5. The Internet Relay Chat is a protocol used for live interactive
internal text messaging or simultaneous conferencing. It is
mainly designed for group communication in discussion forums,
called channels, but also allows one-to-one communication
messages as well as chat and data transfer including file sharing.
The user runs a program to connect to a server on one of the
IPC nets.
The server relays information to and forms other servers on
the same net.
Once connected to an IRC server on an IRC network, you will
usually join one or more channels and converse with others
there.

9. Designed by ITU (International Telecommunication
Union).
Computer Language used is Binary.
Provides multimedia communications over a variety
of networks.
It is quite complex, possibilities of delay.
Multipoint control unit (MCU), gateway, gatekeeper
(optional) and the terminal are some functioning
components.

13. It lets you connect to the internet without connect to
the ISP or Internet Service Provider. For Wi-Fi to work,
you need:
1. Broadband Internet connection
2. Wireless router
3. Electronic device with wireless adapter/internet card
