Ethernet Cables

The purpose of an ethernet cable is to conect computers to a server or to conect a computing device to something.

You will need cable, wire cutters, and 2 RJ45 jacks.

To wire the Ethernet cable to the computer network, first cut off 2 inches (5.1 cm) of the cable sheath using the wire cutters. Next, untwist the pairs of wires and align them by color. Trim all wires to equal lengths, leaving about a half-inch (1.3 cm) of the wire exposed, and insert the wires into the RJ45 plug, making sure they are in the correct order. Use the RJ45 crimper to crimp the plug, and be sure the wires come to the front of the plug, touching the metal contact in the plug. Now cut the cable, and repeat the procedure for the second RJ45 plug. (COLORS: Light Orange, Dark Orange, Light Green, Dark Blue, Light Blue, Dark Green, Light Brown, Dark Brown.)

You use a wire tester and plug the ethernet cord up to both ends and if it flash's green it works if it flash's green and red it doesnt work.

It wasn't to hard i messed up once, but i got it the second time.

Just keep trying until you get it, its not hard if you know what your doing.

What is the purpose of a blog? What pros and cons do you see about blogs? Are they safe? Why/Why not. Explain how blogs could be used as an educational tool.


The purpose for a blog is for you and everyone else to share information with someone. Pros for blogs i think would be that they are helpful and teach you information you may or may not know, and i dont think that theres any cons about blogs. Blogs are say as long as you dont post personal information about yourself or anyone else. The reason i think there safe is because you cant really get anything useful out of blogs unless someone is telling you about themself or another person. Blogs can be used educationaly because you can post information for schools on them or talk about a project or assingment in a class. Also they can be used to update you on certain events that are coming up.
