In a more modern setting, 70-293 imagine a piece of equipment in a very dangerous place, like in a steel processing mill that measures the temperature of the rollers or other steel processing equipment. This would also be a form of what we now refer to as a piece of "Data Communication Equipment" that we would also want to be able to control remotely. 70-297 The PC that is used in a control room of the mill would be the Data Terminal Equipment. There are many other similar kinds of devices, and RS-232 connections can be found on all kinds of equipment.
The reason this is called a "straight" connection is because when the cabling is put together, each wire on each end of 70-528 the connection is put to the same pin. This wiring system will be explained further on.
