I've been thinking of ideas for my project. At first i thought of making Pong and then i thought of other ideas such as a game where you have to draw lines to make the person run through to the next level, but then i realised that you can't manually draw lines once the game is complete so that idea was crossed off. Another idea is to create a game with levels. It would be some sort of animal trying to cross the road without hitting any cars or trucks and going through the gaps. I also thought of doing some sort of maze game. I don't yet know what kind of game to do yet, but i'm thinking about it.
Now i've decided that i'm going to carry out my plan for building on Pong. I've decided to build 2 extra levels on it that get harder. In the second level i'm making it harder by making to ball go faster. In the third level i will attempt to add in 'powers' such as an extra point or making the paddle get bigger. There will also be bad powers such as a smaller paddle or lose a point. This level will also become harder because the ball will be moving at high speeds and the powers can help you to lose.

Scratch
I have began to use the program Scratch. We played around with it before but now i'm starting the first tutorial for it. At first i found it difficult to work with and i didn't understand what most of the controls did, but after some of the tutorials, i know how to make the sprite move, talk and make them do this for a certain amount of time or even forever.
The second tutorial is Key Moves, this tells you how to make your sprite move in any direction when you press any arrow key. Here the only two blocks you choose are Motion and Control. In this tutorial also i changed the scene of the stage.
Moving Animation is the fourth tutorial which helps the sprite move like an animation. It teaches you how to change your sprites costume and move at the same time.
The fifth tutorial is Say Something. In this one you learn how to make your sprite talk.
The sixth tutorial that I did was Surprise Button, this one lets you add in a button that chooses the sound randomly from the files chosen making it "surprising".
The seventh tutorial is Animate It, this tutorial teaches you how to make a simple animation.
The eight tutorial is Change Colour. It tells you how to change the colour of the sprite by pressing any key.
The ninth tutorial is Dance Twist, it makes you play a sound clip and do a body twist.
Follow the Mouse is the tenth tutorial that teaches you how to make your sprite follow the your mouse pointer and move in any direction.
The eleventh tutorial, Glide, teaches you how to glide from one place to another. It helps to move smoothly without any disturbances.
The last tutorial is Interactive Whirl, this teaches you how to twist a picture out of shape by moving your mouse pointer. Now that i've done all the tutorials and added some snapshots i can start on the challenges.
The first tutorial I did was Keep Score, this helps you to know how to set the variable to a specified number. In this tutorial you use the Variables block. Without this block the tutorial can not be completed and you can't set the score. I also changed the background of the stage to make the situation fit better.
The second tutorial is Key Moves, this tells you how to make your sprite move in any direction when you press any arrow key. Here the only two blocks you choose are Motion and Control. In this tutorial also i changed the scene of the stage.
The third tutorial I completed is Move to a Beat. The tutorial teaches you how to make sounds in Scratch and how to keep the beat. In the tutorial they use a drum and a hand clap to make a beat with a dancer. In this you use the Control, Motion and Sound blocks. The background is also changed.
Moving Animation is the fourth tutorial which helps the sprite move like an animation. It teaches you how to change your sprites costume and move at the same time.
The fifth tutorial is Say Something. In this one you learn how to make your sprite talk.

