What is the difference between rs232 and rs485 port?
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.
What are the Differences between RS232 and RS449?
rs232 isfaster than rs449
What is 232 in RS232 and MAX232?
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.
What is the difference between CAN and I2C?
We can use I2C only for small distance communication not more than 1 meter, but CAN bus can be used for more than this distance that's why in todays world CAN bus is most preferred in Automotive Industry.

Difference between usb modem and normal modem?
A USB modem plugs into your USB port.A "normal" modem plugs into your RS232 port or your parallel port.
What is the difference between i2c and spi?
Major Difference Between SPI and I2C is: SPI is full Duplex (SPI can be full/half duplex, depending on the hardware, 3 or 4 wire) and I2C is half duplex communication....we cannt send and receive data at a time in I2c..but it possible in SPI ....SPI much faster Than I2C....... Main topic to discuss the difference is 1) speed is difference in case of i2c is 100/400kbps in 7 bit mode max 400kbps (But High speed I2C communication protocols allow speeds upto 3.4Mbps!!) in case of spi speed is upto 1mbps (the higher speed of SPI is due to fact that unlike I2C, SPI interfaces to a slave device using a sperate pin called the slave select + no concept of acknowledgements which means increased Band width..) 2)Connection wise: i2c require less pin then spi (SPI 3wire: 3 IOs, SPI 4 wire: 4 IOs, I2C: 2 IOs) as spi require slave select for individual device... 3)it is better to use i2c in case of if u want to connect more device to connect. (slave addressing advantageous over SPI slave select individual pins for individual slaves) 4)bus arbitration is possible in case of i2c... not in case of spi... (SPI does not require it, since only 1 slave is controlled by the master at any given point) 6)noise sensitivity of i2c is high... there is chance to corrupt the r/w bit... then whole data is corrputed... but in case of spi.. chance is very less as whole word is trasmitted... However, I must say that I2C is more reliable, since the protocol supports slave feedback machanism (ACK) to detect whether was received correctly or corrupt. 8) it is easy to implement the spi...while i2c is little bit complex...

What do you use in laptop - rs232 or rs485?
rs232
What does i2c stand for in the terms of power?
In terms of power I2C stands for an "Inter-Integrated Circuit". An I2C is used to connect slow speed computer components to the motherboard or other electronic devices.
How can iget adapter to dell compute to fit rs232 cable?
Could you be more specific? What do you need and RS232 cable for? Old serial device of some kind? Also, what Operating System is on your Dell machine, that will actually make a difference.
