网络：英文一般翻译为：internet ,network或.[Electrics] [Computer] a network。简单的来说，就是用物理链路将各个孤立的工作站或主机相连在一起，组成数据链路，从而达到资源共享和通信的目的。
凡将地理位置不同，并具有独立功能的多个计算机系统通过通信设备和线路而连接起来，且以功能完善的网络软件（网络协议、信息交换方式及网络操作系统等）实现网络资源共享的系统，可称为计算机网络。
网络一词有多种意义，可解作：
1、流量网络（flow network）也简称为网络(network)。一般用来对管道系统、交通系统、通讯系统来建模。有时特指计算机网络 (Computer Network)，或特指其中的互联网 (Internet)由有关联的个体组成的系统，如：人际网络、交通网络、政治网络。
2、由节点和连线构成的图。表示研究诸对象及其相互联系。有时用带箭头的连线表示从一个节点到另一个节点存在某种顺序关系。在节点或连线旁标出的数值，称为点权或线权，有时不标任何数。用数学语言说，网络是一种图，一般认为它专指加权图。网络除了数学定义外，还有具体的物理含义，即网络是从某种相同类型的实际问题中抽象出来的模型，习惯上就称其为什么类型网络，如开关网络、运输网络、通信网络、计划网络等。总之，网络是从同类问题中抽象出来的用数学中的图论来表达并研究的一种模型。
计算机网络是用通信线路和通信设备将分布在不同地点的多台自治计算机系统互相连接起来，按照共同的网络协议，共享硬件、软件和数据资源的系统。
实现网络的四个要素：
1、通信线路和通信设备
2、有独立功能的计算机
3、网络软件软件支持
4、实现数据通信与资源共享
远程终端联机阶段
计算机网络阶段（局域网）
计算机网络互联阶段（广域网、Internet）
信息高速公路阶段（高速，多业务，大数据量）
In general, the term network can refer to any interconnected group or system. Several different types of networks exist, including:
1. Human networks[Business network;Entrepreneurial network;Social network;Economic network;Old boy network; Sexual network ]
2. Media
Radio network, create and distribute radio programming through multiple channels that connect in a network
Television network, create and distribute television programming through multiple channels that connect in a network
Network (film), an Academy Award winning film from 1976
Nettwerk, a record label
The Network, a band
Network (comics), a name given to several Marvel Comics super heroes
Network (computer game), an economic simulation for the Apple II personal computer
3. Technology
Electrical network, a network of electrical components
Computer network, a network of computers
Computer networking, the scientific and engineering discipline concerned with this kind of network
Telecommunications network, a network of telecommunications links
Energy transmission and distribution networks
Electric power transmission network, a network of conduits for bulk transmission of electric power
Electricity distribution network, a network of conduits for delivery or short-haul transmission of electric power
Pipeline transport network, a network of pipes for transmission of gases, usually natural gas
Gas distribution network, a network of pipes for delivery of gases, usually natural gas or, formerly, town gas
Network Systems system network, a system of combined networks of main systems
4. Science, mathematics, and engineering
Network theory, the applied mathematics counterpart of graph theory, especially in combinatorial optimization
Flow network, an assignment of flow to the edges of a directed graph where each edge has a capacity
Network (mathematics), a type of diagraph in graph theory
Neural network, an interconnected group of biological neurons
Artificial neural network, an interconnected group of artificial neurons
5.Other
Transport network, facilities on which people and goods move
Spatial network, urban networks or networks of rooms within buildings
Network effect, a characteristic that causes a good or service to have a value to a potential customer dependent on the number of customers already owning that good or using that service
NETWORK (Catholic Lobby), a national Catholic social justice lobbying group based in Washington, DC.
