PROBLEM WITH BROADCASTING:
There are some issues with the broadcast. For each broadcast frame on the network every computer uses computational sources and places the data into storage, which interrupt the computer. It allows system software to create the decision whether to use or discard the frames.
Another fact is that if a pair of computer need to broadcasting instead of transmitting them directly all other devices waste CPU time while discarding the packet frames.
IDENTIFYING PACKET CONTENTS:
The destination must get some answer about how to interpret frame packet data. For this purpose it may use two kinds which are shown as follows.
EXPLICIT FRAME TYPE:
In this kind the identifying value is added with frame describes kinds of included data.
IMPLICIT FRAME TYPE:
In implicit frame the receiver have to infer from frame data.
