| | Data Communications Basics |
| | Data representing a computer program, on the other hand, may be reduced only by 15 or 20 percent. | | | 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. | | | Although some precautions must be taken for data exchange within a computer, the biggest problems occur when data is transferred to devices outside the computer's circuitry. |

| | Data Communications |
| | Data Communications is the transfer of data or information between a source and a receiver. | | | The actual generation of the information is not part of data communications nor is the resulting action of the information at the receiver. | | | Even though the computers can have different disk operating systems, languages, cabling and locations, they still can communicate to one another and share resources. |

| | data communications |
| | In popular usage, it is said that data communications make it possible for one computer to “talk” with another. | | | Because many computers can be on the network at any given time, techniques such as time-division multiplexing are used; each computer is assigned a short time slot during which it can use the full bandwidth of the network. | | | Local-area and wide-area networks link computers together so that they can transfer and share data. |
