Music in your pocket

The iPod is no ordinary music-player; it has developed into a symbol of our day. It has become a fashion item of children of all ages, adding to their “image”.

The sales of this digital favourite exceeded all expectations. Between July and September 2004, two million iPods were sold over the counter. At Christmas sales were expected to reach ten million. As far as looks are concerned, iPods are considered as cool as hell, both inside and outside.

The iPod Photo has space for 15 000 songs on its hard-drive of 60 giga-bytes and it offers you the possibility of photo displays.

The iPod mini is exactly what the name suggests: smaller, lighter and thinner than its elder brother, but less powerful. Its battery needs to be charged sooner, and it can store only 1 000 songs on the hard-drive of 4 giga-bytes.

In the meantime other companies, following in the footsteps of Apple who developed the iPod, have come up with their own models. Dell brought the Digital Jukebox onto the market. Philips produced the HDD and Packard Bell the Pocket M@estro. The latter is hardly bigger than a credit card, with a hard-drive of 5 giga-bytes and a built-in FM radio transmitter and a dictaphone as well.

Philips’ ADD 120 however, has lost out, because this model was slow and cumbersome to handle, and came with useless earphones. Besides, it was much more expensive.

The Internet-shop iTunes Music Store sells more than four million songs per week, bringing the provisional total to about 200 million. Impressive, to say the least, even if the figure does not mean much compared with the 150 milliard songs that have been down-loaded illegally during the previous year, via filesharing services such as Kazaa, Grokster and eDonkey. However, the results of iTunes Music Store are encouraging, as it proves that consumers are actually prepared to pay for their music. Customers pay about R10,00 per song, and they seem to regard it as a reasonable price.

  • How do the price compare with those on the Internet?
  • Now what?


Learning Outcomes(LOs)
LO 3
MANAGERIAL, CONSUMER AND FINANCIAL KNOWLEDGE AND SKILLSThe learner will be able to demonstrate knowledge and the ability to apply responsibly a range of managerial, consumer and financial skills.
Assessment Standards(ASs)
We know this when the learner:
3.3 describes the importance of administration in managing a business (record keeping, storing documentation);3.4 discusses the use of technology in telecommunication services (e.g. cell phones) and financial transactions (e.g. ATM, Internet) in improving administration, communication and access to information.


Shopping on the Internet

  • The purpose of this learning unit is to become acquainted with the rapidly expanding phenomenon of e-Commerce on the Internet.

Activity 1

  • This activity can be done on computers if the facilities are available at the school. Because the information on the Internet regarding e-Commerce may change on a daily basis, the instructions might not necessarily correspond. Keep it in mind!
  • Similar activities can be done by the learners.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
