Types of Operating System
Distributed
sits in front of and controls a host of different computers
this may me connected across a LAN or series of LANs.
Very different then having many computers if different individual operating system installed
They are designed to spread different tasks across a range of computers to make use of their combined processing power so that greater performance is achieved
The operating system coordinates and controls the processing of all computing involved
All Users appear as if they are using a single computer
Behind the scenes the operating system is making use of a great deal of different resources to provide a much more powerful system.
Embedded
Is designed for a single device which may just has a small number of jobs to perform
Devices such as TV's, mobile phones and dishwashers are all devices which will be control by and ansystem
Embedded operating systems are a type of operating system, which control embedded systems
Multitasking
A multi-tasking operating system is the kind that you might find on a home PC.
The home PC is likely to have multiple programs open at the same time and millions of processes needing to be executed from different programs in the same space of time.
As PCs are likely to have a limited number of CPU cores they will not be able to execute all of these processes at once taking it in turns to have their tasks processed
A multi-tasking operating system is specifically designed to enable the management of these processes so the CPU can be given the right takes at the right time to make it appear that all of the programs are running quickly and at the same time
Multi-user
A multi-user operating system is one which is designed to enable several users to all access a system reassures at the same time
You home PC, although you may have different accounts for your family members, will not allow two people to be logged on at once
These spcialies operating systems are likely to be found on a mainframe computers
Real-Time
These types of operating systems are specifically designed to perform tasks within a definitive period of time.
This is in case anything goes wrong with anything the OS can immediate shut it down
Aeroplane systems will also need to respond to events such as turbulence within a fraction of a second to ensure safety when flying
Real-time operating system are optimised to process priority jobs insanely quickly.
They will also have a fail safe features so that in event that a piece of hardware failing there is another hardware component that cant be used
