O.s act as an interface between user and computer .os act as host
As a host, one of the purposes of an operating system is to handle the details of the operation of the hardware Source: CoolInterview.com

PURPOSE:An operating system is the framework that allows you to communicate with computer hardware in an interactive way. Without this, you would not be able to tell the computer to do anything and it would have any instructions to follow. This is why it is important for a computer to have an operating system.

Operating system controls and coordinates the use of the hardware among the various applications programs for various uses. Operating system acts as resource allocator and manager. Since there are many possibly conflicting requests for resources the operating system must decide which requests are allocated resources to operating the computer system efficiently and fairly. Also operating system is control program which controls the user programs to prevent errors and improper use of the computer. It is especially concerned with the operation and control of I/O devices.

briefly Operating system is describe as ;-
1. Governor
2. Resource Allocator, etc

so it easily ,efficiently and effectively perform user's task and reduce some of its overall time consumption.
At last, OS simply makes computer user friendly. Source: CoolInterview.com

Basically OS is a resource allocator & interface b/w user and hardware like we can take example of our language via which we interact wid others that language is interface b/w us.Os provides only environment practically everything comes from hardware. Source: CoolInterview.com

Operating System Functions

1.It manages the hardware and software resources of the system. In a desktop computer, these resources include such things as the processor, memory, disk space and more (On a cell phone, they include the keypad, the screen, the address book, the phone dialer, the battery and the network connection).

2.It provides a stable, consistent way for applications to deal with the hardware without having to know all the details of the hardware.

An operating system is the framework that allows you to communicate with computer hardware in an interactive way. Without this, you would not be able to tell the computer to do anything and it would have any instructions to follow. This is why it is important for a computer to have an operating system .In early days without OS so much problems where faced like acessing or getting output it takes two days. To make it much more efficient OS is used.
