a bit synchronizer is a ckt which made at the receiver end at that time when a bit interval end and next starts.
Which of the OSI layers handle the following. 1.dividing the transmitted bit stream into frames? Data link layer Which of the OSI layers handle the following: 2.dividing the application data into segments? Transport layer the PDU (Packet Data unit) for layers is as the following - Application, Presentation, and Session layers ==> uses Data - Transport layer ==> uses Segment - Network layer ==> uses Packets - Data link layer ==> uses Frames - Physical layer ==> uses Bits. ....

synchronization between the multiplexer and demultiplexer is a major issue in data transmission. if the multiplexer and demultiplexer are out of synchronization a bit belonging to one channel may be received by the wrong channel. for dis reason , one or more synchronization bits are usually added to the beginning of each frame. these bits, called framing bit , follow a pattern, frame to frame, that allow the demultiplexer to syncronize with the incoming steam so that it can separate the time slots accurately. in most cases, this syncronization information consists of one bit
- synchronization in which the decision instants is brought into alignmentwith the received bit,i.e, the basic signaling element.- it is used to generate a clock signal at the proper sampling instants. - it consists of non linear element followed by phase locked loop ( PLL ).
It handles Error Recovery, flow control (synchronization) and seqencing (which terminals are send and which are receiving).It is Considered the "Media access control layer"and is where MAC Addressing is defined.Answer:Data Link Layer
a thunking layer
Bit stuffing is the insertion of non information bits into the data bits.In high level data link control protocol(HDLC),it provides a means of synchronization.
Session layer.The session layer provides the mechanism for opening, closing and managing a session between end-user application processes, i.e., a semi-permanent dialogue.
