This is how you wow your friends at dinner parties….
As you surf the web- (Reposted from OlderCitizens.com) you will reach a place where no pages exist. This is called an 404 Error . While out surfing somewhere can’t remember where, I reached this splendid 404 Error
….can I get a hug? So sad……Next time you get a 404 Error maybe, just maybe, think of the server!
Now you know what a web server does, it serves web pages, you need also to know about Domain Name Servers or DNS.
Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses.
This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.
Information from all the domain name servers across the Internet are gathered together and housed at the Central Registry. Host companies and Internet Service Providers interact with the Central Registry on a regular schedule to get updated DNS information.
When you type in a web address, e.g., OlderCitizens.com , your Internet Service Provider views the DNS associated with the domain name, translates it into a machine friendly IP address (for example 22.214.171.124 is the IP for OlderCitizens.com) and directs your Internet connection to the correct website.
After you register a new domain name or when you update the DNS servers on your domain name, it usually takes about 12-36 hours for the domain name servers world-wide to be updated and able to access the information. This 36-hour period is referred to as propagation.
Well yes mine are done immediately even if I have to tell a tech to kick start it which i frequently have to. I do it via chat. I run my own web server through HostGator an excellent company been with them for oooo ages years. I also have my own DNS Domain Name Servers. I have two, ones for back up.
It literally takes minutes to set up a new domain.
Phew it made me sweat: Watch Full Screen.
As you may have guessed I like the blues. I blog about them in snippets and I usually make videos to blues music. However its not all video I take the odd still shot.If you want access to stunning art work join DeviantArt.com Here’s a picture I created its on my deviantart site: Flikr.com is very good too
If you want to create graphics yourself a very good program that I use as my main image editor is Microsoft Expression Design and its available as a free download link ed from my Useful Program page here its so much better than paint. There is also a video to get you started. There are tutorials but just simple stuff like putting text on a picture its very cool. Worth learning though it takes some effort. But be brave you wouldn’t have got here now if you weren’t secretly as tough as old boots.
So : A web server serves web pages; name servers (dns) are a phone book that translates names into numbers; http:// is hyper text transfer protocol that precedes every web page.
If you want to see an example of a blog post here is probably the best blog post I ever created IMHO its called:
