We can explore some of the widely used commercial and noncommercial Unix networks and the services they offer. Telecommunications system like the Internet is one of the most useful and rapidly growing areas of computing. Vast amounts of digital data pass each day through copper wire, optical fibers, and more over air waves via cellular modems. And this data exchange is not limited to our home cities or stats; today we can communicate with computers that are sitting on the desks of people literally anywhere in the world at any time of the day. Analog voice data new takes second place compared to the volume of digital data being sent and received internationally. The applications are legion. Transactions on the Tokyo stock exchange are available within seconds on the Wall Street analysis’s disk drive. Clusters of corporate PCs interact with mainframes, Local Area Networks, and Wide Area Networks. Weather and military satellites gather and transmit billions of bits each day to dedicated supercomputers.
Transmission speeds are also increasing from year to year. 56k bps modems are now available at prices that would have bought a now-laughable 2,400 bps device just a few years ago. And for those of you who are really hungry for speed, today you can get digital modems and cable modems that, when conditions are right; can attain transfer speeds approaching 100MB. That’s 100 million bits per second. The software to support these advances has also escalated in size and sophistication. New protocols emerge regularly to improve accuracy, handle the connectivity jungle better, and simplify the user interface.
In the modern context, telecommunications and networking includes not only exchanging mail and files, but being able to access resources at a remote computer, for example, executing commands on a far distant Unix system. Communication, media, telecommunication, televisions, operating systems, hardwares are daily updated with new technology. Even health and medicine science also updated with new research and development.
Therefore, technology is expanding everyday and you need to get update from new technology of every aspect, especially your interesting area like business or stock exchange. Internet is the best option to achieve this goal and online technology news or latest IT news is important resource to stay updated on every technologies. Day by day solid changes are being developed in search engine optimization by search engines. Google introduced Panda for duplication and spam content research. Link building services are effective using premium web directory or not. These all news is daily updated in latest IT news.
