   • Advantages
     • 1.Cost – Backing up your data isn’t always cheap, especially when you factor in the cost of any equipment needed to do so – think external hard drives or backup tapes. Additionally, there is the cost of the time it takes to manually complete routine backups. Online storage services reduce much of the cost associated with traditional backup methods, providing ample storage space in the cloud for a low monthly fee. 2.Invisibility – For all intents and purposes, cloud storage is invisible; with no physical presence, it doesn’t take up valuable space at home or in the office. 3.Security – Storing confidential or sensitive information in the cloud is often more secure than storing it locally, especially for businesses. With online storage services, data is encrypted both during transmission and while at rest, ensuring no unauthorized users can access the files.

4. Cloud Computing

   • Online storage
     • Cloud storage is a model of networked enterprise storage where data is stored in virtualized pools of storage which are generally hosted by third parties. Hosting companies operate large data centers, and people who require their data to be hosted buy or lease storage capacity from them.

5. Online Communication

   • Micro blogging
     • the posting of very short entries or updates on a blog or social networking site, typically via a mobile phone.
   • Chatrooms
     • an area on the Internet or other computer network where users can communicate, typically one dedicated to a particular topic.

6. Ubiquitous Computing

   • RFID
     • The acronym refers to small electronic devices that consist of a small chip and an antenna. The chip typically is capable of carrying 2,000 bytes of data or less. The RFID device serves the same purpose as a bar code or a magnetic strip on the back of a credit card or ATM card; it provides a unique identifier for that object. And, just as a bar code or magnetic strip must be scanned to get the information, the RFID device must be scanned to retrieve the identifying information.
