Types Of Operating Systems

Distributed OS
1. Most commonly found in super computers.
  1. Super computers are high-level computer systems with high capabilities.
2. Distributed processing.
  1. Parallel processing.
3. 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.
Embedded OS
1. Embedded OS is an operating system which is created for a specific device which performs only a few specific tasks.
2. For example a cash machine.
3. Embedded devices which use embedded OS are usually devices with low CPU and RAM because they're designed to be efficient.
Multi-tasking OS
1. Mostly found in general computers which you're most familiar with.
2. Computer systems have to deal with more processes meaning that generally more cores are needed to perform the processes.
3. Allows the computer to switch between different programs performing different tasks.
Multi-user OS
1. Allows the computer system to allow multiple users from multiple accounts to access at one time.
2. 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.
3. Most commonly used on mainframe computer systems.
Real time OS
1. Firstly designed to ensure a task is carried out within a guarenteed time.
2. The expected response time to a task is within a small fraction of a second.
3. Many safety critical computer systems use real time OS.
