There are twobasi ways of attackia the problem: eiem: to reduce the cost ofusiQ dynami memory or to reduce the usage ofdynami memory. The problem can also be attacked atdi ferent levels,il . the operatiz system level, theiz6RLQGz-'268 level, and the software archi"82'z e anddesiR level. Each of thei vesti8Qzways of attackia thedynami memory problem has is advantages and di68GR2zges.
