MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Although most modern supercomputers use the Linux operating system, each manufacturer has made its own specific changes to the Linux-derivative they use, and no industry standard exists, partly because the differences in hardware architectures require changes to optimize the operating system to each hardware design.

Detailed explanation-2: -Proprietary Unix operating systems (and Unix-like variants) run on a wide variety of digital architectures, and are commonly used on web servers, mainframes, and supercomputers. In recent years, smartphones, tablets, and personal computers running versions or variants of Unix have become increasingly popular.

Detailed explanation-3: -Linux is Flexible & Scalable Linux, as noted above, is much more lightweight than other operating systems. As a result, Linux can be configured to run on just about any hardware imaginable – everything from the fastest supercomputers in the world to a smartwatch.

Detailed explanation-4: -Whether it’s a physical server or a cloud server, most of them are Linux operating systems. More than 90% of the top 1000 websites in the world use Linux as the dominant system. Why are most servers Linux-based? Linux is a POSIX-based multi-user, multi-tasking operating system with multi-threaded and multi-CPU support.
