a real MUST READ!!)), but it is also a little faster, hence programs such as Real Player (see http://www.real.com) use it for streaming video and more, where losing a single packet(32) or two is not such a big deal.8. ICMP - stands for Internet Control Message Protocol. A protocol used for transferring errors over a network (the Internet, local networks etc').9. IP address - every computer connected to the Internet has an IP address. If another computer wants to interact with your computer it will need your IP, just like you need another person's phone number to call him.IP addresses should look like that: x.x.x.x, where x can be a number between 0 to 255.Note: there are "special" IP addresses which aren't use to connect to other computers. For example: 127.0.0.1 means localhost, which means you (your computer). Connecting to a certain port(2) on the IP 127.0.0.1 will connect to that port on your computer.Oh, by the way, IP stands for Internet Protocol(18).10. Hostname - hey, guess what! I just found out this really cool site! But I can't remember it's IP address, and when I do, I hate typing in these long IP addresses(9). Sure, I can bookmark it, but what if I'll want to tell my friends about it? Or what if I'll be surfing from my friend's house or from a public place and I won't have my bookmarks?The answer to all of these questions is hostnames.Hostnames are aliases to IP addresses. A list of hostnames and their IP addresses is located at InterNIC, which is a database of all hostnames and their IP addresses.When you type in a hostname, your computer will look up that hostname and find the appropriate IP address and then connect to it.But instead of having to overload InterNIC (imagine that the entire world will connect to them. This would surely overload their servers and they will have to spend money on constant upgrades and backups. And think what will happen if something bad will happen to their databases...). The solution for thi...
