Its not, it just happens to be convenient. Other standards for UART communication include RS-422, RS-423, RS-481, and various others.

RS232 is a communications protocol for electronic devices to exchange information
RS-232 serial ports are far slower than USB ports. With very few exceptions, devices that use USB ports would be impractical to use on a serial port.

Whwn an IC is connected to a PC, then the voltage levels of these two should be synchronized. For this purpose, the TTL voltage level is converted to RS 232 level. RS 232 is the interface between a PC and an IC.
Depends what you mean by a serial cable - Fibre, Ethernet, RS232, RS485, RS422, USB, HDMI, SMPTE292 are all examples of serial communications media. RS232 max length 50 ft Ethernet max length 100 m
Difference between Rs232 and RS485 is Only Distance RS232 is not for long or far distance .. but RS485 can be use for LONGEST distance ..RS232 is single ended communication where as RS485 is Differential communication.Max.no of receivers in RS232 is only ONE, whereas in RS485 is 32.Max.no of transmitters in RS232 is only ONE whereas in RS485 is 32.IN RS232 there is no pin to change from transmitter mode receiver mode. But, In RS485 have DE pin to set transmitter mode and RI to set receiver mode.
