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 cro and powerscope?
There is no difference between the two products.
the difference between activity and experiment is ...experiment is do
what is the difference between PCR simplex and multiplex
There is no meaningful difference between those two terms.

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...

I2C (Inter-Integrated Circuit) is a serial communication protocol that uses two wire lines for communication, allowing multiple devices to be connected in a network. RS232 (Recommended Standard 232) is a serial communication standard that uses a single wire for data transfer and is commonly used for connecting devices like modems, printers, and GPS receivers. Additionally, RS232 uses voltage levels for signaling while I2C uses open-drain signals.
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.

HP is a company that makes and market particular hardware / software for speciallist application. An example is the 12C calculator which is capable of using a GPIB standard chip to send a signal through a RS485 cable to a computer
Two roles of nodes in I2C communication are: master and slave.Master node - node that generates the clock and initiates communication with slavesSlave node - node that receives the clock and responds when addressed by the master
difference between as on and as at
Yes. It is operating in synchronous with the clock. Two wire communication. SDA, SCL and GND pins.
