Network Devices
TextThere are many types of media for the network, and each one has advantages and disadvantages. One of the disadvantages of the type of cable that we primarily use (CAT5 UTP) is cable length. The maximum length for UTP cable in a network is 100 meters (approximately 333 feet). If we need to extend our network beyond that limit, we must add a device to our network. This device is called a repeater.The term repeater comes from the early days of visual communication, when a man situated on a hill would repeat the signal to the person on the hill to his right. It also comes from telegraph, telephone, microwave, and optical communications, all of which use repeaters to strengthen their signals over long distances, or else the signals will eventually fade or die out.The purpose of a repeater is regenerate and retime network signals at the bit level to allow them to travel a longer distance on the media. Watch out for the Four Repeater Rule for 10Mbps Ethernet, also known as the 5-4-3 Rule, when extending LAN segments. This rule states that you can connect five network segments end-to-end using four repeaters but only three segments can have hosts (computers) on them.The term repeater traditionally meant a single port in and a single port out device. But in common terminology today the term multiport repeater is often used as well. Repeaters are classified as Layer 1 devices in the OSI model, because they act only on the bit level and look at no other information. The symbol for repeaters is not standardized.The purpose of a hub is to regenerate and retime network signals. This is done at the bit level to a large number of hosts (e.g.4,8, or even 24) using a process known as concentration. You will notice that this definition is very similar to the repeater’s, which is why a hub is also known as a multi-port repeater. The difference is the number of cables that connect to the device. Two reasons for using hubs are to create a central connection point for the wiring media, and increase the reliability of the network. The reliability of the network is increased by allowing any single cable to fail without disrupting the entire network. This differs from the bus topology where having one cable fail will disrupt the entire network. Hubs are considered Layer 1 devices because they only regenerate the signal and broadcast it out all of their ports (network connections).

那里的网络设备正文是网络的媒介的很多类型,并且每一个有利弊。 我们主要使用的这类型电报(CAT5 UTP)的缺点之一是电报长度。 用一个网络的UTP电缆的最大长度是100米(大约333英尺)。 我们需要延长我们网络在那以外限制如果,我们必须给我们网络添加一个设备。 这个设备被叫为一台中继器
术语中继器来自直观通信的天的早些时候, 当一个位于一座小山的人将对他的右边在小山对人重复信号时。 它也来自电报,电话,微波和光通信, 其全部使用中继器加强越过长距离的他们的信号,要不然信号将最终消失或者消失。
一中继器的目的再生和retime 网络信号在允许他们旅行长距离在媒介上的一点儿水平。 当延长局域网部分时,留意4 个中继器10也是被称为5-4-3规章的Mbps Ethernet的规章。 这规章说明你能连结5 网络段...

有许多类型的媒体的网络,而且每一个优点和缺点。对的电缆类型的缺点之一,我们主要使用(5类双绞线)的电缆长度。对UTP电缆网络中的最大长度为100米(约333英尺)。如果我们需要限制超出我们的网络,我们必须将设备添加到我们的网络。这个装置被称为中继。

一个再生中继器的目的是和在位水平回复时间的网络信号,让他们的旅行对媒体较长的距离。当心四个转发规则为10Mbps以太网,也称为5-4-3规则扩展LAN网段时,已知的。这条规则规定,可以连接5个网段结束对终端使用,但只有4个中继器可...
