Data network / standard interface
For scientific research, industry and trade, through a data network, such as LAN (local area network) and WAN (wide area network) communication is part of daily life. In the type of connection between the terminal data network are called network topology. In the local area network, bus, ring topology and star topology also has been shown to appear as a mixed network. The main data network using coaxial cable, twinax, pair or an optical data transmission.
The bus topology
All terminals are connected with the same cable. An example of a bus topology is Ethernet (Ethernet) system. The logical structure of the system, is often the physical structure, is the traditional bus architecture. Terminal connected to each may at any time to send information. If a conflict occurs during transmission and another transfer terminal, the conflict will be identified as a mistake, after a random period of time after the re send the information. The process is defined in the IEEE 802.3 standard.
Transmission speed is 10 Mbit/s.
The use of the coaxial cable:
10Base5
* yellow thick coax, with N connector
10Base2
* BLACK coaxial cable fine, with BNC connector
Ring topology
The most famous example of this topology is the token ring system. From a physical point of view, it can be designed into a star, but from the logical and functional point of view is the ring structure. In the terminal during communication, the system receives a packet from the terminal (token) and the token is sent to a specific neighboring terminals. In order to avoid conflict during transmission. The communication method in the IEEE 802.5 specification. The data transmission rate of 16Mbit/s. The special data cable form by two twisted pair, one pair for transmission, the other for receiving.
Star topology
All of the network terminal using a common node link. The topology used to (for example) the general building cable laying. In the building the laying of cables, the realization of common data network. Using EN 50173 or IEC 11801 as the criterion. The two standards describe the level 3 (main, auxiliary and third) the basic structure of cable laying and the performance of standard components. The third level (level) cable laying means connected between the outlet box and jumper wire rack. Using twisted pair conductor star arrangement, is set in the center of the hub. A floor area can be equipped with this type of cable is inserted the same system (RJ 45) connection. Due to the adoption of star shaped layout, increase the equipment would not cause problems later. Because of the structure of cable laying, convenient configuration and monitoring the state of regional.
Using (for example) fiber or coaxial cable to connect the center hub is connected to the building or floor on the distribution board. Design corresponding to the region in a tree structure.
The length of the wire from the central hub to the terminal connection box shall not be more than 90 meters.
For the cable laying of this type, usually use Ethernet (Ethernet), fast Ethernet (100Base T), token ring and ISDN system.
Standard interface
Over the years, these data transmission system in information technology has been defined as a standard interface. For example, V.24, V.11, RS 485 and TTY interface. In the building of the data transmission between the most commonly used interface is a RS 485 data transmission, this transmission used in production and machine data acquisition.

数据网络/ 标准接口

对于科研、工业和贸易来说，通过数据网络，例如LAN （局域网）和WAN （广域网）通信是日常生活的一部分。在数据网络的终端之间的连接类型被称为网络拓扑。在局域网中，总线、环形拓扑和星形拓扑也已被证明可作为混合网络出现。主要数据网络使用同轴电缆，屏蔽双导线馈电线，双绞线或光纤进行数据传输。

总线拓扑

所有终端都接在同一电缆上。总线拓扑的一个例子是以太网（Ethernet）系统。该系统的逻辑结构，通常也是物理结构，是传统的总线结构。每个相连的终端可在任何时间发送信息。如果在传送期间与另一个传送终端发生冲突，则该冲突将被识别为一个错误，在经过一段随机时间后再次发送该信息。在IEEE 802.3 标准中定义该过程。
传输速度为10 Mbit/s。
使用下列同轴电缆：
10Base5
* 粗的黄色同轴电缆，带N 接头
10Base2
* 细的黑色同轴电缆，带BNC 接头

环形拓扑

该拓扑的最著名例子是令牌环系统。从物理的角度来看，它可被设计为星形，但是从逻辑上及功能性来看是环形结构。在终端通信期间，系统从终端接收一个数据包（令牌）并将该令牌发送给一个特定的相邻终端。从而避免传输期间的冲突。该通信方法在IEEE 802.5 中规范说明。数据传输率为16Mbit/s。专用数据电缆由两对双绞线构成，一对用于发送，另一对用于接收。

星形拓扑

所有网络终端都采用一个共用节点链接。该拓扑用于（例如）一般的建筑物电缆敷设。在对建筑物敷设电缆时，实现普通数据网。使用EN 50173 或IEC 11801 作为准则。这两个标准描述了3 级（主、辅助和第三级）电缆敷设的基本结构以及所用组件的性能标准。第三级（水平）电缆敷设意味着在出线盒与跳线架之间连接。采用星形布置的双绞线导体，被集合在中心集线器中。一个地板区可装备齐全这样的电缆类型并与相同的插入式系统（RJ 45）连接。由于采用星形布置，日后增加设备不会产生问题。因为采用结构形电缆敷设，可方便地监视配置区域的状态。
采用（例如）光纤或同轴电缆将中心集线器连接到建筑物或地板配电板上。该区域的设计对应于树形结构。
从中心集线器到端子连接盒的导线长度不得超过90 米。
对于这种类型的电缆敷设，通常使用 Ethernet（以太网），快速以太网（100Base T），令牌环和ISDN 系统。

标准接口

多年来，这些数据传输系统在信息技术中已被定义为标准接口。例如V.24, V.11, RS 485 和TTY 接口。在建筑物之间进行数据传输最常用的接口是RS 485 数据传输，这种传输用在生产和机器数据采集方面。
