Computer Science Calculators
Free online computer science calculators for algorithms, complexity, data structures, and more.
Download Time Calculator
Estimate how long it takes to download any file at different internet speeds. Enter file size in MB or GB and connection speed to get the result.
RAID Storage Calculator
Calculate usable storage and fault tolerance for RAID 0, 1, 5, 6, and 10. Compare all five configurations side by side for any number of drives.
Master Theorem Calculator
Enter a, b, and d for T(n) = aT(n/b) + O(n^d) to determine Big O complexity. Shows which case applies, the critical exponent, and algorithm efficiency class.
Sorting Algorithm Step Counter
Compare operation counts for bubble, insertion, selection, merge, and quicksort. Enter array size n to see step estimates and Big-O efficiency class.
