Question

think of a way that a packet can be damaged and still have the same checksum as the undamaged version (there are several possibilities. imagine that two or more bytes are altered at the same time). give one example for this scenario.

Answer 1

A packet can be damaged and still have the same checksum as the undamaged version if two or more bytes are altered at the same time.

Step-by-step explanation:

In computer networks, a checksum is used to detect errors in transmitted packets. However, it is possible for a packet to be damaged and still have the same checksum as the undamaged version. One example is when two or more bytes are altered at the same time. Let's say we have a packet with the bytes '0101'. If two of these bytes are changed to '1111', we would still have the same checksum because the number of '1's and '0's in the packet remains the same.
