Working in the cloud.

Some internet services let us create, save and modify documents online. This is called 'cloud computing'.

The two main advantes of these services are:

• Access to our files easily with other people.
• The ability to share our files easily with other people.

In addition to storing and sharing information  in the cloud, we can also use programs for word-processing, spreadsheets and presentations.
Examples: Picassa, flickr, gloogle drive, dropbox...

Social bookmarking is an internet tool that lets us organise, use and share information more efficiently. The most popular social bookmarking applications are:

• Delicious is a service taht lets us save our favourite web pages along with a description and a list of key words for easier classification
• Diigo defines itself as a multi-tool for knowledge management. It lets us bookmark the pages that we visit and create a digital library in the cloud, with links, notes and images.

Web pages and RSS

Web pages and Rich Site Summary (RSS) are the most common sources of online information.

• A web page is a collection of documents that can include text, audio, video, images and hypertext links to other web pages. A browser is a program that locates a web page by its address and lets users access the content. A search engine is a web page with a database of information about other web pages and their content.

• Rich Site Summary (RSS) is a subscription service that provides users with frequent updates from media websites, blogs and other sources of information. In this way, people can keep up with current issues that interest them.
