Here are some 10 useful tools;

Google E-mail:
         Gmail started out as Google's internal e-mail service. When Google decided to make Gmail available to people outside of the company, it chose to take a gradual approach.At first, the only way to get a Gmail account was to receive an invitation from someone else.Google purchased the online messaging service Jaiku in 2007. Jaiku is similar to Twitter -- it's a microblog application. Jaiku users build up networks of contacts. Then they can send and receive short messages using a cell phone, computer or other device connected to the Internet.

GTalk:

That means you can make PC-to-PC calls to other Google Talk users.

Google Checkout:
         Many people use the Internet to shop.Some may feel nervous about giving Google their credit card information. Google stresses that it takes security and privacy very seriously. Since the merchant never sees the credit card number, there's less of a chance for someone to abuse the user's information. But it also means that Google's databases become an attractive target for hackers who want access to lots of credit card numbers.First you create a Google account, then you'll need to enhance it by providing a credit card number, billing address, shipping address and a phone number. Once you complete this step, you can go shopping.

Google Calendar:
         If you don't have one, you can register for a free account.You can use Google Calendar to schedule events and invite people to participate. By sharing folders, you can compare your schedule with other users. If everyone keeps his or her calendar up to date, it's easy to avoid conflicts. A single user can open multiple calendars and view all the scheduled events in a single window. Google displays each calendar's events in a different color.

Google Docs:
        The Google Docs suite marks Google's attempt at getting into the online productivity software game. Instead of saving all your data to your computer's hard drive, you save your Google Docs files to a remote Google file system. Google Docs is a good example -- to build out the suite, Google bought the following companies:

• Upstartle, which designed the word processor Writely
• XL2Web, creator of an online spreadsheet application called 2Web Technologies
• Tonic Systems, the company responsible for the presentation application

Google Maps:
        Google Maps lets users view maps of specific regions and get directions from one location to another. Google Maps allows users to view street maps, topographical terrain maps or even satellite views. The Google Maps feature relies on digital map images from NAVTEQ. NAVTEQ provides map data to many different clients, including in-vehicle navigation systems.A company called deCarta -- formerly Telcontar -- provides the applications that power the mapping features.

Google Earth Maps:
        Google is always looking at new ways to organize and present information. One of those ways is to geotag data. Geotagging is a way of linking information to a real-world location. You view geotagged information on a map. While Google Maps could serve as a way to provide geotagged information to users, Google decided to go with an alternative.Google chose a digital globe and called it Google Earth.

Google Desktop:
         Google Desktop can come in handy.It's a downloadable application Google offers free of charge. Once a user downloads and installs the application on a computer, Google Desktop goes to work. It searches and indexes the files on the user's computer.

iGoogle:
        iGoogle, a freeaggregator or portal Web service. The iGoogle service allows users to select multiple applications and news feeds from across the Internet. Each user can customize his or her own iGoogle page.

Google Health:
        Google's solution to this issue is to create an electronic, centralized location for your medical files called Google Health. Your doctors would transfer your files to Google's databases. Instead of having to track down the physical location of a paper file, your doctor would be able to log in to a computer and pull up your entire medical history. You don't have to worry about remembering which doctor has your file.
