章节摘录

版权页：插图：However，it is difficult and tedious to communicate with the computer using this type of language.The hardware alone is very difficult to use.To circumvent the problem，difierent translatorprograms and other utilities were gradually developed known as system programs.NOW the question arises who is going to control these software and the machine? The answeris certainly the OS，as it implements certain frequently used functions that assist in program creation，management of files and control of I／0 devices.In this context，a computer without an 0S mav becompared to a bus without a driver and conductor.Such a bus can still be run，but the passengersmight fight over who will drive it and where it should go.Similarly,the users of a computer systemwithout an 0S might fight over the right to use the computer resources.As this text proceeds，we will see how crude the hardware is and how much control of the softwareis required to manageall the system resources.viz.the hardware and the systemprograms.
