Coming to a Computer Near You
When it comes to computers there's always something new coming out. Here
are a few acronyms you may have heard and some definitions of them:
V.O.I.P. - Voice Over Internet Protocol, this is what's making internet
telephone possible. An article explaining how it works can be found here.
: http://computer.howstuffworks.com/ip-telephony.htm Basically, just as
email and
instant messaging is used to send a text message, VOIP is used to send your
voice over the internet in a phone conversation. Some examples of VOIP
services that could replace your current phone service at home are: Vonage,
Comcast Digital Voice, and for those of you who prefer to not pay for your
computer phone service there's Skype (which also offers free video chatting)
or you could just do a Google search for "
Here is a link to some free services.

H.D.T.V. - High Definition Television is the next big thing in TV
technology. Here is a more detailed explanation of how it works at:
http://howstuffworks.com "HDTV is high-resolution digital television (DTV)
combined with Dolby Digital surround sound (AC-3)." It is a form of DTV or
Digital Television. In the U.S. all TV stations have switched over to
transmitting a digital only signal since 2009.
(http://hometheater.about.com/b/a/212688.htm). In places like Great Britain
the changeover has been underway for a while and in Australia the transition
will be done gradually in 2013. You can view the world-wide progress of the
digital transition here.
WiFi - stands for Wireless Fidelity and it is a form of wireless internet.
For a more detailed definition go here:
http://www.webopedia.com/TERM/W/Wi_Fi.html You may have noticed that WiFi
is being offered for free in more and more places. For example, if you have
a handheld or laptop computer with WiFi you can access the internet for free
at most Starbucks coffee shops and in many airports. Here's a website that
lists free WiFi locations all across the country:
