The school classroom computer LAN is formed, and the 50 computers in the school computer room need w

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.

The above is from the hardware facilities method to say the basic equipment of a computer room, the specific things depend on your specific requirements, I hope it will help you.

Layer 2 switches are internal, and Layer 3 switches (which can replace routing) are external. Probably the second layer is not standardized, and the third layer uses a Cisco 3560 on the line.

1。Buy a few more machines.

2。Buy a multi-port router.

3。Buy n network cables.

It's not easy to set up a local area network? Geographical space constraints, expensive hardware equipment, professional and technical personnel? No, no, no, the cloud area network says:

It's so simple! As long as you have an internet connection, I can help you easily connect devices from all over the world into one or more LANs!

Adopt me, leave your mailbox, and I'll give you the topology map.

Networks such as schools generally have virtual speeds.

Of course, I don't know about the university.

In general, schools are connected to the local education metropolitan area network, connected to the Education Bureau through the optical fiber or ADSL of Netcom or Telecom, and then released information through the external network port of the Education Bureau.

If the network speed is too slow, one, you can test it on a single machine, maybe other machines have ARP. If there is no problem on the stand-alone machine, it means that your intranet is toxic. Checking for drugs is fine.

Second, call the education information network manager of the local education bureau**. Sometimes it is.

The metro network is adjusting.

Your question has nothing to do with whether you are connected to telecom or Netcom. Even your DNS has nothing to do with telecom and Netcom. It is the value that the network center of your metropolitan area network education bureau gives you.

If you have any questions, you should contact your local school bureau network center.

Your school should have them**.
