1、家庭、小型办公室、局域网的组建（Home, small office, LAN construction）A home or small office, if there are two or more computers, they will naturally want to form a network. For the convenience of narration, the following conventions will be referred to as lan. In the family environment, can use this network to shar
2、e the resources, those who need to play multiplayer games, sharing a modem and enjoy Internet connections and so on. In the office, the use of such networks, mainly to solve the shared peripherals such as printers and etc. in addition, the infrastructure is office LAN multiplayer collaboration work.
3、Dont look at such a small AP network engineering, in the past also need professional network configuration. At that time, most of the operations are manual, general users do not have the corresponding knowledge and experience. It belongs to the underachievement, natural limits its development. Windo
4、ws XP, broke the situation that has powerful network functions and convenient guide to build it in. The user completes the physical connection, run the connection wizard, can detect the network hardware, install the corresponding driver or agreement, and guides the user to complete all the steps of
5、the configuration.This paper introduces two kinds of the brand networking scheme in Windows XP operating system, and introduces the Windows XP for a variety of very unique features in the lan.Which was a target:Improving the composition of the family: foreign lan, can be connected to the Internet, a
6、llowing each computer in the LAN connection sharing. On the inside, can share the cyber source and equipment.Which was two. What is the network form?Improving the family network computer may have a desktop or laptop, such as handheld computer or notebook, may also appear in a variety of transmission
7、 media interface, so the network form, should not use a wired network, the wireless interface must be taken into consideration. But if you can clear positioning in the purely wired network, or not to set up a wireless interface. So, here are two kinds of schemes:AP 1. wired and wireless hybrid.AP 2.
8、 cable.Three. Improving the network hardware choiceImproving the network adapter (card) can use PCI, PC or PCMCIA interface card (which is used in portable computer or notebook computer), Windows XP also supports network adapter with USB interface. What kind of the adapter, depending on the access n
9、etwork computer. No matter what kind of adapter, all need to pay attention to with the existing computer interface and the HUB coordinated USB adapter might be more adaptable, but for older computers, they need to pay attention to whether it supports USB interface.Improving the network connection li
10、ne, commonly used with coaxial cable and twisted pair, this is the familiar things, not much to explain. What is what kind of, to see how you like it.Four. The network structure and the medium can be usedImproving the etheric structure: the structure in the office or business users in the most popul
11、ar, but also a lot of familiar people, technical data and maintenance personnel are easy to find, so much repeat.Improving the telephone line connection: this form is the main characteristics of low cost, physical connection is also very simple, suitable for most home users.AP: radio waves to transm
12、it signals by using electromagnetic wave signal, without any connection to communicate, and can be used in mobile. But you need to install the wireless adapter on each computer, the high cost is affirmed. In our country, with less in the form of wireless computer network communication. In the United
13、 States, for the wireless network is a standard protocol called IEEE 802.11b, for short distance communication network computer. Supported by the protocol, can reach the speed of 11 Mbps.Which was one of the five schemes.AP this is a wired and wireless hybrid scheme, the concrete structure can be fo
14、und in figure 1. In this example, use 4 computers to form a hybrid network, PC1 is the host, it has 3 channels and the external connection:Which was 1. and Internet series of modem: for Internet users sharing each computer across the network.AP: 2. wireless adapter for communication between the wire
15、less device and the network.Which was 3. HUB for driven in the network downstream of the computer.PC1 PC2, which was in the scheme, must use the Windows XP operating system, the wired part adopts Ethernet connection structure. Figure HPNA home phoneline network is the abbreviation of adaptor home ph
16、oneline network adapter. Figure PC3 and mobile computer, does not require not use the Windows XP operating system, other versions of windows line. The connection between the mobile computer and the host network is wireless form.If you want to build a mixed network, this scheme has the typical functi
17、on, and do not need to spend a lot to expand the network size.A connected operation:Figure 1 shows the structure of the brand can only represent the physical connection, the physical connection is completed, but also the need for network connectivity operation, can be put into use. Connected operati
18、on including connectivity between each internal LAN computer, and communication between LAN and Internet. The former is established as follows:AP 1. mouse click start, go to control panel, click on the Network and Internet Connections and Internet network connection, network connection (Network Conn
19、ections), the next step.AP 2. chose connecting two or more LANAP 3. right click on a link.4. which was determined to complete the connection.The operation of the brand communication within the LAN is completed.Besides improving the communication between LAN and Internet, which mainly consider two as
20、pects of speed and cost. For the Internet, the most convenient way is to each machine occupy an independent phone line, but this is not the general user can afford the waste of resources is too big. Another way, you can use the residential gateway, but this is not the best way to increase the cost.
