Types Of Operating Systems

Types Of Operating Systems

1. Distributed OS

   • Most commonly found in super computers.
     • Super computers are high-level computer systems with high capabilities.
   • Distributed processing.
     • Parallel processing.
   • A single task is broken into many smaller tasks which require less power. One computer will hold one task each and once processed will re-gather all the finished tasks at the end.

2. Embedded OS

   • Embedded OS is an operating system which is created for a specific device which performs only a few specific tasks.
   • For example a cash machine.
   • Embedded devices which use embedded OS are usually devices with low CPU and RAM because they're designed to be efficient.

3. Multi-tasking OS

   • Mostly found in general computers which you're most familiar with.
   • Computer systems have to deal with more processes meaning that generally more cores are needed to perform the processes.
   • Allows the computer to switch between different programs performing different tasks.

4. Multi-user OS

   • Allows the computer system to allow multiple users from multiple accounts to access at one time.
   • Multi-user OS must allow more than one person to share a computer’s resources at the same time for it to be classified as multi-user OS computer system.
   • Most commonly used on mainframe computer systems.

5. Real time OS

   • Firstly designed to ensure a task is carried out within a guarenteed time.
   • The expected response time to a task is within a small fraction of a second.
   • Many safety critical computer systems use real time OS.
