Give below are two statements: Statement I : CDs and DVDs are described as magnetic storage devices. Statement II : Laser printers are made up of a print head consisting of nozzles that sprays droplets of ink onto the paper to form characters. In the light of the above statements, choose the correct answer from the options given below:
Both Statement I and Statement II are false.
Concept: Storage devices and printers are classified by the technology they use. CDs and DVDs use a laser to read and write data as tiny pits on a reflective surface, so they are optical storage, not magnetic. Printers likewise differ by mechanism: inkjet printers spray droplets of ink, while laser printers use a laser, a charged drum and toner powder fused by heat.
Evaluating the statements:
Statement I: 'CDs and DVDs are described as magnetic storage devices.' This is false. CDs and DVDs are optical storage devices; magnetic storage refers to devices such as hard disks and magnetic tapes.
Statement II: 'Laser printers are made up of a print head consisting of nozzles that spray droplets of ink onto the paper to form characters.' This is false. The description of nozzles spraying ink droplets is that of an inkjet printer, not a laser printer; laser printers form characters using a laser beam, an electrostatically charged drum and toner.
Conclusion: Both statements misdescribe the technology, so both are false.
Why the other choices are wrong: Any option that treats either statement as true is incorrect, because CDs/DVDs are optical (not magnetic) and the ink-nozzle description belongs to inkjet (not laser) printers.
Takeaway: CDs/DVDs are optical storage, and spraying ink droplets is what inkjet (not laser) printers do.
Correct answer: Both Statement I and Statement II are false.
