Using Scratch

Today i had an attempt on scratch. I am starting to get used to how to use it and it is very interesting. Below is an image which i print screened to show what i had done on scratch. The stick figure i created moved and sound came. This is only a simple and plain image i had created.

Step Two - Scratch and Programming Control Structures




Above is the prinstscreen of the "IF" and "FOREVER" controls i experiemented for the last section in part two.

Step two - Flowcharts

1. For each of the flowcharts below describe in words what you think they will do.

 a)

The flowchart above describes how temperature is shown. Once the termometer is turned on, you read the temp and if the temp is below 32 degrees celcius it will print "Below Freezing" if it is not below 32 degrees celcius it will print "Above Freezing" and then it will end.

b)
The flowchart above describes what the responses are when a light is switched on. Once you press start, if the switch is on then the LED will turn on, however if the switch is not on it will keep asking whether the switch is on. Once it is on, the LED will turn on and the timer would start. If one second hasn't expired the timer will keep asking if it's started, however when it starts the LED will turn off and the timer will reset. The process will be ended here.





2. Convert one of the algorithms you have created in the previous task into a flowchart, e.g.  opening a door, moving through a traffic light.

Step two - Computer Algorithms


DEFINITIONS
1. Algorithms
In its most general sense, an algorithm is any set of detailed instructions which results in a predictable end-state from a known beginning. Algorithms are only as good as the instructions given, however, and the result will be incorrect if the algorithm is not properly defined.

2. Pseudocode
Pseudocode is a compact and informal high-level description of a computer programming algorithm that uses the structural conventions of a programming language, but is intended for human reading rather than machine reading.

3. Machine Language
Machine code or machine language is a system of instructions and data executed directly by a computer's central processing unit.

4. High Level Computer Language
A high-level programming language is a programming language with strong abstraction from the details of the computer. In comparison to low-level programming languages, it may use natural language elements, be easier to use, or be more portable across platforms. Such languages hide the details of CPU operations such as memory access models and management of scope.

5. Flowchart
A flowchart is a type of diagram, that represents an algorithmm or process, showing the steps as boxes of various kinds, and their order by connecting these with arrows. This diagrammatic representation can give a step-by-step solution to a given problem. Data is represented in these boxes, and arrows connecting them represent flow / direction of flow of data.

6. Sequence
In mathematics, a sequence is an ordered list of objects (or events). Like a set, it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence. A sequence is a discrete function

7. Selection

The act of choosing or selecting. ('If' or 'Then')
8. Repition
The act or process of repeating a set or sequence of instructions.


ALGORITHMS

a) Opening a Door and Entering a Room
1. Position yourself in front of the door
2. Lift your hand slightly
3. Rest your hand on the door knob
4. Twist in a clockwise direction and pull
5. Release the door knob
6. Walk straight forward through the door
7. Enter the room

 b) Traffic Lights Algorithm
1. Approach lights
2. Check colour of light
3. If the light is green, then continue driving
4. If the light is red, then prepare to stop
5. If the light is orange, then slow down

Broadband Research

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.

FINAL WIX WEBSITE !

here is my final webpage, enjoy :D !

