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, $$65535 \times {2^{14}}$$

Consider a processor with byte-addressable memory. Assume that all registers, including Program Counter $$(PC)$$ and Program Status Word $$(PSW),$$ are of size $$2$$ bytes. A stack in the main memory is implemented from memory location $${\left( {0100} \right)_{16}}$$ and it grows upward. The stack pointer $$(SP)$$ points to the top element of the stack. The current value of $$SP$$ is $${\left( {016E} \right)_{16}}$$. The CALL instruction is of two words, the first word is the op-code and the second word is the starting address of the subroutine (one word $$= 2$$ bytes). The CALL instruction is implemented as follows:

$$ \bullet \,\,\,\,\,\,\,\,$$ Store the current value of $$PC$$ in the stack
$$ \bullet \,\,\,\,\,\,\,\,$$ Store the value of $$PSW$$ register in the stack
$$ \bullet \,\,\,\,\,\,\,\,$$ Load the starting address of the subroutine in $$PC$$

The content of $$PC$$ just before the fetch of a CALL instruction is $$\left( {5FA0} \right){\,_{16}}.$$ After execution of the CALL instruction, the value of the stack pointer is

A
$$\left( {016A} \right){\,_{16}}$$
B
$$\left( {016C} \right){\,_{16}}$$
C
$$\left( {0170} \right){\,_{16}}$$
D
$$\left( {0172} \right){\,_{16}}$$
