Take Power sources out of lap tap, then drain power before upgrading memory. Make sure you put it in a bag.  then slide in the new memory by only touching the corners. There are little clasps that click it into place. There are many ways to test memory. POST is one. This will detect new memory. Memtest86 is one type of test.You can also get one from Microsoft(website). This was very interesting to look at. If we want to upgrade a compuer with memory: we can see if there is something special on the memory we need. Some websites will do this for us. Mrs. Happy showed us a website called crucial.com This let one know how much memory they needed. She also showed a table of different Memory Types. Ex: RAM, CMOS, ROM, PROM, EPROM, EEPROM, and FLASH. ECC corrects problems.
Then we looked at Task Manager. Then we could check what we wanted to see. This is a useful utility, that people don't realize. Memory Symptoms: you can have an error message. The computer can also randomly crash.
Then she got into Buses inside the CPU.  There are 4 types.
1. Address Bus.
2. Data Bus
3. Expansion Bus
4. Video Bus

Okay, so today we talked about BIOS and the Mother Board. We can change the date and time in the BIOS. When you flash the BIOS you have to make sure that it is in complete order. Never reboot the computer when you update the BIOS.The first thing that she talks about today is how to update your BIOS.  One of the biggest problems with BIOS is the fact that it sometimes makes the the hard drive inaccessible.  Another issue would be having the wrong date and time on the computer.  One should remeber to only update the BIOS when it absolutely needs to updated.  The motherboard is actually run with a battery.  When this battery is removed or it runs out of power, it resets the computer back to default.  Computer performance is rated in million of intructions per seconds or MIPS.  There are also many different cooling methods for computers.  The most common cooling system is called fins.  Another method would be a fan that would go inside the computer itself.  Fans can also be on the outside of the computer itself.  One of the most important things to remeber with a computer is to have to tower positioned so that it will get enough circulation for the fans.  This way the computer won't meltdown and stay cool.  To upgrade the BIOS, it is wise to go to the manufactureres website and update it from there.  The next subject discussed was memory.  Memory on computers is known as RAM or random access memory.  Quality RAM is critial to computers.  When replacing memory it is important to rember how to install it.  The new memory has to be put in at a 45 degree angle. MY STUFF ERASED WE TALKED ABOUT THE SAME STUFF I APPOLOGIZE!!!!!

Starting Point: 1.7 Static

Static is caused by different things. We are always supposed to unplug the cords. Then drain the power. The power supplies were interesting. She showed the power supply box. It has alot of different wires in it. Then she talked about Installing a Power Supply. We have to turn off the pc, disconnect power etc. Then we looked at different connectors. She spliced a wire and showed us the different colors of wires. She connected the wire to the mother board. Protecting your equipment is vitally important. To start with we looked at battery backups. She used a UPS. We look at how much battery power it had or needs. Different things will happen and then you can troubleshoot. Electricity is deffinitely important. Learning how to protect your equipment is something you should always do! You can tell these steps are important and will help you in the long run.

Ms. Happy talked  first about Windows Explorer. It's a very powerful utility! The root folder had hidden folders and she showed us how to enter and see the files. She also talked about copying folders. We are able to copy somehing like a folder and copy it as many times as we like. The recycling bin is a holding place for all things we deleted. You can empty it and make sure what you deleted was what you wanted. She just told us about different file extensions such as .bat, or .bin etc. A batch file is a series of commands at one time.  she told us about a lot of them. File limits are like you have 8.3 Eight characters for the name and 3 characters for the extension. Seperated by a period. Windows has a 255 character limit. With the Attrib command she showed different key terms and what they do. On Note Pad she showed us different abilties on it. How to save documents you made on the application. Then she went into a whole review of the chaper. Like to troubleshoot, security, firwalls, software management, hardware support, and then moved into assistance utilities.

Starting Point: 1.22 Demo: Windows XP Professional and Computer Management.

Mrs. Happy Showed us how to see if we had someone in shared folders to see if they are working on something. We toured different tools in Computer Management.
The we talked about the Command Promp. We first go to the Run menu, becuase there is 2 different ways to open a command promp. First you can type in Command or cmd. DIR tells what is in the instructors folder. Also, I learned what different codes do in the Command. We can control many different things. for example: C:\>dir/ah is where you see hidden files. She also showed us how to scroll up and pause it so we can read it. Overall= Great day!

Starting Poing: Networking features
Ms. "Happy" talked about network wizard. How to set up a shortcut to get to it too. She showed all the different options as well. How to set up and run the different options. She talked about file and server security. A roaming profile is where someone is constantly on the same computer. Others may use different computers. Then we looked at the security policy. It is in the control pannel and then into tools. Then we went to the local secrity policy. Acount policy was the first thing we really looked at. She showed me what to do with the passwords and the different options we can change. For example: when to change your password, how many days before you have to change your password, who is able to get on the computer etc.

Starting Point: Mac OS X.

We first explored macs and what some of the programs are. A downfall to having a mac is  because you might get a newer version of a program. But it might take some time to get downloaded onto all the macs out there. She also mentioned a Linux which is a Windows based graphic user. One is able to download it for free and it will run on most Pc's. She also went over some terms and explained them along with talking about security on your computer. She told me that we need to get a virus protection on your computer. Also how to let some programs have a pass to the security. She also talked about trouble shooting the computer. It helps to fix a malfunction with your computer.
