Wikis

Wikis are a collection of web pages making information on a variety of different subjects. Anyone can edit a wiki so more and more information can be added all of the time. A very famous wiki, wkipedia, is looking to collect all of the world's information on one web page.WikiWikiWeb was the first site to be called a wiki. It started to be developed in 1994 by a man called Ward Cunningham. he was inspired by Apple's hyper-card. This was a group of virtual cards all with different information on. Common uses of wikis are project communication, intranets, and documentation.Since anyone can edit a wiki the information you use from a wiki could be complete rubbish. Therefore wikipedia employ a lot of people working on making sure the information on wikipedia is true. This is obviously very hard to police so ultimately a wiki will only work if people editing the pages are being helpful.This sums up wikis really well. The more synical you are thus the more untrustworthy you are, wikis will not be good for you. But if you use them cleverly they are often a lifesaver

Google Earth

Google Earth is a satellite image of the Earth. It allows you to see pictures of the whole world via a click on your computer moniter. The more densely populated areas or areas of greater interest to the general public have a greater quality picture. It is good that google earth is freeand can be downloaded by anyone who has connection to the Internet. Google Earth Plus, which includes added features, and Google Earth Pro, costing $4oo per year, which is used more for commercial use.On the newer versions of google earth, a flight simulator has been introduced. You can fly a plane through famous cities and landmarks. Other features added to the original google earth include google sky and street view.I first used Google Earth around 4 years ago. I love using it because it is fun to see your house and other peoples houses by just writing the name of it. It also gives me the chance to look at places I will probably never visit which is exciting because i can see all the famous places all over the world for free.It could be very useful for all sorts of people. It may also be used by police to track criminals down. People wandering what the neighbourhood looks like of their friend's or families' new house looks like can easily search it on google earth. In short, Google Earth is revolutionalizing the way we can look at the world and should be enjoyed by all!
