If they are both Windows computers, and they are connected to the internet, then they may not see each other unless they are part of the same Workgroup or Domain. Your computer is assigned an IP address by your router when it starts up. Domains are only used at businesses and other organizations with many computers, Workgroups are used on small LANs without a domain controller. In either case, you only need the Names of the computers for them to connect to each other, and you can browse for other devices in the same Workgroup or Domain. They both run the TCP-IP networking protocol, and they both use DNS to find other computers on the internet. The MAC address is a unique number of every network device and is the fundamental way they all communicate with each other. It is like your MAC (physical) address compares to your IP Address (e.g. a phone number), but you don't need to worry about it as it is automatically configured for you.

Why do computers need a name IP address and a MAC address?
That is actually the way the computers connect. Parts of the IP address are used to route the data to the correct ISP, and the rest are used for the network can find the other machine. If you use any site, they already know your IP address, since that is necessary so the servers will know where to send the data.
Example of a TCP IP address and netmask?
It is called "IP address". A typical example, using private addresses, is:IP address: 10.0.0.5Subnet mask: 255.255.255.0Default gateway: 10.0.0.1IP address will be different for different computers, but typically all will start with the same 3 bytes, in the example, "10.0.0". Subnet mask and default gateway will be the same for several computers in the same network.It is called "IP address".

Why can all computers communicate via email?
they are all connected through the same internet or an line web
Can two computers use the same ip address to send emails?
We can have same ip address on two or more computers in the SAME network; both working simultaneously. They should be in same collission domain. Let their MAC address be same first & then assign them same ip address. You can do so by using a network hub. Watch my associated video on www.metacafe.com/channels/austinium2002/
If you have 2 computers in the same house can it interfer with trying to play Age of Empires II over the internet if both computers show the same IP address?

If 2 computers have the same ip address will it slow down the internet connection?
yes
What happen if i assign a single IP address to two computers which are on network.now if third computer wants to access on computer with that IP address what happens?
No two computers may have the same IP address. This will cause both systems to crash.
Does every computer have a different ip address?
No, an IP address is given to each internet provider, not each computer. For example, there could be five computers hooked up to the same network in which case they'd all have the same IP address.
What happen if two computers have same ip address?
windows will flash up and tell you there is a conflict