Assignment

Overall, using wix to create my website was definately a success for me, because the site was not only easy to use, but also made a page that was aesthetically pleasing. Wix made making a webpage a challenge for me because there were too many opntions to choose from, making it hard to choose what i wanted and how i would have liked to set out my Multemedia project webpage, although it is actually an advantage of the site, giving an advantage to the user for a variety of choices. The amount of choices of layout made on my webpage, made it more iteresting because every page had a different setting, creating a change and diversity between every page. Wix also has mini pages which i used affectively in my presentation i think because i added things such as mini pages inside mini pages and made it organised but still informative.
Another issue that nearly every user of Wix had to face was to wait for a long period of time for the page to load, which confused me because when i tried the other websites toc create my webpage it didn't lag or i didn't had to wait for a long time for it to load/save. So, waiting was an issue i faced.
Overall i found wix pretty enjoyable and fun to use. In the beggining i found it difficult to use, however now that i am aware of how to use it and how it works it is much simpler and easier to use. It is also helpful for me as i would love to use this webpage in the future if i need to make a presentation for something because now i'm sure how to use it and don't find it difficult.
If i had the opportunity to re-do my webpage, i would have used my time wisely spending the same amout of time and effort in every page, instead of putting soooo much effort into the first few pages and then rushing through the last pages in order to meet the deadline of the due date.
I feel very proud of the work i have done through Wix, and i am planning to use this knowledge in the future, to maybe present in class to replace powerpoints.  I also learnt new techniques  and information about the whole world of multimedia, including the different types of multimedia., some stuff that i didn't know of before and also about the future of multimedia. How nothing is staying the same, over time technology is becoming more compact and is having more storage place. Can't wait for what's soon to come out!

Bye ! :)

information - Bluetooth & Cpu's

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.

CPUs

What is it? What do we use it for?
The CPU, commonly known as the Central Processing Unit (microprocessor), is the heart of any computer whether it is a desktop machine, a server or a laptop. It is the primary element in carrying out the functions of a computer and reads as well as executes program instructions.
How is it a part of the multimedia world?
CPUs are an important and major part of our multimedia world as we frequently interact with them and they respond to our every command. They are some of the most common devices used worldwide and are embedded in every computer. Without CPUs, performing some the simplest operations which we do today, would be impossible as they are the heart of computers and play a large role in our modern multimedia world.
A SIMPLE EXPLANATION...
 The CPU is situated in the motherboard and all other hardware components and programs installed on the system must go through the CPU before their function is carried out. When a function, program or piece of data is selected, the CPU retrieves this information from the Random Access Memory (RAM) or any other software, in order to process it.  The CPU then reads the command associated to the task and sends it back to the RAM. All data and information must travel to the CPU before the task is executed. The CPUs job is to ensure that the data is guided through the system, to be processed and before the next step is taken. 
COST
 The costs of CPU chips vary according to their level of performance and abilities. The prices range from $50 (cheapest) up to as much as $2000. Improvements have been made to these very minute cards which withhold large amounts of information and perform multiple, complex tasks.
DIFFERENT TYPES
 Two different types of CPUs include the Dual Core Processor and the Intel Core.
The dual core processor consists of two separate cores on the same chip and this is equivalent of tow microprocessors in one. This is advantageous, however, when excessively multitasking, the processor must keep alternating between two or more sets of data streams or programs. Thus, the CPUs resources are depleted and the performance suffers.
The Intel Atom is another type of CPU and the main advantage is that it uses the least amount of energy and is also quite cheap. However, the down side is that the Atom is mainly used in Netbooks and is used for basic computing. They are quite slow and do not compare well with the performance of the Core 2 Duo or the Pentium Dual-Core.
FUTURE DIRECTIONS...
 As the years pass by, many new improvements are being made to CPU chips and results might just bring us to the next level in technology. Overall, general stability enhancements are being made and alterations continue to proceed. There are some short term goals in place, however, other features may take years to be established and completed.

WIX overall first evalutation

Overall i find wix pretty enjoying and fun to use. At the start i found it difficult to use, however now that i am aware of how to use it and how it works it is much simpler and easier to use. It is also helpful for me as i would love to use this webpage in the future if i need to make a presentation for something because now i'm sure how to use it and don't find it difficult.

Wix website ..

My wix assignment yhas been going great, i have done my research for 3 of my topics:
- Digital Television
- Piracy and Copyright
- CPUs
I only have the research to do for bluetooth then all my research would be completed

At the moment i am working on making my website pretty and filled with attractive items, most of my pges are going well as i have also found some youtube videos to add to my information. I have added many animations and am enjoying this assignment as wix is fun to use.
we have all received an extension till tuesday.
I don't think i will need most of this extension as i am close to finished, however i may need it to evaluate my final project and add some tocuhes to my wix website.

