1 Make an Ethernet cable and connect a computer to the LAN.

1 Make a network cable, one end is connected to the router or switch of the local area network, and the other end is connected to the computer. (Network cable method: 8 wires orange and white - orange - green and white - blue - blue and white - green - brown and white - brown, the same at both ends).

2 Set the same gateway as other computers in the local connection, subnet mask, and the network segment of the IP address is guaranteed to be the same as the network segment of the other computer (if other computers are, your IP address will be set.)

3. The working group guarantees that it is the same as the other computers and that it can ping the IP addresses of other computers.

4 On the folder you want to share, right-click Properties, select Share, select Share this folder, and select OK.

5 Right-click "My Computer", select "Manage", open Local Users and Groups, find the user, double-click Guest, remove the check mark in front of "Account Deactivated", and set the password to empty.

6 Click Start, Run, Enter, enter in the lower left corner, enter the local policy, find the user rights assignment, and on the right side put "Deny access to this computer from the network.""All users in are deleted.

6 Still a local policy, find the security option, and on the right side, change "Sharing and security module for local accounts to "Guest Only", and change "Account: Local accounts with blank passwords are only allowed to log in to the console" to "Disabled".

7 Find the name of the computer in the online neighbor on another computer and double-click it to access the file.

Didn't you say it very clearly, just make a network cable?

Summary. According to the networking rules, the planned network should be planned to the next three to five years, and according to the required needs, in the next three to five years, the number of desktop computers will be roughly maintained at 200, mainly to increase the performance of the wireless network. Since this is a small local area network, computers are scattered in dense distribution, so it is best to choose a wide network.

It is possible to connect all desktop computers to one interchangeable machine, and all desktop radio stations can be connected to each other's wireless network builders enough to install two wireless access devices. It is more suitable to put the computer room in place. The convergence and exchange machine of the exchange room is connected to the external network through the router and firewall to realize the interconnection network.

In addition, two servers need to be configured in the computer room, which can provide fast resource sharing and external network access for the local area network. It is also necessary to configure a desktop computer in the computer room to facilitate the management of the network.

Design a small local area network, using optical fiber, network cables, switches, routers, firewalls, wireless networks, to meet the needs of 200 computers to access the Internet. 1. List the selected equipment, the number of cable models 2, draw the network topology diagram 3, and explain in detail the ideas of designing the network, the characteristics and advantages of the network design, such as in terms of network performance and network security.

Hello dear. We'll be happy to answer for you.

It is also necessary to configure a desktop computer in the computer room to facilitate the management of the network.

The bus topology is to connect all the devices in the network directly to the common bus through the corresponding hardware interface, and the nodes communicate with each other in broadcast mode, and the information sent by one node can be "listened" by other nodes on the bus. Advantages: simple structure, easy wiring, high reliability, easy expansion, node failure will not affect the system, is the topology often used in local area networks.

Intranets use private Class C addresses to divide subnets and dispatch addresses, because some subnets require different addresses, and CIDR (Classless Inter-Domain Routing) technology and equipment that can support this technology.

Straight line: The line sequence at both ends is the same, from left to right: white orange, orange, white green, blue, white blue, green, white brown, brown.

Crossing lines: one end is the line sequence of the positive line, and the other end is from left to right: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown.

568a White-Green, Green, White-Orange, Blue, White-Blue, Orange, White-Brown, Brown.

568b White-Orange Orange White-Green Blue-White-Blue Green-White-Brown Brown.

1. Parallel line production.

Use 568a or 568b at both ends

Second, the production of cross-network cables.

One end is made with 568b, and the other end is made with 568a.

3. Reverse cable production.

The line order of one end is opposite to the other end, and the color is not required.

1. The 7 and 8 of the RJ45 interface corresponding to R are DC power inputs, and must not be mixed with the signal lines (1, 2 and 3, 6).

2. 1,2 must be a pair of twisted pairs;

3,6 must be a pair of twisted pairs.
