What is mean by Network ID? And what is mean by Broadcast ID?

Question

In computer sciences what is mean by Network ID? And what is mean by Broadcast ID? Any relative site should be highly appreciated.

Answer 1

Network ID is considered the base or starting address for a particular network or network segment. For example if you are part of a network with IP address 192.168.1.5 . Typically your network ID would be 192.168.1.0. You can't really use the network ID address for sending messages, but the network routers are typically in close range to the ID for example if you would send a message to the Internet and you have a local network the router that forwards your message to the Internet would typically be located around 192.168.1.1 .

Now the broadcast address is the last address in your network or subnet work and is to send messages to all the computers in the local network when the intended host isn't known. This number depends on how your network is divided but typically for this network 192.168.1.X the broadcast address would be 192.168.1.255. For example if your computer with address 192.168.1.5 wanted to send a message to 192.168.1.27 and it didn't know where that was in you network, it would send a broadcast to every computer at 192.168.1.255. Then 192.168.1.27 would respond and say here I am and tell your computer 192.168.1.5 where to send the message to.

Answer 2

I'm not going to get too in depth here because you really should have these two concepts down for computer sciences, and the only way to do that is to work out the problems and figure them out yourself. Anyway, all networks have a network ID and broadcast ID; the network ID is the first IP in the network and the broadcast ID is the last IP in the network. The network ID along with the Subnet Mask will identify how many IPs are available on the network and the broadcast, along with the Subnet Mask, will allow a node to send a broadcast message/packet across its own network (this is used for finding DHCP servers, etc). This is all I have to say about this, I can spend a day on this topic alone.

ID is how the net knows who you are..
