Official scope and exam focus

For CET Senior Secondary Level 2026, Computer Knowledge is not an open-ended history-of-computers chapter. The official scope includes characteristics and applications of computers; computer organization including memory, file system, input devices and output devices; and MS Office knowledge of MS Word, MS Excel or spreadsheet, and MS PowerPoint. This means this topic should stay close to practical school-and-office computing, not deep engineering, programming, computer generations, supercomputers, artificial intelligence, or number-system conversions unless another topic explicitly asks for them.

The exam-ready approach is to connect each term with a use case. Characteristics answer why computers are useful. Applications answer where computers are used. Organization answers how major parts work together. MS Office answers which office tool fits a document, table, calculation, chart or presentation task. Questions are likely to be direct matching, definition, example and function-based items, so small distinctions matter: RAM is not storage, a printer is not an input device, and Excel is not mainly for slide shows.
