Self Doubt for 3-Dimensional Array
For a C program accessing X [i][j][k] Would the above mean that there are i 2-dimensional arrays of order j*k, from what i know the in Row major all the elements row by row are placed adjacent locations in the memory when one 2-d array is ... 32 + k*4 and could'nt proceed further, how we could deduce the number of 2-d Arrays and the order of those 2-d arrays

FTP and HTTP
FTP and HTTP need underlying layers for Reliability Service and hence TCP is used at the Transport Layer, what protocol will FTP and HTTP use at Network Layer ? Since IP is an unreliable protocol,it does not guarantee the delivery of a datagram to its destination, how application layer data in ensured reliability @ this Network level ?

GATE-CS-2006
Station A uses 32 byte packets to transmit messages to Station B using a sliding window protocol. The round trip delay between A and B is 80 milliseconds and the bottleneck bandwidth on the path between A and B is 128 kbps. What is the optimal window size that A should ... of packets Then optimal Window size is 40 If the RTT=2*Tp then we get Ws = 41, what is the correct approach ?

Rice's Theorem
Example# 3 from Part-1 Rice's Theorem from https://gatecse.in/rices-theorem/ states as follows (3) L(M) is recognized by a TM having even number of states Sol: This is a trivial property. This set equals the set of recursively enumerable languages. ... then? Can someone give me an example for which TYES and TNO cannot be found and let me know if my approach is correct ?

Eigen Values of a skew Symmetric Matrix
The eigen values of a skew-symmetric matrix are (a) Always zero (c) Either zero or pure imaginary (b) always pure imaginary (d) always real if a matrix is skew symmetric then the elements in diagonal should be zero. A= |0 q| |r 0| Now solving for k ... get q=0, r=0, how does this tell us about the eigen values k PS: can't use lambda, so im using k here
