Do you know?

                     The databases of individuals are stored by the search engines when someone subscribes or uses some
                     service in the Internet. Most of the free e-mail providers optionally ask the users to fill in various details
                     which are categorized and saved for future use or reference. We can’t find any person who has not
                     subscribed to a service on internet or who has not uploaded any kind of personal information on Internet.



                   WEB SERVICES

                 A web service can be defined as a piece of software or application or cloud technology that is available
                 online and  provides standardized web  protocols (HTTP or  HTTPS) to communicate  and  exchange
                 messages. There are various types of web services available on the Internet. Let us learn about some of
                 them in detail.

                 Web Chatting

                 Talking in real-time (at the same point of time) with other person is said to be chatting. Internet provides
                 facility to communicate in real-time among users. Real-time communication means communicating with
                 other users instantly. Unlike e-mail, in web chatting there is practically no waiting period between the time
                 when a message is sent and the time the recipient reads the message.



























                 During web chatting,  more and  more people can join the chatting  group to exchange  the real-time
                 messages amongst one another. Chat messages are typed on a user’s computer and sent to the channel
                 where all the users who have joined that group can read the message. The recipient can then read, reply
                 or ignore that message or can create his message and resend it for synchronous conferencing.
                 Web chatting refers to online communication among different users on Internet who instantly share text,
                 images and sound files with each other in real-time. A user must have an ‘ID’ as his identification for
                 chatting. If the user is new, he needs to create ‘ID’ for himself before chatting.

                 Apart from computer and connection to Internet, the accessories like web camera, microphone/headphone
                 are required for web chatting. There are many sites which facilitate web chatting, like Google Chat, Skype,
                 Facebook, WhatsApp, etc.
