Google Docs

Google Docs is Google’s online office suite application. It allows you to read and write documents, spreadsheets and presentations. In this review we will be concentrating on the word processing functions. Google’s aim is to use their online Docs applications to compete with computer based office suites. An online environment can offer certain advantages in this respect. When using an online application, your files are all automatically stored to Google’s web servers and automatically saved at regular intervals. This means that if your own computer’s hard drive crashes, you will still have your files available online.
