MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A distributed operating system (DOS) is an essential type of operating system. Distributed systems use many central processors to serve multiple real-time applications and users. As a result, data processing jobs are distributed between the processors. It connects multiple computers via a single communication channel.

Detailed explanation-2: -Parallel processing is a method in computing of running two or more processors (CPUs) to handle separate parts of an overall task. Breaking up different parts of a task among multiple processors will help reduce the amount of time to run a program.

Detailed explanation-3: -Some examples of a multi-user OS are Unix, Ubuntu, MacOS, Windows and all Linux based OS. Multi-user operating systems were originally used for time-sharing and batch processing on mainframe computers.

Detailed explanation-4: -Overview. The parallel processing system is designed to speed up the execution process of programs by dividing them into multiple segments and processing them simultaneously. These systems are called multiprocessor systems or tightly coupled systems.

Detailed explanation-5: -Distributed processing means that a specific task can be broken up into functions, and the functions are dispersed across two or more interconnected processors. A distributed application is an application for which the component application programs are distributed between two or more interconnected processors.
