1.Network card Network card can be divided into three types according to the type of connector: AUI, BNC and RJ45 connector, which are used to connect three different network cables, namely AUI cable and RG-58A U electric twisted pair cable [including unshielded cable (UTP) and screen twisted pair (STP)]. AUI connectors and cables, due to the troublesome wiring construction, have been eliminated from the market, I will not describe in detail.
The use of BNC connectors and RG-58A U network cables to construct the network is not only the most inexpensive, but also easy to install, so it is favored by DIY people. The RJ-45 connector is used to connect twisted pair cables, and is also widely used because of its easy expansion and convenient system debugging.
The network card can be divided into four types: PCI, EISA, PCI, and SISC in the form of bus. It can also be used according to the data transmission bandwidth of 10m s, 100m s, 10m-100m, 100m network card, and the more used is 10m-100m adaptive network card.
2.The type of network.
Generally speaking, LAN topologies can be roughly divided into bus, star, and ring networks.
The bus structure uses a common network cable (usually a thin cable) to connect all computers. It has the advantage of low cost and simple wiring, but there is a fatal disadvantage that if any node of the entire network fails, the entire network will be paralyzed. This topology is gradually being phased out.
Computers with less than 10 computers are more suitable for bus-type networking, and more than 10 computers are troublesome to maintain and prone to failure.
A star is when all computers are connected to a hub (or switch, router, etc.), through which signals are passed between the computers. Its advantage is that the local line failure of the network will only affect the local area, and will not cause the entire network to be paralyzed, which is convenient for maintenance. The disadvantage is that the cost is higher (relatively speaking).
As you can see from the above, the bus type does not use a hub, while the star type needs at least one hub to make the network work, thus increasing this part of the cost. Star networking is more popular, and it is suitable for any computer networking.
The ring structure is only used by IBM, and it is rarely used at present, and it is not considered to be the trend of the future.

1. First of all, to establish a local area network, there must be two or more computers, and connect the computer and router to be connected with network cables.
2. Right-click on the network connection on the far right of the computer desktop to enter the network and sharing center.
3. Find the Advanced Sharing Settings option in the interface and click it.
4. After that, select the sharing settings according to the situation in the interface, whether it is a family or a company.
5. Click the Save Modification option in the interface.
6. Then select the folder or drive you want to share. Right-click on the property.
7. Click on the advanced sharing option in the interface.
The main steps in forming a domain network.
The steps are as follows: 1. First of all, to establish a local area network, there must be two or more computers, and connect the computer and router to be connected with a network cable. 2. Right-click on the rightmost network connection of the electrolift hungry brain desktop to enter the network and sharing center.
3. Find the Advanced Sharing Settings option in the interface and click it. 4. After that, select the sharing settings according to the situation in the interface, whether it is a family or a company. 5. Click the Save Modification option in the interface.
6. Then select the folder or drive you want to share. Right-click on the property. 7. Click on the advanced pants to take the sharing option in the interface.
Add domain users.
Go to the DC and the controller server to add it.
Yours is connected to the switch with 4 ADSL routers, and then connected to the PC bar below, so that it is in a local area network, and then it is not in a network segment of the local area network. >>>More
Computer supporting: computer desk, computer chair.
Wiring needs: network cable (according to the size and distance of your computer room to determine the length, generally a computer room two boxes of wires are needed, 400 hundred meters), switch cabinet (50 machines of 1 meter can be, smaller is OK, as long as you can put down the switch, if you consider expansion and heat dissipation, use a larger one), 130 crystal heads, clamping pliers, these two are used for network cables, and you don't need to consider adding someone to do the wire. Switches, the number of switches depends on the number of interfaces you choose, if it is 24 ports, you need 3, 48 ports plus a 12 ports or 24 ports, in short, you need to meet the needs of 50 machines, and you should also consider scalability, such as temporary access to the machine, switch connection, spare port, etc. >>>More

Pulling optical fiber can solve the problem, and it is necessary to use optical fiber transceivers, which is equivalent to replacing the network cable, after all, the effective transmission distance of the network cable is not as far as that of the optical fiber.
