First, connect our computers to the network. When the connection is successful, click on the network icon in the lower-left corner of the desktop and choose Open Network and Sharing Center. After entering the network share center, enter the network connection interface of the Control Panel, then click the Network icon between the computer and the Internet.

Under the Windows 7 system, because of the security restrictions, this machine built the site, the local area network other computers are inaccessible. To solve this problem, just add a custom rule to the firewall, as follows: Control Panel =>windows Firewall => Click on the left advanced settings to eject the Advanced Windows Firewall window => Click on the left inbound rule, then click on the right to create a new rule, pop-up New Inbound Rule

Whether it's a computer, a smartphone, or any other networked device, connecting to a network means you're already exposed to a security threat. In recent years, in particular, the rapid development of spyware and various kinds of spy tools has led to the increasing efficiency of hacker organizations and intelligence agencies in stealing intelligence. Now the question is: if the computer, mobile phones are broken network, will also be hacked? Computer experts with a strong sense of

crashes, so mobile computers should avoid violent vibration. "Dust Killer" Too much dust in the machine can cause a panic failure. such as floppy disk head or optical drive laser head contaminated with too much dust, will lead to read and write errors, serious will cause computer crashes. "Device Mismatch" such as motherboard frequency and CPU frequency mismatch, the old motherboard overclocking will FSB set too high, may not guarantee the stab

In fact, find some computer configuration of the site is very easy, in Baidu to find "Computer Configuration Network" that can appear about the configuration of the computer site, as shown in the picture: Find some of the information you need in these sites, and then look at other people's model computers, and other people's comments, you can learn a lot about configuring computers. After you have

Today, when privacy is so important, we don't want our computers to be used by others, especially if we are unaware of it. So let's learn how to prohibit others from logging into their computers in the Win7 system. Step one: First, open the Win7 flagship version of the Start menu, and then click into the Control Panel, and then in the control Panel into the account settings interface. Step two: Unl

patiently. We can quickly understand and grasp each new feature of Windows7. If you have just started a new Win7 computer, so there's a lot of important information on the old computer that might need to be transferred to a new computer, and then open the Windows Easy Transfer tool, which can help users quickly copy user files and settings from old computers (old systems) to new computers (new systems)

appropriate link to send it to the next node according to the address information in the packet header. In this way, the bandwidth can be allocated dynamically according to the requirements of the user and the ability of the network in the communication process. Packet switching is more efficient than circuit-switched channel, but has a large delay. The problem with packet forwarding: queuing delay and increasing the overhead associated with the head. In short, if the amount of data to be tran

Electronic computers can process information and processing at very high speeds, including data processing and processing, and have a great capacity for storing data. Data in the computer in the physical state of the device, using a binary digital system, the computer processing all the characters or symbols to be represented by a binary code. The advantage of binary is that it is easy to express, the operation rules are simple and the equipment is s
