Flaming: when a participant insults or ridicules another participant.
Spamming: when someone or an organization sends unsolicited and irrelevant messages to a chat room.
Although many chat rooms don’t enforce the rules of netiquette, as you use the Internet to communicate, you should exercise common courtesy and respect as you would when speaking in person with other people.
You must use the same instant messaging software to chat with other users.
Some instant messaging software programs have options for logging on to your chat account using a Web page so you can use the software when you are away from your primary computer.
All instant messaging software programs have some features that work on wireless devices, such as cell phones.
All instant messaging software is free and requires an Internet connection, preferably a broadband connection.

The year 1999 saw the introduction of the first “wireless” connections to the Internet.
Personal digital assistant (PDA): a handheld computer that can send and receive wireless telephone and fax calls, act as a personal organizer, perform calculations, store notes, and download Web pages formatted for handheld devices.
The wireless Internet has expanded to include different hardware devices, networks, and other options.
The conversion from 2G to 3G wireless requires the carriers to invest in technology to make the change.
Many carriers have transformed and upgraded their existing networks by creating 2.5G wireless systems.
There isn’t a single network standard.
A wireless device is manufactured to work only on a single type of network, because different networks use different frequencies in the radio spectrum.
If you choose a wireless carrier with a 2.5G network, for example, you will not be able to receive a signal in an area with only a 2G or a 3G network because your device operates on a different frequency.
3.5G wireless networks use a new network protocol called Universal Mobile Telephone Service (UMTS), which is an extension of the existing W-CDMA network, to provide network connections of up to 10 Mbps.
Wireless fidelity ( Wi-Fi ): a trademarked name of the Wireless Ethernet Compatibility Alliance (WECA) that specifies the interface between a wireless client and a base station or between two wireless clients.
Wireless local area network ( WLAN ): a network in which devices use high frequency radio waves instead of wires to communicate.
Wi-Fi operates in the 2.4 GHz radio spectrum, which is the same spectrum used by cordless phones, garage door openers, microwave ovens, and other devices.
because this spectrum is unlicensed, it is free
the 3G wireless spectrum needs to be licensed

Using Bluetooth technology, you can synchronize and share data between as many as eight Bluetooth compatible devices within the specified range at a rate of up to 1 Mbps.
A collection of devices connected via Bluetooth technology is called a piconet . A piconet can connect to eight devices at a time.
You can use Bluetooth-enabled devices to transfer files, listen to music playing on a computer through a headset, print documents, or connect your notebook computer to the Internet using a wireless phone that is in your desk drawer or briefcase.
Comparing Wireless Network Standards and Bluetooth
WiMAX ( Worldwide Interoperability for Microwave Access ): uses 802.16 wireless network standard being developed for use in metropolitan areas.
Metropolitan area network ( MAN ): provides wireless broadband Internet access via radio signals in the 2 to 11 GHz and 10 to 66 GHz radio spectrum with a range of up to 31 miles and speeds of up to 70 Mbps.
When multiple WiMAX towers are connected to each other, WiMAX has the potential to solve some of the geographical and speed limitations of wired networks and other wireless networks, including Wi-Fi.
There are different Internet resources to chat in real time with friends and business associates
There are different types of wireless networks, wireless network standards, and wireless devices.
When selecting a wireless device, make sure that you understand the features of the network on which that wireless device operates.
Carefully examine the network’s geographic coverage area, pricing options, and the provider’s future expansion plans before selecting the device that most closely matches the functions that you need it to perform.
