RS232C is a standard that specifies different aspects of the serial interface, including voltage levels. Microprocessors don't give those voltages (and don't require the corresponding supply voltages either), so yes you typically need a level converter (MAX232 is a popular possibility).

You should learn to use Google, and look for:
- the RS232C specifications;
- the datasheets for the components you intend to use;
- some relevant articles (CodeProject has at least 3 articles mentioning MAX232).

Warning: if you make a mistake, you're likely to damage one or more of the parts involved. So it is very wise to do first experiments with a part that is easily replaced, such as your USB-to-RS232C cable or a plug-in card in a desktop computer, and NOT with a serial port on the motherboard.
