What is Data Communications? Next Topic | TOC The distance over which data moves within a computer may vary from a few thousandths of an inch‚ as is the case within a single IC chip‚ to as much as several feet along the backplane of the main circuit board. Over such small distances‚ digital data may be transmitted as direct‚ two-level electrical signals over simple copper conductors. Except for the fastest computers‚ circuit designers are not very concerned about the shape of the conductor or

study the interaction of small particles which gives us a better understanding of the world. The data which we have on how electrons and atoms interact is gathered mostly on observations alone. For example‚ the properties of hydrogen atoms can distinguish between the different tissues and muscles within the human body‚ this is because the human body consists of 63% of hydrogen atoms and we learn all this data through the understanding of atomic particles. We can discover several ideas‚ if we continue
