Who uses Twitter?
The Los Angeles Fire Department used Twitter during the California wildfires in October 2007. NASA have used it to update the public on its various space missions. Barack Obama used it extensively during his campaign and celebrities are now using it such as Stephen Fry.
As part of the upcoming Module 1 ECDL exam, you will need to know the different types of computer software and how an Operating System is different to other computer applications.
The following Youtube video explains Computer Software in Plain English.
If you see a black car with the Google logo in Ireland in the next few months, give a wave. This is the Google car used to capture images for Google Maps’ Street View.
Street View is Google’s online, interactive, panoramic street level photographic mapping system that is part of Google Maps.
The street car is now in Ireland taking images of Irish streets in five cities: Dublin, Cork, Limerick , Galway and Waterford. Google hope to have these cities on Street View within the next few months.
Street View has received a lot of media attention recently in the UK due to concerns over privacy. According to Google, their technology blurs out both faces and registration plates and people can also report details on Street View that are inappropriate.
So how useful is Google Maps’ Street View?
Tourists can use it to check a city they intend visiting, auctioneers could use it to sell houses and businesses are already using Google Maps on their websites to show their location. We use Google Maps on our school website.
The following Youtube video shows the European Commission President, José Manuel Barroso, receiving the 9 millionth ECDL Skills Card. Now all he has to do is pass all 7 exams to get his ECDL Certificate!
The next exam for Mr. Hannon’s ECDL class is scheduled for Thursday April 2nd in the Computer Room. This exam is on Module 5 – Database.
As discussed in class today, a database is simply a file that stores information or data. We actually use databases every day on the web e.g., searching for the book you want on Amazon, looking for a used car on Carzone. All businesses and organisations maintain a database of their employees and customers e.g., we have a database here in the school of all students.
You should divide Module 5 into four sections:
Tables
Forms
Queries
Reports
Use your CD and Syllabus as always to prepare for the exam and you should also look at the videos for Module 5 on Teach-ICT.com
