What else can I help you with?
What is found on a datalink layer header?
The data link layer header contains the destination and source of information of the original frame and device sending information. You will also find that it contains the information of the device to receive it.
In which of the following would be found in a data link layer header?
The data link layer header contains the source's physical address. It refers the address that is found in the Network Interface Card.
Which OSI layer is responsible for adding a header that includes routing information?
The routing process occurs in the 3rd OSI layer (network layer) routing protocols use network address (IP address in TCP/IP) to chose the correct path to the destination. ps: You can also have routing protocols on other layers sometimes (application layer in p2p routing) but this is something completely different.
What can be identified by the network layer header?
destination host address
Which OSI layer header contains the address of a destination host that is on another?
Network Layer
Why header and trailer is present in network layers?
HEADERS: It is a part of an information structure that precedes and identifies the information that follows,such as block of bytes in communication.TRAILERS:It is an information typically occupying several bytes ,at the tail end of a block of transmitted data which may contain a checksum or other error-checking data useful for confirming the accuracy and status of transmission.
What protocols at other layers of the OSI model does ping use?
Layer 3 of the OSI model. An ICMP header follows the IP header of the IP packet.
Which term refers to stripping header information as a PDU is passed from one layer to a higher layer?
The term that refers to stripping header information as a Protocol Data Unit (PDU) is passed from one layer to a higher layer is "decapsulation." During this process, the headers added by the lower layers are removed, allowing the data to be passed up to the appropriate layer for processing. This is a fundamental aspect of the OSI model and network communication.
What information is added during encapsulation at the OSI layer 3 level?
At the OSI Layer 3, which is the Network layer, encapsulation involves adding a header to the data packet that includes crucial information for routing. This header contains the source and destination IP addresses, which facilitate the proper delivery of packets across different networks. Additionally, it may include other information such as the Time to Live (TTL) and protocol type, aiding in the management of the packet's journey through the network.
What can be indentified by examining the network layer header?
IP Source and IP Destination n
What can be identifies by examining the network layer header?
The source and destination IP address can be identified.
What header information does a router change?
the Layer 2 source and destination address