21、A better method is to use a computer as a host server. This is not only technically feasible, and many other advantages, such as:AP: because Windows XP has a built-in firewall between the host between Internet and terminal, can use a firewall to protect LAN host in the extension from the attack from
22、 the Internet.AP: the host is hidden in between Internet and LAN, acts as a gateway role in the extension, users feel like they are directly connected to the Interne, not aware there exists the host. Especially at the same time the Internet can make each computer in the lan. Reduce equipment investm
23、ent.AP: in addition to the host must use the Windows XP operating system, LAN computer can use earlier versions of windows.AP: if the use of different media to LAN (such as wired and wireless hybrid), you can use the Windows XP as the bridge of transition.AP 5: although sharing cyber source and equi
24、pment, but also can restrict others to private files and data access, especially when the files are stored in the host, this advantage is more available.The use of the brand: universal plug and play function, can expand the scale of local area network.Which was six. Two of the planThe brand below is
25、 a schematic structure of this scheme. The scheme is suitable for small office. Compared with the previous schemes, the main is to remove the wireless part, not by telephone line connection between host and extension, instead of using a cable or twisted pair connection. All branches are connected to
26、 the Internet through a HUB with the host, and can support the printer sharing. In fact, this kind of network is the most common structure.After the program to complete the physical connection, also need to carry out the following operations:Which was 1. to open the Network Connections folder icon o
27、r network connection.AP 2. right click on the connection to the Internet you want to share (shared Internet connection) and then right click on the Properties (attribute)AP 3. select Advanced (Advanced) task.The brand Allow other network users 4. to connect through this computer s Internet connectio
28、n (also allows users to connect to the Internet through the computer) check box, and select.Which was 5. OK. click on the end of operation.Which was to enable the Windows XP firewall, you must set up, do not set is not effective. Set up process:Which was 1. to open the Network Connections folder ico
29、n or network connection.AP 2. right click on the connection to the Internet you want to share (shared Internet connection) and then right click on the Properties (attribute)AP 3. select Advanced (Advanced) task.The brand Protect my computer and 4. network by limiting or preventing access to this com
30、puter from the Internet (using the computer from the Internet into the restricted access and protect my computer and network, in the following a Internet connection firewall check box, click the mouse.Which was 5. OK. click on the end of operation.Which was seven points.The brand A. host must use Wi
31、ndows XP operating system, LAN computer can use earlier versions of windows,Such as: Windows98, windows, ME, Windows2000 and so on.The B. here is the typical situation, to expand the network size can be basically according to the superposition.This paper is the experimental basis for improving the C
32、. English test version of the official version, can not guarantee the future. Especially the performance of the official version of Chinese was consistent with this.Reference: http:/ LAN and configuration managementA concept:(a) the concept of LAN:As part of the local network, play a role can not be
33、 ignored. We can use Windows 9X to large computer linked to the formation of a LAN, in the LAN, we can share programs, documents and other resources between them, instead of passing back and forth floppy disks; can also through the network computers to share the same hardware, such as printers, mode
34、ms, etc.; at the same time, we can use a computer network to send and receive faxes, convenient and economical.AP LAN is a range of big and small, simple operation with only 2 Taiwan computer networking Windows95 (to work group), can also be a large enterprise vast high-speed ATM network and Etherne
35、t mixed use, multi platform operation.(two) the type of network:1, according to the network location classificationA. LAN (LAN): generally defined in a small area, less than 10km, is usually used to connect cableThe brand B. metropolitan area network (MAN): the scope of a city scale in the region of
36、 10 to 100km.C. wide area network (WAN) network across borders and continents, and even the world.At present, LAN and WAN is the hot spot of the network. The LAN is composed of two other types of network, metropolitan area network generally joined wan. A typical representative of the wide area netwo
37、rk is Internet network.(two) Hardware Guide: network hardware.The main hardware components of small LAN equipment network card, network transmission medium and hub repeaters, bridges, routers, gateways and other network interconnection. The following mainly introduces network card, network transmiss
38、ion medium and hub repeaters, bridges, routers, gateways and other LAN interconnection equipment.AP 1. cardNIC (Network Interface Card, NIC) is also called the network adapter is connected to the computer and network hardware. The card is inserted in the expansion slot of computer or server, through
39、 the network line (such as twisted pair, coaxial cable or fiber) data exchange, resource sharing and network.This is Realtek 10/100M, we use examples in the cardTwo: return to the top network.(a). Hardware configuration: Server: PC, motherboard: Intel 815, CPU:PIII933, 40G: Maxtor hard disk, memory:
40、 512M, display: ACER.Other: a box of twisted pair (300m), a 16 HUB RJ45, the head of the 32, card: Realtek 10/100M 16 block.Which was due to the server needed to maintain management with SyGate installed two pieces of card, please refer to the following animation two card set.Network maintenance: re
41、turn to the top three.Which was the SyGate 4 is a support for multiple users to access the Internet software, and it is only through a computer, sharing the internet account, to achieve the purpose of internet. The use of SyGate 4, a number of users at the same time through a small network (includin
42、g your notebook computer), rapid, efficient and economic access to the internet. SyGate 4 in the current operating system running on many popular, such as: Windows95, Windows98, Windows, NT, Windows2000 and other operating system; at the same time, SyGate 4 also supports most of the Internet connect
43、ion, which includes: a modem (analog circuit), dial ISDN (Integrated Services Digital Network), cable modem (Cable Modem) ADSL, DirectPC, etc.The SyGate 4 has the following advantages:Which was easy to install SyGate in a few minutes can be installed, and usually do not need other additional setting
44、s. And other proxy server software (proxy server) is different, SyGate can only install Server.Which was easy to use SyGate with intuitive graphical user interfaces, understand the operation of Windows personnel can operate. SyGate will start running in the background, without manual intervention. W
45、hen the SyGate detects the LAN access request, it can automatically connect to the Internet, not every time need to manually dial trouble. The user can continuously and transparently browse the Internet, e-mail, chat, the use of FTP and the operation of other small programs etc. Local non Windows us
46、ers, such as Macintosh, Solaris and Linux, were able to access through the TCP/IP protocol.Four.Windows peer to peer network creation and maintenance of return to the top(a) networking software requirements.In a local area network, Windows 95, 98, NT and 2000 other operating system can coexist. Of c
47、ourse, even if your computer is running under DOS, but also can achieve network. Because the Windows operating system is widely used in the system, not ready to discuss the DOS network.Network hardware requirementsTo set up the computer network, the computer will undoubtedly need to together hardwar
48、e equipment. The easiest way is to use special cables, two computer parallel port or serial port connected via Windows direct cable connection network. The cable connection can be made, can also go to the city to buy a computer. The disadvantage is that only two computer network connection, the traditional way of short distance, and the actual application is not convenient, will typically require a computer as a server, the other one is used as a client to achieve networking.Bu
