In computer programming, housekeeping can refer to either a standard entry or exit routine appended to a user-written block of code (such as a subroutine or function, sometimes known as a function prologue and epilogue) at its entry and exit or, alternatively, to any other automated or manual software process whereby a computer is ''cleaned up'' after usage (e.g. freeing resources such as virtual memory). This might include such activities as removing or archiving logs that the system has made as a result of the users activities, or deletion of temporary files which may otherwise simply take up space. Housekeeping can be described as a necessary chore, required to perform a particular computer's normal activity but not necessarily part of the algorithm.〔("Housekeeping" ), ComputerHope.Com. Accessed July 20, 2009〕 For cleaning up computer disk storage, utility software usually exists for this purpose such as data compression software - to "shrink" files and release disk space and defragmentation programs - to improve disk performance.〔("Basic Computer Housekeeping Tips" ). Accessed July 20, 2009〕 == Examples == Housekeeping could include (but is not limited to) the following activities: * Saving and restoring program state for called functions (including general purpose registers and return address) * Obtaining local memory on the stack * Initializing local variables at the start of a program or function * Freeing local memory on the stack on exit from a function * Garbage collection * data conversion * Backup and/or removal of un-needed files and software * Execution of Disk maintenance utilities (e.g. ScanDisk, Harddrive Defragmenters, Virus Scanner) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Housekeeping (computing)」の詳細全文を読む スポンサード リンク
