OBJECTIVE: I CAN EXPLORE, MANAGE, AND DEMONSTRATE A BASIC
UNDERSTANDING OF OPERATING SYSTEMS. Operating Systems HOW THE
OPERATING SYSTEM CONTROLS YOUR COMPUTER
Slide 2
1. An Operating System is like gasoline for a car. An operating
system talks between the hardware and the applications. Its the
middle man. Its the gasoline that makes the car go. Without gas, a
car will not run. Computer applications are like the cars air
conditioning, radio, drive, and reverse.
Slide 3
2. What is an Operating System? An operating system is the most
important software that runs on a computer. It manages the
computer's memory, processes, and all of its software and hardware.
An operating system is NOT a single program. An Operating system is
a collection of programs that work together. The operating system
KERNAL is the heart of the operating system that runs all low-level
functions. Device drivers are small software programs that
interface between the operating system and hardware peripherals.
For example: USB drives, printers, and external hard drives. The
operating system talks between the systems hardware and its
applications.
Slide 4
The BOOT PROCESS is a sequence of steps that a computer takes
to go from an empty piece of computer hardware to a computer system
ready to work for the user. 3. BOOT UP PROCESS
Slide 5
PULL YOURSELF UP BY YOUR BOOTSTRAPS MEANING IMPROVE YOUR
SITUATION BY YOUR OWN EFFORTS. ORIGIN THE ORIGIN OF THIS
DESCRIPTIVE PHRASE ISN'T KNOWN. IT REFERS OF COURSE TO BOOTS AND
THEIR STRAPS (LACES) AND TO THE IMAGINED FEAT OF A LIFTING ONESELF
OFF THE GROUND BY PULLING ON ONE'S BOOTSTRAPS. THIS IMPOSSIBLE TASK
IS SUPPOSED TO EXEMPLIFY THE ACHIEVEMENT IN GETTING OUT OF A
DIFFICULT SITUATION BY ONE'S OWN EFFORTS. EARLY COMPUTERS USED A
PROCESS CALLED BOOTSTRAPPING WHICH ALLUDES TO THIS PHRASE THIS
INVOLVED LOADING A SMALL AMOUNT OF CODE WHICH WAS THEN USED TO
PROGRESSIVELY LOAD MORE COMPLEX CODE UNTIL THE MACHINE WAS READY
FOR USE. THIS HAS LED TO USE OF THE TERM 'BOOTING' TO MEAN STARTING
UP A COMPUTER. 4. History of The Boot Process
Slide 6
5. Why an Operating System? Without an Operating System (OS), a
computer is nothing more than a useless collection of electronics.
The operating system makes the computer usable and stable. List at
least four (4) common computer operating systems used today. List
at least two (2) mobile device operating systems. The operating
system manages all resources on the computer or mobile system.
Slide 7
5. The Operating System is contains 3 components : 1. KERNAL: A
program that constitutes the central core of a computer operating
system. It has complete control over everything that occurs in the
system.operating system 2. BIOS: Basic Input/Output System of your
computer, commonly known as the BIOS (pronounced "bye-ose"). On
virtually every computer available, the BIOS makes sure all the
other chips, hard drives, ports and CPU function together. The
primary function of the BIOS is to load and start an operating
system. When the PC starts up, the first job for the BIOS is to
initialize and identify system devices such as the video display
card, keyboard and mouse, hard disk, CD/DVD drive and other
hardware.operating systemvideo display cardhard disk 3. DEVICE
DRIVERS: A device driver or software driver is a computer program
allowing higher-level computer programs to interact with a hardware
devices. (i.e., drivers for printers, digital cameras, USB flash
memory, iPad, iTouch, etc.)computer programhardware

