Internet has given people a much wider choice and has opened up new avenues for them to communicate with others as well as to collect and share information.
Services that the Internet provides to the people have greatly affected our society in almost all areas of human endeavor, be it in business, learning, banking, shopping, making reservations for restaurants, booking movie tickets etc.
Let us learn about the various services provided by the Internet.
(A) E-mail :~
(B) Chatting :~
Chat is a text-based communication that is live or in real-time.
Online chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver.
Chat messages are generally short in order to enable other participants to respond quickly. Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Internet forums and email.
Online chat may address point-to-point communications as well as multicast communications from one sender to many receivers and voice and video chat, or may be a feature of a web conferencing service.
Chat may be delivered through text, verbal, audio, visual or audio-visual (A/V) communication via the Internet.
If conducted through a desktop, chat requires software that supports Internet Relay Chat (IRC) or an instant messenger application, where a central server manages chat communication between different end user clients.
On the Internet, chatting is talking to other people who are using the Internet at the same time you are. Usually, this "talking" is the exchange of typed-in messages requiring one site as the repository for the messages (or "chat site") and a group of users who take part from anywhere on the Internet.
In some cases, a private chat can be arranged between two parties who meet initially in a group chat. Chats can be ongoing or scheduled for a particular time and duration.
Most chats are focused on a particular topic of interest and some involve guest experts or famous people who "talk" to anyone joining the chat.
There are also online chat services that require users to sign up with a valid email address. After signing up, a user may join a group chat room or send a private message to another individual.
Online chat services have purpose-built chat interfaces that manage the entire communication processes.
The first online chat system was called Talkomatic, created by Doug Brown and David R. Woolley in 1973 on the PLATO System at the University of Illinois.
Various type of Chat :-
There are various types of chats available on the internet.
Online chat in a less stringent definition may be primarily any direct text-based or video-based (webcams),
one-on-one chat or one-to-many group chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs.
The expression online chat comes from the word chat which means "informal conversation". Online chat includes web-based applications that allow communication – often directly addressed, but anonymous between users in a multi-user environment.
Web conferencing is a more specific online service, that is often sold as a service, hosted on a web server controlled by the vendor.
1. IRC :~
IRC Stands for "Internet Relay Chat." IRC is a service that allows people to chat with each other online.
Internet Relay Chat (IRC) is an application layer protocol that facilitates communication in the form of text.
The chat process works on a client/server networking model.
IRC clients are computer programs that users can install on their system or web based applications running either locally in the browser or on a third party server.
These clients communicate with chat servers to transfer messages to other clients.
IRC is mainly designed for group communication in discussion forums, called channels, but also allows one-on-one communication via private messages as well as chat and data transfer, including file sharing.
It operates on a client/server model where individuals use a client program to connect to an IRC server.
IRC (Internet Relay Chat) is a protocol for real-time text messaging between internet-connected computers created in 1988.
It is mainly used for group discussion in chat rooms called “channels” although it supports private messages between two users, data transfer, and various server-side and client-side commands.
As of April 2011, the top 100 IRC networks served over 500,000 users at a time on hundreds of thousands of channels.

Advantages of Internet telephony
Internet Telephony offers many advantages compared to traditional telephony as it makes business communication smarter, more flexible, more comfortable and more cost effective.
One of its main benefits is that is allows multiple device integration including smartphones and desk phones. Users can, for instance, access their office extension from their smartphone, giving them complete freedom of communication, no matter whether they are working remotely or in the office.
- Full scalability and flexibility: The best Internet Telephony solutions are hosted in the cloud, so there’s no need for the customer to buy, install and maintain expensive on-premise platforms. Implementation is quick and telephony services, the number of users and any extra features can be scaled up and down as required.
- Lower costs: Typically, IP Telephony is more cost-efficient than traditional landline and mobile telephony. With a cloud telephony solution, internal calls within an organisation are completely free of charge.
- Seamless accessibility and portability: Users can access their Internet Telephony services from anywhere and from any device as long as they have an Internet connection. A dedicated app – such as the Cloudya app from NFON – brings all the functionality of the cloud telephone system onto users’ smartphones, from voicemail and contact lists to call forwarding and conference calls. This makes the switch to mobile working easy.
- Advanced features: With Internet Telephony, voice and data are transported over the same network, making new services possible – such as ‘meet and share’ video calls. Integrations add extra functionality, allowing organisations to streamline all their communication and business processes. For example, Cloudya from NFON integrates with Unified Communications tools such as Microsoft Teams for effective team collaboration.
- Excellent voice quality: IP Telephony has come a long way since it was first introduced in the 1990s. As long as the user has a fast and stable Internet connection with good bandwidth, VoIP calls should experience no latency issues or interruptions. In addition, the latest IP phones and headsets are designed to achieve superior sound quality with noise-cancelling and advanced audio compression, cutting out any background noise.
