Types of Operating Systems | Computer Science

Distributed OS

can coordinate the processing of a single job across multiple computers to improve performance and resource sharing.

Multi-tasking system

A single processor can appear to do more than one task simultaneously by scheduling processor time among multiple processes, allowing efficient use of resources.

multi user OS

Lots of users with their own terminals access the mainframe’s CPU and each gets a time slice

Mobile Operating Systems

The main OS handles the user interface and running applications while a low-level proprietary OS is used for handling the hardware and special features such as cellular connectivity and wifi

Open source operating systems

Free software which allow for major customisation and fine-tuning to suit devices and additional features

Embedded Operating System

Runs simple programs held in ROM with minimal features

Real time Operating Systems

Some operating systems must operate in real time and respond extremely quickly to inputs

BIOS (Basic Input Output System)

Stores bootstrapper in ROM, Loads OS into RAM when the computer is turned on