An operating system can be used to manipulate a computers
desktop, files, and drives. Objective: I can use the following
effectively and productively: Windows, folders, files, and
shortcuts.
Slide 12
1. Command vs. GUI Interfaces A command OS interface is simply
text on the screen with only the use of a keyboard. UNIX, DOS, and
original LINUX are command or text-based operating systems. These
operating systems use console commands to manipulate the operating
system. Windows, Mac OSX, and Gnome/KDE LINUX are GUI environments
Graphical User Interface (using a keyboard, mouse and/or icons to
manipulate the operating system)
Slide 13
2. Computer Desktop Environment Desktop GUIs help the user in
easily accessing, configuring and modifying many important and
frequently accessed specific operating system (OS) features. A
desktop environment typically consists of icons, windows, toolbars,
folders, wallpapers and desktop gadgets.
Slide 14
3. Computer Drives A: Floppy disk drives, 3.5" or 5.25", and
possibly other types of disk drives, if present. (*no longer
used)Floppy disk drives B: Reserved for a second floppy drive, if
present. (*no longer used) C: First hard disk drive partition.hard
disk D: to Z: Other disk partitions get labeled here. The letter D:
or E: are often assigned to CD-ROM, DVD drives but not always. In
fact, Windows assigns the next free drive letter to the next drive
it encounters.
Slide 15
4. Computer Folders A folder (or directory) is a container of
documents. Create a new folder by choosing New, Folder Label
folders on a computer just like you would with a real file
cabinet.
Slide 16
5. Computer Files A computer file is a resource for storing
information, which is available to a computer program and is
usually based on some kind of durable storage. computer
programstorage A file is durable in the sense that it remains
available for programs to use after the current program has
finished. Computer files can be considered as the modern
counterpart of paper documents which traditionally are kept in
offices and libraries.documents
Slide 17
6. Shortcuts Ctrl + X is used to CUT Move a File or Folder to a
new drive or folder location Ctrl + C is used to Copy Copy a File
or Folder to a new drive or folder location Ctrl + V is used to
Paste After Cntrl-X or Cntrl-C, then use Cntrl-V to paste the file
in the new drive or folder location Ctrl + Z is used to Undo Use
Cntrl-Z to undo or delete your last operation or action
Slide 18
6. Shortcuts Ctrl + B is used to BOLD Select text, then press
Ctrl + B to Bold Press Insert to change to Typeover Mode which
allows text to be typed on top of the existing text (Typeover
Text), Press Insert again to change back into Insert Mode Ctrl + S
is used to SAVE After a file has been saved with Save As, then use
Ctrl-S often to quickly save changes. Ctrl + A is used to Select
All Use this tool to select all text, picture, files, folders,
etc.

environments.
Slide 24
1. UNIX Operating System The UNIX operating system is widely
used on both servers and workstations.servers workstations The UNIX
environment and the clientserver program model were essential
elements in the development of the Internet and the reshaping of
computing as centered in networks rather than in individual
computers. clientserverInternetnetworks Both UNIX and the C
programming language were developed by AT&T and distributed to
government and academic institutions as "open systems or a FREE
operating system.C programming languageopen systems
Slide 25
2. LINUX Operating System Linux is a free UNIX-type operating
system. Developed under the GNU General Public License, the source
code for Linux is freely available to everyone. Linux operating
system Linux can be installed on a wide variety of computer
hardware, ranging from mobile phones, tablet computers and video
game consoles, to mainframes and supercomputers. Linux is
predominantly known for its use in servers. Most desktop computers
run either Microsoft Windows or Mac OS X. However, desktop use of
Linux has become increasingly popular in recent years. Popular GUI
(Graphical User Interfaces) for PC Linux are Gnome & KDE.
Slide 26
3. Apple OS X Operating System OS X is the tenth major version
of Apple's operating system for Macintosh computers. OS X is based
upon the Mach kernel. One of the major differences between the
previous versions of Mac OS and OS X was the addition of the Aqua
GUI, a graphical user interface with water-like elements. Also,
drop shadows were added around windows and isolated text elements
to provide a sense of depth.
Slide 27
4. Microsoft Windows Operating System Windows is an operating
system produced by Microsoft for use on personal computers,
including home and business desktops, laptops, netbooks, tablet
PCs, and media center PCs. As of April 2013, the most recent

Linux-based operating system designed primarily for touchscreen
mobile devices such as smartphones and tablet computers. Initially
developed by Android, Inc., which Google backed financially and
later bought in 2005. Androids open source code and permissive