Broadband Research
Questions-
1. What is broadband?
Broadband is a term that is used consistently with different types of internet connections. Generally, it is referred to Internet connections over fiber optic cables rather than telephone lines. Broadband in telecommunications means a wide range of frequencies that are available to transmit information.
2. Outline the methods of delivery of broadband (wireless, cable, ADSL and fibre)? Identify the speed of each method.
Wireless Broadband is a fairly new technology that provides high-speed wireless internet and data network access over a wide area. In telecommunications, cable Internet access (often called simply cable Internet) is a form of broadband Internet access that uses the cable television (CATV) infrastructure. The fastest cable broadband goes is 300kbps. Asymmetric Digital Subscriber Line (ADSL) is one form of the Digital Subscriber Line technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL offers differing upload and download speeds and can be configured to deliver up to 6 Mbps from the network to the customer that is up to 120 times faster than dialup service and 100 times faster than ISDN. Fibre Broadband uses Fibre Optic cable to deliver data and is able to deliver it faster and also much more of it than can be done with the existing copper wires currently in use.
3. Discuss the advantages and disadvantages of each method.
Advantages of Wireless- Easy to add stations as there are no cables required. Signals can be sent through doors and walls so the stations can be mobile so can move around. There is less need for technical support in setting up due to their simple nature. There are no cables to trip over so there are less health and safety issues to consider. Share resources like printers. Have shared access to a centralized storage.
Disadvantages of Wireless- It's a bit more difficult to setup properly. Risk of 'outsiders' accessing your network unless robust security protocols are enabled (eg WPA, WPA2). Significantly slower than a wired network (2 – 50 times slower). The network can be less stable. Wireless reception may be impaired by a number of factors including large distances or objects between wireless devices, and other wireless networks.
Advantages of Cable- The fact that cable Internet doesn't require a phone line means that you always have a ready connection. Cable Internet is substantially faster than other connections such as dial-up, wireless and ADSL. Cable Internet supports data-heavy activities such as online gaming, so your playing experience will be of higher quality. Because cable is so much faster you will spend less time online.
Disadvantages of Cable- Cable Internet does not always operate at the highest possible speed. Initial connection can be expensive. Not all areas can access cable Internet. Cable may be a wasted expense for those who do not use the internet regularly.
Advantages of ADSL- It is extremely affordable. Internet connection by existing infrastructure. Using telephone line for Internet access as well as for conversation at the same time. Active connection without charging. Internet surfing without telephone impulses charging. Data transfer with download speeds 15-20 time higher than connection speed possible by analogue modem.
Disadvantages of ADSL- The first downside is that ADSL pricing can be very variable. The speed of your ADSL connection may suffer, as ADSL is very affected by physical distance. ADSL is also affected by how many other people are using your line. ADSL downloads much faster than it uploads.
Advantages of Fibre- Fibre optic data transmission is incredibly fast. Fibre optic cables can transmit data over exceptionally long distances without much data loss. Many gaming systems and home theater components now also transfer information back and forth via fibre optic cables.
Disadvantages of Fibre- Fibre optic cables are not susceptible to RF (radio frequency) interference. Fibre optic cabling can cost more than double what a typical broadband connection costs. Fibre optic connections are not available in many areas.
4. Give examples of broadband providers and identify the costs.
Yes Optus- 6GB of data for $30.00 every month. 14GB data for $50.00 every month. 2GB data for $20.00 every month. 5GB data for $59.99 every month.
BigPond- 3GB of data for $29.95 every month. 3GB data for $49.95 every month. 1GB data for $19.95 every month.
Virgin- 6GB data for $39.00 every month. 500MB of data for $15.00 every month. 6GB data for $39.00 every month.
5. The Federal Government is thinking of rolling out a national broadband network (The NBN). Research the NBN and find out:
a. what method of delivery it will use- NBN plans to deliver the best, most cost effective infrastructure across Australia using a combination of fibre, wireless and satellite technologies.
b. the expected speed- NBN plans to deliver fibre-based coverage with speeds of 100 Megabits per second. Premises in areas that cannot be serviced economically by fibre will be connected by advanced wireless technology providing speeds of 12 Megabits per second.
c. the expected costs-
6. Do you think Australians should invest in The NBN? Justify your answer.

