पर्यायी उत्तरे :

The correct answer is Option A (IV, III, II, I).

Key Points:
• Operating systems are tailored for specific hardware architectures ranging from early personal computers to embedded systems and mobile devices.
• Option 1 is correct with the matching sequence: a-IV, b-III, c-II, d-I.
• Detailed breakdown:
• Symbian (a) was widely used in early smart cell phones (IV) particularly by Nokia.
• Palm OS (b) was built specifically for hand-held devices like Personal Digital Assistants / PDAs (III).
• Windows CE.NET (c) is an OS designed for embedded real-time devices (II).
• DOS (d) was the primary operating system used for early IBM PCs (I).
• Identifying even one iconic match (such as DOS for IBM PC or Symbian for early smartphones) allows rapid elimination of wrong options.
• Use elimination technique on 'Match the Following' questions to increase speed and accuracy.
• Key Takeaway: Remember: DOS = IBM PC; Symbian = Smart Cell Phones; Palm = PDAs; Windows CE.NET = Embedded/RTOS.
