    The idea of cloud computing was introduced by the scientist John McCarthy. He introduced the term
                  timesharing which would enable the organizations to share a mainframe computer. But the term
                  “Cloud Computing” was coined by Prof. Ramnath Chellapa in the year 1997. In 1999, the first cloud
                  computing services websites launched were Salesforce.com and Google.
                  All  the  social  networking  sites such  as Facebook, LinkedIn,  Myspace,  Twitter, Netflix,  Skype,  and
                  WhatsApp use cloud computing. In fact, all your personal data, photographs, and other details that
                  you share on these websites are saved on the Cloud! OneDrive, Google Drive, Dropbox,  Amazon
                  Web Service, etc are some examples of cloud backup services, where you can save and keep your
                  data secure. Alexa and Google Assistant are natural language cloud-based bots. A bot is an automated
                  software program that can do repetitive tasks over the internet. Examples are chatbots, social bots,
                  Googlebot, etc.

                  Benefits of Using Cloud Computing

                  Some benefits of cloud computing are:
                       Cost Effective: It eliminates the capital cost of maintaining computing infrastructure.

                       Speed and Flexibility: It allows faster access of resources from anywhere across the globe.
                       Ease of Storage: It offers unlimited storage space relieving the user from the worries of running out
                     of data storage space. Users do not have to worry about backups. It allows co-workers to easily share
                     files and communicate with each other.
                       Data Security: It offers advanced security and reliability features to the user for their data. There
                     are many authentication, access control and encryption measures which do not allow unauthorised
                     access to sensitive data.

                       Green Computing:  By  maximizing  the  use  of  computer resources, lowering  energy  use,  and
                     minimizing e-waste, cloud computing supports environmental sustainability.

                  Risks of Using Cloud Computing

                  Some risks of using cloud computing are:
                      Your sensitive data might be at risk from hackers.
                      Some people might face issues like data loss.
                       The user is always dependent on the Internet. So, if the user is unable to connect to the Internet, he/
                     she cannot access the files and data.
                  Because of maintenance needs, or even cyber attacks, cloud service providers can face downtime.
                  Users may not be able to access their data during these times.

                  OneDrive

                  OneDrive was launched by Microsoft in 2007. It was also known as SkyDrive. OneDrive is a cloud file
                  storage service. This cloud-based service gives the users a space to store and share documents. When a
                  person is working on multiple projects, he /she has to deal with loads of files. These files occupy a lot of
                  disk space on the laptop or desktop. The person might even want to access the images and documents
                  from his / her mobile, iPad or laptop.