Assessment task
For this terms multimedia assessment task, i worked with Vera using the Wix program. My topics were Digital Televisions, Piracy & Copyright, Secondary Storage; Blu-ray Discs & Flash Drives and Bluetooth. In this assignment, we faced many problems. The first one was, when we tried to make buttons that link to other pages of our website, it wasn't working and we didn't find a way to fix it. But just to make the job easier we decided to start on a new template and ask Sir or Miss what to do afterwards. Then the second problem was that the website that we were working on the first time, we had found a solution to our problem. The problem was that we didn't make enough mini-pages to fit our links and then that website began to work again and our other template was a back-up. But this website didn't work for that long because the next time we tried to edit it there was an error saying that the "XML link is incorrect" and we were no longer able to use that website, the solution to this problem was just to start using the draft template once again. After this we had very minor issues and soon after got the website completed. Also on friday the class was given an extension to tuesday. This extension was helpful to me as i had more time to work on the assignment and work on it more thoroughly. Today i finished adding all my information to the website and also made blogposts about the information i researched and the websites i used to get the research. I have done my part of the website and this is the url for the website for now:

Bluetooth
INFO ON BLUETOOTH:
What is it?
Bluetooth is the name of a wireless technology standard for connecting devices, set to replace cables.
What do we use it for?
You use bluetooth so you can connect mobile phones and headsets to your computer, so your bluetooth headphones deliver stereo quality sound without wires, to be able to send photos from your camera to your computer without the need of wires and many more.
How is it part of our multimedia world?
Bluetooth is able to send multimedia from one device to another device without the use of wires and cables.
Are there different types? What are the advantages/disadvantages of each type?
There are no different types of Bluetooth but there is a variety of bluetooth accessories you can get.
A "simple" explanation of how it works.
Bluetooth uses radio frequencies in the 2.45 GHz range to send information over short distances of generally 10metres or less. By embedding a Bluetooth chip and receiver into products, cables that would normally carry the signal can be eliminated.
A rough indication of the cost of the device
Bluetooth doesn't necessarily have a cost because it mainly comes with the device that is bought for example, a laptop or mobile phone. But the many accessories Bluetooth can come in have different costs.
Future directions, what is waiting around the corner, what is the next "new" technology in this area?
The new version of Bluetooth technology will meet the high-speed demands and cater to the needs of low power applications. The next version of bluetooth, also called Seattle, will have many of the same features as the current one but will be capable of very fast data transfer and also being power efficient.

Secondary Storage
INFO ON BLU-RAY DISCS & FLASH DRIVES:
What is it?
Blu-ray Discs (BD) is an optical disc storage medium designed to supersede the standard DVD format. A Flash Drive is a small storage device that can be used to transport files from one computer to another. There are many different types of Flash Drives, such as USB flash drive or solid state drive.
What do we use it for?
Blu-ray Discs (BD) were established to hold a standard-length movie in HDTV format, or high-definition television.The movies are displayed in higher resolution and therefore they require much more storage space. Flash Drives are used for many different things. Because of its small size, many people find them very handy. They are mainly used for Personal data storage, maintenence, law enforcement, boot computers and business uses.
How is it a part of our multimedia world?
Blu-ray dics are a part of our multimedia world as they are able to encorporate many types of multimedia onto the discs. Flash drives are also a part of the multimedia world as they can store as much media onto it as possible.
Are there different types? Advantages/ Disadvantages?
There is only one type of Blu-ray discs. There are two main types of Flash drives, USB flash drives and Solid state drive. The most familiar one is the USB flash drives, this flash drive will let you plug the small drive directly into your computer and you will be able to access it as a drive on your computer. It will allow you to copy information to it as you need to. The Solid state drive is not as popular, and is used to store solid-state data that is persistant.
A "simple" explanation of how it works.
Blu-ray Discs store digitally encoded video and audio information in pits -- spiral grooves that run from the center of the disc to its edges. A laser reads the other side of these pits to play the movie or program that is stored on the DVD. A flash drive is easy to use. Once you have created a paper or other work, simply plug your flash drive into a USB port. The USB port will appear on the back of a desktop computer’s PC tower or on the side of a laptop. When you option to save your work by selecting “Save As,” you will find that your flash drive appears as an additional drive.
A rough indication of the cost of the device
A 25 gigabyte Blu-ray disc costs about $2.60 and a pack of 15 costs $40. The cost of flash drives range from under $10 to over $200 depending on the manufacturer and storage capacity.
Future directions, what is waiting around the corner, what is the next "new" technology in this area?
Since the Blu-Ray disc's launched in 2007, its acceptance as DVD media replacement has significantly increased. Blu-ray has had much support from consumers as well as movie studios and this has greatly contributed to its triumph over HD-DVD. The positives of Blu-ray had people believing, from an early stage, that it would be the future of high definition media. The USB flash drive, a relatively new invention that was first sold in 2001 as a humble 8Mb storage device. Their memory capacity continues to rise while their prices keep dropping. Today a 64 Gigabyte flash drive is not unheard of, and smaller drives can be bought for less than what a stack of blank CD's might cost. WEBSITES:

