Dns Servers How do they work?
Casanova1405241497 replied to nightfox1405241487's topic in Websites and Web Designing
While most of this topic doesn't require much technical knowledge, there is one technical part of DNS you should understand in order to grasp the political issues.When you type a name, like "eff.org" into an internet program, it needs to find a way to map that to the internal routing number the internet really uses to reach the EFF computers. We at the EFF want you to be able to reach us using that name, too.To do that, your computer uses DNS like a database. DNS translates from a name like "eff.org" into a raw number called an IP address. All internet traffic requires these numbers to work. Some computers do your DNS directly, but with most personal computers, your PC asks another computer at your ISP or corporation to do the work. The important point is that the looking up of the name is normally done by a computer you or your site controls, or one you pay to do such work for you. That computer has a list that was installed in it by the people who run it. In almost all cases, that list just came with the DNS software, because everybody in the world uses a similar list. It's a list of what are known as the "root" servers of DNS. These are the master servers that can help you look up (resolve) any name you want to ask about.There are about a score of these root servers around the world, and they all copy their own data from one master server, which is under the control of ICANN. Each one has the same data inside. The root servers don't actually contain much. They mostly list where you will find the servers that can look up names in the "top level domains" like .com, .org, .us, .uk etc.Once the root server tells your system where the master ".org" server is, your system asks it where "eff.org" is. In particular, it gets back the raw internet IP address, the low level "phone number" of the internet. With that answer, your computer can talk directly to the computers at eff.org(Quite often this is more efficient than it sounds because all the computers along the path remember the answers to questions they have asked recently, and don't need to ask them again.)The important thing to know from all this is that while ICANN controls the master root server, and the other root servers are copies (mirrors) of it, and almost everybody uses the same list of root servers, there is no law that makes this so. A few people can, and do, use other lists of root servers. In theory, if enough people got upset at ICANN and the root servers, they could switch to another set, and that other set could look up names for you any other way you might choose.In practice, such a switch would be very hard to do, especially a switch that changed who the master for ".com" was from Network Solutions to come other company. If people switched, some people might get a different answer for whoever.com than others do. You couldn't hand out a domain name on your business card and expect it to work reliably for all the people you give it to.So while there is no actual legal power in ICANN, there is a natural monopoly for the "root" (master) of the domain system, because if everybody doesn't use the same list, we lose some valuable features -
What Is Dns And How Does Dns Work?
Casanova1405241497 replied to nightfox1405241487's topic in Computer Networks
DNS, stands for " Domain Name System" and helps resolving names to IP numbers as it is much easier for people to remember logical names rather then a 12 digit number.DNS uses 3 major components ”Resolvers (client)”, Name Servers” and ”Domain Name Space”. In basic DNS communication a client (Resolver) sends a query to a Name Server, which returns with the requested information, or an address for another Name Server, an error message is received if the query gives no results -
i think , Short for Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium. Consequently, each different type of network medium requires a different MAC layer.On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address. i think it might be get u some information by this

Msn Messenger 7.0 Or 6.2? which one is better
Casanova1405241497 replied to harriko's topic in Computer Networks
i suggest to go for 7.0 as its a new one and has many features than comparision to 6 , many times the when i buzz any of my friends they seem to online but when i enquire them later , they say they were not online on that certain point of time , the smileys are also great than the previous one . but i am not aware of the problem or the trojans which can access the system without our imformation as rudy was saying , but i am quite sure that msn messg 7.0 will try to get rid of the minor problems which were in 6.2 -

The browser must stop the pop ups which really sucks , thats tyhe major problem with internet and another browser but mozilla is rather good from these which does not allow the pop ups but its not that speed as opera but u must be happy with some thing or other wat say ? NYway i use mozilla right now .An i agree with sPyfReEsTyLe
