ethernet cables

An Ethernet cable is use to connect your computer to the Internet.
To build your own you will need a networking cable, 2 RJ-45 Jacks, and cable cutting pliers.

You first must cut your cable to your desired length.

Then you must strip your wire so that the jack clamps down on the original wire.

Then spread out your wires and going from left to right put the colors in this order:

light orange, dark orange, light green, dark blue, light blue, dark green, light brown, and dark brown.

Once your colors are in the right order, with the clip part facing down put wires in their slots.

Make sure wires are far enough in to make a connection. (you should see the wires at the other end of the jack.)

Use pliers to clamp the jack onto the wire.

Then repeat on the other end of the cable.

When you think you have it right you can plug it into your computer and your Internet and see if you can get a connection.

For me the first time wasn't hard. Once you get one side down you shouldn't have much problem on the other side. Just be careful when stripping the wire because if you cut one of the colored wires you have to start over. I only had to start over once :)

I believe anyone can make these and it could be a lot cheaper so good luck.

networks



A network is a group of interconnected computers. We need a network so we can communicate and function with other people.

A LAN is a local network and a WAN is a bigger geographical network. Information sharing,Hardware sharing,software sharing, collaborative environment.

Three common network topologies are:
Star, bus, and circle.
Client/Server deals with someone helping out someone else. Peer/Peer deals with people just communicating and talking about random things or everyday life.

internet fraud

Second Defendant in Internet Scheme that Defrauded Trucking Companies Sentenced to Federal Prison.

Two 34 year old men from California used a federal Internet site and the U.S. mail to defraud trucking companies of more than $2.7 million. Both pleaded guilty in February to using bogus corporate and individual identities and accessing the Safety and Fitness Electronic Records System(Internet website of the Federal Motor Carrier Safety Administration of the U.S. Department of Transportation). They made up a trucking company and would find places that needed truck loads transported and then hire someone else to transport it for them under a different trucking company but never paid that company. After his partner was sentenced for six years in prison, the other was sentenced to 55 months in Federal Prison and also has to pay restitution to the 300 victims of the scheme.

Blogs

I think the purpose of a blog is so you can share information with family and friends or to people all over the world. A pro about blogs is that you can communicate to people from anywhere who you may not be able to see here at home. A con would be you can get everything to work with blogger and it gets frustrating. They can be safe if you choose not to let the whole world see them but there are ways people can get a hold of your blog. They can be used as an educational tool in that you can learn how to work a blog you can do interactive class discussions on blogger and learn more about the Internet.
