ICT - Computer system Overview

Computer systems include the computer along with any software and devices that are necessary to make the computer works. The computer will only successfully start up if everything that is needed on the computer is set correctly. If one device in the computer has a problem or wasn’t set properly, the starting up of the computer will show it.

The computer system includes 4 layers - people, network, software and hardware. Hardware is tangible and it makes up the physical computer. There are six components - the motherboard, CPU, RAM, case and power supply. If one is missing the computer will not work properly or you will not be able to start up the computer. 

The motherboard is like the main hardware of the computer, it controls the other hardwires, CPU, RAM... The motherboard is a important part of a computer. The CPU (Central Processing Unit) is like the brain of the computer, the CPU is cover by the heat sink and the fan. The heat sink and the fan help the CPU to cool down, in case the CPU goes over heat. The CPU works with the computer code, the computer will send the computer code to the CPU and the CPU will eventually work out the result. The RAM that is known as the random access memory is a component that allows the computer to send packages. The more RAM there are, the amount of packages sent will increase.

Software of the computer is much different from hardware, there are two kinds software. There are application software and operating software. The operating software is software to operate the computer, for example programs like Windows, MAC OS X, and Linux. The application software are included different types of programs like games, Microsoft, document, spread sheet…

The network system can be extremely complicated, but it can be easy to understand at the same time. The network system is like a spider web that was made out of different connection between computers around the world. A successful network to be made, is when multiple computer that are successfully linked and connected to each other. There are two types of network, the first one is LAN (Local Area Network) and the second one is WAN (Wide Area Network).

The Local Area Network is a Network that has an amount of area that computer can connect with, so if the computer is too far away, the computer won’t be able to connect the other computer. Using LAN can be connected be two ways, it’s either by wired or wireless. Wired LAN needs an Ethernet cable to connect and a wireless LAN will uses radio waves to connect.

The Wide Area Network is a Network that covers a large amount of area, the WAN are often connect with public networks, just like the telephone. Comparing the Wide Area Network to the Local Area Network. The LAN contain a higher speed of connection but a small amount of area, and the WAN contain a lower speed of connection, but a large area of connection.

Lastly the people, there are online community for people to use, for example Facebook, Twitter, Myspace, emails ... These online community are for people to communicate easily with higher technology. With these improvement of technology comparing to the history, the online community are improving from the time. People are using these online applications to share information, chat, mailing and commenting. Looking at the history comparing to now, researching is much more easier. In the past, people's resource for searching are limited, but now people got online resource to use and researching online is much more useful than other types of research resource.

Understanding of internet

In last Wednesday's ICT lesson, we created a role play about how the internet works. We had created a sample of what does the internet looks like with chairs and strings. The packets which is from your PC/Laptop will send through the internet, we created this scene by having people which had numbers to labels their order of which is going first. To make our role play more interesting, we got some packets to be jammed during their were sending to the website they had selected. So they did not arrive to the website at the correct order, but the internet is so strong it can let the packets back in the same correct order to create the picture again in the site.


The internet is like a spider web made by lots of connections in the world.A computer will firstly connect to a LAN (Local Area Network), then connects into the PCCW network. After that PCCW connects to another network which is connected to many other network around the world, maybe AT & T, Singapore Telecom... it depends on what website you are trying to get to. Then you will be connected to the website which you want, for example Google, Facebook, ICHK... When you got on to the site, it will sends packages to your computer so you can get going on the site. Remember this action will only happen in a few second.

Computer Systems Recap

Few weeks ago in ICT lesson, we have been working on some network, hardware, software... basically operated a computer with our own hands.

On the first week we had set into four groups and our aim is to install different part into the case so it could work perfectly again, our teacher Mr.Parker had gave us different parts like motherboard, RAM, CPU, HDD, hard-drive... and then we only need to plug everything back into the correct spot. The parts of the computer are all very important, so if we dropped it. It could cause damage to the parts, the first time we finish was on the second week. We plug in the power supply and the screen, the first time tested doesn't work so we went back and check what had we done wrong. We found out that some part wasn't fully plugged in, so we need to take parts out and replug some wires and the second time worked.

On the third week, we had been trying to connect the network between our computer and computers that other group had made. We need to firstly find our I.P, I.P (Internet Protocol) is a system for addressing computers on the Internet. Then we type in some code in the terminal, terminal is a direct route to sent code to the computer. 

In these few lessons I've learned how to install different part into the computer case, what are the parts for and how to use terminal. Although I don't know when can I use this skills, but I think this knowledge are useful for me to understand more about computers

Media Project: Research of stop frame animation

The video above was a stop frame animation that was made by 6566 photos, the animation had showed a great quality of what do we wanted to do. The video had changed the angle of the camera to show this in a different way and it could show the character that was flying toward the same way, they also added the music at the background to interest people. In this animation, I don’t think he did really well, because I can tell he did the animation in a different time.

My idea of the 30 - 90 second animation is that there will be a man going though his life and I’ll make his day interesting. I’ll make the character walk out of the paper and walk into another paper then this is how he go to his office, and work for a while. On the way back home something interesting happened.

I think I can manage the part where the character is working in his office, because my character won’t have a lots of movements so it could be easier to draw and to take with.

I think the part where the character sitting on the plane would be hard, because if I do that I would need to hang the paper to make it more realistic.

ICT-Media-Video

In our ICT lesson, my group need to create a video about a advertisement about cleaning up in ICT room. We decided to make a video of making object turn alive.

The five tips of being a good searcher

Five Tips of searching information you need easily:

1. Try to search with simple words, get away the unnecessary word.

2. Use less terms, this could make your research much more accurate.

3. Use "" to help your research, for example if you want to search for gold fish. It will only appears with 'gold' and 'fish', but if you put "gold fish". It will give you sites about "gold fish"

4. Try to search the words which you could see in the site, imagine what will come out in the website. 

5. Use ' - ' on your research, if you put this on before the word. (eg. laptops -Apple) If you type this in it will give you different sites about laptops, but not Apple laptops.

Science - Fitness and Health

This is the work I did in my science on heath and fitness, it explain Things I eat daily, foods are healthy in me daily diet and things I do for general fitness on a daily basic.
