Eithernet Cables


The purpose of a/an ethernet cable is to connect two network devices through ethernet.
The materials needed to make an ethernet cable are the length of network cable that you might require, (2) RJ45 jacks, and cable pliers/cutters.
To make an ethernet cable you first cut the wire to your desired length, strip the blue tubing without cutting the wires inside, then you untwist the colored wires, place the colors in the correct order;
light orange, dark orange, light green, dark blue, light blue, dark green, light brown, dark brown. Then you cut the wires to make them all even lengths, hold the clamp down with pliers, and then repeat steps 2-9 on the other side of the cable and then test the length of cable for internet connection to see if the wires are touching the correct jack slots.
You test by putting both jacks into the connection tester and turn it on.
-If green lights appear, you have been successful, otherwise you may need to start over and make sure you find where you went wrong.
When i put my eithernet cable together it wasnt that hard seeing that its not hard to work with tools that are as self-explanatory as the eitherenet connector tool was. i figured i would atleast mess up once but i took my time and got it right the first time.

WAN's & LAN's


list the four benefits of using a network Defferentiate between WANs and LANs. Identify atleast three common network topologies. Insert an image from the web of each. List four examples of network operation systems software. Describe the difference between client/server networks and peer to peer networks.

they allow users to access programs and data at the same time, the allow users to share peripheral devices such as printers and scanners, they make personal communication easier, and they make it easier for users and administrators to back up important data files.

WAN's are two or more LAN's connected together generally across a wide geographical area, and LAN's are a network of computers that are relatively near each other and are connected in a way that enables them to communicate.

Blog(ing)?


Blogging... i am not much of a computer person myself, especiall being on for hours at a time. So personally im not too fond of it; but i am seeing the benefits and positive side of blogging. It seems to be a good way to keep in touch with people you dont see often and whom have a hard way to communicate with you. I also think that it can possibly be addicting yet fun at the same time so i am going to keep an open mind.
