what is a dual core processor, what is multitasking and how do the two work together.

what is a dual core processor?

A duel core processor is a CPU with two separate cores on the same die, each with its own cache.
 what is multitasking?

what is multitasking

multitasking is a method where multiple tasks, also known as processes, share common processing resources such as a   how do the two work together?

how do the two work together

By having multiple processors on a single server, the tasks running on the server can be divided between the processors to allow the system has a whole to function faster.

The CPU

1.       What is the function of the CPU?

The function of the CPU is to perform operations that allow the computer to run.

2.       What was the name of the first CPU?

The first microprocessor was the Intel 4004, introduced in 1971.

3.       Referring to the graph on page 2 of the article, describe how the speed of CPU’s has changed.

The speed, transistors, microns, clock speed, data width and MIPS have all increase a significant amount since model 8080 to model pentium 4.

Name	Date	Transistors	Microns	Clock speed	Data width	MIPS
8080	1974	6,000	6	2 MHz	8 bits	0.64
8088	1979	29,000	3	5 MHz	16 bits 8-bit bus	0.33
80286	1982	134,000	1.5	6 MHz	16 bits	1
80386	1985	275,000	1.5	16 MHz	32 bits	5
80486	1989	1,200,000	1	25 MHz	32 bits	20
Pentium	1993	3,100,000	0.8	60 MHz	32 bits 64-bit bus	100
Pentium II	1997	7,500,000	0.35	233 MHz	32 bits 64-bit bus	~300
Pentium III	1999	9,500,000	0.25	450 MHz	32 bits 64-bit bus	~510
Pentium 4	2000	42,000,000	0.18	1.5 GHz	32 bits 64-bit bus	~1,700
Pentium 4 "Prescott"	2004	125,000,000	0.09	3.6 GHz	32 bits 64-bit bus	~7,000

4.       What does MIPS measure?

 MIPS stands for "millions of instructions per second" and is a rough measure of the performance of a CPU

Broadband Research

1.      What is broadband?

 broad band is telecommunication signal which has a high data rate connection to the Internet

2.      Outline the methods of delivery of broadband (wireless, cable, ADSL and fibre)? Identify the speed of each method.

wireless- The speed of the wifi connection really depends on the range of the modern to the wirless connection and how many gigabites you have when accessing the internet. (Traditional 802.11b was licensed for omnidirectional service spanning only 100–150 meters)

cable-bit rates can be as much as 400 for business connections, and 100 for residential service

ADSL- ADSL ranges from 256 kbit/s to 20 Mbit/s 

fibre-  fiber-optic cables connected directly to buildings will deliver broadband speeds up to 100 megabits per second.

3.      Discuss the advantages and disadvantages of each method.]

wireless-

Advantages:

cable-

Advantages

• ASDL broadband is much quicker
•   Another advantage is that broadband uses signals that do not disturb the normal phone signals
• Broadband is, in general, an 'always on' connection which means that it is always connected and ready to go.

Disadvantages:

• It requires a fixed physical connection between the source and destination and therefore does not support mobile applications.
• It is usually costly to install.

ADSL-

Advantages:

• ADSL has the advantage of a dedicated amount of bandwidth, but is affected by the distance from the Central Office.

 Fibre

• ItIt can cover greater distances more reliably than wire
• It can handle greater speeds, e.g. 1000Mbps and upwards
• It can not be compromised by signal tapping

Disadvantages:

• It is not as robust as wire
• It is more expensive to buy
• It is more expensive to install
• It has be installed by specialists

  Advantages:

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

ADSL broadband ( broadband only )

12 months

• Implementation cost is cheaper than wired network.
• Ideal for the non-reachable places such as across river or mountain or rural area.
• Ideal for temporary network setups.

Disadvantages:

• Lower speed compared to wired network.
• Less secure because hacker's laptop can act as Access Point. If you connected to their laptop, they'll read all your information
• More complex to configure than wired network.

THE world of multimedia

1.      Where do you commonly use multimedia in your daily life, list as many examples as you can.

While at home:

- ipod

- computer

- tv

- phone

In the car

- radio

- ipod

-Phone

2.      What multimedia device or service would you find it hardest to be without? Discuss.

I believe that i would find it hard to live without wifi. If i didnt have wifi i wouldnt be able to connect to the web and talk to my friends ( social), and see what is happening around the world. If i didnt have wifi i would be bored and have nothing to do.

3.      The video on future directions (third video) has already to some extent come true. What multimedia technologies displayed in this video are already commonly used?

The smart phone, connecting to people around the world, touch screen. voice control,

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

 I see a big advantage in the advance of this type of technology, this technology would enable us to do things faster and without complication.
