Which field in an IPv4 packet header will typically stay the same during its transmission?

Destination Address (I.P. ) will stay the same during transmission.
But be careful! Only if it is Ip address. However if it is MAC it will change as it travels thru diferent routers with different MAC addresses to get to the destination Ip address (which does not change)!

Firewall is a router that examines the header of every packet of data it receives to determine whether that type of packet is authorized to continue to its destination?
packet-filtering
Which IPv4 header field is responsible for defining the priority of the packet?
differentiated services
What part of the cdv packet contains data that is being sent?
b. Payload that's what the data in a packet is called. The other parts are "header" and "trailer" depending on if they are at the beginning or end of the packet
The address is used to identify the sender and receiver in an ip packet header?
That is called an IP address.
Packet switch and message switch?
packet switching can be considered an improvement over message switching.Similar to message switching,packet switching forwards data on first come first serve basis between nodes and no dedication connection is made (as it is done in circuit switching). But unlike message switching,packet switching puts an upper limit on the maximum size of the packet.If the packet size is greater than the maximum,it is segmented and then transmitted.Each segment has separate header which increases the overhead. But it reduces the average delays.Also in case of packet switching data is not stored for later transmission to a currently busy or inactive terminal.It just takes care of data transmission between nodes
When creating a packet how does the network layer determine the size of the packet?
The Network layer (Layer 3, typically IP) will receive a segment from the Transport layer (Layer 4, typically TCP or UDP), and will add its own header to it to create a packet. The size of the packet will thus always be the size of the segment plus the Network layer header, the same as when the next layer down (the Data Link layer, layer 2, typically Ethernet) encapsulates the packet into a frame for transmission.
Which field in the IP packet header allows checking for data transmission errors?
time to live
What is The header of an IPv4 packet does not include fields required for?
The header of an IP packet does not include fields required for reliable data delivery. There are no acknowledgments of packet delivery. There is no error control for data.
Why is a packet header important?
aqs WD
What information is used at each hop to determine where the packet will be forward to?
ip packet header
What information is used at each hop to determine where the packet will be forwarded next?
ip packet header
What is Packet Corruption in computer networking?
The loss of data packets during transmission.
In the IP Protocol What is the header overhead?
Internet Protocol, or IP, puts a header on every packet that it sounds out. This header is the overhead. All protocols, such as TCP or UDP, will put a header on the packet. The IP header contains information such as source IP address and destination IP address and is used by routers to figure out where to send the packet. ex. you send your friend a 1kb file, but it takes up 1.5kb of bandwidth due to overhead
What is the component of data link?
header, packet(data), and trailer
What in an IP packet header contains information that prevents a packet from continuously circulating around a network?
See time-to-live (TTL) packet
What data can an ip packet contain?
An IP packet can contain data about the format of the internet header and the abstract parameters such as the header checksum. The IP packets also provide an internet time stamp.
