ADSL- Provides digital data transmission over the wires of local telephone networks. 256 kbit/s to 20 Mbit/s
Fibre Broadband- By fiber-optic cables connected directly to buildings will deliver broadband speeds up to 100 megabits per second. Australia has already begun rolling out the network over the country using fiber-optic cables to 90 percent of Australian homes, schools and business.

Discuss the advantages and disadvantages of each method.
Wireless Broadband- Advantage: Access internet from anywhere. More devices are able to use it at the same time. Disadvantage: Other radio communication systems may interfere and jam the service. Some wireless broadband systems may be faulty.
Cable Broadband- Advantage: Less expensive. Disadvantage: ...
ADSL- Advantage: Delivers data faster. Disadvantage: Speed may vary because of the ADSL technology.
Fibre Broadband- Advantage: Send data/signals and communicate faster and better with people internationally. Disadvantage: ...

Give examples of broadband providers and identify the costs.
Google- Google Fibre Broadband is said to vary from $4000 to install in one single home.

Telstra- Telstra's ADSL Business Broadband costs $120 for 25GB over a 24 month plan or $240 for 50BG+ over a 12 month plan.

The Fedral Gonvernment is thinking of rolling out a national broadband network (The NBN). Research the NBN and find out:
a) Method of delivery
Using optic-fibres wires, fixed wireless and satellite technology
b) Expected speed
25/5-100/4 Mbps
c) Cost
Upto $99.50/month for 500+ GB

The World of Multimedia

What multimedia device or service would you find it hardest to be without? Discuss.
The device I'd find it hard to go without would be my mobile phone. In more ways then one it "carries" my life in it; alarm to wake me up, reminders, birthdays, memories, songs, planners etc. Like any teenager would know your mobile phone is sort of like your lifeline. It's like a bestfriend that knows about everything, all the sercet photos you keep, the kind of music you enjoy and it always helps you to be on time for things.

The video on future directions (third video) has already to some extent come true. What mutlimedia technologies displayed in this video are already commonly used?
Interactive white boards, Smartphones, Bluetooth, navigation devices.

Do you see any advantages/disadvantages to the use of such a multimedia technology?
Some advantages of developing such technology are making life easier to plan, getting lost a lot less complicated and many more. Although there are many advantages to these new types of technology the disadvantages out-weigh them. With technology evolving rapidly we forget the impact it can have on our lives. Relying on technology to do all the looking, finding, planning and communicating can effect our work environment and social environment. Instead of literally meeting up with people we will be vitually talking to them, instead of getting up and doing actual exercise we will be seating down enjoying a good meal while vibration waves are sent through our bodies by the use of a machine.
