Its like a two lane bridge on a two-lane highway. Have you ever watched these television talk shows where the host has a number of people on the show, and they all try to talk at once. Well, that's full duplex! Of course, in the world of data communications, full duplex allows both way communication simultaneously. An example can be a consumer which uses a cable connection to not only receive TV channels, but also the same cable to support their phone and Internet surfing. All these activities can occur simultaneously.
In response frames (a reply to a primary station), the address specifies the secondary station sending the response. • Control Field This field holds commands and responses. Examples are sequence numbers (frames are numbered to ensure delivery), and poll (you must reply) and final (this is the last frame) bits. • Information Field This field contains the data. It can contain any sequence of bits. It normal practice it is a multiple of 8 bits. • Frame Check Sequence Field This field contains a 32 bit Cyclic-Redundancy Check (CRC) which covers the A, C and I fields.
In addition, notice that the signal that is sent does not contain any information that can be used to validate if it was received without modification. This means that this method does not contain error detection information, and is susceptible to errors. In addition, for every character that is sent, an additional two bits is also sent. Consider the sending of a text document which contains 1000 characters. Each character is eight bits, thus the total number of bits sent are 10000 (8 bits per character plus a start and stop bit for Copyright ©Genetic Computer School, 1998 Page 41 each character).
