A) How many people subscribed to the Internet in 2007? How many of these were business use? How many for home use?
In December 2009 the business subscribers were 1 629 000 and the household subscribers were
7 322 000.
B) Look at the access technologies heading. How many more people are using broadband since 2005? Remember that you have to add 000 to the numbers.
2009- 8 951 000
2010- 9 502 000
2011- 10 446 000

Broadband and Bandwidth...
What is a broadband?
Broadband is a fast Internet connection in today's society, but later on in the future there will be even faster Internet connection. So there is no set definition about a broadband because there is no particular limit or a certain degree of standard of broadband.
What units are used to measure bandwidth?
There is no certain agreement made on the ways to prove the terms used to measure bandwidth but the measure that are used now days are bits kilobits, megabits, megabytes (MB), megabytes per second and megabits per second.
How much faster is broadband than dial up?
Broadband is 200 kbs faster than dial up. This means that downloads from the web are faster with dial-up it may even take up to one whole day to download a large file. Broadband has faster page loading as well.
What are the speeds that broadband operates at compared to dial up?
Broadband has a transfer rate of 256 kilobits of data per second and Dial-up has a transfer rate of 56 Kilobits of data per second.
What are some of the advantages of using a broadband connection to download something like a video compared to dial up?
Broadband connection is better to use to download large files like videos, rather than using dial up because broadband is faster and dial up always will have a connection problem when a regular phone line is in use because of the data used. The capacity of bandwidth in broadband is way more larger than dial up.
Create an image in paint that illustrates how a high bandwidth connection can move more data compared to a dial up connection at a given time.

Installing Audacity Sound Editor...
Today I installed the audacity sound editor software on my USB Drive. There weren't many difficulties to install the software, I just basically followed the instructions on the word document. I also asked Mr Cavil a few questions when I was installing the software on my USB Drive. The question I asked him was like the things you do on this software like cutting music or playing two tracks at the same time. Overall there were no problems for installing the software and I also tested the software and it worked perfectly fine. :)

Installing Audacity Sound Editor...
A)What is a portable application?
A portable application is a computer program that you can carry around with you on a portable device and use on any windows computer. Example of portable devices- USB, portable hard drive or ipod.
B)The advantages of portable applications
There are so many different types of software available as portable applications, they are in different categories on the portable apps website. For example in the Internet category some apps that are available are: Google Chrome Portable, Mozilla Firefox, portable edition, skype portable, Iron portable and there are many more Internet apps in the Internet category.

B)The advantages of portable applications
- Convenient
- Free
- Open Platform and Open Source -The entire platform is open source built around an open format that any hardware or software provider can use.

Audio Bit Depth Sample Size and Sampling Rate
1)Sounds move through what medium?
Sound travels in mechanical waves. A mechanical wave is a disturbance that moves and transports energy from one place to another through medium.
2)What unit is used to measure sample size?
Sound is measured in bits.
3)What unit is used to measure the sampling rate?
The rate at which the samples are captured or played back, measured in Hertz (Hz), or samples per second.
4)Compare the quality of AM, FM and Digital Radio?
AM (amplitude modulation)-is a system of radio transmission in which the carrier wave is modulated by changing its amplitude. The operating frequency is expressed in kilohertz (kHz).
FM (frequency modulation)-is a broadcasting mode in the VHF (very high frequency) broadcasting bands. It provides a high quality analogue signal, and is relatively free from static, in which the frequency of the transmitted wave is modulated or varied in accordance with the amplitude and pitch of the signal. The operating frequency is expressed in megahertz (MHz).
Digital Transmitting-Digital radio is the next generation of radio. It is a revolutionary audio broadcasting technology, which dramatically improves sound quality, and will enable you to receive value added radio services for free.
