d) None of these

Answer 1

The percentage of times a page number is found in the TLB is known as the Hit ratio.

Step-by-step explanation:

The percentage of times a page number is found in the TLB is known as Hit ratio. The TLB (Translation Lookaside Buffer) is a cache that stores a mapping of virtual page numbers to physical page numbers. When a program accesses memory, the processor checks the TLB to see if the virtual page number is present. If it is, this is called a TLB hit. If the virtual page number is not found in the TLB, it is called a TLB miss. So, the percentage of times a page number is found in the TLB is referred to as the Hit ratio.
