Detailed explanation of cable connector
A lan is to connect individual computers or terminals using networks to exchange information and share resources according to certain protocols. Commonly used network cables include twisted pair wires, coaxial cables, and optical fiber cables. Twisted Pair wires can be divided into shielded twisted pair wires (STP) and unshielded twisted pair wires (UTP) based on whether they are added with the screen layer of a wire mesh ). Most local networks use unshiel

A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more upscale a router has more interface types, because the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration ports.1. LAN interface
Common Ethernet interfaces include AUI, BNC and RJ-45 interfaces, as

The company has determined the model as Dell Elastic Compute service 7370.And the Dell poweredge 5050 SFF. The laptop has canceled the traditional
RJ45-type network cable plug, also known as Crystal Head, is widely used in LAN and ADSL broadband Internet users of network equipment between networks (called five-type line or twisted pair) connection. In specific applications, RJ45 plugs and network cables have two connection methods (line order), respectively called T568A Line sequence (Fig 1) and t568b line sequence (Figure 2).
The market demand for Cisco routers has been very high. Here we mainly analyze the detailed knowledge of Cisco router configuration and RJ45 console connection, for accessing and configuring I0S on a new router, we must communicate with the Console port.
After connecting a console terminal with the Console port configured by the Cisco router, you can start to communicate with the router. This type of terminal can be a non-intelligent ASCII terminal, s
Vro interfaces are very important for network connection and routing functions. Here we will give a comprehensive explanation of vro interfaces and connection knowledge. A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more high-end router interfaces there are, the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration

The module can be used on both the Panel and distribution frame.
Based on years of experience, IBM has found that in the Integrated Wiring System, due to the constant changes in customer requirements, there are often some deviations between design and construction, especially some major projects, these results in a waste of time and cost for the entire project. If some structured de
For the router connection, I believe many people are aware of, the following mainly for the router hardware connectivity issues, a comprehensive introduction. The application of the router is very broad, it has the type of port is generally more, they are used for their different router connection, if you can not understand the role of the respective ports is likely to make the wrong connection, resulting in incorrect network connectivity, network. 1. Connection between router and LAN access d
not have input and terminal display devices, but it needs to make the necessary configuration to normal use, so the general router with a control port "console" to connect with the computer or terminal equipment, through specific software for the configuration of the router. Let's take a look at the router's LAN and WAN connection ports first.
1. LAN interface
According to the name of its interface, we can see that these interfaces are mainly used for routers and LAN connection, because the L
certain share of the market at a low price. However, due to the low network transmission rate of the 10 Mbps ISA plug-in Nic and occupying a large amount of CPU resources, only applicable to LAN with low speed requirements. Therefore, we recommend that you use a 100 Mbps PCI plug-in or a 10 Mbps/Mbps adaptive Nic, Which is inexpensive and can be adapted to a large number of users, an application environment that transfers large amounts of data online and requires multimedia information.

only used in the most basic 10Base-T Ethernet network, but also in the mainstream 100Base-TX Fast Ethernet and 1000Base-TX Gigabit Ethernet. Although the transmission media they use are of the twisted pair type, they use different versions of the twisted pair type, for example, for the first 10 BASE-T to 6 categories that support BASE-TX gigabit speed, the 100Base-TX in the middle uses the so-called five-category and cat-5e lines. Of course, it can also be six categories. These RJ-45 interfaces

VroInLanThere are many types of LAN interfaces to match different routes, such as the AUI port and SC port. LAN interfaces are mainly used to connect routers and local area networks. Because there are also a variety of LAN types, this determines the LAN interface types of routers.
Different networks have different LAN interface types, common Ethernet interfaces include AUI, BNC and RJ-45 interfaces, as well

It is used not only in the most basic 10base-t Ethernet networks, but also in the current mainstream 100BASE-TX Fast Ethernet and 1000BASE-TX Gigabit Ethernet. Although the transmission media they use are twisted-pair types, but they used different versions of twisted-pair types, such as the 3 line used initially by 10BASE-T to support the 6-class line of 1000BASE-TX gigabit, and the middle 100base-tx to use the so-called

It is mainly used together with the 25/50/100 pairs of large logarithm cables. Its disadvantage is that it is troublesome to connect t

Therefore, we choose to have the electromagnetic protection of super five type shielded twisted pair. (Figure 1) 3. Su

In fact, Cisco does not take a special advantage in the low-end switch market, because 3Com, Dlink and other companies have better performance and price ratios. The 1900 vswitch is a typical low-end product for desktop computer access at the end of the network. It provides 12 or 24 10 M ports and 2 100 M ports. The 100 M port supports full-duplex communica
