Provides a consistent environment for other software to execute
Operating System (OS) commands.
Provides users with an interface with the computer so
that they can send commands (input) and receive
feedback or results (output).
1) Procesor The Operating System (OS) interacts with what resources?
2) Devices
3) Memory
4) Input/Output
5) storage
Keyboard or mouse Input devices
Application Is software that is written to supplement the commands
available on a particular operating system (OS).
Drivers Extremely specific software written for the purpose of instructing
a particular OS on how to process a piece of hardware.
Source Code Is the actual code that defines how a piece of software works.
Is a program that runs on top of the OS and allows the user to
issue commands
Shell
through a set of menus or another interface. Make an OS easier
to use by changing the user interface.

Is a method by which a person communicates with a computer
using graphical
Graphical User Interface (GUI) images, icons, and methods other than text. Allow a
user to use a mouse, touchpad, or another mechanism
(in addition to the keyboard) to interact with the
computer to issue commands.
Is any group of computers that have a communication
Network
link between them. Allow computers to share
information and resources quickly and securely.
Is a multitasking method that depends on the
application itself to be responsible for using the
Cooperative Multitasking
processor and the freeing it for access by other
applications. If any
application locked up while using the processor, the
application was unable to free the processor to do
other tasks and the entire system, usually forcing
reboot.
Is a multitasking method in which the OS allots each
application a certain amount of processor time and then
Preemptive Multitasking forcibly takes back control and gives another application
or task access to the processor. This means that if an
application crashes, the OS takes control of the
processor away from the locked application and
passes it on to the next application, which should be
unaffected.
Is the ability of a single application to have multiple
Multi-threading
requests in to the processor at one time.
Advanced RISC Machine ARM
RISC Reduced Instruction Set Computing
Operating systems that use a Reduced Instruction Set
ARM
Computing (RISC) instruction set commonly found on
tablet and phone processors.
Random Access Memory RAM
Is used to describe the amount of memory installed and
Random Access Memory accessible for an operating system. Used to hold its
(RAM)
operating code, as well as the programs you open on
