Is the metropolitan area network a public network?
The metropolitan area network is a public network; the metropolitan area network is a computer communication network established within a city, referred to as MAN, which is a broadband local area network. Due to the use of local area network technology with active switching elements, the network The transmission delay is small and can be used as a backbone network, through which hosts, databases, and LANs located in different locations in the same city are connected to each other.

Is the metropolitan area network a public network?
The metropolitan area network is a public network. Metropolitan Area Network is a computer communication network established within a city.
Metropolitan Area Network is a computer communication network established within a city, referred to as MAN. It is a broadband local area network. Due to the use of LAN technology with active switching elements, the transmission delay in the network is small. Its transmission medium mainly uses optical cables, with a transmission rate of more than 100 Mbit/s.
An important use of MAN is as a backbone network, through which hosts, databases, and LANs located in different locations in the same city are connected to each other. This function is similar to that of WAN, but the two There are great differences in implementation methods and performance.
Based on a large LAN, usually using technology similar to LAN. One of the main reasons why MAN is listed separately is that there is already a standard: Distributed Queue Dual Bus DQDB (Distributed Queue Dual Bus), that is, IEEE802.6. DQDB is composed of dual buses, and all computers are connected to it.

The typical application of metropolitan area network is broadband metropolitan area network, which is based on IP and ATM telecommunications technology and uses optical fiber as the transmission medium to integrate data, voice and video services within the city. A multimedia communication network with high bandwidth, multi-function and multi-service access.
Broadband metropolitan area network can meet the growing demand for high-speed and high-quality data communication services from government agencies, finance and insurance, universities, middle and primary schools, companies and enterprises, especially the rapidly developing Internet user group. The demand for broadband high-speed Internet access.
The development of broadband metropolitan area networks has gone through a long period, from traditional voice services to image and video services, from basic audio-visual services to various value-added services, from 64 kb/s Basic services to leased line services of 2.5 Gb/s, 10 Gb/s, etc. With the development of technology and the increasing demand, the types of business are also constantly developing and changing.

What is an open network system in a communication network?
Aug 22, 2022 pm 02:17 PM
The open network system is an "all-channel communication network." An all-channel communication network is an all-round open communication network system in which all members can communicate and contact each other without restriction; in this communication network, the degree of centralization is low and the status difference between members is small. With high morale, members can express their opinions directly, freely and fully, which is conducive to brainstorming and improving the accuracy of communication. The disadvantage is that it can easily lead to low work efficiency.
What are the resource sharing functions of computer networks?
Jul 15, 2022 pm 04:29 PM
The resource sharing functions of computer networks include: 1. Hardware resource sharing, which can improve equipment utilization and avoid repeated investment in equipment; 2. Software resource sharing and data resource sharing, which can make full use of existing information resources and reduce the software development process. to avoid repeated construction of large databases; 3. Communication channel resource sharing means that the same channel can be used by multiple users at the same time, which can improve the utilization of channel resources.
What does a computer network system in a school belong to?
Jul 13, 2022 pm 04:43 PM
A computer network system within a school is a local area network (LAN). A local area network is a network composed of multiple computers used in a small area. The coverage is usually limited to 10 kilometers. It belongs to a small-scale network established by a unit or department. LAN can be divided into wireless LAN and wired LAN. Wireless LAN can transmit audio, video, and text. Now many companies and campuses are using wireless LAN.
What are the most prominent features of computer networks?
Jan 13, 2021 pm 03:13 PM
The most prominent feature of computer networks is resource sharing. Resource sharing is one of the main purposes for people to establish computer networks. Usually, the resources required by multiple users at the same time always exceed the number of actual physical resources of the system. However, using logical (or virtual) resource allocation to realize resource sharing can better handle this contradiction and improve the efficiency of computer use.
What are the topologies of computer networks?
Feb 22, 2023 am 11:30 AM
The topology of a computer network refers to the physical structure of nodes and lines formed by computers or equipment on the Internet and transmission media. It mainly includes star topology, bus topology, ring topology, tree topology, and hybrid topology. , network topology, switching power supply topology; among them, star network topology is the most widely used network topology.
Why does a company use an intranet?
Aug 22, 2022 pm 03:57 PM
Reasons for using an intranet: 1. Resource sharing, which can provide convenient sharing of software and hardware resources, especially in the direction of hardware resources. Office automation equipment such as printers and scanners are fully utilized. 2. Facilitate teamwork. Most modern LANs provide a platform that allows multiple users to work on the same file and always use the latest version. 3.
