Linux provides no kernel options or parameters that disable the deferred page allocation behavior of its demand paging implementation. Therefore, real-time applications must take three extra steps to assure all the memory the application has requested is ready for use before entering operation.On the other hand, even though a real-time capable Linux kernel is not a hard RTOS, its performance can be sufficient for many real-time applications without requiring speciality hardware or software.Linux has a more performance optimized scheduler, which prioritises foreground tasks with the aim of improving overall device performance. As this is less deterministic than an RTOS, it is difficult to know when a task is going to be completed.
Is the Linux scheduling policy adequate for hard real-time systems : Linux is not a hard real-time operating system, as it does not guarantee that a task will meet strict deadlines. The kernel can suspend a task when its time slice has completed, and it can remain suspended for an arbitrarily long time (for example, when an interrupt is getting serviced).
Why Linux can’t replace Windows
One reason I think Linux (the kernel) would be a poor fit as a Windows replacement is the lack of a stable driver ABI. Linux is a monolithic kernel and all the drivers are expected to be part of it. It is a model that works because it fully embraces open source and community driven development.
Why we don t use Linux : As a desktop operating system, Linux has been criticized on a number of fronts, including: A confusing number of choices of distributions, and desktop environments. Poor open source support for some hardware, in particular drivers for 3D graphics chips, where manufacturers were unwilling to provide full specifications.
When the linux desktop doesnt have to wait on resources, it feels extremely fast. Even low mem/cpu desktops will feel quicker when things can respond without interruptions, micro stutters, hardware pauses, and audio/gfx lags are gone. How Hard Is Linux to Learn Linux code isn't hard to learn if you have some basic tech knowledge and an understanding of operating systems. If you're an analytical and logical thinker, it will be easy to learn basic commands and syntax. Even if you're a tech newbie, you can still learn Linux.
Why Linux doesn t have virus
Linux is designed with strong security features, making it safe even without a firewall when not connected to a network. One of these security measures is called Security-Enhanced Linux (SELinux), which includes special tools and changes to the core of the system to enforce security policies.Linux scheduler:
Linux handles this rather better. It actively prefers to keep threads on the same core for as long as there are no scheduling conflicts on that core. So a single-threaded workload on Linux will usually stay on the same core for several seconds at a time, if not longer.Pre- emptive scheduling
Explanation : Pre- emptive scheduling is the most suitable scheduling scheme for real time operating systems as it can always preempt other processes based on priority. The question is not whether Linux will become market leader in desktop computing. Of course it will; it's the very last niche in computing that it doesn't dominate yet. It's just that this future might be less pleasant than we would think….
Will Linux ever be better than Windows : Yes. Linux is faster and less resource-intensive than Windows. Linux also doesn't contain bloatware like Windows does. That means it boots up and completes tasks much faster.
Why is Linux not popular : Linux has been criticized for a number of reasons, including lack of user-friendliness and having a steep learning curve, being inadequate for desktop use, lacking support for some hardware, having a relatively small games library, and lacking native versions of widely used applications.
What are 3 disadvantages of using Linux
What are the Disadvantages of Linux OS
Advantages
Disadvantages
License expenses
Software interoperability
Backward Compatible
Unsufficient standardization
Easy to install & update & manage
Lack of Commercial Support
Lightweight
Poor Gaming Support
Linux is faster and less resource-intensive than Windows. Linux also doesn't contain bloatware like Windows does. That means it boots up and completes tasks much faster. If you want a faster OS, or if you want to extend the life of an older PC, Linux is a great choice.Linux offers advantages over Windows and Mac, like greater customization and flexibility, robust security features, and being open source. Linux is also more resource-efficient, making it suitable for older hardware and server environments.
Why is learning Linux so hard : While this operating platform is functional, reliable, and secure it is hard for the common users to navigate because there are so many distributions and it isn't compatible with all desktop operating systems and design software. Also, the graphical user interface is not as interactive.
