Then we click on "Next", we select the option "Private / Non Commercial", accept the license terms and then we install it with the default options.



When the installation is over the program will automatically execute and we'll see a window like the following.



To remote control a computer, we have to writte in the space where it says "Affiliated ID" the ID that appears on the TeamViewer window of the computer that will be controlled, then we click on "Connect with the Affiliated".



After doing this it will ask for the password that appears on the TeamViewer window of the PC that will be controlled, we type that password and then the other PC will be Remote Controled.



With this ends the use of the TeamViewer Remote Controller

Wake on Lan: Turning on a PC through a Network

"Wake on Lan" its a technology that comes implemented in the Motherboard of the PC and that feature allows the computer to be turned on by network pulse.

It works as follows, the computer isn't completely off but it's just suspended, in this way it consumes the minimum of energy without being turned off so by using a software that sends a signal to the Network Card it re-activates itself.

Usage Requirements:

To use the Wake on Lan first of all you ned a Network Card that's compatible with the Wake on Lan function, and you also have to activate the Wake on Lan feature on the BIOS setup of the computer.

> First you have to go to the configuration screen of the BIOS, to enter to it you have to press the F1 key while te PC is booting (It can also be the ESC key or another one depending on the manufacturer)

> When you're in the BIOS, go to the "Power" menu.

> In the "Power" menu you have to Enable the "Wake on Lan" opcion, which will allow the computer to be turned on through the Network Pulse.

> You have to save the changes and exit the BIOS Setup.

After configuring the BIOS to be compatible with the "Wake on Lan", you have to configurate the Network Card, to do this you only have to enable the opcion "Wake on Magic Packet". To turn on the computer you have to send the "Magic Packet", this will turn on the computer remotely, for doing so you need a software that has the capacity to do it (For example the "WOL - Magic Packet Sender" or the "Depicus").

Network Cabling: UTP Cable (Standard 568A, 568B and Crossover)

The UTP cable is the type of cable that is used more frequently on Ethernet Networks and Telephone Networks, it's also the most common used type of cable for Computing Networking. Usually it's used for networks of medium and short distances, it is also the most common one because of its low prices compared to other types of cable (Like Coaxial Cable or Fiber Optic Cable). In Computing, these cables are more commonly used for conneting a computer to a network or to the internet (By using a Modem or other devices, like a Switch)

To make a Network Cable you need the following materials:

> UTP Cable

> RJ-45 Connectors

> Crimp Tool

> RJ45 Tester

Doing a Network Cable

The most common standards for doing a Network Cable are:

> Standard 568A

> Standard 568B

> Crossover

Cable with a 548A Standard

To do this type of cable we have to place the lines of the cable in the correct order, from 1 to 8 in the RJ-45 Connector (The image shows which pin of the RJ-45 Connector is the Pin #1)

The cables lines have to go in the order that the image bellows shows, when the cables are already placed in the correct order, with the Crimp Tool we have to do a bit of pressure in the RJ-45 Connector until it does a little *crack* sound, when it does the sound we have to check that the cable is steady in its position.

Cable with a 568B Standard

In this standard both sides of the cable have to go in the following pattern, after putting them correctly (Like in the 568A Standard) we have to pressure the RJ-45 with the Crimp Tool until it's steady, remember to always check if the lines of the cable are correctly placed before crimping it.

Cable with a Crossover Standard

In this standard both ends of the cable have to go like in the image below, it's also the only type of cable with different ends (That's why it's called a "Crossed" cable, meanwhile the other ones are known as "Straight" cables)

Like the other 2 types of Standards, after putting the cable lines in the correct order and checking that they're placed correctly, we have to apply pressure with the Crimp Tool until they are steady.

Now, after makint any of the types of cables explained before, we have to check if they are correctly made by using the tester, we place both sides of the cable in the connectors of the tester and if all the lights flashes in a green color, it means that they're all fine, but if a light flahes in a red color, it means that the line of the cable that goes into the pins that the tester indicates are wrongly placed.

PC Cleaning

These are the steps to clean a CPU (Internal and External) and a Display Screen (External).

First of all, we have to get the neccesary materials for doing the work, these materials are:

> A little Towel

> 1 "Foam Cleaner"

> 1 “Contact Cleaner”

> A little Brush

> 1 Star Screwdriver

Cleaning the Exterior:

> To clean the exterior part of the CPU (Case) and the Display first we have to put a little amount of Foam Cleaner in the little towel and then rub it over the spaces that we want to clean.

Cleaning the Interior:

> First we have to turn off the Switch that's behind the CPU (This step might not always be posible because not all the CPUs have this switch) after turning of the switch we have to disconnect the CPU while we do the cleaning process.

> First of all we have to unscrew the screws of the Case, so the interior part (Motherboard) will be visible. For doing this we have to use the Star ScrewDriver.

> Then we have to disconnect al the cables that are connected to the motherboard, and with the little brush we start dusting the motherboard.

> We'll start by cleaning the RAM (The part that's indicated with the white arrow in the image below.)

 

For doing this, first we have to move the triggers that keep the RAM held down to the Motherboard, after moving them we carefully remove the RAM, then we have to clean the contact areas with the Contact Cleaner (It is the side of the RAM that goes connected to the Motherboard) also we have to clean the area where the RAM is connected with the Contact Cleaner.

> Then with the same process of cleaning the RAM, we have to remove other parts of the PC and clean them with the Contact Cleaner (Video Card, CD-ROM, etc)

> After finishing with the cleaning, we have to connect everything again and screw the case to it's place, finishing with all the process of cleaning a PC.
