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.
