The 232 doesn't stand or come from anywhere. It's just a reference number. RS-232 = Recommended Standard 232
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
Because R2D2 was already taken!
Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.
Through RS232 interface one can connect to service menu and diagnose/configure the device, same applies to service IR codes. I have come across this in televisions.
Also known as a serial cable; typically with 9 or 25 pin D-sub connectors.
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....

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.
Serial port, this one, (http://en.wikipedia.org/wiki/Image:RS-232.jpeg) it is usually coloured green on modern computers.

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.
The input to the max232 ic will be of Transistor Transistor Logic (TTL) and its voltage range will be of 5 volt. The output of the max 232 ic will be of Recomended Standard 232 Logic (RS232 logic) and its voltage range will be of 12 volt. The max 232 ic which is operating on 5 volt supply has to step up the 5 volt input to 12 volt. Hence a capacitor is used for pumping the voltage and called as pumping capacitor.
rs232 isfaster than rs449
Yes, you can get a USB to RS232 converter (aka USB to Serial).
'RS-232' (Recommended Standard 232) is a Standard American format for serial data transmission by cable, such as from computer terminal to modem. RS-232 transmission utilizes a distinctive 25-pin connector, but under most circumstances only a few of the 25 conductors are used. RS-232 was adopted as a standard for serial binary data signals connecting between a DTE (Data terminal equipment) and a DCE (Data Circuit-terminating Equipment). It is commonly used in computer serial ports. RS-232 is similar to the ITU-T standard 'V.24'. The International Telecommunications Union (ITU), which is closely associated with the United Nations (UN), issues various standards for telecommunication systems and equipment for use in all countries which support the UN and ITU.
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.
