Identify the correct order in which a server process must invoke the function calls accept, bind, listen, and recv according to UNIX socket APL

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

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 __________.

Consider a typical disk that rotates at $$15000$$ rotations per minute $$(RPM)$$ and has a transfer rate of $$50 \times {10^6}\,\,\,bytes/\sec .$$ If the average seek time of the disk is twice the average rotational delay and the controller’s transfer time is $$10$$ times the disk transfer time, the average time (in milliseconds) to read or write a $$512$$-byte sector of the disk is ______________________.
