Virtual Gate Test Series: Computer Networks - Sequence Number
Consider bandwidth of line is $100$ Mbps and the sequence number of the field consists $32$ bits on a TCP machine. How much time it will take to cover all possible sequence numbers? ________________ sec (integer value only). Mine was $ 343.59$, so $344$ but my answer is wrong.

Virtual Gate Test Series: Computer Networks - Subnet Mask
For class $B$ network, all even bit positions are selected for subnet mask bits. What is the possible subnet mask? $(A) 255.25.170.170$ $(B) 255.255.85.85$ $(C) 255.255.255.240$ $(D)$ None In this question, my doubt is how we can assign subnet mask like this can we? Subnet bits should be taken in continuation from host bits right?
