The Purpose of Operating Systems. 

An operating system is software that reinforces a computers primary functions. It also manages computer hardware and software resources and provides normal services for computer programs. An operating system is an important component of the system software in the computer system. Programs usually require an operating system to work.
Five common operating systems used are Ubuntu, Android, Mac OS X, IOS and Windows. 

Machine and peripheral management. 

Machine & peripheral management

Peripheral management controls peripheral devices. It does this by sending them commands in a way they can understand (their own language). A driver is the software routine that knows how to deal with each device. The device driver is installed into the system when the new peripheral is added. The operating system deals with the computer's peripherals using the software drivers for the devices. The operating systems controls the whole machine and all the components there and this includes peripherals such as keyboards, mouses and printers. 

Security.

McAfee Security.

Security for computers includes protecting the systems main things such as memory and important operating systems and programmes. It also protect personal things that are stored on the computer too. If a computer is ran without security it is more likely to be hacked and also get viruses. Security can be anything between passwords to having a security programme such as McAfee. 


File management.

File Management.

File management can be said to be manipulation of documents in a file stored on a computer. It is a system software and it acts as a master control for all activity that happens within the computer system. The system is what organises and keeps track of the files. files are managed on their location and storage device. File management gives a way to open and save files into folders and makes it easier to organise your work.




Device drivers.

Windows Device Driver.

A device driver is a program on the computer that is installed to operate and also control specific devices that are plugged into the computer. An example of these devices could be a printer or a keyboard. The device driver essentially turns the more general input and output orders of the operating system into messages that the device can understand. A device driver can also simplify programming.