Today a 64 Gigabyte flash drive is not unheard of, and smaller drives can be bought for less than what a stack of blank CD's might cost. WEBSITES:

Piracy and Copyright
PIRACY AND COPYRIGHT INFO:
What is it?
Piracy is the stealing of others rights such as a book, story, invention or idea. In music, piracy is when you copy a CD or music for your own personal use. To make copies of discs to sell for profit is piracy. Copyright is a type of property that is founded on a person's creative skill and labour.
What do we use it for?
People make pirate copies of other peoples things to sell to other people and gain money of their own to make a profit. Copyright is there to protect the works and labour of a person and prevent unauthorized use of the work that is created by the original person.
How is it a part of our multimedia world?
Piracy and Copyright is a part of our multimedia world because they are both related to media. In the case of Piracy, the person who creates the pirated copy is using media to produce the extra copies. In Copyright, you need it to protect different types of multimedia such as film or music.
Are there different types? What are the advantages/disadvantages of each type?
There are no different types of Piracy or Copyright.
Future directions, what is waiting around the corner, what is the next "new" technology in this area?
Piracy and Copyright have no "new technology" waiting to come out but the avoidance of getting caught for Piracy is reducing and it is becoming harder to produce copies of something that is not theirs.

Digital Televisions
Information on Digital televisions:
What is it?
Digital TV is a term that is used for encompassing High Definition Television and other applications including Standard Definition television, datacasting, multicasting and interactivity. Digital Television is the sending and recieving of moving images and sound by digital signals.
What do we use it for?
The main things we use digital televisions is to recieve better quality pictures and sound quality through digital signal processing. It is also used to introduce new services such as multicasting and datacasting. Digital Tv offers more choice, it is clearer and it can be recieved in many new ways.
How is it a part of our multimedia world?
Digital Televisions are part of the multimedia world because televisions use a variety of different media. This includes true digital and high definition image and surround sound audio.
Are there different types? Advantages/Disadvantages?
There are many different types of digital televisions. The first and most basic type is CRT based or a 'Tube' digital television. These look a lot like analog televisions with a larger screen. If you want to get the most out of the digital television features, such as High Definition television and surround-sound audio, another type would be Plasma televisions. Plasma televisions are very thin, large and look terrific with the sound even better. A third type of digital television is a Rear Projection television. In these televisions the image would come from the back of the tv, meaning it would be thicker with also great high-definition television and surround sound. Another type of television is an LCD television, these televisions have a rich high-definition image and surround sound audio. There is also SD (Standard Definition) televisions which produce a widescreen image with DVD standard quality.
A "simple" explanation of how it works.
Digital Televisions work similarily to a standard television set. Depending on what type of television it is, the way in which it works has little difference. Digital televisions all work mainly the same way, but with a different appearance. Digital television uses a digital signal rather than a radio signal, which allows the picture and sound to appear faster and with better quality. In order get your digital television working, you need to get the satellite cable that connects your tv to the digital signal. The satellite cable is plugged into the tv port and your television is ready to go. Depending on signal strength, you picture will come clearer, faster and in good quality.
A rough indication of the cost of the device
The cost of a Digital televisions depends on what you are looking for. Smaller screen resolution televisions cost from $700-$1000. Larger Plasma televisions cost $2000-$2500 and LCD televisions cost $2500-$3000. 3DTV's are much more expensive depending on whether you buy Plasma or LCD Plasma 3DTV's range from $4500-$5500 and LCD 3DTV's cost $5000+.
Future directions, what is waiting around the corner, what is the next "new" technology in this area?
Panasonic plans to develop televisions that enable viewers to browse the Internet with the simple operation of an easy-to-use remote controller. Stepping out more than 10-15 years into the future, visitors to the Panasonic Center can also experience its Digital Wall. Composed of a large grid of touch-sensitive panels, the wall has tiles to display different applications or to project one larger-than-life video image.

