NetBEUI - TCP/IP

Hi,
Netbeui works on computer name and does not requires any configuration.It uses computer name for communication with other computer.Due to this it is fast protocol as compared to tcp/ip.
Tcp/ip requires some configuration such as ip address, subnet mask.In this protocol computers communicates with each other with this ip address and subnet mask.Ip address is given in numaric format like this 10.31.2.9.Due to configuration this protocol works slow as comapared to netbeui.
U can use both in ur network it makes no problem for network.But if ur network is very small like of 5-10 computers then best use netbeui.But if ur network is large or have computers more than 10 then use tcp/ip and can also use netbeui.But if have very large network of 100 or more best to use only tc/ip as netbeui can create rpoblem of broadcast stom.

The above answer is correct. But we need to add one more thing.

If you will be getting on to the internet, you MUST have tcp/ip. That is the protocol which us used for browsing the web. You can use both protocols on a local network, but for the internet, you must have tcp/ip

To add to the others the difference is that NETBUEI is a none routable protocol and PCP/IP is routable and is the main protocol used over the internet

If you need added security on workstations unless they need to go onto the internet dont give them TCP/IP that way if anyone hacks into the system they wont see the NETBUEI stuff
