Types of Operating Systems
Single User / Multitasking OS
Network OS
Distributed OS
Cloud OS
Single User / Multitasking
Most Common
Users can multitask
E.g. Windows, MacOS
Can work on relatively cheap computers
Tend not to be very complex for the end user
Network Operating System
Runs on a server and allows to manage data, users, groups, security, applications and other networking functions
Allow shared file and printer access among multiple computers in a network
Many users connect to one computer, each user has a unique session
E.g. Microsoft Windows Server, Unix, Linux, Novell NetWare
Advantages
Centralised Servers are highly stable
Security is server managed
Upgrades to new technologies and hardware can be easily integrated into the system
Remote access to servers is possible from different location and types of systems
Disadvantages
High cost of buying and running a server
Dependency on a central location for most operations
Regular maintenance and updates are required
Disitributed OS
Use multiple central processors to serve multiple real-time applications and multiple users
Data processing jobs are distributed among the processors accordingly
A User at one site may be able to use the resources available at another
Speed up the exchange of data with another via electronic mail. If one site fails in a distributed system, the remaining sites can potentially continue operating
Better service to the customers. Reduction of the load on the host computer
Reduction of delays in data processing
Cloud Operating System
Designed to operate within cloud computing and virtualisation environments
Manages the operation, execution and processes of virtual machines, virtual servers and virtual infrastructure as well as the back-end hardware and software resources
Primarily manages the operation of one or more virtual machines within a virtualised environment