ProtoPage
Our group is not going to use Proto page for our assessment task because it is too difficult to use and it also has many limitations. Also the page loads very slowly and takes too much time to add anything into the page.
Collabarating with Proto page is fairly simple as all we need to do is have one login and not edit it at the same time because we will override the other person's work. This makes it too difficult to do our Assignment therefore we are not using it.

Hand-held Computing
Using the sites below answer the following questions:
http://www.engadget.com/2008/01/10/intel-explains-mid-vs-umpc/
http://www.umpcportal.com/products/
1. What are MID & UMPC devices? How do they differ. List atleast three examples of both types of devices & include images.
An MID is a mobile internet device and a UMPC is the ultra mobile portable computer. The difference between both devices is that the UMPC is a business-class device thats for enterprise users and the MID is a consumer-class lifestyle device. The UMPC runs a "heavy" OS (Operating System) like Vista and the MID runs a "lightweight" OS with a fast startup such as Linux. The UMPC is optimized for office-use things like Excel or Word, whereas the MID is for media playback and websurfing.
Examples of MID: Dell Streak, Archos 5 Internet Table & Huawei Smakit S7
Examples of UMPC: Viliv N5, Archos 9 & Sony Vaio
Watch this video http://www.youtube.com/watch?v=NQgiZd0-DxI&feature=related
and answer the following question:
2. What are the differences between a Notebook handheld computing device and a Netbook handheld computing device?
The screen size of a Netbook would usually be around 7", 9" & 10" but a Notebook's size would be 12.1", 13.1", 13.3", 14.1", 15.4" & 17". The size difference is obvious so the Netbook would be much smaller. But you still get some tradeoff's. Power, Memory and Storage.
The Notebook is running with Vista and it can run XP it has a dual core processor with a large regular hardrive and it can have up to 80 to 320 GB worth of storgae space onboard. The Netbooks usually have very a small storage space, usually 4 to 80 GB sometimes even bigger. The Netbook wouldn't be a place to store a lot of movies or videos maybe only a few pictures, songs because you can play music on it. It wouldn't be a place to put on games or applications, there won't be Photoshop or Word or Excel. The whole point of it is the Net-Centric Computing. For example, sufing the web, checking your email and running web applications. You shouldn't run complex programs on this because it wil run very slowly because of the processor, it has an Intel Atom 1.6GHz (very small and does the basic stuff).
A notebook can do everything a normal computer would do and includes a DVD disk drive. The netbook battery life lasts about 3 to 4 hours and the Notebooks waste their power much more quickly and will only go for about 2 to 4 hours. With Netbooks you can ungrade the batteries which give you 6 to 10 hours of battery life.
3. Using the following sites, describe the design & features of the Apple Ipad then discuss how it compares with a Netbook.
http://www.apple.com/ipad/
http://www.youtube.com/watch?v=MoMo4BcvPbA
With the Ipad there are no usb ports so you can't plug in usb's or other things with a usb cord. However the Ipad has many other features that a Netbook won't have such as applications and very small weight. It also has more storage space included in it.
The ipad has no webcam, no multitasking and no HDMI port and no flash. It is called a purpose filled device, it can watch videos very well and web browsing. The internet speed is much faster and is there to surprise you.
4. Of the three handheld devices - Notebook, netbook & Ipad – which one would suit your needs and why?
5. If I was looking for a UMPC device with a screen size of 10 in or less, which would you recommend? Justify your choice.
6. View some of the videos at this link http://www.umpcportal.com/
How would you envisage students five years from now using one of these devices at school. Select any UMPC / MID device that you have researched that would meet a students needs, justify your choice.

