Are you suffering from home wireless networking nightmare? There
are so many options. 802.11a, 802.11b, 802.11g – what is all
that? All you want is to get online on your notebook computer in
your living room without tripping over wires.

First thing you should know is, all of them will get you online
or network your computers together. The difference lies in
speed, connection quality and more important today, security.

802.11a offers one of the fastest wireless home networking
speeds because it runs on a much higher frequency that few other
home electronics like phones and microwaves can interfere with.
It can also accommodate more computers connected simultaneously
- which is why more businesses use it since it\’s unlikely a
typical wireless home networking setup requires so many
connections. So this sounds like the perfect solution right?

Yes and no. The high frequency apparently is its worst feature
as well. Many experts will tell you higher frequencies are
easily absorbed and result in shorter ranges. It also means it\’s
less able to overcome obstructions like walls.

That\’s not all. 802.11a and 802.11b are two separate frequencies
so if you have a notebook computer capable of connecting to only
802.11a networks, it won\’t work in a 802.11b setup and vice
versa. But, this is probably one of your least worries because
many wireless connectivity hardware today are capable of
connecting to either one.

802.11b uses a lower frequency. So that expands the connection
range but that also means it shares the airspace with other
electronics and will likely experience much more interference.
On top of that, experts advise that 802.11b networks are weaker
when it comes to encryption and security. Also, as you expand
your range, you\’re also more prone to people trying to crack
into your network from further away and more concealed places.
That\’s certainly an interesting point.

Finally, but definitely not lastly (there are many more 802.11
variations than presented here), is 802.11g. This is somewhat of
a hybrid of the two earlier standards. First it uses the same
frequency as 802.11b so, you get the benefit of a wider range.
Secondly it\’s capable of much faster speeds like 802.11a. The
third plus is it\’s also compatible with 802.11b networks. So you
don\’t have to get new hardware to make connections with an older
network or newer network (depending what you have currently).
And, since it\’s a newer standard, encryption is also better, and
that means you can better secure your home network.

However, 802.11g wireless home networking hardware still costs
more to set up than 802.11a but considering the many plusses it
has going for it, this is at time of writing the best choice for
your wireless home networking setup. Besides, there are plenty
specials going on, prices are coming down rather rapidly for
both routers and network cards.

Is a known fact that every time you open a browser to view a web
page, order something online, or read your email in a web based
viewer that information is stored on your computer for later
use. Whether you are viewing the weather online, reading sports,
catching up on the latest world news or viewing something a
little more private, all that information is stored in your
computer. Windows operating systems store all this material in
what are called Temporary Internet Files or cache. Web pages may
store bits of information about who you are when you visit web
sites in files called cookies on your computer. Your web browser
will store a list of web sites you\’ve visited and places you\’ve
gone in a history file in your computer. Even if you are not
online, programs will store histories of the files you\’ve
opened, played, or viewed.

Generally there might not be any reason to worry about all these
files in your computer, but what if you sell your computer and
all that information is left for someone else to see. Maybe
friends and relatives visit and use your computer and you dont
want everyone to know what files you are running on your
computer. Then you are going to want to know how to delete these
files.

Even if you are not worried about privacy on your computer, you
may be surprised to realize how much hard drive space all this
information takes up. If you are running out of drive space, you
may want to delete these files.

How can I delete these files?

For Internet Explorer 5 and above, you can follow these
directions to clear out temporary files and delete cookies.

1) Open Internet Explorer and click on Tools 2) Click on
Internet Options 3) On the General Tab, in the middle of the
screen, click on Delete Files 4) You may also want to check the
box \”Delete all offline content\” 5) Click on OK and wait for the
hourglass icon to stop after it deletes the temporary internet
files 6) You can now click on Delete Cookies and click OK to
delete cookies that websites have placed on your hard drive.

To clear the Internet History in IE:

1) Open Internet Explorer and click on Tools 2) Click on
Internet Options 3) On the General Tab, in the middle of the
screen, click on Clear History 4) Click OK

To clean up other temporary files on your computer in Windows 98
or higher:

1) Click Start, Programs (or All Programs), Accessories, System
Tools, Disk Cleanup 2) Choose the correct drive usually C: 3)
Check the boxes in the list and delete the files

This deleting method is only good if you want to free space,
because normal file deletion only removes a file\’s directory
entry, and leaves the data contained in the file on your hard
drive, which can be easily recovered by any average computer
user using a undelete utility. If you delete cookies or if you
delete history using conventional methods anyone can recover
them! Even after a hard drive format, files can be recovered
using expensive hardware and software which use forensic latency
track analysis algorithms.

