The CPU.

1. What is the function of the CPU?
The CPU is the heart of the computer.

2. What was the name of the first CPU?
The name of the first CPU was the intel 8080.

3. Referring to the graph on page 2 of the article, describe how the speed of CPU's has changed:
The speed of CPU's today compared to the older ones is significantly faster. To the point where MIPS ratings lose alot of their meaning.

4. What does MIPS measure?
MIPS measure instructions per second. It stands for " millions of instructions per second".

5. Research what is a dual core processor, what is multitasking and how do the two work together:
A dual core processor is a CPU with two seperate cores, each with its own cache. It's the same as two microprocessors in one.
Multitasking is when you handle two seperate tasks at the same time.
The two work together because the dual core processor has to seperate cores meaning it's multitasking, doing seperate tasks between the two cores.

Read the article about the Intel Atom processor then post about what benefits this processor offers mobile devices:
The benefits are:
- A new range of power-efficient devices.
- Highly integrated application processor.
- Smaller, more compact designs.
- Low power options.
- better performance and increased system responsiveness.

Broadband Research.

1. What is broadband?
Broadband internet access is a high data rate connection to the internet. The superfast speeds mean that whatever you're doing; downloading movies or music, playing games or uploading photos, it'll happen, lightning fast.
2. Outline the methods of delivery (wireless, cable, ADSL and fibre). Identify the speed of each method?
Wireless: Wi-Fi radio systems link up to remote locations over great distances. Compared to hard-wired connectivity there are greater security risks. Speeds are significantly slower (2-50 times slower).
Cable: Cable internet uses the cable television infrastructure which also uses the telephone network. It travels from the internet provider to the end user. About 100 megabits per second for some residences.
Fibre: By fibre-optic cables connected directly to buildings will deliver broadband of speeds up to 100 megabits per second.
ADSL: ADSL service is delivered simultaneously with reguler telephone on the same telephone line. The data speed ranges from about 256 megabits per second to 20 megabits per second.
3. 

	Advantages	Disadvantages
Wireless	- No cords	- Slower speed - Less secure
Cable	- Particularly fast	- Not all cable tv networks are equipped for internet connection.
ADSL	- No dial-up	- Not all phone lines are equipped for internet connection.
Fibre	- High speed	- Cords required.

4. Give examples of broadband providers and identify the costs:

	Wireless	Cable
Optus	12 month contract for 16GB  = $59.95/month	12 month contract, 50 GB =  $49.99/month
Bigpond	12 month contract, 50 GB = $79.95/month	12 month contract, 50 GB = $79.95/month

The World of Multimedia.

1. Where do you commonly use multimedia in your daily life, list as many examples as you can:
    - Mac laptop                            - Work
    - Mobile phone                        - Home
    - iPod                                      - School
    - Home phone
    - TV
    - DVD player
    - DVD
    - Internet
  
2. What multimedia device or service would you find it hardest to be without?
I would find it hardest to live without my phone. but I would also find it hard to live without my iPod and Mac because i need to listen to my music everyday and my Mac i use whenever i am at home. My mobile is probably the most important because i can do so much on it. i can text and call people, i can go on the Internet, take photos and i can listen to music on it. not only is my phone fun to use but i need to have it so I'm able to contact my mum, for safety reason.

3. The video on future directions has already to some extent come true. what multimedia technologies displayed in this video is already commonly used?
In the video the girl on the train does a video call with her friend which is able to happen at the moment.

4. Do you see any disadvantages/advantages to the use of such multimedia technology?

Advantages	Disadvantages
Quick and easy to communicate.	There will be less face to face meetings.
Easy to use.	If something goes wrong (e.g. It’s faulty) there will be a lot of problems because everyone will rely on the technology.
Wide variety of things to do.	Not everyone will be able to understand how to use the advanced technology compared to others.
Easy to access information.	Easier to have an accident while concentrating on the technology in the car.
Doesn’t require much effort e.g. You can just say what you want to happen and it’s all done for you.	Some might not be able to afford it.
