Discussion
Which of the following options best describes the truthfulness of the given statements with reference to hardware and software of a computer?
(i) The grid of circuits underneath the keys of a computer keyboard is called as Key matrix.
(ii) An example of software is Windows 11, Adobe Photoshop, and Google Chrome.
Answer: A
Both statements are true. Under a keyboard there is a grid of circuit traces in rows and columns, the key matrix. Pressing a key joins one row line to one column line, and the controller scans the grid to find which key was pressed. The second statement is also correct: Windows 11 is an operating system, Adobe Photoshop is an application program and Google Chrome is a browser, and all three are software rather than hardware. So the options that call either statement false are rejected.