I beleive i have used my time wisely as i am not stressed about this assignment, however i'm going through this assignment calmly.
I am now going to go and add more stuff to my wix website, and go through the checklist miss has made for us incase i havn't done something. This will let me know if i have completed my assignment fully and use my extension days to add anything extra to my page which i have missed.

Information - Social Networking

What it is? What do we use it for?


Social Networking is a means of communicating with family, friends and relatives all around the globe. It allows users to share multimedia information such as images, videos and many more and is the most efficient way of keeping in touch.

How is it a part of our multimedia world?

Social Networking sites make up an enormous part of our multimedia world as they consist of videos and images which can be viewed through the use of a computer, laptop or even phones or iPods.

Are there different types? What are the advantages/disadvantages of each type?

There are various different types of social networking sites that are available to our society today. Some of the many common ones include Facebook, YouTube and Skype.

Facebook is an extremely popular site used by millions around the world. It allows users to share information conveniently and almost instantly, and thus, is a simple way of keeping in touch. It allows private and general conversations and sharing of multimedia. However, there are some security and privacy issues that occur frequently and it is not always considered safe.

YouTube is a website specifically used to share multimedia in the form of videos. This is a website used for entertainment and amusement that is very convenient and videos are viewed by millions. Movies and television shows can be watched, however, there are some issues with privacy. It is also quite addictive and some videos are quite inappropriate.

Skype is a commonly used social networking website which allows video-conferencing. Family and friends can be contacted almost instantly and be seen on the screen. However, quality of sound will suffer during the call, especially if the internet connection is poor. Also, sharing photos on Skype is problematic as it takes an exceedingly large amount of time to be transferred.

A “simple” explanation of how it works.

In order to use social networking sites, a computer (or laptop) and internet connection is required. Each site varies as they all have different purposes. Facebook is designed for the sharing of messages (both private and general), videos and photos however Skype is mainly designed for video conferencing. Also, when video conferencing using Skype, video cameras are required by both members who wish to communicate. Social networking sites are generally used to post images, videos and information about yourself in order for friends and family to view.

A rough indication of the cost of the device (only where a device is being researched)

Social Networking websites such as Facebook, YouTube and Skype are free of charge and available to everyone to use. However, some sites require you to pay in order to use them. Free social networking sites make money to support millions of users through investments from venture capitalists. These are funds made available for small start up firms with exceptional growth potential.

Future directions, what is waiting around, what is the next “new” technology in this area?

The future of Social Networking and the long term success depends on the ability of the sites to retain the interest of their members. Already, the number of users have been maximised since the introduction of social networking sites being used on phones and iPods. The next step regarding social networking relies on the websites’ ability to entertain and engage their users. If this is established, it is predicted that many improvement would be made to existing websites and new ones would be created to enhance the ability of the site.

Digital television information

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.

working on assignment in class...

throughout these lessons i have been working on my assignment. i have finally chosen wix for sure, and have started making new pages. i tried many samples however i couldn't find one which best suited me. I finally came to a conclusion, and found the website i liked. I am now well into my project. i did have some difficulties to find the animations and set out my page, however with some help of "wix help buttons" i found ways to solve the problem, the video tutorials helped me.
I am now researching for the information which will be on my page. i am aware of what my blog would look like now i need to get pictures animations and information onto the different pages.

WIX

I have now decided that i'm going to use wix as i find the animations and colour schemes and effects affective.
At the start however, i found some difficulty with the menu bar as the whole word of my topic wouldn't come up.

WIX

This is my wix website:

www.wix.com/simrandhillon

11/08/2010. Trying different websites

Dear blog :)
Today i tried two of my favourite websites, wix and jimdo. I found jimdo easier to use rather than wix as it is simpler. However wix has more animations and makes the website look flashier prettier. The one thing i didn't like about both the websites was that wix was difficult to use as there are too many editing features and jimdo loaded the features too slow. These were the difficulties i encountered.
I am most probably going to use wix as it makes the page look better, however if i find it too difficult to do i will have to chang to jimdo.
