Hardware requirements for analysing depend on the type of analysis. When analysis involves large amounts of data or complex simulations, the hardware must perform a large number of computations very quickly and with a high degree of precision. If the simulations are complex, such as in scientific applications, then a supercomputer or mainframe may be required.

Large amounts of storage are needed to receive and retain data over a period of time. If the primary storage (memory) and secondary storage (storage) resources are abundant, then fast processing is possible.

Fast processing is needed to complete the many calculations often required for analysis. This is performed by the central processing unit (CPU). Applications requiring complex analysis use parallel processing. This is the simultaneous processing of instructions using multiple processors or CPUs. Parallel processing is much faster than using one CPU.
