First of all, if you don’t use a mobile hard disk, you need to set up a LAN and then share files. The method to set up a LAN is as follows: Everyone knows that the biggest feature of a LAN is that it can achieve the best utilization of resources, such as:*** Sharing disk devices, printers, etc., so that files can be called to each other within the established LAN and printed on any shared printer; of course, we can also use software such as Wingate or Sygate to share one file on multiple machines. Use a Modem to access the Internet; or connect to the Internet through a proxy server to enjoy extraordinary speeds. If you have more than one computer at home, and if you want to upgrade your computer game room to an Internet cafe, then you have to consider connecting them into a LAN.
Don’t think it is difficult. In fact, if we just set up a small local area network, we only need to buy a few network cards and some data cables, and we can have enough food and clothing by ourselves. We know that Windows98 has built-in point-to-point (pc to pc) network configuration capabilities, which makes it easy to establish a small network. If your LAN has many computers, then you need a mature network operating system to manage the network, such as Windows NT, Novell Netware or Linux, etc.
If you just want to connect two PCs equipped with Windows series operating systems, we can directly connect the two PCs through the computer's serial and parallel ports and use serial and parallel communication cables (pc to pc). After the computer is connected, select Microsoft's "Dial-up Network Adapter" in "Adapters" under "Control Panel/Network" in Windows and "IPX/SPX Compatible Protocol" and "NetBEUI Protocol" in "Protocols". Then start the "Control Panel", select "Add/Remove Programs", click "Install Windows Programs", select "Communications", click "Direct Cable Connection", and then use the Windows installation disk to install. After installation, restart your computer. Select a computer as the host, right-click a drive (such as C drive) in the host's "My Computer", select "Maximum Sharing", and select the mass sharing level. Run "Direct Cable Connection" in the accessories of both machines, and on the host machine, select the communication port used. Select another computer as the client, follow the prompts, wait a moment, and the connection is completed. Open "Network Neighborhood" on the "Client" desktop, and you will find that you are no longer alone. You can access your host through "Network Neighborhood", or you can map the network drive to yourself through the "Map Network Drive" method. Virtual physical drive, what's even better is that if the host you are connected to is already on the LAN, then you can also access all online resources through the host. And when you visit, it does not affect the normal work of the host, which is especially beneficial to laptop users.
When there are more than two computers (PC), network cards, network cables and hubs (HUB) are needed.
If there is no network card in the LAN, it is like a river without bridges on both sides. Network card is the abbreviation of NIC (NETWORK Interface Card), which is one of the most basic components of a local area network. The network card is installed in the expansion slot of network computers and servers and serves as the physical interface between the computer and the network. Therefore, it can simply be said that the network card is a bridge for receiving and transmitting data. According to the transmission rate, network cards can be divided into: 10Mbps network card (ISA socket or PCI socket), 100Mbps PCI socket network card, 10Mbps/100Mbps adaptive network card and Gigabit network card. At present, the 10Mbps ISA socket network card still occupies a certain market share with its low price. However, due to the low network transmission rate of the 10Mbps ISA socket network card and occupying a large amount of CPU resources, it is only suitable for those LANs that do not have high speed requirements. I recommend using a 100Mbps PCI socket network card or a 10Mbps/100Mbps adaptive network card. It is not expensive and can be adapted to application environments with a large number of users, large amounts of data transmitted on the Internet, and multimedia information transmission.
When choosing a network cable, you must first look at the interface type of the network card you purchased. There are two types of network card interfaces: RJ45 port and BNC port
The BNC port uses a thin coaxial Cable serves as a network card interface for transmission media. RJ45 is a network card interface that uses twisted pair cable as the transmission medium. The interface of RJ45 is similar to the interface of a telephone line, but the network cable uses an 8-core connector. The disadvantage of using RJ45 is that the installation cost is high, but installation and maintenance are more convenient. , so we generally use the RJ45 interface. Hub (HUB): Depending on the number of microcomputers, the HUB is used to form a star structure. When there are many workstations, the processing rate of the HUB is far lower than the transmission speed of the communication line, causing a bottleneck problem. Therefore, you can choose a switch if possible.
The domain composed of a Hub is called a conflict domain. That is to say, when any computer on the network sends and receives data, all other computers can receive it, and these computers cannot send and receive data at the same time, otherwise a collision will occur (CSMA /CD protocol prevents collisions). In addition, each computer connected to the Hub must detect the destination address of the received data to confirm whether it has received its own communication information. Therefore, the computer CPU usage is high and the overall network communication efficiency is low. It is only suitable for small workgroup levels. application.
The functions of a hub (HUB) are:
(1) Each twisted pair interface is only connected to one workstation (network card), and signals are transmitted point-to-point.
(2) When a certain port receives a signal, HUB will reshape it and broadcast it to every other port.
(3) HUB itself can automatically detect signal collisions and send out signals immediately when collisions occur. The blocking (jam) signal notifies other ports.
(4) When the transmission line or network card of a certain port fails, the HUB automatically isolates the port so that it does not affect the normal operation of other ports. Since the 100M hub is relatively small Expensive, we usually choose a 100Mbps network card and a 10M hub, and later upgrade to a 100M hub as needed.
OK! The components required for the LAN are all ready. Now let me follow you step by step to set up a LAN bar based on Windows2000 Professional, the most stable personal operating system at the moment.
