Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".

What is an updated and digital version of X25 that also relies on packet switching?
Frame relay.
Define the terms packet datagram frame and token?
Data is transmitted on a network in pieces called packets, datagrams, or frames. Specifically, the frame is the header and trailer surrounding the data. The entire header, trailer, and data is called the packet or datagram. A token is a small packet used on Token Ring or FDDI networks. The token is passed from node to node to indicate to the node that data can be sent on the network.
Host a sends a frame with the destination mac address as ffffffffffff what action will the switch take for this frame?
It will send the frame to all hosts except host A.This is a MAC broadcast address. All hosts on that subnet will receive the packet or frame. With the exception of the sending host of course.
The PDU at the Network layer is called?
The PDU at the Network layer is referred to as a packet. A PDU at the Data Link Layer is referred to as a frame.
How many fields are used in a data packet in a J1939 data transaction?
7 per "Electronic Diesel Engine Diagnosis". Start of Frame Arbitration Field Control Field Data Field CRC Field Ack field End of Frame
Do frame encapsulate packet or do packet encapsulate frame?
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".
Do frame encapsulate packet or packete encapsulate frames?
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".
Do frames encapsulate packets?
Frames encapsulate packets. When a packet arrives at the data link layer, the entire thing, header, data, and all, is used as the data field of a frame. The entire packet is put in an envelope (the frame) so to speak (assuming it fits). Citiation: "Computer Networks". By Andrew S. Tanenbaum
Which protocol is used to encapsulate a data packet created of a higher OSI model layer?
LAPD
What does an NIC encapsulate data into for sending that data over a network?
frame
What goes over media -packet or frame-which is more correct?
Packet
Does the data link layer finalize and frame a packet?
yes,data link layer finalize and frame a packet as frame is a series of bits that units a data.........
What is the fuction of the FCS field in an Ethernet frame?
The FCS (Frame Check Sequence) Component of an ethernet frame permits the end recipient to check for, and correct, errors in the packet. It is a checksum that is checked against the packet for data integrity, to put it simply. When the number does not check out properly, the frame is thrown out and a replacement packet is requested.
What is the key responsibility of the switching function within a router?
to encapsulate packets in the correct data link frame type
What does the computer term bits packet frame segment data mean and in what layer they belong?
Telegrams are sent in data packets. Bits packet frame segment data mean data packet and they belongs to Data link layer. Bye.
What is an updated and digital version of X25 that also relies on packet switching?
Frame relay.
Host A has an IP address of 172.16.225.93 a mask of 255.255.248.0 and a default gateway of 172.16.224.1. Host A needs to send a packet to a new host whose IP is 172.16.231.78. What two things occur?
*Host A will get a result of 172.16.224.0 from the AND process. Host A will send on to the media a broadcast frame that contains the packet. *Host A will broadcast an ARP request for the MAC of the host 172.16.231.78. Host A will change the destination IP of the packet to 172.16.224.1 and forward the packet. Host A will encapsulate the packet in a frame with a destination MAC that is the MAC address associated with 172.16.224.1.
