In a PPP (Point-to-Point Protocol) frame, the Address field typically contains a single byte value set to either 0xFF or 0x00. When set to 0xFF, it indicates a broadcast address, while 0x00 denotes that the address field is unused in the context of PPP, as PPP is designed for point-to-point links where addressing is not necessary. Therefore, the Address field is effectively ignored during the operation of PPP.

Source MAC-address
The source MAC address within a frame is used by the switch to associate a port with that MAC address. Frames are directed by the switch from one port to another based on the destination MAC address within the frame.

Yes, bit stuffing is needed for the control field in HDLC frames, similar to the address and Frame Check Sequence (FCS) fields. Bit stuffing is used to prevent the occurrence of specific bit patterns, such as the frame delimiter (0x7E), within the data fields, including the control field. By inserting a '0' after a sequence of five consecutive '1's, bit stuffing ensures that the frame remains distinguishable and can be correctly framed during transmission and reception.
Destination address is used to identify the recipient. Thus, a switch can send the frame out the correct port, and the receiving computer can confirm that the frame is for that computer and not for any other computer.Source address allows the receiving computer to know where to send the reply. It also helps a switch learn MAC addresses (learn which MAC addresses are connected to which switch ports).Destination address is used to identify the recipient.

Yes, broadcasts can occur at the Layer 2 level in a network using Ethernet. The MAC address used for broadcast is FF:FF:FF:FF:FF:FF, which signifies that the frame should be sent to all devices on the local network segment. When a device sends a frame with this MAC address, all devices within the same broadcast domain will receive and process the frame.
post indexing First, the contents of the address field are used to access a memory location containing a direct address. This address is then indexed by the register value. pre-indexing An address is calculated as with simple indexing. In this case, however, the calculated address contains not the operand, but the address of the operand.
