- Provides a user interface
a user interface is a
visual part of computer
aplication or operating
system though which the
user interacts wth a
computer or a software
- why does a computer have a user interface.?
- a computer has a user
interface so that without a
user nterface of some sort
the user would not be able to
interact/use the computer

- Facts about booting a computer
- in computing ,booting or booting up is the
instalazion of the computer system. The
system can be a computer or a computer
appliance. The booting process can be "hard",
after electrical power to the CPU is switched
from off to on (in order to diagnose
particular hardware errors), or "soft", when
those power-on self-tests (POST) can be
avoided. Soft booting can be initiated by
hardware such as a button press, or by
software command. Booting is complete
when the normal, operative, runtime
environment is attained.

- file
management
- The system that an operating system or
program uses to organize and keep track of
files. For example, a hierarchical file system is
one that uses directories to organize files
into a tree structure.
- Although the operating system
provides its own file management
system, you can buy separate file
management systems. These
systems interact smoothly with
the operating system but provide
more features, such as improved
backup proceduresand stricter file
protection.
- What is file management? The data that we work with on
computers is kept in a hierarchical file system in which
directories have files and subdirectories beneath them.
Although we use the computer operating system to keep our
image data organized, how we name files and folders, how
we arrange these nested folders, and how we handle the
files in these folders are the fundamental aspects of file
management. The operating system's organization of our
data can be enhanced by the use of cataloging programs,
which make organizing and finding image files easier than
simply relying on the computer's directory structure.
Another feature of catalog programs is that they can
streamline backup procedures for better file protection.
- The system that an operating system or
program uses to organize and keep track of
files. For example, a hierarchical file system is
one that uses directories to organize files
into a tree structure.
- The operating system performs basic computer
tasks, such as managing the various peripheral
devices such as the mouse, keyboard and
printers. For example, most operating systems
now are plug and play which means a device
such as a printer will automatically be detected
and configured without any user intervention.
- The operating system also handles system resources such as the
computer's memory and sharing of the central processing unit (CPU)
time by various applications or peripheral devices. Programs and input
methods are constantly competing for the attention of the CPU and
demand memory, storage and input/output bandwidth. The operating
system ensures that each application gets the necessary resources it
needs in order to maximise the functionality of the overall system.
