INTRODUCTION
     With traditional desktop computing, we run copies of software programs on our own computer. The documents we create are stored on our own PC. Although documents can be accessed from other computers on the network, they cannot be accessed by computers outside the network. This is PC centric.
      With cloud computing, the software programmes one use aren’t run from one’s PC, but are rather stored on servers accessed via the internet. If a computer crashes, the software is still available for others to use. Same goes for the document one creates; they’re stored on a collection of servers accessed via the internet. Anyone with permission can not only access the document, but can also edit and collaborate on those documents in real time. Unlike traditional computing, this cloud computing model isn’t PC centric, its document centric.
DEFINITION
Ø Cloud computing is a type of computing that relies on sharing computer resources rather than having local servers or personal devices to handle applications.
Ø A type of internet based computing where different services such as servers, storage, applications are delivered to an organization’s computers and devices through the internet.
Ø A model for enabling ubiquitous, convenient, on demand network access to a shared pool of configurable computing resources(e.g.; networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction” NIST (US National Institute of Standards and Technology)
Ø Cloud computing is an extension of the concept of distributing computing- which is the process of running a program or application over many computers connected by a network. The internet makes this process easily achievable even for the general use.
Ø Cloud computing is an internet based computing in which shared resources, software and information are delivered as a service that computers or mobile devices can access on demand.
EXAMPLES
Google App, e mail, you tube, twitter and drop box
CHARECTERISTICS
Ø Virtually assemble
Ø Pay per use
Ø Shared workloads
Ø Massive scale
Ø On demand self service
Ø Off site technology
PRESENT EDUCATIONAL SYSTEM
v It based
v Facing a future where majority of educational services  will be hosted in a cloud
CLOUD COMPUTING IN EDUCATION
Enables users to access data via the internet. Main users of institution are connected to the cloud. Separate login for all the users for their respective work.
Main users includes students, faculty, classes at college, administrative department, examination branch, class preparation and review at home by faculty, migration to other colleges etc.
A.                       Advantages for the teachers
Ø Upload their class tutorials, assignments and tests on cloud.

Ø Personal attention can be given to students.
Ø could cover more portions
Ø Transform passive to an active classroom
Ø Teacher can collaborate to share their ideas online

Ø Can clarify their doubts personally
Ø 24 x 7 teacher
Ø Gets training for self instruction
Ø Motivated and increase the attention level
Ø Develop research skills at younger ages
Ø enhance interaction with teachers and friends
Ø Update with happenings in the world
C.   Advantages for educational institution
Ø Institutions no longer have to host their own data centers.
Ø No expensive hardware needed
Ø No power bills
Ø No staff salaries
GENERAL BENEFITS OF CLOUD COMPUTING
·      Personalized learning :
v great student choice
v can access wide array of resources
v select software that suit their learning styles and interest
·      reduced cost
v can use applications for free without having to purchase, install
v can keep applications up-to-date for free
v for some application facility of pay per use
·      accessibility
v 24 x 7 accessibility
v Can login and access information from anywhere


·      No extra infrastructure
v Present goal of institutions is to make more research facilities available
v Make environment global
v Need not worry about building, labs, teachers as everything available virtually in cloud
·      Go green
v Reduce the carbon foot print
·      User friendly
v Easy to understand and easy to operate
·      Instant software update
·      Unlimited storage capacity
·      Universal document access



DISADVANTAGES
  Easy to hack: protection of data is a major issue
  Unsolicited advertising: provide with target users with unsolicited email or advertising
  Requires constant internet connection
  Does not work well with low speed computers
  Individuals may at time feel lonely and impersonal.
CONCLUSION
     The cloud will be the next evolution in the history of computing. It has caught the imagination of consumers, businesses, financial analyst and educational departments.
