In computing system generation or sysgen is the process of creating a particular unique instance of an operating system by combining user-specified options and parameters with manufacturer-supplied general-purpose program code to produce an operating system tailored for a particular hardware and software environment.
A large general-purpose program such as an operating system has to provide support for all variations of Central processing unit (CPU) that it might be run on, for all supported main memory sizes, and for all possible configurations of input/output (I/O) equipment. No one installation requires all this support, so system generation provides a process for selecting the options and features actually required on any one system.
Language processor is a software that bridges the execution gap. Input is the source program and output is the target code. Types of language processor are : assembler, compiler and interpreter.
Assembler: It converts assembly language program to machine language which computer understands. They produce executable code. Compiler: It converts a high language program to machine language program. Translation process should also tell about the presence of errors in the source program. Interpreter: It bridges the execution gap without generating the machine language code. In this, there is no target code. It executed the code line by line.
In which addressing mode the effective address of the operand is the contents of a register specified in the instruction and after accessing the operand, the contents of this register is incremented to point to the next item in the list?
Auto Indexed (increment mode): Effective address of the operand is the contents of a register specified in the instruction. After accessing the operand, the contents of this register are automatically incremented to point to the next consecutive memory location.
The memory allocation scheme subject to "external" fragmentation is
For a specific file to copy from one disk to another disk, Copy command should be used. Diskcopy copies whole disk into new disk. Time command is to display system time and Rename command just changes the name of a file.
What is the name of the operating system for the laptop computer called MacLite?
Oz is a concurrency-oriented language, as the term was introduced by Joe Armstrong, the main designer of the Erlang language. A concurrency-oriented language makes concurrency easy to use and efficient. Oz supports a canonical graphical user interface (GUI) language QTk.
