Operating system
Utility programs or tools
an o______ s_____ (OS) is a set of programs containing
instructions that work together to coordinate all the activities among
computer hardware resources.
[NOTES]

C___ b__t is a process of starting a computer or mobile device
from a state when it is powered off completely.
cold boot
W___ b__t is the process of restarting a computer or mobile
device while it remains powered on.

b___ d____e is the drive from which personal computer starts,
which typically is an internal hard drive, such as a hard disk or
SSD.
boot drive
b___ d___ or a r___o___y d__k is a special disk that contains a
few system files that will start the computer.
boot disk or a recovery disk
2 Shut down option modes:
- S___p m___
- H____n__e m___e
Sleep mode
Hibernate mode
shut down option mode where it saves any open documents and running programs or apps to RAM,
turns off all unneeded functions and places the computer in a low-power state
Sleep mode
shut down option mode where it saves any open documents and running programs or apps to an internal an HARD DRIVE before removing power from the computer or device
Hibernate mode
u___ i____f____ (UI) controls how user enter data and instructions and how information is displayed on the screen
[NOTES]
- User interact with software through its user interface.
user interface
2 TYPES OF USER INTERFACE:
- G____c__ U___ I____f____ (GUI)
- C___n_-L___ I_____c_ (CLI)
Graphical User Interface
Command-Line Interface
user interface which interact with menus and visual images by touching, pointing, tapping, or clicking buttons and other
graphical objects to issue commands.
[NOTES]
a GUI designed for touch input
sometimes is called a touch user interface
Graphical User Interface (GUI)
user interface in which user types commands represented
by short keywords or abbreviations or presses special keys to enter
data and instructions. When working with a CLI, the set of commands
used to control actions is called the command language.
Command-Line Interface (CLI)
s_____ t____i__ operating system allows only one program or
app to run at a time.
single tasking
m___t____s___g operating system allows two or more programs or apps to reside in memory at the same time.
[NOTES]
When a computer is
running multiple programs concurrently, one program is in the
foreground and the others are in the background.
multitasking
m___u___r operating system enables two or more users to run
programs simultaneously.
[NOTES]
-Networks, servers, mainframes and supercomputers allow hundreds to
thousands of users to connect at the same time, and thus are multiuser.
multiuser
m____p______g operating system supports two or more
processors running programs at the same time.
[NOTES]
-Involves the coordinated processing of programs by more than one
processor
multiprocessing
M____y M_______t purpose is to optimize the use of a computer or
device’s internal memory. OS allocates, or assigns, data and instructions to an
area of memory while they are being processed.
Memory Management
V____l M____y is used when OS allocates a portion of a storage medium, such as a hard drive or a USB flash drive, to function as additional RAM.
[NOTES]
- The area of the hard drive used for virtual memory is called a swap file because it swaps data, information, and instructions between memory and storage. A page is the amount of data and program instructions that can be swapped at a given time.
- The technique of swapping items between memory and storage, called paging, is a time-consuming process for the computer. When an operating system spends much of its time paging it is said to be thrashing.
