Assume that the bandwidth for a TCP connection is 1048560 bits/sec. Let $\alpha$ be the value of RTT in milliseconds(rounded off to the nearest integer) after which the TCP window scale option is needed. Let $\beta$ be the maximum possible window size the window scale option. Then the values of $\alpha$ and $\beta$ are
A
63 milliseconds, $65535 \times {2^{14}}$
B
63 milliseconds, $65535 \times {2^{16}}$
C
500 milliseconds, $65535 \times {2^{14}}$
D
63 milliseconds, $65535 \times {2^{16}}$

### GATE CSE 2015 Set 2

Assume that for a certain processor, a read request takes $50$ nanoseconds on a cache miss and $5$ nanoseconds on a cache hit. Suppose while running a program, it was observed that $80\%$ of the processor's read requests result in a cache hit. The average read access time in nanoseconds is __________.
