DSSSB TGT CS Mock 02 – Question 110

Question:

Which of the following cache write policies writes updated data simultaneously to both the cache and the main memory?

निम्नलिखित में से कौन-सी कैश राइट पॉलिसी अपडेट किए गए डेटा को कैश और मुख्य मेमोरी दोनों में एक साथ लिखती है?

Options:

  • Write-through
  • Write-back
  • Write-allocate
  • No-write-allocate
  • राइट-थ्रू (Write-through)
  • राइट-बैक (Write-back)
  • राइट-एलोकेट
  • नो-राइट-एलोकेट

Correct Answer: a)

Explanation:

In a Write-through cache, every write operation to the cache is immediately and synchronously updated in main memory. In Write-back, updates are written to main memory only when the dirty cache line is evicted (Option a).

Write-through पॉलिसी में प्रत्येक राइट ऑपरेशन तुरंत कैश और मुख्य मेमोरी दोनों में निष्पादित होता है (विकल्प a)।
