of cables are most commonly used in the network. Currently, more than six types of cables exist. Connect the RJ45 crystal head to the RJ45 socket of the network device, such as the NIC or hub. The RJ45 plug-in seat is also divided into three types or five types of electrical characteristics. RJ45 crystal head consists of metal parts and plastic, making the network cable required RJ 45 crystal connector front end has 8 concave monk, referred to as "se

the line can be connected, but the interference between various lines within the line cannot be effectively eliminated, resulting in an increase in the error rate of signal transmission, this affects the overall network performance. Only by building standards can we ensure the normal operation of the network and facilitate the maintenance work in the future. Connection method between devices 1. When the network card is directly connected to the 10 m or M network card of the network card, the

a large number of invisible fuzzy problems, these problems involving two or more computers of abnormal communication some even involve a variety of protocols, with the help of sniffer% 2C system administrator can easily determine how much traffic belongs to which network protocol, which is the main communication protocol host, which host is the most communication destination, how much time the message is sent, or the transmission interval of each other's host, etc., this information for the adm

(1) New equipment for hub detectionThe host hub monitors the signal voltages of each port and is detectable when new devices are plugged in. (Each of the two signal lines on the hub port has a 15kω drop resistor, and each device has a 1.5kω pull resistor on the d+.) When using a USB cable When the PC and the device are connected, the pull resistance of the device

Message transfer and routing overview Message transfer determines how messages are processed and delivered Message routing refers to the way messages are delivered between servers. To route and transport messages using the server role in the configuration Hub Transport Server Hub Transport servers and edge servers When using only the Hub Transport server, i

Docker+selenium deployment of the Web Automation test environment 1. Open the Docker terminal using SECURECRT or Docker Quickstart terminal. 2. Download the image required for Selemiunui test Command Docker Pull: Download the image from the Docker hub. First, search for the image that needs pull Command:Docker search Selenium For Docker selenium, the image that needs pull here is: Selenium/hub Selenium/no

GSM Modem1) An external modem device, such as the Siemens mc35 or Wavecom fastrack.2) a pc card installed in a laptop, such as the siider wireless aircard 7503) A standard GSM mobile phone with the appropriate cable and software driver to connect to a serial port or U

library net; There is also a team that develops a set of message middleware and provides a client library Hub,hub is Net-based; another team of companies developed a storage system and provided a client library cab, The CAB is also built on net. A service-side program developed within the company may use one or more of these libraries, and this section discusses how to organize libraries and applications d

First, the concept of understanding:1. Conflict domain (physical segmentation):A collection of all workstations connected on the same wire, or a collection of all nodes on the same physical network segment, or a collection of nodes competing for the same bandwidth on the Ethernet. This field represents the area in which the conflict occurs and propagates, and this area can be considered a shared segment. In the OSI model, conflict domains are considered the first layer of concepts, and devices t

USB Introduction: Several versions of USB: 1. USB 1.0: Speed 1.5mb/s 2. USB 1.1: Speed 12mb/s 3. USB 2.0: Speed 60mbb/s 4. USB 3.0: Speed 640mb/s Key Benefits of USB: 1. can be hot-swappable: Do not need to repeat the "shutdown of the same port or serial cable connected to power on again" action. 2. easy to carry. 3. standard Unified, USB mouse, USB hard disk, USB printer are all connected with the same standard with PC. 4. You can co

installation. Run the SoftEther installer...The image quality is a little poor. There is no way to save space.If you think your English is OK, you can tick it. I am not pulling.After the installation is complete, return toOf course. This is roughly the same as the above. Select it by yourself.Next, you will select the services to be installed.Pay attention to pulling. If you only need to create a server, you must select "Install SoftEther virtual hub

. Foreigners call it host controller, another hacker who connects to the Controller is "root Hub". We should be familiar with the hub. In college, some dormitories have limited network ports, however, when our generation went to college, there was basically one computer for each person, so the network port was not enough, so some people would use the hub to allow

. ========================================================== ==================== 1. The vswitch works on the data link layer, and the vro works on the network layer. 2. The vswitch uses the physical address to determine whether to forward data, while the routing uses the addressing method to determine whether to forward data. 3. A vswitch can only be divided into conflicting domains, but cannot be divided into broadcast domains. A route can be divided into broadcast domains. 4. vswitches

processing is required. All hosts connected to the bus constitute a broadcast domain.　　　　 　 Figure 1 Traditional Ethernet 　　　　2. Repeater)　　Repeater appears as a product mainly for two reasons:　　First, expand the network distance and regenerate the attenuation signal.　　Second, Ethernet Interconnection between coarse and fine coaxial cables is realized.　　Although the repeater can extend the signal transmission distance and achieve the interconnection of the two network segmen

In order to save Internet access fees and improve work efficiency, many people share the Internet with multiple computers by using the ADSL routing function. However, if you want to enjoy Internet access through ADSL, you also need to learn the proper adjustment of ADSL from the details. On-demand combination of hardware devices The "match" mentioned here refers to whether the ADSL Broadband modem works with a vswitch or a hub. Although both of them c

topology of network sniffer connected through port Aggregation Currently, some small and medium-sized enterprises only use non-Network-managed switches to build local networks because of their small network size or to save IT costs. For non-Network-managed switches, we cannot use the port aggregation function to access the network sniffer. So what methods should we use for the network environment built by such vswitches to find out the number of network streams in the network, or is it only int

Hub A hub is also called a hub. It works on the physical layer (the lowest layer) and has no matching software system. It is a pure hardware device. A hub is used to connect a computer and other network terminals. The Hub is a shared bandwidth. When any device connected to

The crossover network cable is used for the connection between the adsl modem and the HUB (not all of which are related to the MODEM design). The connection between the HUB and the HUB does not pass the cascade connection port, and the two computers are directly connected to each other through the NIC. The production method is basically the same as the above, but

ADSL is the mainstream form of broadband Internet access. Next we will introduce some maintenance methods that often encounter faults when using ADSL for Internet access, hoping to help you.I. Why is the ADSL indicator normal? The most important indicator of ADSL is "ADSL. When there is no problem with the ADSL line, the light should be green.However, some users will also be disconnected when the "ADSL" indicator is normal, and restart the MODEM. This often happens to network users who do not ha
