For example, the ancient Chinese observed that certain rocks (lodestone) were attracted to one another by some invisible force. This effect was later called magnetism, and was first rigorously studied in the 17th century. A little earlier than the Chinese, the ancient Greeks knew of other objects such as amber, that when rubbed with fur would cause a similar invisible attraction between the two. This was also first studied rigorously in the 17th century, and came to be called electricity. Thus, physics had come to understand two observations of nature in terms of some root cause (electricity and magnetism). However, further work in the 19th century revealed that these two forces were just two different aspects of one force – electromagnetism. This process of "unifying" forces continues today, and electromagnetism and the weak nuclear force are now considered to be two aspects of the electroweak interaction.

No doubt, information is the highway to greatness in life. In a bide to obtain such information one is forced to get it whenever it appears online. One is please and satisfy with the rate of such information transfer if it is very fast. But the reverse is case when the data transfer ( i.e. bits or bytes per second ) is very slow. One is bound to waste time to be used for other demanding issues on a slow data transfer. But you can get out of this mess and speed up the rate of data transfer of your computer by applying the tips in this article.
Change or upgrade your connection. Your internet service provider render service according to your subscription. There is a limit speed associated with each connection. So, go for subscription that meet up with your need. If you are using dial-up connection, make use of Broadband connection for faster speed output. The broadband has Direct Service Line ( DSL) or a cable connection to be chosen for maximum performance.
