1 1.6: Macduff first enters the play when the King and noblemen arrive at Inverness to stay with Macbeth. 2  He has no lines in the scene, which is noteworthy only because the scene is filled with the fawning of his fellows.
In computer programming, a task is a basic unit of programming that an operating system controls. Depending on how the operating system defines a task in its design, this unit of programming may be an entire program or each successive invocation of a program. Since one program may make requests of other utility programs, the utility programs may also be considered tasks (or subtasks).
A computer is a machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse. The processing of input to output is directed by the software but performed by the hardware. To function, a computer system requires four main aspects of data handling: input, processing, output, and storage. Input devices accept data in a form that the computer can use; they then send the data to the processing unit.
