SSC IMD SA 2017 – Question 109

Which of the following statements is true?

• Magnetic tape can act as an input medium.
• Magnetic tape can act as an output medium.
• Magnetic tape can act as a secondary storage medium.
• All options are correct

Detailed Explanation:

The correct answer is d) All options are correct (सभी विकल्प सही हैं).

Characteristics of Magnetic Tape:

• Secondary Storage Media: Magnetic tape is a durable, non-volatile, sequential-access magnetic recording medium widely used as secondary/tertiary storage for large-scale enterprise data backups and cold archives due to its low cost per gigabyte and long archival life.
• Input Media: Pre-recorded data stored on magnetic tape can be read by a magnetic tape drive and loaded into the computer’s main memory for processing, functioning as an input medium.
• Output Media: The central processing unit (CPU) can direct computation results, databases, and logs to be written directly to magnetic tape via the tape drive, functioning as an output medium.

Because magnetic tape supports reading (input), writing (output), and permanent data retention (secondary storage), all listed statements are correct.
