Systems Essentials questions with answers |\ |\ |\ |\
operating system |\
system software that acts as a "go-between", allowing computer
|\ |\ |\ |\ |\ |\ |\ |\ |\
hardware and other software to communicate with each other
|\ |\ |\ |\ |\ |\ |\ |\
What is the purpose of a computer operating system?
|\ |\ |\ |\ |\ |\ |\ |\
It functions as a resource manager.
|\ |\ |\ |\ |\
Which kind of software are Mac OS X and Windows 10 programs?
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Operating system (OS) |\ |\
Which operating system allows for its source code to be modified
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
and redistributed?
|\ |\
Android is an open-source mobile operating system; therefore,
|\ |\ |\ |\ |\ |\ |\ |\
source code is available, and anyone can modify and redistribute
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
it.
Cloud-based operating systems |\ |\
primarily manages the operation of one or more virtual machines
|\ |\ |\ |\ |\ |\ |\ |\ |\
within a virtualized environment.
|\ |\ |\ |\
What is a feature of cloud-based operating systems?
|\ |\ |\ |\ |\ |\ |\
They are primarily stateless.
|\ |\ |\
System calls |\
unique set of services provided by operating systems for use by
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
applications and have to be accounted for by different operating |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
systems.
Application Programming Interface (API) |\ |\ |\
,A set of software routines that allows one software system to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
work with another. |\ |\
Why do applications designed to work on one operating system
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
not work on a different operating system?
|\ |\ |\ |\ |\ |\
Unique system calls |\ |\
single‐user systems |\
multitasking systems, found in laptops and workstations |\ |\ |\ |\ |\ |\
mobile device operating systems |\ |\ |\
provides single-user and multitasking at a scaled-down level due
|\ |\ |\ |\ |\ |\ |\ |\ |\
to power and memory limitations
|\ |\ |\ |\
Basic resources OS organizes before users can give a computer
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
instructions:
1. Processor
|\
2. Storage
|\
3. Devices
|\
4. Input/Output
|\
5.Memory
Mainframe Systems |\
large, fast, and powerful, used for high transaction processing
|\ |\ |\ |\ |\ |\ |\ |\ |\
and complex computations; used by corporations and
|\ |\ |\ |\ |\ |\ |\
government agencies |\
network server systems |\ |\
designed and named for a specific purpose such as database
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
servers, web servers, and print servers |\ |\ |\ |\ |\
real‐time systems |\
designed to direct CPU access immediately when needed or
|\ |\ |\ |\ |\ |\ |\ |\ |\
required
Embedded control systems |\ |\
, specialized operating systems designed to control a single piece
|\ |\ |\ |\ |\ |\ |\ |\ |\
of equipment or machinery
|\ |\ |\
distributed systems |\
geared toward allocating process power, programs, files, and
|\ |\ |\ |\ |\ |\ |\ |\
databases to network users |\ |\ |\
Application Software |\
software program that helps you use the computer to do
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
particular tasks |\
Drivers
instructs a particular OS on how to access a piece of hardware
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
version
particular revision of a piece of software, normally described by a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
number that tells you how new the product is in relation to other
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
versions of the product
|\ |\ |\ |\
source code |\
actual code that defines how a piece of software works
|\ |\ |\ |\ |\ |\ |\ |\ |\
Open Source |\
Software that is created for free use by everyone
|\ |\ |\ |\ |\ |\ |\ |\
closed source |\
source code that is highly protected and only available to trusted
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
employees and carefully vetted contractors
|\ |\ |\ |\ |\
Graphical User Interface (GUI) |\ |\ |\
A visual display on a computer's screen that allows you to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
interact with your computer more easily by clicking graphical
|\ |\ |\ |\ |\ |\ |\ |\ |\
elements.
network
a group of two or more computer systems linked together
