When it comes down to the importance of an education there is no denying that the longer you stay in school the better off you are when it comes to earning potential over the course of your lifetime. Recent estimates have presented some rather astonishing figures to support these claims however, and I for one think they are well worth mentioning.
Let’s discuss first things first however. A high school diploma will net the average citizen $200,000 additional dollars of lifetime income on average. This is one small baby step when it comes to the educational process however. Some college, even without a degree will even increase that figure an additional $150,000 for a total of $350,000. If this isn’t enough to convince you however try the facts and figures that are associated with the additional earning potential that a four-year degree introduces: $500,000. This addition makes a total of $850,000 more over the course of a lifetime in earning potential. I don’t know about you but I find those figures to be quite a nice motivator for going back and finishing a degree.
While a person’s education may not be an accurate indicator of his or her actual ability it is often used in the business world to narrow down a growing field of applicants for a sadly stagnate number of positions across the country. There are things you just can’t see on a piece of paper and ability and capabilities are among those things. Businesses need a defining factor by which they narrow down the field of potential employees and that defining characteristic is often a college degree in the field of business or a complimentary major course of study.
While this may not seem fair to many who have the practical skills companies are seeking employees that can fill multiple roles in order to eliminate positions that have been occupied in the past. For this reason they want business people who have technical skills and a college education provides a brief introduction to many skills that are useful in these situations. Unfortunately, the only way to know whether or not you have these specific skills is if you list them on your resume while those who have a four-year degree are believed to have them by the merit of their educations.
The earning potential alone should be enough to turn your head when it comes to the importance of earning a college degree though there are many more excellent reasons to pursue the completion of your degree. If you haven’t considered some of the other wonderful reasons for returning to college and getting your degree, perhaps the reasons below will provide a little additional motivation.
1) Challenge. There is very little in life that offers the challenge of returning to college after an absence. It is a frightening prospect for many and yet can be equally as exciting. You will find that the constant exposure to academic debate is a great way to feed your mind and open your eyes to new ideas. Challenge your preconceptions and challenge the limits of your own experiences by opening up your mind to the thoughts and ideas of others.
2) Learn New Skills. There is never a bad time to begin learning new skills no matter what they say about old dogs and new tricks. The truth is that as long as you open your mind to learning you are feeding it and that is a great thing.
3) Career advancement. Whether you realize it or not, a college degree is one of the quickest paths you can take to career advancement.
If the money wasn’t enough to convince you of the impact that a four-year degree can make in your life perhaps the reasons mentioned above were enough to do the trick. Whether or not you realize how much a degree can affect your life the truth of the matter is that it can improve so many things about your life and how you view yourself and the world around you. Now is the perfect time to go back to school and earn your degree.

Bluetooth is easily the best in wireless handheld
technology. When it comes to learning, Bluetooth
can get quite complicated. To help you, you’ll find
the key learning points of Bluetooth below:
1. Bluetooth is an energy efficient, low
overhead communication protocol that’s ideal for
interdevice communications.
2. Unlike infrared, Bluetooth doesn’t require
a line of sight.
3. Depending on the implementation, Bluetooth
can have a range of up to 100 meters.
4. The specification of Bluetooth consists of
a Foundation Profile Document and a Foundation Core
Document.
5. The protocol stack for Bluetooth consists
of core protocols, cable protocols, and even adapted
protocols.
6. The transmitter operates around the 2.4
GHz frequency band.
7. The data channel will change frequency, or
hops, 1,600 times in a second, between the 79 allocated
channels in the ISM band.
8. Bluetooth utilizes a spread spectrum
frequency hopping RF characteristic to ensure that
independant networking operates when the other
devices are in range.
9. A piconet is formed when one or more
devices open up a channel of communication.
10. A piconet can have a master and up to
seven slaves.
11. Communication of the interdevice is
based on the concepts of channels.
12. All Bluetooth devices are capable of
transmitting voice.
13. The channel has a total capacity of
1 MB per second.
14. There are two types of channels with
Bluetooth - SCO (Synchronous Connection Oriented) and
ACL (Asynchronous Connectionless).
15. The SCO channels are time oriented, and
are therefore primarily used for transferring time
critical data such as voice.
16. ACL channels are normally used for
communicating data.
17. Data contained in a packet can be up to
2,745 bits in length.
18. In a single piconet, there can be up
to three SCO links containing 64,000 bits a second
each.
19. To avoid collision and timing problems,
SCO links are reserved slots that are set up by
the master.
20. The masters can support up to three
SCO links with either one, two, or three slaves.
21. The slots that aren’t reserved for SCO
links can be used as ACL links.
22. The LMP (Link Management Protocol)
will handle link level security, error corrections,
and the establishment of communications links.
23. The LMP packets will have priority
over user packets that originate and form the
L2CAP layer.
24. The L2CAP layer will ensure an
acceptable quality of service.
25. No more than one ACL link can exist
at the L2CAP layer.

Have you ever thought about networking your computers at home? If you have a small collection of computers around the house (and a small collection of computer users), you can connect each one of those computers to one another and share data, software, and hardware including a single Internet connection. There are many creative uses for home networking, however it’s an ideal situation when upgrading each computer to the same capability is financially out of the question. On a home network, each computer has access to the equipment of the better machine in the group as if that equipment were their own.
Connecting computers with either an Ethernet cable or a Wireless connection can create a home network. The easiest and cheapest method uses an Ethernet connection, which requires a series of network cards, a cable for each computer, and a router. The network card is similar to the old modems we used in the past to connect to the Internet, however in a home network, it’s used to communicate with every computer that’s connected to it.
You’ll want to first, select the computers that will connect to each other and then install the network cards inside each of them. Then you’ll connect a cable to each computer that will communicate with the server. These cables won’t connect to the server directly. Instead, they’ll connect to the router. To enable Internet access for each computer, this router will need to connect with a modem of the host machine.
Once the hardware is set up correctly (you’ll need to read the instruction manual of your equipment for details), you can then setup the network from Windows on each machine. Within Windows, you can set up a home network similar to the way that you set up an Internet connection. Only this time, you’ll set up a LAN (Local Area Network) connection.
Windows should walk you through setting up a LAN after starting the computer and once complete, you can begin to connect one of your machines to the network. You can do this through Internet Explorer by typing in the address and password required to access the router (the address and password required to access the router will be in the router manual).
Connected to the network, each computer can send files back and forth, open programs on a remote computer, play the sound files and videos located on another computer, and share a single Internet account to browse the web, download files, or chat with someone in an entirely different country. If a single printer is available on only one computer in the network, every connected PC can send documents to it and print them out. Kids will enjoy the ability to play multi-player games and adults will enjoy the ability to blast a single message to everyone at once or maintain a group schedule.
Since we’re describing a home network that will connect to the Internet, you’re strongly advised to install a protective firewall program to thwart Internet viruses, worms, or other damaging spyware code. Firewalls prevent - but they don’t repair. Only anti-virus and anti-spyware programs can reverse damage. So you should install a firewall on the computer that grants access to the computer, and then install an anti-virus and anti-spyware program on each of the remaining computers in the network.
If you have files that shouldn’t be shared (bank statements, credit card information, etc.), you can restrict their access in one of several ways. You can put them in a new folder and then remove the “read” permissions for that folder. Or you can specify who can (and who cannot) access specific files with a password from within Windows Control Panel.
