- USB is a full standard, from physical connection all the way up to software stacks (RS-232 only really defines the electrical interface)
- USB is faster
- USB has standard drivers for many different device classes
- USB can provide power for low power devices
- USB has a simple 4 pin connector
- USB allows multiple devices to be connected to a single port on the master via a hub
usb can support the distance upto 5meters only,but rs232 can support upto the distance 30 meters for communication
advantages over what? over 74HC Series? or 74LC Series? or CMOS 4000 series?

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.
logic analyzer advantages
advantage of SSB ic can save power..and also the bandwidth requirements
Yes, you can get a USB to RS232 converter (aka USB to Serial).
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.
Probably the best place to buy an RS232 to USB converter would be Radio Shack followed by Best Buy. A local computer repair shop may also be able to help.
A USB modem plugs into your USB port.A "normal" modem plugs into your RS232 port or your parallel port.
Different data rate speed (for rs232 is lower), usb is more flexible and takes less energy. Different instructions and commands. If you are a programmer then it's easier for to work with usb then with rs232.
Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.

The advantages of a USB SD are that you can store information. The disadvantages of USB SD card reader is that it can be lost easy.
This interface is easy to use and to learn. Some disadvantages would be that it does not have all of the features that you may want.
The advantages of USB oscilloscopes are the ease of use and setup, compatible of 1.1 and 2.0 USB port, and also transfers data rate is extremely faster.
rs232 isfaster than rs449
