Question

Q. Operating systems are the most indispensable components of the software interface between users and the hardware of their computer systems. Explain.

Answer 1

Operating system is nothing to combine the software and hardware and do the system operations smoothly.

actually hardware can understand binary data which is 0 or 1 which means 0 means 0 voltage and 1 means 5 voltage like in trasistors based on the power on or power off hardware will work.if one hand hardware is there in other hand software is there then there is no use both are indepenent to make one by one dependent operating system will do this kind of process.the actually process of any program execute it takes few steps for example if we watch some video in the computer or in mobile first we need to open the video that mean we are access the video memory location then the whole data present at secondary memory which is harddrive or pendrive or sdcard then it moves to device main memory because every process must process in cpu then only we get the output bu cpu can't able to read the memory in secondary memory so thats why it moves to mainmemory then cpu can process the data which is present in the main memory then do certain io operations these all process can't do by hardware but process done in hardware.to do this kind of process operating system tack care all this operations in the hardware so without operaing system there is no chance to work any device.so both are dependent on operating system
