Short for Internet Relay Chat, IRC is a multi-user chat system that allows to people gather on "channels" or "rooms" to talk in groups or privately. IRC is based on a client/server model. That is, to join an IRC discussion, you need an IRC client (such a mIRC) and Internet access. The IRC client is a program that runs on your computer and sends and receives messages to and from an IRC server. The IRC server, in turn, is responsible for making sure that all messages are broadcast to everyone participating in a discussion. There can be many discussions going on at once and each one is assigned a unique channel. Once you have joined an IRC chat room (chatroom discussions are designated by topics), you can type your messages in the public chatroom where all participants will see it, or you can send a private message to a single participant. With many IRC clients you can easily create your own chatroom and invite others to join your channel. You can also password protect your chatroom to allow for a more private discussion with just people whom you invite.

Video Conferencing

Video conferencing is a conference between two or more participants at different sites by using computer networks to transmit audio and video data. Each participant has a video camera, microphone and speakers connected on his or her computer. As the two participants speak to one another, their voices are carried over the network and delivered to the other's speakers, and whatever images appear in front of the video camera appear in a window on the other participant's monitor. Many feel that videoconferencing provides a visual connection and interaction that cannot be achieved with standard IM or e-mail communications.

In order for videoconferencing to work, the conference participants must use the same client or compatible software. Many freeware and shareware videoconferencing tools are available online for download, and most Web cameras also come bundled with videoconferencing software. Many newer videoconferencing packages can also be integrated with public IM clients for multipoint conferencing and collaboration.

SMS & Wireless Communications

Short message service (SMS) is a global wireless service that enables the transmission of alphanumeric messages between mobile subscribers and external systems such as e-mail, paging and voice-mail systems. Messages can be no longer than 160 alpha-numeric characters and must contain no images or graphics. Once a message is sent, it is received by a Short Message Service Center (SMSC), which must then get it to the appropriate mobile device or system. As wireless services evolved, Multimedia Messaging Service (MMS) was introduced and provided a way to send messages comprising a combination of text, sounds, images and video to MMS capable handsets.

Communication on wireless devices such as mobile phones and PDAs Personal Digital Assistant is frequently changing. Today you can use your wireless device to not only make phone calls, but to send and receive e-mail and IM. While you can use e-mail, IRC or IM for free if you have an Internet account, you will end up paying fees to you mobile carrier to use these services on a wireless device.
