A resource allocATion scheme (usually for memory). Best Fit tries to determine the best place to put the new dATa. The definition of ' best' may differ between implementATions, but one example might be to try and minimise the wasted space AT the end of the block being allocATed - i.e. use the smallest space which is big enough. By minimising wasted space, more dATa can be allocATed overall, AT the expense of a more time-consuming allocATion routine. Compare First Fit. (1997-06-02)
