Operating System
In a computer system, three files of size 11052 B, 4992 B and 5172 B need to be stored. For storing these files on disk, we can use either 100 B disk block or 200 B disk block. For each block used to store a file, 2 bytes of book ... data from a file, but not both. What is the total space required for storing the files using 100 B and 200 B disk blocks respectively___________

Doubt regarding the concept of pipelining
GATE2015-3_36 Time required to reach destination of first packet goes the normal way (.ie including time for all transmission, switch delay, propagation delay and all that ) and after the first packet is received, remaining packets would require only transmission time . Is it the right concept that I am having regarding pipelining in Computer network.
