Homework Help Overview

The discussion revolves around calculating the time it takes for a computer to perform one calculation, given its performance rate of 6.9 × 10^7 calculations per second. The subject area involves concepts of time conversion and computational performance.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants explore the conversion of seconds to nanoseconds and question the interpretation of the calculations per second. There are attempts to derive the time for a single calculation and discussions about the correct method for conversion.

Discussion Status

Several participants have offered insights into the conversion process, with some suggesting different interpretations of the calculations. There is a mix of proposed answers, and the discussion is ongoing without a clear consensus on the final answer.

Contextual Notes

Participants are working within the constraints of the problem, focusing on the relationship between calculations per second and the time taken for individual calculations. The need for clarity in the conversion process is emphasized, but no definitive resolution has been reached.

Hey guys so I've been having some trouble with this question...

How many nanoseconds does it take for a computer to perform one calculation if it performs 6.9 × 10^7 calculations per second?
 
Physics news on Phys.org


How many nano seconds in a second?
 


10^9 I believe
 


So is the answer 69 nano seconds?
 


No. Just shift the decimals until you have something with ... x 109 sec since you can substitute that with nano seconds

The conversion to nanoseconds is the second step for the question. First you have to find the time for one operation, in seconds or any convenient unit. Then you can convert in nanoseconds.
The given value is not the time for one operation but the number of operation per second.
 


Alright so I got 14 nano seconds, I did 1 calculation/ seconds * seconds/ calculations per second which was 14 nano seconds :P
