How are operating systems making the computers more efficient?
Operating systems are also designed to give programmers a common set of commands to consistently interact with the hardware. These commands make a programmer’s job easier by reducing program complexity and making it faster to write software while minimizing the possibility of errors in code.
What makes up an operating system?
An operating system, or “OS,” is software that communicates with the hardware and allows other programs to run. It is comprised of system software, or the fundamental files your computer needs to boot up and function. Common desktop operating systems include Windows, OS X, and Linux.
