FAQs about broadband Internet sharing applications

Source: e Silicon Valley power

Now broadband networks are widely used. In actual use of broadband, the network bandwidth required for browsing web pages, chats, and other applications is not high. For home or small office sites with multiple computers, if you can allow multiple computers to share one broadband account to access the Internet, you can make full use of the network bandwidth, so that more people can enjoy the internet. In addition to shared broadband Internet access, multiple computers can also share multimedia files and printers, as well as multiplayer online games. Next we will give you a simple answer to the frequently-encountered problems in the broadband sharing application process.

　　
Will Internet sharing by multiple computers increase network fees?
　　
Currently, the most common ADSL Internet access method generally uses monthly subscription or hourly billing, and there is no traffic limit. Therefore, data access from multiple computers does not affect Internet access fees. On the contrary, data access fees are saved. However, if you are using the time-based billing method and the automatic dialing method, don't forget to disable the Broadband Router when no bandwidth is used. Otherwise, you will be dumb at the end of the month! In addition, in some regions, the Telecommunications Department may restrict such multiple ways to share one account.
　　
After multiple computers share the Internet, will the network speed slow down?
　　
The speed of Internet sharing depends on the way you use the Internet. The speed of ADSL is generally 512 kbps, but the actual network speed is much lower than this value. For example, if you have four computers, the speed of kbps is the sum of the network bandwidth of the four computers, rather than the bandwidth of kbps for each computer; and, the bandwidth is not necessarily evenly distributed to each computer. For example, when one computer accesses a large amount of data (such as reading and watching movies online), the Internet access speed of other computers slows down significantly.
　　
What methods can I use to share broadband access?
　　
Shared bandwidth is mainly divided into software sharing and hardware sharing. Software sharing is to install shared Internet proxy software such as SyGate and WinGate on the computer connected to the Internet, so that the computer can be used as the Internet server, and other computers can access the Internet through this machine. This sharing method is easy to implement, but it must have a computer with good performance as a server and be started on for a long time. If the computer is not started or fails, other computers cannot access the Internet.
　　
Hardware sharing means that all computers form a local network through switches and other devices, which can communicate with each other and then share the Internet through a Broadband Router. The implementation cost is slightly higher. The configuration is much simpler than the software method, and no server is required. Any computer can access the Internet at any time.
　　
Does Internet sharing have high requirements on computer configuration?
　　
If you use the software-based shared Internet access method, you may be lucky enough to be a server? BR> If the configuration is too low, access to the current data is prone to paralysis. If you use hardware sharing, it has nothing to do with computer configuration, because a Broadband Router acts as a server, and other computers only need to meet the requirements of broadband Internet access.
　　
What is the cost of hardware-based Internet sharing?
　　
If only two computers are shared, the most economical solution is dual-host direct connection, that is, to install two NICs on the computer that serves as the server,
One Network Card is used to connect to the broadband network, and the other network card is connected to the network card of another computer through the Cross network cable, and then the shared Internet software is installed on the server. The price of a common Nic is only about 50 yuan, and the price of the network cable is about 1.2 yuan/meter. Therefore, the cost of purchasing hardware equipment is not high.
　　
If the number of computers exceeds two, in addition to the network cards required for each computer, you also need to purchase a hub, switch or Broadband Router. The price of a low-price hub and switch is between-yuan, the price of a Broadband Router is slightly more expensive. The price of a Common product is between and RMB. If possible, you can also purchase second-hand equipment to reduce costs. In general, it is not costly to purchase hardware devices to achieve shared bandwidth, which can be borne by ordinary households. If economic conditions permit, you can select a Broadband Router.
　　
How can broadband Internet access Ensure network security?
　　
Many of my friends are worried about Internet access through shared bandwidth, and their machines will be hacked ". In fact, in general, if you use the software sharing method, because the current shared software has a relatively powerful function, generally has the firewall function, when the outside world uses the connection LAN, because the LAN has only one valid IP address, even if it is connected to the Internet, it only connects to the shared server. Other internal computers cannot be accessed, so they cannot be intruded.
　　
The same is true for hardware sharing. Many broadband routers also have firewall functions, so the external connection is the vro itself, and the vast majority of hackers will not be able to work after encountering vro attacks, therefore, the security is higher, because the vro itself is not afraid of attacks. Therefore, although you can rest assured that you will not be hacked!
