Detailed Explanation:

RAID 5 provides block-level striping with single distributed parity.

Detailed Explanation:

An XNOR gate produces output 1 when both inputs are identical.

Detailed Explanation:

0xAA in binary: 10101010.

0x55 in binary: 01010101.

XORing 0xAA ⊕ 0x55 = 11111111.

Detailed Explanation:

$TLB Hit Time = t_{TLB} + t_{mem} = 20 + 100 = 120 ns.$

$TLB Miss Time (4-level paging = 4 page table accesses + 1 data access) = t_{TLB} + 5 \times t_{mem} = 20 + 500 = 520 ns.$

Detailed Explanation:

Total time = 10 hours = 10 $\times 3600 seconds = 36,000 seconds$.

Total transmitted bits = 2.048 $\times 10^6 bps \times 36,000$$s = 73,728,000,000 bits = 7.3728 \times 10^10 bits$.
