For example, Windows NetBIOS and client/server technologies like SQL would use the "Session" layer (Layer 5) above the Transport layer. It is merely presented for those who wish more in-depth information. You should use IP's that have been reserved for private networks.

Note: Using different numbers in the "computer" portion of address as in the previous example is not the same as the "subnetting" we referred to when discussing the 10.x.x.x network address Note in the above diagram that if you use a commercial cable/DSL router you may need one of two things (it depends on the switch you have).

The private IP addresses assigned to the systems on your internal nework are chosen by you from one of the three private address ranges listed below. Firefox and Thunderbird print to the virtual printer just fine. The concept of sharing an Internet connection is the same no matter what type of Internet connection you have. If you enter the command: shutdown -r now the system will immediately begin to shut down.

Since there aren't enough addresses for this, companies instead assign all of the hundreds of computers in their organization private addresses and they all share a single "public" address to access Related: PCs Utility Software OS X Storage Network Storage You Might Like Shop Tech Products at Amazon PCWorld PCWorld helps you navigate the PC ecosystem to find the products you want So even if you don't need to share your broadband Internet connection with other PCs (i.e. It could be that the pages aren't displaying properly or they could be trying to access the Web server by name and they're having DNS issues on their workstation.

They listen for network connections from clients, which request them to perform an action or provide information. At layer 3, can you ping the Web server?

This is done under Network Properties in the control panel. (See Windows help for details, but I found it self explanatory.) Each machine must have an IP address assigned. A socket is simply referencing the IP address and port number together. Note that it's the server applications that open ports.
