This method uses a field in the header to specify the number of characters in the frame. When the data link layer at the destination sees the character count,it knows how many characters follow, and hence where the end of the frame is. The disadvantage is that if the count is garbled by a transmission error, the destination will lose synchronization and will be unable to locate the start of the next frame. So, this method is rarely used.
its when the sending device keeps a copy of the last frame transmitted until it receives ACK. Keeping a copy allows the sender to retransmit lost/damaged frames until received correctly. If the receiver detects error in frame, it discards it and sends no ACK
When you want to group several controls together - name and address, for example - you use a Frame. The frame backcolor can be the same as the form's and only the frame borders will be obvious, or it can be a different color and stand out.You create the frame before the controls. When you create controls in a frame, they are tied to the frame and move with it. The frame caption is the text that appears at the top of the frame - you use it to define the group.

Same as that of the applet we need to run this frame...........
Each Ethernet frame contains a trailer with a cyclic redundancy check (CRC) of the frame contents. After reception of a frame, the receiving node creates a CRC from the bits in the frame to compare to the CRC value in the frame trailer. If these two CRC calculations match, the frame can be trusted as being received without error. The trusted frame will then be processed. A frame received with bad, nonmatching CRC's will be discarded.
In an Ethernet frame, FCS stands for "Frame Check Sequence". It is a four-octet field used to verify that the frame was received without loss or error. The method used for verification is known as a Cyclic Redundancy Check (CRC).
The information found in the Ethernet frame trailer would be the error checking code.

The purpose of the FCS field is to transmit the extra checksum characters added to a frame in "xyz" protocol for error detection. The most popular algorithm I've used is the CRC (cyclic redundancy check) employed in things like ethernet or PPP on a routed network. Keep in mind that ethernet defines that the errored frame should be discarded, but ethernet takes no action to cause the frame to be retransmitted. Typically most tech's see it as unnecessary overhead and opt to rely on CSMA\CD or CSMA\CA if the route is not deemed to carry time sensitive data. Hope that clears things up a bit.
