Here's our first test of the year. We have a test on Monday on everything we've learned since the beginning of the year. The things that are going to be on the test are things like the three rules of PowerPoint, all the computer components, how to do a proper PowerPoint presentation and many more.
I'm busy studying on the weekend and hopefully ill do well on the test !
Good luck to you all ! ;)

Seeing is believing.
Ever looked at a computer beyond the image that we can see ?
Well today, I got a good look at what really makes a computer function the way we want it to.
Of course everyone knows that there isn't just a case, screen, mouse, keyboard and speakers to a computer, but do they really know what fascinating things lie behind them ?
To really think of it scientifically, a computer doesn't know anything unless we give it information and instructions. What carries out the instructions and process information are the many different computer parts that are built into the computer itself. Every computer part has its own function, and if each carry out what they are supposed to do, you've got yourself a proper working computer!
Here are just a few of the many computer parts built into the computer:
Motherboard
- everything is connected to the motherboard.
- it controls everything.
- it uses BIOS (basic input output system).
- BIOS wakes the computer up; it stores information so that when you turn on the computer, it can tell the computer what to do.
Video card
-turns binary data from the CPU (central processing unit)
- it takes some of the work that the CPU has to do and does it itself so that the CPU has time to do other things.
- Expensive video cards are coated in gold, but cheaper ones are coated in silver.
Hard drive & memory. (RAM)
- Hard drive is a long term memory.
- It connects to motherboard and power supply.
- It has a lot more hard drive space than RAM
- RAM is what you use right now.
- Every time you open up a program, it uses RAM.
- RAM is like a big table that you use to put and view information.
- USB keys maintain information even if you turn off your computer.
CPU/processor.
- CPU stands for central processing unit.
- It does all the work inside of a computer.
- It is the brain of the computer.
- Its the size of your pinkie.
-There is a fan on top of the CPU that help keep the computer and its parts cool.
- CPU is covered in ceramic which dissipates heat.
Modem.
- Takes binary data and turns it into sound.
- Transfers sound to phone line.
CD-ROM.
- Stores information on the data pads.
- There is a DOT , a laser, that reads your CD.
- While your CD is spinning, the laser moves up from the center of the CD to read it.
- It uses a laser to read bumps and pits.
Mouse.
- There are three types of mouse.
A laser mouse, that uses the reflection of light to send signals to the computer.
A LED mouse, that does the same thing as a laser mouse.
And an optical mouse, that uses two balls for navigation. A fron ball and a back one.
Keyboard.
- Its an input device.
- It is connected to the computer with a cable.
- The cable sends signals to and from the keyboard.
Remember! When you are holding a component, always hold it using the sides and never the top and bottom because there might be some electricity still running.
Until next time,
Peggy

It's such a big relief.
I'm so glad the presentations are over! And hopefully I've done a good job presenting.
Even though we couldn't get to listen to everyone in the class present, because we ran out of time, I still learned a lot on Thursday, about different kinds of computer parts. I learned about RAM, motherboard, LCD monitor and graphics/video cards. There wasn't enough time for me to write down everything, but I managed to learn a lot of information on each computer part.
For our first PowerPoint presentation, I think that everyone did a good job and we all learned many interesting facts.
Hopefully, I'll get better at presenting, and learn from my mistakes so that I can do a better job of it the next time we have to do a presentation.
So long!

If you want to do it, do it RIGHT !
We just finished learning about how to make a proper PowerPoint presentation. We have to turn our posters into a PowerPoint presentation and we only get this class and the next class to work on it. There are many rules to making a good presentation.
- The most important part of your presentation is the presenter.
- Don't read your information off your PowerPoint because you never know what could happen to the presentation. For example: your computer can break or have technical problems or your screen. So your PowerPoint should be assisting you not the other way around.
- Always face your audience when your presenting.
- Don't use flashing lights, moving pictures or text, or sounds because it takes the focus off you and the audience can't focus on what your saying and they'll get distracted.
-Instead of looking at your PowerPoint, use the small computer that's in front of you.
- Always start out with ''Hi my name is ... and today I'd like to talk to you about ... ''
- Its more professional if your tittle on the tittle page is the same font as your sub tittles for starting a new page.
- The minimum font size should be 24. Its better if you use bigger size font so that your audience can see more clearly.
- Always use important jot notes and never write paragraphs.
- Always site where you got your pictures and information from, properly.
- Use clip art for your pictures.
So those are some factors you should consider when you are doing a PowerPoint presentation. And hopefully they will help.

How old do you think you really are ?
On Thursday we learned about Binary codes and how we can switch numbers into binary. At first it was a little confusing but when Mr.Case (my teacher) started giving us examples and making us solve them, we all began to grasp the context. Before we want to turn numbers into a binary code, we have to make a value chart and so that we can identify binary numbers faster. It starts out with 1 times 2, two times two, and you keep multiplying each number by two. The binary numbers are: 2, 4, 8,16, 32 etc.
In binary, base 2 numbers are used instead of base 10. Base 10 is used for normal numbers like: 1, 10, 100, 1000 etc. Base2 numbers consist of only ones and zeros.
See you later!

Not much time left..
Deadlines are here! Today was our last day to finish typing out our project and finishing the poster. We have business tomorrow, which means we are going to start presenting.
I have learned so much from this project and a lot about the computer part I had to research about. I learned the main function of a graphics/video card. A graphics card displays images on a screen. It turns binary data from the CPU and turns it into an image that you can see.
The four main components of a graphics card are:
-A motherboard that is used for connecting data and power.
-A processor which is used to deal with each pixel on the screen.
-A memory to store pictures.
-A monitor to display the final images.
So I put this information plus some more, and some pictures, all together and created a poster that I have to present in front of the class tomorrow to teach them a little about how graphics/video cards work.
Hopefully everyone will learn something new tomorrow!
Catch you later .

First project.
It's not even the second week of school and we already have our first project. But I think it's and interesting and helpful project so I'm looking forwards to learning interesting fact about computer hardware. We all get into groups of two or three and each group gets a specific computer part to research about. Even though we are in groups, we each get marked individually and have to make our own poster. My group has to research about graphic cards/video cards. We are supposed to get information from the site : http://www.howstuffworks.com/ and any other sites that we think might be useful for finding information.
Today in class we got time to take down jot notes on our topic and decide how we were going to do our posters. We have to work quickly and efficiently, though, because we only have until Wednesday to finish them and we present on Thursday!
Best of luck,
Peggy

Just the beginning.
After a long summer, I'm finally back at school and ready to work work work, and learn new things.
I haven't really been interested in writing or reading blogs, but because I took business this year, we're learning to write blogs which I find pretty interesting. Today was my second business class since school started. We didn't do much on the first day, just got a general idea of what were going to be doing this year, but today we all learned to create our own blogs and posts.
Its only the beginning of my year and course but I'm looking forwards to a great school year and hopefully learn a lot of things.
See you around.
