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
How much data can be stored in a system that has a capacity of 232 bytes?
A system with a capacity of 232 bytes can store 4,294,967,296 bytes of data.
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
What is the maximum permittable size in bits for an IPv4 packet?
The maximum permissible size for an IPv4 packet is 65,535 bytes, which includes both the header and the data payload. Since the maximum size of the header is 60 bytes, this allows for a maximum data payload of 65,475 bytes. However, in practical use, the Maximum Transmission Unit (MTU) often limits the size of packets on networks, typically to 1,500 bytes for Ethernet.
Which three basic parts are common to all frame types supported by the data link layer?
header trailer Data
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
How does the data link layer prepare packets for transmission?
It encapsulates with a header and a trailer to create a frame.
SONET frame format consists of -how many bytes in overhead and how many bytes for payload?
The SONET (Synchronous Optical Network) frame format consists of 9 bytes of overhead and a payload of 243 bytes, making a total of 252 bytes per frame. The overhead is used for management, control, and error-checking functions, while the payload carries the actual user data. This structure allows SONET to efficiently manage high-speed data transfer across optical networks.
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.
