area networks. Computers often use equipment provided by telecom operators as a platform for information transmission, for example through public networks, such as ** networks, connected to wide area networks, and can also be connected through dedicated lines or satellites.

The Internet is currently the largest wide area network. Compared with the OSI (Open System Interconnect) reference model, WAN technology is mainly located at three levels: physical layer, data link layer, and network layer.

Mac is the physical address.

LAN is a local area network and WAN is a wide area network. The Internet we use is a service on the WAN.

A MAC is actually a physical network address that identifies the link-layer address. In a network, IP addresses and MAC addresses are mapped to MAC addresses. To put it simply, each NIC has a physical address, that is, a MAC address, and when accessing the host in the network, it is actually converted from the IP address to the MAC address through ARP to access it.

In addition, Mac is also an abbreviation for the famous Apple computer.

LAN and WAN are all ports and MACs are bound to the NIC address.

LAN means LAN, the LAN interface on the router is connected to the computer, and the WAN interface is connected to the network cable that enters the home.

There can be two ways of saying it: one is a functional definition and the other is a technical definition. The former defines a LAN as a group of desktop computers and other devices that are physically separated from each other by physical addresses and are interconnected in a way that allows users to communicate with each other and share computing resources such as printers and storage devices.

This definition applies to LANs used in office environments, factories, and research facilities.

In terms of the technical definition of a LAN, it is defined as a network system of computers interconnected by specific types of transmissions (such as cables, optical cables, and wireless**) and network adapters (also known as network cards) and monitored by a network operating system.

The distinction between functional and technical definitions is clear, with functional definitions emphasizing external behaviors and services; The technical definition emphasizes the material basis and method of composition required to form a LAN.

The name of the local area network (LAN) itself implies the locality of the geographic scope of the network. Due to the limitations of a smaller geographical range. For example, the current LAN transmission rate is 10MB s, and the FDDI transmission rate is 100MB s, while the backbone speed of WAN is currently only 64Kbps in China, and the on-line rate of end users is usually 64Kbps.

Currently, the topologies of LANs are commonly used as bus type and loop type. This is due to the limited geographical scope. These two structures are rarely used in WAN environments.

LAN also has a variety of features such as high reliability, easy scalability, easy management, and security.

A local area network (LAN) is a group of computers that are interconnected by multiple computers in a certain area. Generally, it is within a radius of several thousand meters. LAN enables functions such as file management, application software sharing, printer sharing, scheduling within workgroups, e-mail and fax communication services, and more.

A LAN is closed and can consist of two computers in an office or thousands of computers in a company.

Local area network (LAN) is a computer communication network composed of various computers, external devices and databases connected to each other within a local geographical range (such as a school, factory and institution), generally within a radius of several kilometers. It can be connected with a remote local area network, database or processing center through a data communication network or a dedicated data circuit to form a large-scale information processing system. LAN enables functions such as file management, application software sharing, printer sharing, scanner sharing, scheduling within workgroups, e-mail and fax communication services, and more.

LANs are strictly closed. It can consist of a few or even thousands of computers in the office. The main technical elements that determine the LAN are:

Network topology, transmission media, and media access control methods.

A LAN is composed of network hardware (including network servers, network workstations, network printers, network cards, network interconnection devices, etc.) and network transmission media, as well as network software.

A local area network (LAN) is a computer communication network that connects various computers, external devices and databases within a local geographical area (such as a school, factory and institution).

Local Area Network (LAN), as opposed to Wide Area Network (WAN), mainly refers to the computer interconnection network in a small area. This "small area" can be a family, a school, a company, or a **department. The public network and extranet often mentioned in BT, that is, the wide area network (WAN); BT often refers to private networks and intranets, i.e., local area networks (LANs).

A local area network is usually a network system that is distributed over a limited geographical area, generally involving a geographical area of only a few kilometers. The LAN is very dedicated and has a relatively stable and standardized topology.

A router is a device that connects the network of the unit with the network of other units or the Internet, and a broadband router is a device that supports a variety of broadband access methods and allows multiple users or LANs to share the same account to achieve broadband access.

LAN access is mainly a kind of broadband access mode that is provided for community or group users, this access mode first needs to arrange the network cable plug in each room, and after summarizing to the community or group switch, access broadband Internet through optical fiber, compared with ADSL Internet mode, LAN user does not need to add modem and splitter, and can apply for opening by preparing an ordinary computer with network card.

We often see various terms in life, and LAN is also a term that we often see, so what does LAN mean?

Introduction to LANLAN is the abbreviation of LocalAreaNetwork, which means local area network, which refers to a computer communication network composed of various computers, external devices and databases connected to each other within a local geographical range (such as a school, factory and institution).

The meaning and function of a local area networkA LAN is a private network that covers a radius of several kilometres, usually in or near a building, such as a home, office, or factory. LAN itself is faster, more stable, and simpler than other networks, and is widely used to connect personal computers and consumer electronic devices to share resources and exchange information.
