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.

城域网是公网吗Aug 31, 2022 am 10:53 AM

城域网是公网；城域网是在一个城市范围内所建立的计算机通信网，简称为MAN，属宽带局域网，由于采用具有有源交换元件的局域网技术，网中传输时延较小，可以用作骨干网，通过它将位于同一城市内不同地点的主机、数据库，以及LAN等互相联接起来。

计算机网络的资源共享功能包括哪些Jul 15, 2022 pm 04:29 PM

计算机网络的资源共享功能包括：1、硬件资源共享，可以提高设备的利用率，避免设备的重复投资；2、软件资源共享和数据资源共享，可以充分利用已有的信息资源，减少软件开发过程中的劳动，避免大型数据库的重复建设；3、通信信道资源共享，就是将同一个信道供多个用户同时使用，可以提高信道资源的利用率。

沟通网络中开放式的网络系统是什么Aug 22, 2022 pm 02:17 PM

开放式的网络系统是“全通道式沟通网络”。全通道式沟通网络是全方位开放式的沟通网络系统，所有成员之间都能进行相互的不受限制的信息沟通与联系；在这种沟通网络中，集中化程度低，成员地位差异小，士气高，成员可以直接、自由而充分地发表意见，有利于集思广益，提高沟通准确性，缺点是容易导致工作效率低。
