Question

If a page number is not found in the TLB, then it is known as a :

a) TLB miss
b) Buffer miss
c) TLB hit
d) TLB hit

Answer 1

When a page number is not found in the TLB, it is called a TLB miss. The TLB is a cache for memory translations that increases efficiency, whereas a miss requires a slower access to the page table.

Step-by-step explanation:

If a page number is not found in the Translation Lookaside Buffer (TLB), it is known as a TLB miss. The TLB is a cache used to improve virtual memory translation speed by keeping a short list of recent translations from the virtual memory space to the physical memory space. When the processor tries to access data in memory and the page number is not found in the TLB, it has to access the page table, which is slower, resulting in a TLB miss. A TLB hit, on the other hand, occurs when the page number is found in the TLB, allowing for faster memory access.
