What happens when enter text into address field?

Posted in Uncategorized on January 13, 2009 by kylegraeme

What happens when you enter http://www.holycross.bc.ca into the web address field is a long list of requests and travel which happens in about 1 second. As soon as you enter the address into the address bar, it sends a request out to the DNS server for the information of the website your requesting. Somewhere along the line, you also go through your ISP’s server, and eventually you get to the IP address of the website you are requesting. Your request leaves your computer goes through your isp’s DNS, bounces through a bunch of other computers along the way, gets though the requested institutions DNS then goes through a bunch of nodes and in about 1 second you see the information your request.

Definitions

HTTP stands for HyperText Transfer Protocol. The reason it is used with web addresses is becuase every different kind of communication on the Internet requires a different protocol.

Browsers access information from remote servers much differently than say, a File Transfer client does. For this reason, protocols were established so that servers could understand exactly what it is the client wants.

HyperText Transfer Protocol is a defined set of steps that a client must follow in order to obtain data from a web server. This process, or protocol, is followed for each and every single piece of data downloaded from a web server, and this is why the prefix “http://” is included in every URL on web pages, even including the links.

DNS – The Domain Name System associates various sorts of information with so-called domain names; most importantly, it serves as the “phone book” for the Internet by translating human-readable computer hostnames, e.g. http://www.example.com, into the IP addresses, e.g. 208.77.188.166, that networking equipment needs to deliver information. It also stores other information such as the list of mail exchange servers that accept email for a given domain. In providing a worldwide keyword-based redirection service, the Domain Name System is an essential component of contemporary Internet use.

IP Address – Any computer or other technological device that is publicly connected to the Internet is given a unique number called an IP (Internet Protocol) address. IP addresses contain four groups of numbers that are separated with periods, and each number group can feature number(s) that range anywhere from 0 – 255. An example of an IP address is 1.123.13.231.

Traceroute or Tracert – When computers communicate over the Internet, there are often many connections made along the way. This is because the Internet is made up of a network of networks, and two different computers may be on two separate networks in different parts of the world. Therefore, if a computer is to communicate with another system on the Internet, it must send data through a series of small networks, eventually getting to the Internet backbone, and then again traveling to a smaller network where the destination computer resides.

Product number one on the pedestal is the renowned Apple I-Phone. This new mobile device won many awards including the best mobile technology award of 2008 in the British Technology Awards. The I-Phone was  a revolutionary piece of technology, having capabilities that no other cellphone had to date.

Its seamless browsing and downloading skills made application downloading and phone functionality better and more personal than ever before. The ground breaking dual input touchscreen was revolutionary and inspiring for many Iphone clones and copies. Although call quality isn’t stellar the sheer vibrant display as well as sleek design, and an innovative multitouch user interface. Its Safari browser makes for a superb Web surfing experience, and it offers easy-to-use apps. As an iPod, it shines. The Iphone is an inspirational piece of tech for all.

Second piece of technology is a very different sort of technology but it also won a presitigious award at the BTA’s, Google Maps won the “Most Indispensable Technology” award. If you don’t already understand what indispensable means it can also be worded as “necessary, needful, required, requisite.”

Google maps is a free online software program that has helped many people find their way. Not only is it much more efficient and more accurate than map quest or any other online competitor, it can be downloaded onto the I phone and some other mobile devices. Even though it is not as functional as a gps, it does the best job in the market for online map making software.

The only criticisms made about Google Maps is that it only works on java enabled phones which leaves people on Verizon out in the cold, and that people will have to shell out about $80 a month for a data plan. But the good far outweighs the bad being able to conduct searches reveal relevant information such as phone numbers and addresses; easy pan and zoom features; lets you find types of businesses in a particular area; step-by-step driving directions; click-to-dial feature in Google Local for Mobile. Which makes Google Maps a great revolutionary technology for 2008 and best of all its free!
