os Various Times related to the Process

1. Arrival Time

The time at which the process enters into the ready queue is called the arrival time.

2. Burst Time

The total amount of time required by the CPU to execute the whole process is called the Burst Time. This does not include the waiting time. It is confusing to calculate the execution time for a process even before executing it hence the scheduling problems based on the burst time cannot be implemented in reality.

3. Completion Time

The Time at which the process enters into the completion state or the time at which the process completes its execution, is called completion time.

4. Turnaround time

The total amount of time spent by the process from its arrival to its completion, is called Turnaround time

5. Waiting Time

The Total amount of time for which the process waits for the CPU to be assigned is called waiting time.

6. Response Time

The difference between the arrival time and the time at which the process first gets the CPU is called Response Time.

Computer Architecture vs Computer Organization

Computer Architecture: Definition: Computer architecture is the conceptual design and fundamental operational structure of a computer system. It defines the way in which the various hardware and software components work together to form a complete computer system. Focus: It primarily deals with high-level design decisions, such as the instruction set architecture (ISA), the organization of memory, and the design of the CPU. It is concerned with the interface between the hardware and the software. Example: An example of a computer architecture decision is the choice of a specific instruction set (e.g., x86, ARM) and the design of the system's memory hierarchy. Goal: The primary goal of computer architecture is to provide a framework for building efficient and effective computer systems that meet the performance, power, and cost requirements of various applications. Computer Organization: Definition: Computer organization is more specific and deals with the low-level details of t...
