Which three basic parts are common to all frame types supported by the data link layer?
header trailer Data
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.
Difference between ATM and frame relay?
ATM as well as frame relay are switched WANs. Frame relay protocol was designed to replace X.25 . ATM is advantageous as it is a cell network and a cell network uses the cell as a basic unit of data exchange and are small and fixed size block of information .
A device receives an Ethernet frame and recognizes the MAC address as its own. What does the device do to the message to get to the encapsulated data?
Removes the Ethernet header and trailer
An Ethernet MAC sublayer receives 1510 bytes of data from LLC layer can data be ccencapsulated in one farme?
maximum data size in the Ethernet is 1500 bytes The data must split between two frames first frame must carry the maximum number of bytes 1500 second frame needs to carry only 10 bytes so: Data size for the first frame: 1500 bytes Data size for the second frame: 46 bytes with padding Answer in Arabic حجم البيانات القصوى في Ethernet القياسي هو 1500 بايت. البيانات من 1510 بايت، لذلك، يجب حدوث تقسيم بين إطارين. المعيار يفرض أن الإطار الأول يجب أن تحمل أقصى عدد ممكن من البايت اي (1500). الإطار الثاني بعد ذلك يحتاج فقط لنقل 10 بايت من البيانات؛ ومع ذلك فهو يتطلب حشوة لتصل إلى 46 بايت. وفيما يلي تفصيل يبين: حجم البيانات لالإطار الأول: 1500 بايت. حجم البيانات لالإطار الثاني: 46 بايت مع الحشو.

What is the correct order for PDU encapsulation?
Frame Header - Network Header - Transport Header - Data - Frame Trailer
How much data can a typical frame contain?
1500 bytes
What are the differences between segment packet and frame?
Theoretically Data Link Layer puts packet into frame by adding header and tail to the packet but how is it possible when you take into consideration CCSDS packet definition:"A packet is a block of data with length that can vary between successive packets, ranging from 7 to 65,542 bytes, including the packet header.Packetized data are transmitted via frames, which are fixed-length data blocks. The size of a frame, including frame header and control information, can range up to 2048 bytes."According to this, frame is smaller than packet, so how can you put packet into frame??
What is the purpose of padding in an Ethernet frame?
ensuring that the data portion of the frame totals at least 46 bytes
Which three basic parts are common to all frame types supported by the data link layer?
header trailer Data
How does the data link layer prepare packets for transmission?
It encapsulates with a header and a trailer to create a frame.
What is the maximum size of data that the application layer can pass on to the TCP layer below?
2^16 bytes - size of TCP header
What protocols are in the Ethernet frame?
The ethernet frame carries the IP (Internet Protocol) The Ethernet frame is made up of the following: 7 BYTE PREAMBLE 1 Byte "Start OF Frame" delimiter 6 byte destination address 6 byte source address 2 byte length or type 46 - 1500 bytes variable 802.2 or ethernet header and data 4 byte Frame Check sequence
The data portion of an ethernet frame may contain bytes of information?
46 to 1500
What is added when extra filler data is needed in a packet?
In Computer networking, you have data that is transmitted through packets. In which is what we call an Ethernet frame. That Ethernet frame broken up into several pieces. They are:The PreambleRecipient's MACSender MACTypeData (Your information)Pad (FILLER)FCSThe reason why we have the "Pad" is because your standard minimum for an Ethernet frame size is 64 bytes. However, it doesn't all have to be your actual data. For example, if you were to send data that was not 64 bytes. Your NIC (Network Interface Card) will automatically add extra data which is what we can the "Pad" portion. This adds data so that we are back up to the minimum value of 64 bytes within an Ethernet frame.
What does the data section of a frame contain?
The data section of a frame is also known as the "payload". It consists of the actual data being sent along with the headers of other PDU's in the frame. The size of the data section can vary from less than 50 bytes to 16KB, depending on the network type.
Why 64 bytes minimum in ieee 802.3?
FOR THE 802.3 FRAME CONTAINS Ethernet Header = 18 Bytes [Dst Mac(6) + Src Mac(6) + Length (2) +CRC(4)]Minimum Data Portion = 46 BytesMinimum Ethernet Frame Size = 64 Bytes Frames must be at least 64 bytes long, not including the preamble, so, if the data field is shorter than 46 bytes, it must be compensated by the Padfield. The reason for specifying a minimum length lies with the collision-detect mechanism. In CSMA/CD a station must never be allowed to believe it has transmitted a frame successfully if that frame has, in fact, experienced a collision. In the worst case it takes twice the maximum propagation delay across the network before a station can be sure that a transmission has been successful. If a station sends a really short frame, it may actually finish sending and release the Ether without realising that a collision has occurred. THATS WHY IT IS MINIMUM 64 BYTES
