Round-robin scheduling
Round-robin scheduling (Figure 7.151) allocates each task an equal share of the CPU time. In its simplest form, tasks are in a circular queue and when a task's allocated CPU time expires, the task is put to the end of the queue and the new task is taken from the front of the queue.

Operating system is
An OS or operating system is the fundamental software that allows us to interact with and use our computers and smartphones. With this powerful tool, you can juggle between applications, watching movies, writing documents and many other tasks.

See lessThe SJF algorithm executes first the job
Shortest Job First (SJF) is an algorithm in which the process having the smallest execution time is chosen for the next execution. This scheduling method can be preemptive or non-preemptive. It significantly reduces the average waiting time for other processes awaiting execution.

See lessIn which way(s) a macro processor for assembly language can be implemented:
Macro processors can be implemented in a number of ways, including as an independent two-pass processor, an independent one-pass processor, or as a processor incorporated into pass 1 of a standard two-pass assembler.

See lessThe advantage(s) inherent to using high level languages is (are)
Using high-level languages offers several advantages. They are easier to learn and understand, reducing the learning curve for new programmers. High-level languages also provide built-in functions and libraries, increasing productivity.

Addressing modes
The addressing mode is the method to specify the operand of an instruction. An effective address is the location of an operand which is stored in memory. Here are the addressing modes discussed: Immediate: The operand is included in the instruction.
