WAEC Computer Studies 2023 Paper

Concept:Alpha-numeric data is any data that combines alphabetic letters and numeric digits together.Explanation:Check each option for the presence of both letters and numbers.$568$ contains only digits, so it is numeric data.$10.00$ contains digits with a decimal point, so it is numeric data.$\mathrm{SS3}$ contains the letters “SS” and the digit “3”, so it is an alpha-numeric value.“Twenty-five” is written as a word, so it is alphabetic data, not alpha-numeric.Therefore, the only option that mixes alphabets and numerals is $\mathrm{SS3}$.Answer:$\mathrm{SS3}$ (Option C).
