Definition of RSS Feeds?
RSS stands for Really Simple Syndication. It is also called web feeds. It is a content delivery vehicle. RSS is the format used when you want to syndicate news and other web content. When the content is distributed it is called a feed.
What goes in the feed?
You can either have a partial feed or a full feed. A partial weeb wil include headlines, a short summary of the content and a link back to the place where the content resides. Through a partial web you can encourage your readers to click and the read the full article. But there is also the full feed which means that the whole article comes into their newsreader and they dont have to go back to the website at all to get you content.
What can a feed do for you?
It does different things for content recipient and for a website publisher/company. For the content recipient the internet provides us with an access to information at the touch of a keyboard. However it has an awesome amount of information. The get can get updated, and they make it east to keep this flow of information.
For a website published it keeps your audience updated constantly. Feed keeps you in communication with your audience. It is the ultimate content delivery vehicle. News is the perfect content for a feed. For ages 18-54 old age year group internet is the number 1 choice news. Journalists use the internet to reasearch stories. You can update your product news regularly. If the headlines are flashy, chances are they'll quickly open it and read it.
How are feeds different from e-mail?
It is different from e-mail because it is a much secure delivery method. It has a 100% delivery rate, whereas e-mail only has 34%. Emails have heaps of spams and RSS has no spam. You can unsubscribe with a click of a button.
How do people read feeds?
To reciceve a RSS feed you need a newsreaded or content aggregator. There are Web-based readers like Bloglines and My Yahoo. Newsreaders are downloadable and you can install them easily on your desktop, an example would be the PRESSfeed reader, an easy newsreader which can be downloaded easily. Others may include NewsGator, they are avaliable free and paid. Newsreaders have a variety of special features, like combining several related feeds in to a single view, hiding items that you have already seen and categorizing.
How do you find the feeds you want to subscribe to?
They get picked up and published by other websites. Feeds are gainign the attention of the other search engines. Most of the time it come up high in a keyword search and we dont even know we are reading feed content. Feed search engines and blog search engines are everywhere on the net. As people are finding out about feeds they now often look for the little oranfe and gray icons that illustrate that the content is avaliable in a feed. Icon usually says RSS oe XML or simply web feed.

Broadband and Bandwidth!
What is broadband? Broadband Internet access, is usually just shortened to broadbad.
It is a high data rate internet access, typically contrasted with dial-up access using a 56k modem.
What units are used to measure bandwidth?
Bandwidth is usually measured in bits and bytes. A byte is 8 bits.
How much faster is broadband than dial up?
Broadband is atleast four times faster than a dial-up. But usually it is much much faster than dial-up.
What are the speeds that broadband operates at compared to dial up?
Broadband is often called 'high-speed' access to the interent, it is usually 256 kbits/s (0.256 Mbit/s) or even greater whereas dial-up only has a speed of 56 kbit/s.
What are some of the advantages of using a broadband connection to download something like a video compared to dial up?
Some advantages of using a broadband connection to downloading something is, it works up to 100 times faster than dial-up conenction. You can download things in seconds or minutes instead of hours. The internet connection is always on so it is not like the download will be interepted.
A] How many people subscribed to the internet in 2007? How many of these were for business use? How many for home use?
Around 7925 people subscribed to the internet in 2007 and 1295 were for business use and 6629 for home use.
B] Look at the access technoloogies heading. How many more people using broadband since 2005?
Out of the 4.7 million households around 48% had broadban internet access. This grew during the year and it almost doubled with 2.3 million households using broadband internet access.
Check internet speed:
1. What is the speed of the connection from your computer to the Sydney location on the map?
2. What is the speed of the connection from your computer to the U.S location on the map?
3. Why did the data transfer rates vary?

Check internet speed:
1. What is the speed of the connection from your computer to the Sydney location on the map?
The speed connection from our computer to the Sydney location is 0.30 Mb/s (upload).
2. What is the speed of the connection from your computer to the U.S location on the map?
The speed of the connection from our computer to U.S. location is 0.20Mb/s (upload).
3. Why did the data transfer rates vary?
It varies because it takes longer to go all the way to the U.S. whereas for Sydney, its in the same country.

