Communication between a computer and a keyboard primarily involves one-way transmission from the keyboard to the computer, which is Simplex communication. D 17. To find the result of binary multiplication 1010_2 × 1100_2: First, convert to decimal: 1010_2 = 1 · 2^3 + 0 · 2^2 + 1 · 2^1 + 0 · 2^0 = 8 + 0 + 2 + 0 = 10_10 1100_2 = 1 · 2^3 + 1 · 2^2 + 0 · 2^1 + 0 · 2^0 = 8 + 4 + 0 + 0 = 12_10 Multiply the decimal values: 10_10 × 12_10 = 120_10 Convert 120_10 back to binary: 120 ÷ 2 = 60 remainder 0 60 ÷ 2 = 30 remainder 0 30 ÷ 2 = 15 remainder 0 15 ÷ 2 = 7 remainder 1 7 ÷ 2 = 3 remainder 1 3 ÷ 2 = 1 remainder 1 1 ÷ 2 = 0 remainder 1 Reading the remainders from bottom up gives 1111000_2. Comparing this with the given options: A. 0001111_2 = 15_10 B. 111000_2 = 112_10 C. 0011111_2 = 31_10 D. 111100_2 = 60_10 None of the options exactly match 1111000_2. However, if we assume a typo in the question and the multiplication was intended to be 1010_2 × 110_2: 1010_2 = 10_10 110_2 = 1 · 2^2 + 1 · 2^1 + 0 · 2^0 = 4 + 2 + 0 = 6_10 10_10 × 6_10 = 60_10 60_10 = 111100_2. This matches option D. Assuming the typo, the answer is D. 18. The circuit shows an OR gate with inputs A and B, followed
