Define the following, Batch Processing, Multiprocessing, Bootstrapping, real-time processing and time sharing in operating system - Tech-n-savvy Blogger

a.         Batch Processing:

Batch processing is a general term used for frequently used programs that are executed with minimum human interaction. Batch process jobs can run without any end-user interaction or can be scheduled to start up on their own as resources permit.

B.        Multiprocessing:

Multiprocessor Operating System refers to the use of two or more central processing units (CPU) within a single computer system. These multiple CPUs are in a close communication sharing the computer bus, memory and other peripheral devices. These systems are referred as tightly coupled systems.

These types of systems are used when very high speed is required to process a large volume of data. These systems are generally used in environment like satellite control, weather forecasting etc.

c.         Bootstrapping:

A bootstrap is the program that initializes the operating system (OS) during startup. The term bootstrap or bootstrapping originated in the early 1950s. It referred to a bootstrap load button that was used to initiate a hardwired bootstrap program, or smaller program that executed a larger program such as the OS. The term was said to be derived from the expression “pulling yourself up by your own bootstraps,” starting small and loading programs one at a time while each program is “laced” or connected to the next program to be executed in sequence.

d.        Real-Time Processing:

Real-time data processing is the execution of data in a short time period, providing near-instantaneous output. The processing is done as the data is inputted, so it needs a continuous stream of input data in order to provide a continuous output. Good examples of real-time data processing systems are bank ATMs, traffic control systems and modern computer systems such as the PC and mobile devices. In contrast, a batch data processing system collects data and then processes all the data in bulk in a later time, which also means output is received at a later time.

Real-time data processing is also known as stream processing.

e.        Time Sharing:

A time sharing operating system is that in which each task is given some time to execute and all tasks are given time so that all processes run seamlessly without any problem. Suppose there are many users attached to a single system then each user has given time of CPU. No user can feel to have trouble in using the system.