The CPU
http://computer.howstuffworks.com/microprocessor.htm
http://www.intel.com/technology/atom/index.htm
1. What is the function of the CPU?
This is where all computations are carried out before being transferred to memory storage. The CPU accepts input data, processes the information and sends it to the component that is in charge of executing the action.
The CPU, or Central Processing Unit, is the brains of the computer. This is where all the processing of data, computations, and operations are done. The CPU contains the memory, the hard drives, and ports as well that connect all the computer parts and allow each one to function. Without the CPU, one would not be able to do anything with the computer. 2. What was the name of the first CPU?
The first microprocessor to make it into a home computer was the Intel 8080, a complete 8-bit computer on one chip, introduced in 1974.
3. Referring to the graph on page 2 of the article, describe how the speed of CPU’s has changed.
From the table you can see that the speeds of the CPU's have increased everytime a new CPU has been created. From the first CPU called the 8080 it had a clock speed of 2 MHz and the number of MIPS was only 0.64, to the most recent CPU it's called Pentium 4 "Prescott" it has a clock speed of 3.6 GHz and the number of MIPS is more than 7000. From these results you can see that there has been a large change from the first one ever to the most recent.
4. What does MIPS measure?
MIPS stands for "millions of instructions per second" and is a rough measure of the performance of a CPU. Modern CPUs can do so many different things that MIPS ratings lose a lot of their meaning, but you can get a general sense of the relative power of the CPUs from this column. Modern processors can often execute at a rate of two instructions per clock cycle. That improvement is directly related to the number of transistors on the chip and will make more sense in the next section.
5. Research (Google it) what is a dual core processor, what is multitasking and how do the two work together.
A Dual Core Processor is a multi-core processor is a processing system composed of two or more independent cores. It can be described as an integrated circuit to which two or more individual processors have been attached.
Multitasking is the simultaneous execution of multiple tasks (programs) under the control of an interrupt-driven operating system.
Dual-core processors contain two processing cores, residing on one chip, that perform calculations on two streams of data to increase efficiency and speed while running multiple programs and the new generation of multi-threaded software. For end-users this means a significant increase in response and performance when running multiple applications simultaneously. True multitasking allows users to switch from one program to another without always pausing for the computer to catch up and reducing annoying processing pauses.

MIPS stands for "millions of instructions per second" and is a rough measure of the performance of a CPU. Modern CPUs can do so many different things that MIPS ratings lose a lot of their meaning, but you can get a general sense of the relative power of the CPUs from this column. Modern processors can often execute at a rate of two instructions per clock cycle. That improvement is directly related to the number of transistors on the chip and will make more sense in the next section.
5. Research (Google it) what is a dual core processor, what is multitasking and how do the two work together.
A Dual Core Processor is a multi-core processor is a processing system composed of two or more independent cores. It can be described as an integrated circuit to which two or more individual processors have been attached.
Multitasking is the simultaneous execution of multiple tasks (programs) under the control of an interrupt-driven operating system.
Dual-core processors contain two processing cores, residing on one chip, that perform calculations on two streams of data to increase efficiency and speed while running multiple programs and the new generation of multi-threaded software. For end-users this means a significant increase in response and performance when running multiple applications simultaneously. True multitasking allows users to switch from one program to another without always pausing for the computer to catch up and reducing annoying processing pauses.
