operating system manages memory access to ensure
that one application doesn??™t try to use memory that??™s
being used by another application. The operating
system also controls access to the CPU.
You??™ve just purchased a new computer that uses
a dual-core Intel CPU. The computer came prebundled
with Windows XP Home. Can you use
Linux on this system?
Yes. Because the operating system and computer
hardware are modular, you can remove Windows and
install Linux. Likewise, you could also repartition
the hard disk drive and install Linux on it, creating a
dual-boot system.
You are a computer programmer. You need to access
the hard disk drive to write data to a file. What is the
most efficient way to do this?
You can link to an operating system library in your
programming code and call functions from it that will
allow you to easily create a file, write data to it, and
close the file when you??™re done.