There are several good utilities such as

Ever since the birth of the internet, entrepreneurs with an eye
to the future have predicted that voice communications –
telephone services — would eventually be merged with internet
services. With the widespread adoption of VoIP, that day has
come, and it is causing a revolution in the telephone industry.

In simple terms, a VoIP service allows you to use your broadband
(high-speed) connection to place telephone calls over the
Internet. It is not difficult to see how this is rocking the
telecom industry to the core.

**It\’s all about cost**

Two things have made traditional telephone service providers
like AT&T and Bell so powerful. Their monopoly over local
telephone services, and their traditional stranglehold on
lucrative and usually over-priced \”long distance\” services. Both
of these captive markets have been seriously eroded over the
last few years, as the reality of VoIP has started to sink in.

In anticipation of the revolution that is now upon us, most
aspects of telephone service have gradually been opened up to
competition. Most of us now have a choice of providers for both
local and long distance telephone service. And the biggest
reason for the new competitive environment is the recognition
that the widespread adoption of VoIP is inevitable.

**The development of VoIP**

VoIP has been developing slowly over the last ten years or so.
Early implementations allowed computer users to talk to each
other through their computers. This was only feasible if you had
a voice-enabled computer, a reliable and stable internet
connection, and a software program installed on your computer
that made it all work.

The advantage of this computer-to-computer communication was
that you could completely bypass the traditional telephone
system and talk to anyone in the world free of charge — as long
as they had a similar setup to yours. But the disadvantages of
communicating this way were also obvious. You could only
communicate this way using your computer. You were completely
dependent on often unstable dial-up internet connections. And
the person at the other end of the conversation had to also be
\”online\” with a voice-enabled computer.

**Today\’s VoIP has solved these problems**

Today\’s versions of VoIP have left these problems in the past.
Two things were required to make VoIP technology feasible on a
large scale basis, and both of these things have now been
realized.

First, broadband internet service has been widely adopted. This
makes it possible to have stable internet connections that are
\”always on\”. Second, the industry has developed a simple,
inexpensive method of integrating the IP network (the internet)
with the traditional telephone system. This allows a user of
VoIP to use his or her own telephone to call anyone else in the
world who has a traditional telephone connection.

This is where we are today. As traditional telecom companies
like AT&T, Bell, Qwest, and SBC develop their own
implementations of VoIP technology the way has been opened up
for a myriad of choices for consumers. Today\’s VoIP allows
anyone with a broadband internet connection to place calls to
anyone with an ordinary telephone connection, anywhere in the
world.

**Why you save money with VoIP**

The major advantages of VoIP are lower cost, and greater
flexibility with no significant decrease in voice quality.
First, a VoIP subscriber does not need a traditional phone line.
Instead, you are assigned a phone number by your VoIP provider.
Prices for these numbers can be as low as $9 usd per month.

Second, most VoIP subscribers will purchase a \”bundle\” of
services that includes unlimited incoming calls and unlimited
long distance calls to anyone within a defined geographic area.
For instance, VoIP unlimited calling plans to anyone in the USA
or Canada start at around $20 per month.

Third, most VoIP service providers offer free bundled features
that most traditional telephone companies charge for. These
include free voicemail, call forwarding, caller ID, call
waiting, call waiting ID, 3 way calling, speed dialing, and many
more of the services that the traditional companies are
constantly trying to sell you.

**Greater flexibility and portability**

Another significant advantage is the flexibility and portability
of VoIP phone service. With VoIP your personal telephone number
is programmed into the converter that acts as a bridge between
your internet connection and your regular telephone.

This has several important advantages. As already mentioned you
do not need an actual land line. Instead your telephone number
is assigned to your converter (not to your geographic land
line). So you can take your converter with you anywhere in the
world, plug it into any available broadband connection, and
immediately start using your regular number to make and receive
calls.

This flexibility also lets you choose a number in an area code
where most of your long distance calls originate. For instance,
if many of your friends, family, business associates or
customers are calling from a specific city that traditionally
involved a long distance call for them, you could choose a
number in that area code and immediately turn all their calls to
you into local (free) calls for them.

The advantages of VoIP are many, and the savings can be very
significant. So it is no wonder that VoIP has become the hottest
telecom technology of the decade. Informed consumers and
businesses around the world are adopting this technology at a
phenomenal rate.
