| | Add-on high speed data communications cards with 16550A (or equivalent) UARTS are also available at your local computer store at prices ranging from $20 to $75 depending upon the number of ports and other features. | | | It is important to understand the difference between "line speed" (the speed with which your modem talks to the other modem), and Data Terminal Equipment or "DTE speed" (the speed with which your PC talks to the modem). | | | Communications software that utilises INT14 i/o can also cause comm overruns. |

| | The North American Data Communications Museum (NADCOMM) is committed to the project of collecting, displaying, and operating the equipment which has powered the communications revolutions of the twentieth century, from telegraphy to digital telephony. | | | "Data Communications Technology from Telegraph to Digital Transmission." The main location is in San Diego, California, but properties in four other cities house parts of their collection. | | | NADCOMM's goal is to counter the present state of communications history, marked by the quick and successive obsolescence of "last year's models," by maintaining a working collection of functional equipment tracing the stages through which teletechnology has passed. |

| | The Development of Communication Networks |
| | It has developed from something known only to big organizations where heavy data processing (for that time) on big computers was their main task, to a widespread tool, used in any office and many houses, to connect smaller and stronger computers to many types of communication networks. | | | Communication extensions are found in any computer and communication equipment and software are more widely distributed throughout a population, enabling easy information exchange between stations on different sides of a room or on different sides of the world. | | | Future Communication Networks are planned to meet future requirements: transferring voice data and video, which means more and more bandwidth for the communication users. |
