Use the following DNS server address preferred: 1.1.1.1, and finally click OK. 　　Second, bro

new module and the old module have the same functions and interfaces, even if they use different algorithms and protocols. To transmit information and data correctly between computers and terminals in the network, there must be an agreement or rule on the order of data transmission, data format and content, such an agreement or rule is called an agreement. The network protocol consists of three parts: 1. Semantics:

people call it very well.Some people also say that layer-3 switching is nothing new than the stacking of routers and layer-2 switches.Is that true? Next, let's take a look at the working process of a layer-3 Switch through a simple network. Easy networking Device A using IP ---------------------- layer-3 Switch ---------------------- using IPDevice B For example, if A wants to send data to B and the destination IP address

Multi-layer switching (also known as layer-3 switching technology or IP address switching technology) is proposed in contrast to the traditional concept of switching. As we all know, the traditional exchange technology operates on the data link layer, the second layer of the OSI network standard model, and the multi-layer exchange technology implements high-speed packet forwarding in the network model. To put it simply, the multi-layer exchange techno

dialing between your machine and the ADSL terminal, so the local connection is restricted or connectionless without affecting the normal use of this virtual circuit (of course, virtual circuit running on the real circuit, your network card, ADSL modem and the local ADSL access device must first establish a physical connection to make this virtual circuit work, except the physical connection in the software system does not have to allocate the corresp

The following figure: The above DNS server address to fill in the correct general can open the Web page, the general our computer is the choice of automatic access to IP router allocation and automatic access to the Network service provider DNS, but because of the need to fixed IP to solve the computer boot local connection is slow and so on, you need to set up DNS,

Photoshop any layer cannot be moved or modified, prompting the target channel to be hidden.Any layer in PS cannot be moved and cannot be modified with the eraser tool, prompting the target channel to be hidden. I saw a quick mask layer inside the channel (and it was hidden), I opened the mask layer, the image processing area has a red cover, always can't move I want to move, can only move this red cover.

to each computer connected to the router, and without an IP address, of course, you will not be able to access the network (when the IP address is automatically acquired, you will also need to allocate IP), you can do the following: Right-click "Local Area Connection"--pop-up window Select "Properties"--Double click Internet Protocol (TCP/IP), check the Internet Protocol properties on the pop-up page of the use of the following IP address, manually

three: Locate the local connection, right-click and select Properties. As shown in the following illustration: Step Fourth: Locate and click Internet Protocol version 4 (TCP/IPV4) and click Properties. As shown in the following illustration: Step Fifth: Choose to use the following IP address (S); Set IP address to 192.168.1.10, subnet mask to 255.255 255.0, Gateway 192.168.1.1, cl

1) The Internet, from the literal meaning of disassembly, is that interconnected network, to be supported by computers and networks.2) computers are familiar with the office, entertainment, audio and video of a tool, is a great invention for the benefit of mankind.3) network-related is the switch, router, domain name, IP address and so onSwitch: Implements data e

In the same LAN, in order to facilitate resource sharing and downloading, it is necessary to establish a network share folder. However, when a network share folder is successfully established, it is not possible to ensure that every user on the LAN can successfully access and log on to the shared folder. So how do you solve this problem for Win7 64-bit flagship I

wireless AP's maximum coverage distance can reach 400 meters. The extended AP is what we often call a wireless router. Wireless routers, as the name implies is a wireless coverage of the router, it is mainly used for users to the Internet and wireless coverage. Through the routing function, we can realize the sharing
