The purpose of an ethernet cable is to connect your computer to a network, such as the internet.

1. Get materials
-Networking cable
-2 RJ-45 jacks
-Cable cutting pliers
2. pull cable out of box to desired length
3. strip a small portion of the insulation on the networking cable, about ¾ an inch
4. untwist and spread the wires out
-order of wires (left to right)
-light orange
-dark orange
-light green
-dark blue
-light blue
-dark green
-light brown
-dark brown
5. clip part facing down, you insert the wires in the correct order. Each wire has its own slot
6. make sure the gold on the cables are touching the gold on the RJ-45 jack
7. use the pliers to clamp down the RJ-45 jack
8. repeat steps 2-8 on the other end

Creating an ethernet cable was not hard at all for me. It can get annoying because there are so many places that you can mess up such as that the wires have to be in a certain order. I messed up once by flipping the wires the opposite way they were supposed to go in. I should have been more careful. It is really easy to build a cord, just make sure you double and triple check everything, including the order of the wires.

The purpose of a blog is i guess to inform other people on whatever your blog is about. Blogs are really only good for infomation, but they might not be 100% safe. If you put personal information on it and even if you take the proper security measures theres still a chance that someone might find it. There are extremely good hackers out there that could easily hack into your blog and take some of your personal information. I do not see how blogs could be an educational tool, what are you going to do? You could ask certain questions but there are other methods better than a blog such as blackboard.