ABUK, JULIE AND I!
Abuk,Julie and I are in one team. We are doing a dance tutorial, Abuk will be teaching the dance to Julie and i will be recording it.
Today we tried to see if it works out, Abuk taught Julie some dance steps on the song say ah...It was hard but Julie and Abuk still tried. It didnt work very well so we will have another next lesson.
:)

New Terms relating to audio files
Stereo: It is a system for reproducing stereophonic sound.
Channel: A path over which electrical signals can pass.
Track: A distinct selection of music from a recording or a compact disc.
Frequency: The number of times a particular type of music or sound occurs.
Hertz: The unit of frequency; one hertz has a periodic interval of one second.
Decibel: It is a logarithmic unit of measurement that expresses the magnitude of a physcial quantity to a specified reference level.
WAV: It is short for Waveform Audio File Format, WAV is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs.
mp3: It is a common audio format for consumer audio storage,also a de facto standard of digital audio compression for the transfer and playback of music on digital audio players.
aiff: Short for Audio Interchange File Format, it is an audio filr format standard used for storing sound data on personal computers and other electronic audio devices.

Introduction to video!
1. The video format we will be using this term is Digital Video, what is the other, older format that was used recently.
Older format of video that was used recently is analog video.
2. Describe the difference between the two formats
The difference between the two formats are that analog technologies record waveforms as they are, while digital technologies convert analog waveforms into sets of numbers, recording the numbers instead.
3. What are some advantages of digital video.
Some advantages of digital video are: learning as moving pictures and sound is more effective than stills. The footage can be updated or changed with ease. They add a whole new dimension to presentation since it can be easily incorporated into computer presentations. Network capabilities, presentations can be distributed rather easily.
4. What is meant by frame rate in video
Frame rate is the number of frames or images that are displayed per second. When a series of pictures is shown to us-humans, the pictures get shown like an animation instead of different images. That is what frame rate is meant in video.
5. Do all applications use the same frame rate, explain your answer
The higher the number of frames playing per second, the smoother the video playback appears to the user. Lower rates result in a choppy playback. As a reference point, film uses 24 frames per second to allow the viewer to perceive smooth playback.
6. What is meant by resolution, how is it measured.
It is an idea that continues to baffle even graphic artists. In terms of framework of editing photos, resolution is a measurement of the output quality of an image. The units used to measure resolution are units such as: PPI (pixels per inch), DPI (dots per inch), LPI (lines per inch), and SPI (samples per inch).
7. What is the colour system called RGB
Red, Green, Blue. These are the prime colours used to make all other colours. Its name RGB came from additive primary colour.
8. Explain the video standards PAL, NTSC, and SECAM, what are the main differences between them.
PAL: Is short for Phase Alternate Line, it is an anlogue television encoding system used in broadcast television systems in large parts of the world.
NTSC: It is named for the National Television System Committee and it is also an analog television system mostly used in North America, South America, Burma, South Korea, Taiwan, Japan and Pacific island nations and territories.
SECAM: It is the french for Sequential Colour with Memory, it is an analog colour television system first used in France.
The main difference between the three is that they are all used in different countries. Another difference is the number of frames per second.
9. Which standard do we use in Australia?
In Australia we use PAL.
10. For what type of video camera would you need to have a Video Capture Card in your computer to download video?
For an analog camera we would need to have a video capture care in our computer to download the video.
11. Why don’t we need a video capture card for the video we will be doing at school.
We dont need a video capture card for the videos we will be doing at school because we will be using digital cameras and mobiles which easily connect to the computer by a cord.
12. What is an IEEE 1394 port
It is a port for connecting devices to your personal computer.
13. Why do digital video cameras use video compression
Video compressions are used to reduce the size of the data in digitized frame or series of frames fo a video/audio. So that it is easier to transfer or send.
14. Describe what a codec is.
Codec is a technical term for compression/decompression. It also stands for compressor/decompressor and codec/decode. All these mean the same thing. A codec is a computer program that shrinks large files and makes them suitable for you computer.
15. What is meant by generation loss, where does it happen?
Generation loss is when the quality and potential increase of file size between subsquent copies of data are loss. Anything that reduces the quality of represtation when copying can be considered a form of generation loss. It is mostly in analog systems, even with the best equipment; generation loss does occur.

Video Idea 1
My idea was to make a tutorial on: how to annoy the librarians??
but Julie found it too boring...so we are not doing this idea, even though it was a great idea in my opinion by Julie didnt like it..so we will think of some other idea...:D
