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

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.

. 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.
