2. 2 After listening to my lecture, you will be able to know the following:- PDAs and Cloud Computing PDAs and Cloud Computing Pedagogical applications of PDAs Pedagogical applications of PDAs

3. 3 About PDA Personal digital assistant or personal data assistant It functions as a personal information manager A typical PDA has a touch screen for entering data, a memory card slot for data storage, and IrDA, Bluetooth, 3G and/or Wi-Fi.

4. 4 Cloud Computing Cloud computing is a marketing term for technologies that provide computation, software, data access, and storage services. It does not require end-user knowledge of the physical location and configuration of the system that delivers the services.

5. 5 Cloud Computing Cloud computing providers deliver applications via the internet, which are accessed from web browsers, desktop and mobile apps. The software and data are stored on servers at a remote location.

6. 6 Cloud Computing What is ? With cloud computing, the software you use are not run from your personal computer, but rather stored on servers accessed via the internet. If your computer crashes, the software still available for others to use.

7. 7 Cloud Computing What is not ? First, cloud computing is not network computing. First, cloud computing is not network computing. With network computing, applications./documents are hosted on a single company’s server and accessed over the company’s network. With network computing, applications./documents are hosted on a single company’s server and accessed over the company’s network.

8. 8 Cloud Computing Cloud computing is a lot bigger than that. It encompasses multiple companies, multiple servers and multiple networks, plus unlike network computing, cloud services and storage are accessible from anywhere in the world over an internet connection. With network computing access is over the company’s network only.

9. 9 Cloud Computing Cloud computing also is not traditional outsourcing, where a company forms out (subcontracts) its computing services to an outside firm. While an outsourcing firm might host a company’s data or applications, those documents and programs are only accessible to the company’s employees via the company’s network, not to the entire world via the internet.

10. 10 Cloud Computing So despite superficial similarities, network computing and outsourcing are not cloud computing.
