Ipod Nano

Ipod Nano
The software bundled with the first generation iPod was Macintosh-only, so Windows users had to use third-party software like ephPod or XPlay to manage their music. When Apple introduced the second generation of iPods in July 2002, they sold two versions, one that included iTunes for Macintosh users and another that included Musicmatch Jukebox for Windows users.[43] In October 2003, Apple released the Windows version of iTunes,[44] and started selling iPods that included both Macintosh and Windows versions of iTunes so that they could be used with either platform. Current iPods no longer ship with iTunes, which must be downloaded from Apple's website.
In December 2002, Apple unveiled its first limited edition iPods, with either Madonna’s, Tony Hawk’s, or Beck’s signature or No Doubt's band logo engraved on the back for an extra US$50.[45] On 26 October 2004, Apple introduced a special edition of its fourth generation monochrome iPod, designed in the color scheme of the album How to Dismantle an Atomic Bomb by Irish rock band U2. It had a black case with a red click wheel and the back had the engraved signatures of U2's band members. This iPod was updated alongside the iPod Photo and fifth generation iPod.
On 13 October 2006, Apple released a special edition 4 GB red iPod Nano as part of the Product Red campaign. An 8 GB version was released three weeks later and both of them sold for the same price as the standard models. US$10 from each sale is donated to The Global Fund to Fight AIDS, Tuberculosis & Malaria. On 5 September 2007, Apple also added a Product Red iPod Shuffle model. They did not disclose how much will be donated to charity from this model. Apple also released Special Edition Harry Potter iPods to accompany the iPod Photo. These were engraved with the Hogwarts Crest on the back and were only available to purchasers of the Harry Potter audiobooks. They were updated when the fifth generation iPods were released, but were only available for a limited time.

Network and Internet

Network and Internet
Computers have been used to coordinate information between multiple locations since the 1950s. The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems like Sabre.
In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology. This effort was funded by ARPA (now DARPA), and the computer network that it produced was called the ARPANET. The technologies that made the Arpanet possible spread and evolved. In time, the network spread beyond academic and military institutions and became known as the Internet. The emergence of networking involved a redefinition of the nature and boundaries of the computer. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an individual computer. Initially these facilities were available primarily to people working in high-tech environments, but in the 1990s the spread of applications like e-mail and the World Wide Web, combined with the development of cheap, fast networking technologies like Ethernet and ADSL saw computer networking become almost ubiquitous. In fact, the number of computers that are networked is growing phenomenally. A very large proportion of personal computers regularly connect to the Internet to communicate and receive information. "Wireless" networking, often utilizing mobile phone networks, has meant networking is becoming increasingly ubiquitous even in mobile computing environments.
