grid. Seleniumgrid is a cluster that has a central node, called a hub, and multiple execution nodes, called node. The role of the hub is to manage nodes (such as node information, whether alive), establish a connection with the client, and send execution commands to each node. The demarcation point between the client and the hub is driver here. That is, the sele

The network card has 10m,10m/100m,100m,1000m. Network cable has 3 categories (10M), 5 class (100M), Super 5 type Line (155M), 6 class line (255M). The network card has 10m,10m/100m,100m,1000m. Network cable has 3 categories (10M), 5 class (100M), Super 5 type Line (155M), 6 class line (255M) respectively corresponding to the different network cards and speed, now generally the lowest use of 5 lines. They all have the same network cable practices. Network device

Method one, before making network cable, need to prepare several kind of tool. 1, with 8P Groove crimping pliers One. 2, five types of network cable, which is now the most commonly used network cable several meters. 3, RJ-45 plug, which is known as the number of crystal head. PS: In theory, the crystal head only needs 2, just in case, more prepared. Method one, the wire standard line order: Standard 568a:1 Green white, 2 green, 3 orange white

However, the use of the diagnostic package requires a license. 2. enhancements to the grid (gridinfrastructure) a

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

At present, there are usually a certain number of enterprises, basically in other regions there are some branches, factories, offices and other institutions, how to efficiently, securely, and cheaply connect the networks of these branches to the Headquarters network has become an obstacle for enterprise informatization. This article introduces a Simple and Easy VPN connection technology to help enterprises solve this problem. I. Case studies A large enterprise is distributed all over the world.

The OSI Layer-7 model enables reliable communication between different networks of different systems through seven hierarchical structural models. Therefore, its most basic function is to help different types of hosts transmit data. The node that completes the relay function is usually called a relay system. In the OSI Layer-7 model, the relay systems at different layers have different names. The layer at which a device works depends on the Data header information used during its operation. Whe

types of lines, and over five types of lines. Currently, there are more than six types of lines. The third type of twisted pair wires are commonly used as 10 Mbps Ethernet data and voice transmission in the LAN, which complies with the IEEE 802.3 10Base-T standard. TheCat5e twisted pair wiresThe largest LAN market, with a maximum rate of 100 Mbps, complies with the BASE-T standard.

At present, many small and medium-sized enterprises have similarities in their network environments. If the network quality is not good, there will often be chaos. I have experienced such a thing. The network of the organization where the author is located is like this: a network cable + an ADSL Router + A multi-port Hub, and several shared Internet PCs are connected to the Hub. Due to the increasing number

more than one NIC in one of the computers. In this configuration, there are often several specific shared scenarios. Here we subdivide two main solutions, one is no need for any hub devices, that is, without hubs and switches, simply through the network card to achieve the interconnection of three computers. Another scenario we'll mention later. The equipment required for the previous programme is as follows: • 5 block 10/100mbps Ethernet card (one

.2. General line network: The main feature of the bus structure is "a common network cable to connect all the computers," this very long line is a "lot of short" cable to connect. It has the advantages of low cost and simple wiring. As long as you buy enough cable, connectors, network cards, you do not need additional network equipment. But there are many disadvantages, first of all, as long as the network of any line failure, the entire network is paralyzed, and "trouble shooting" is a very tro

released on February 12, 2013 to support the SP3 installed under Windows Server 2012, Enterprise users can download as needed. This series of articles will take the Exchange Server SP1/SP2 as an example, starting with an understanding of the Exchange Server 2010 architecture, to introduce its deployment, role configuration management, mail \ Mailbox Management, backup recovery, high availability, and exchange migration. Let's take a look at the architecture of the Exchange Server2010 first. E

hubs and switches. The Hub does not have a connection concept. Therefore, each packet received from a port will be copied to another port. However, a vswitch is connected. When a data packet enters from a temporary connection port of the vswitch, the data packet is forwarded to the destination port. Therefore, in a hub environment, we can place our detectors in any location, but for a switch, we must use s
