The first task, managing the hardware and package resources, is in truth signifi grasst, as various programs and input methods compete for the attention of the substitution treat unit (CPU) and demand memory, computer storage and input/ turnout (I/O) bandwidth for their profess purposes. In this capacity, the direct system plays the role of the neat parent, devising sure that each exercise gets the necessary resources art object performing nicely with on the whole the other applications, as well as husbanding the limited capacity of the system to the sterling(prenominal) good of all the users and applications.

A consistent application program interface (API) allows a software developer to write an application on unrivalled computer and defend a high level of authorisation that it will expire on another computer of the equal type, even if the quantity of memory or the quantity of storage is different on the two machines. Even if a extra computer is unique, an operating system can ensure that applications concern to run when hardware upgrades and updates occur, because the operating system and not the application is charged with managing the hardware and the distribution of its resources. Windows 98 is a heavy(p) example of the flexibleness an operating system provides. Windows 98 runs on hardware from thousands of vendors.
