Everything that you watch on the internet today run on the operating system. Certain software runs on an operating system. Because of that, the element of compatibility is very important.

Software and operating systems

Software makers take the issue of the operating system very seriously. Because of that, it is common to see some products that run on a specific operating system, but they cannot run on others.

If you have ever tried a download, you would see that the software would notify you on the type of ground and software that it can support.

You must always take that issue very seriously. You must know the kind of operating system that you are currently using and ensure that what you download is compatible with that operating system.

However, it is common to see such software developers creating an additional version of their software. When you are using the software, ensure that you use only those that are meant for your OS.


It is important to know that the operating system runs on the bit and you have to know whether it runs on 32 bit or 64 bit. You know this before you begin your download.

Functions of the operating system

Operating systems perform important functions and they include the following functions. They engage in file management.

  1. Processor management
  2. Memory management
  3. Security
  4. Device management
  5. Control of system performance
  6. Error detecting aids
  7. Job accounting as well as software use coordination and so on.

Perhaps the most important function that the system does for you is the issue of memory management. Primary or major memory is very important because it determines the efficiency of any system.

This is where storage is done in the system. If it is not well managed, safe and secure data could be lost. The operating system monitors the memory available such as those that are in use and those that are not in use.

Furthermore, the operating system shares the memories that are available in a system. It decides which system gets which memory. Without good memory management, you discover that the whole system would crash and that means a huge loss.

No person would want that experience and that is why such management is very important.
