The term 'page traffic' describes
Answer: C) the movement of pages in and out of memory.
In an Operating System, Page Traffic refers to the movement or transfer of pages between main memory (RAM) and secondary storage (Hard Disk or Swap Space).
When a required page is not available in RAM, a Page Fault occurs. The operating system may bring that page from disk into RAM. If RAM is full, another page may need to be moved out to make space.
This continuous movement of pages between RAM and disk is called Page Traffic.
- A: Number of pages currently present in memory.
- B: Number of pages needed for a particular page request.
- C: Movement of pages in and out of memory — Correct.
- D: Number of program pages loaded in memory.
Operating System मा Page Traffic भन्नाले Main Memory (RAM) र Secondary Storage (Hard Disk वा Swap Space) बीच Pages हरूको आवतजावत वा स्थानान्तरणलाई जनाउँछ।
जब कुनै आवश्यक Page RAM मा उपलब्ध हुँदैन, तब Page Fault हुन्छ। यस्तो अवस्थामा Operating System ले आवश्यक Page लाई Disk बाट RAM मा ल्याउँछ। RAM भरिएको छ भने नयाँ Page राख्न अर्को Page लाई बाहिर सार्नुपर्ने हुन सक्छ।
यसरी RAM र Disk बीच Pages हरूको निरन्तर स्थानान्तरण हुने प्रक्रियालाई Page Traffic भनिन्छ।
Exam Tip: Page Traffic = Movement of Pages In and Out of Memory.
