A computer takes 50 nanoseconds to do an 221 addition. How many addition can it do in 1 second?

A computer takes 50 nanoseconds to do an 221 addition. How many addition can it do in 1 second? Correct Answer 20 million

আমরা জানি, 1 ন্যানো সেকেন্ড = 10 - 9  সে.50 ন্যানো সেকেন্ড = (50×10 - 9)  সে. = (5×10×10 - 9)  সে. = 5×10 - 8 সে. কম্পিউটারটি 5×10 - 8 সেকেন্ডে করে 1 টি যোগ .:. কম্পিউটারটি 1 সেকেন্ডে করে 15×10 - 8 = 1085 = 2×1085×2 = 2×10810 = 2×107 = 2 কোটি যোগ

Consider a single-level page table system. with the page table stored in the memory. If the hit rate to TLB is 80%, and it takes 15 nanoseconds to search the TLB. and 150 nanoseconds to access the main memory, then what is the effective memory access time, in nanoseconds ?
In a computer system, memory mapped access takes 100 nanoseconds when a page is found in TLB. In case the page is not TLB, it takes 400 nanoseconds to access. Assuming a hit ratio of 80%, the effective access time is:
A computer takes 50 nanoseconds to do an addition. How many additions can it do in 1 second?
Mr.Rohan while helping the students of Class IV in adding and subtracting fractions observed that several students are not able to complete the addition of two improper fractions. He gave a small test with questions from the addition of proper fractions (one item of addition of two similar fractions, three items from the addition of proper and improper fractions, and four items from the addition of improper fractions). He analyzed the responses of each student and found that nearly 45% of students were not clear in adding proper with improper fractions which were affecting their performance in adding two improper fractions. He, therefore, focused on developing the understanding of improper fractions and their addition with proper fractions after which he proceeded to teach the addition of two improper fractions. Which kind of assessment is depicted by this situation?
