How many units do we have in ALU?

In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU -- for example, one for fixed-point operations and another for floating-point operations.


What are directives in C?

Description. The preprocessor will process directives that are inserted into the C source code. These directives allow additional actions to be taken on the C source code before it is compiled into object code. Directives are not part of the C language itself.


Which of these is not output device?

Plotter, printer, and monitor are output devices but a touch screen is not an output device. An output device is any piece of computer hardware equipment that converts information into human-readable form. It can be text, graphics, tactile, audio, and video.


What is the capacity of computer?

Storage capacity refers to how much disk space one or more storage devices provides. It measures how much data a computer system may contain. For an example, a computer with a 500GB hard drive has a storage capacity of 500 gigabytes A network server with four 1TB drives, has a storage capacity of 4 terabytes.


Where do we use microprocessor?

Microprocessor-based systems are thus found everywhere today and not just in computers and smartphones: in automatic testing of products, speed control of motors, traffic light control, communication equipment, television, satellite communication, home appliances, such as microwave oven, washing machine, gaming


Why is called preprocessor directive?

Preprocessing is an initial phase to process text before compilation. Preprocessor directives are lines of the source file where the first non-whitespace character is # , which distinguishes them from other lines of text.
