关键词:拓扑结构计算机系统topologynetwork systemmedium

摘要:本文是一篇计算机留学论文。拓扑结构在现代计算机系统中运用越来越广泛。拓扑结构有很多不同的类型。主要分为两种类型:总线拓扑和点对点拓扑结构,点对点拓扑又包含环型拓扑,星状拓扑,此外点对点拓扑还包含网状拓扑(网格拓扑)。本文简要叙述了拓扑结构是如何操作的。

拓扑结构是计算机系统中各部分的连接部分,或者使用连通的节点连接在一起。因此,它是完完全全的互联网络结构。拓扑结构可分为两种类型。总线拓扑和点对点拓扑结构。总线拓扑主要只有一个分支,但点对点拓扑包含环型拓扑,星状拓扑,此外点对点拓扑还包含网状拓扑(网格拓扑)。


局域网拓扑结构

在一个局域网系统中,计算机通过网络媒介的形式连接起来。这一媒介被作为网络信号传输的方式。网络媒体的类型,网络的布局方式根据其应用的方式而略显不同。所以,拓扑结构依赖布局及其结构。工作站连接到网络的这样一个过程客观描绘了拓扑结构。


总线拓扑结构

在总线拓扑结构中,计算机通过一组电线连接,称为总线。总线拓扑结构连接所有网络设备的电缆作为中央骨干。数据可以通过直线从一个位置传输到另一个地方。一台计算机通过广播接收方的地址将数据传输到接收方地址和数据总线。但在实践中只有一台电脑可以同时发送数据。其他人必须等待发送数据。在总线拓扑结构中,网络通信散布到整个网络。但是总线拓扑结构主要用于局域网拓扑。但是今天,在星形拓扑结构中也比较常见。


How the topology operates

Topology is the link between the parts or the connecting together in a computer system using interconnected nodes. So, it is the fully interconnected network structure. Topologies can be divided into two types. They are Bus topology and Peer to Peer topology. Bus topology is mainly one branched but Peer to Peer topology contains Ring topology, Star topology. And Peer to Peer also contains Mesh topology (Grid Topology).


LAN topologies

In a local area network system, the computers are connected by the form of networking medium. And this medium provide as the way for the network signal transmitted. For the types of network medium, the layout of the networks is the way it provided. So, the topologies depend upon the layout and its structure. The workstations physically connected to the network are described the topology.


Bus topology

In Bus topology, computers are linked through a single set of wires, called a bus. A bus topology connects all networking devices by a cable as a central backbone. Data can pass on a straight-line from one location to another. One computer transmits data to another by broadcasting the receiver address and the data over the bus. But, in practice only one computer can send data at the same time. The others must wait to send their data. In a Bus topology all network communications are broadcast to the entire network. Bust topology is mainly used in LAN topologies. But today, it is more common in Star topology.


Ring topology

Ring networks run like bus networks with the exception of a terminal. A ring topology is one in which all nodes of the network are linked to a ring. In Ring topology, transmissions pass from one node to the next in an ordered cycle. When the signals reach the last node, they are returned to the first. In Ring topology, there has no beginning or end point because signal is passed in a circular system, using tokens. In Ring, it can also have an ability to bypass any broken or failed node. But, new nodes can be difficult to add because of the closed ring.


Star topology

In Star topology, a LAN network in which each nodes connected to a main device (central) in a star-shaped pattern; mainly, a network consisting of a hub surrounded by workstations (terminals). So, transmissions pass directly from a node to the central computer, which holds any extra routing as to another node. As with the Bus topology with a backbone, the failure of one computer nod论文英语论文网提供整理,提供论文代写英语论文代写代写论文代写英语论文代写留学生论文代写英文论文留学生论文代写相关核心关键词搜索。
