Operating Systems

Operating Systems

1. Managing Resources

   • instructions are different for each piece of hardware
   • Each PC has a different combination of CPU, hard disk, memory manager, graphics card etc.
   • An operating system talks directly to the hardware
   • software is written for the OP instead of the hardware

2. They are vital to modern computing systems

   • They perform a range of functions such as: managing resources, processes, peripherals, memory and provide an interface

3. Advantages of OS

   • if a program is written in C++, it can be compiled for windows, Linux, mac or android.
     • it will then run on any machine that can run the operating system
   • as a programmer, you don't need to worry about what hardware the user has, or how security is handled
