WAEC Computer Studies 2017 Paper

Concept:The ASCII code for a word is not a single code; it is the binary ASCII codes of its letters placed one after another in the same order. So the code for NOT is the combined binary codes of N, O, and T.Explanation:From the standard ASCII table, the decimal values of the uppercase letters are: N = 78, O = 79, and T = 84.Convert each decimal value into binary.$78_{10} = 1001110_2$, so N is represented by $1001110$.$79_{10} = 1001111_2$, so O is represented by $1001111$.$84_{10} = 1010100_2$, so T is represented by $1010100$.Join these binary codes in the order N, O, T.$1001110\;1001111\;1010100$ becomes $100111010011111010100$.This binary string matches option B.Answer:Option B: $100111010011111010100$
