2.2 Method of Data Transmission

In serial transmission, how is data transmitted?

• • Multiple bits are transmitted simultaneously

• • One bit is transmitted at a time

• • Data is transmitted using multiple channels

• • Data is compressed before transmission

Which type of transmission is generally faster for short distances?

• • Serial transmission

• • Parallel transmission

• • Optical transmission

• Wireless transmission

Which transmission method is more prone to crosstalk and signal degradation over long distances?
