3. Serial and Parallel Communication

4. Chapter Objectives Explain serial communication
Standards, ports, resources etc.
Show a few examples of serial communication connections used in practice
Describe the features of parallel communication
Standards, use etc.

5. Module
Serial Communication

6. Serial Communication Implementation
Popular implementation found in older and some newer computers is known as the RS-232 serial connection found in microcomputers
Newer type of serial connections
Universal Serial Bus (USB)
IEEE 1394 serial connection that is also known as the FireWire connection

7. RS-232C Serial Standard The most popular standard
Conforming serial ports are found in the following
Micro
Minis and mainframes
Sometimes these ports are also known as the asynchronous ports or asnch ports in short
It is also possible to conduct synchronous transmission through these ports as well

8. Purpose of the Serial Ports
Parallel
Digital
Data
Expansion
Bus
Serial Interface In
Out
Serial Digital Data
