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)
