GATE CSE 2005 | Question: 70
Consider a disk drive with the following specifications: $16$ surfaces, $512$ tracks/surface, $512$ sectors/track, $1$ KB/sector, rotation speed $3000$ rpm. The disk is operated in cycle stealing mode whereby whenever one $4$ byte word is ready it is sent ... $40$ nsec. The maximum percentage of time that the CPU gets blocked during DMA operation is: $10$ $25$ $40$ $50$

GATE CSE 2006 | Question: 40
Consider numbers represented in 4-bit Gray code. Let $ h_{3}h_{2}h_{1}h_{0}$ be the Gray code representation of a number $n$ and let $ g_{3}g_{2}g_{1}g_{0}$ be the Gray code of $ (n+1)(modulo 16)$ ... $ g_{3}(h_{3}h_{2}h_{1}h_{0})=\sum (0,1,6,7,10,11,12,13) $

Let $P_{1},P_{2},\ldots,P_{n}$ be $n$ points in the $xy-$plane such that no three of them are collinear. For every pair of points $P_{i}$ and $P_{j}$, let $L_{ij}$ be the line passing through them. Let $L_{ab}$ be the line ... or the smallest $y$-coordinate among all the points The difference between $x$-coordinates $P_{a}$ and $P_{b}$ is minimum None of the above

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 $80$ $ms$ and the bottleneck bandwidth on the path between $A$ and $B$ is $128$ $kbps$. What is the optimal window size that $A$ should use? $20$ $40$ $160$ $320$
