Serial and Parallel Communication
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.
Module Serial Communication
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
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
Purpose of the Serial Ports Parallel Digital Data Expansion Bus Serial Interface In Out Serial Digital Data
Faster RS-232 Serial Ports and Summary Module Faster RS-232 Serial Ports and Summary
Sample USB Devices Keyboards Monitors Digital Cameras Digital Vide Recorders etc.
Advantages of USB Over the RS-232 Port Higher speed Ability to daisy chain different devices Support for hot plug-and-play
Serial Communication Connections Module Serial Communication Connections
Parallel Communication Module Parallel Communication
Definition of Parallel Communication Transmission of information over multiple links between two points Multiple electronic links
Parallel Transmission Multiple links
