ISRO Scientist/Engineer Question Paper Computer Science 2013

Two eight bit bytes 1100 0011 and 0100 1100 are added. What are the values of the overflow, carry anf zero flag respectively, if the arithmetic unit of the CPU uses 2s complement form ?

How many check bits are requires for 16 bit data word to detect 2 bit errors and single bit correction using hamming code ?

What is the maximum number of characters(7 bits + parity) that can be transmitted in a second requires 1 start bit and 1 stop bit

IEEE 1394 is related to

What will be the cipher text produced by the following cipher function for the plain text ISRO with key k=7 [Consider A=0, B=1,…….Z=25]
Ck(M) = (kM + 13) mod 26
