Operating Systems
- What is an operating system?
- the low-level software that supports a computer's basic
functions, such as scheduling tasks and controlling
peripherals.

- What is the purpose of an operating system?
- An operating system (OS) is software that manages
computer hardware and software resources and
provides common services for computer programs.
The operating system is an essential component of the
system software in a computer system. Application
programs usually require an operating system to
function.

- What are the most
common operating systems
in use today?
- What functions do operating systems have?
- Provides a user interface, booting the computer, file
management, managing the hardware and software,
performs basic computer tasks and handles system
resources such as computer's memory and sharing
of the central processing unit (CPU) time by various
applications or peripheral devices.

- What is a GUI?
- In computing, a graphical user
interface is a type of interface that
allows users to interact with
electronic devices through graphical
icons and visual indicators such as
secondary notation, as opposed to
text-based interfaces, typed
command labels or text navigation.

- Advantages to a GUI?
- - it can be user-friendly and speed up the user's
work, it can be more attractive for non-technical
people, in general it looks more professional.

- Disadvantages of a GUI?
- when it is not properly built, it can be very difficult
to work with, it generally requires more memory
resources than a non-graphical one, it might require
the installation of additional software, e.g., the
"runtime environment" in the case of java,
depending on the programmer it might require more
time to be implemented.

- What is a CLI?
- The CLI was the primary
means of interaction with
most computer systems until
the introduction of the video
display terminal

- Advantages of a CLI?
- Control every aspect of your computer, it is
fast, you can do things at different times, such as
setting a time for a download script. You could
choose to download a new program when you
are sleeping, everything in one place, good for
speed if you have a slow computer, less graphics
means less RAM used up while you perform
tasks, you can use scripting language and even
other programming languages, such as C
(depending on which command line you use.)

- Disadvantages of a CLI?
- Lots to learn, not GUI
(Graphic User Interface),
many of the advantages
are mainly for Linux, not
so much for Windows.
