How does computer understand the following text? (hint: 7 bit ASCII code).
(i)
HOTS
Answer
HOTS: H(72) = 1001000, O(79) = 1001111, T(84) = 1010100, S(83) = 1010011
(ii)
Main
Answer
Main: M(77) = 1001101, a(97) = 1100001, i(105) = 1101001, n(110) = 1101110
(iii)
CaSe
Answer
CaSe: C(67) = 1000011, a(97) = 1100001, S(83) = 1010011, e(101) = 1100101
Explanation
The textbook explains that computers understand only binary language (0s and 1s). When a key is pressed, it is mapped to a unique ASCII code (decimal value), which is then converted to its 7-bit binary equivalent. For example, 'A' maps to decimal 65, which converts to binary 1000001. Following this methodology, each character in the given words is converted to its ASCII decimal value and then to 7-bit binary code.
