What is an Operating System (OS) - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\
✔✔Operating systems and their collective features enable the |\ |\ |\ |\ |\ |\ |\ |\
computer's hardware devices and application software to work |\ |\ |\ |\ |\ |\ |\ |\
together. It organizes and manages the major function of the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
computer, such as I/O, processing, storage, and memory. These
|\ |\ |\ |\ |\ |\ |\ |\ |\
OS are considered proprietary system software, each with its own
|\ |\ |\ |\ |\ |\ |\ |\ |\
customized features such as graphical user interfaces (GUIs), 32
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
bit/64 bit OS and RAM (Random Access Memory).
|\ |\ |\ |\ |\ |\ |\
What are the categories of OS? - CORRECT ANSWERS ✔✔Single
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
user systems
|\
Single-User, multitasking systems |\ |\
Mobile device OS |\ |\
Mainframe systems |\
Network server systems |\ |\
Embedded control |\
Distributed systems |\
Real-Time systems. |\
Single user systems - CORRECT ANSWERS ✔✔are considered
|\ |\ |\ |\ |\ |\ |\ |\
multitasking systems, they are found in laptops and workstations. |\ |\ |\ |\ |\ |\ |\ |\
,Mobile device OS - CORRECT ANSWERS ✔✔are for small handheld
|\ |\ |\ |\ |\ |\ |\ |\ |\
devices such as e readers, phones, and tables, these can provide
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
single user systems and multitasking at a scaled down level due
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
to power and memory.
|\ |\ |\
Mainframe systems - CORRECT ANSWERS ✔✔manage large scale |\ |\ |\ |\ |\ |\ |\ |\
platforms and enterprise environments that require large
|\ |\ |\ |\ |\ |\ |\
amounts of storage, memory, and computing. |\ |\ |\ |\ |\
Network server systems - CORRECT ANSWERS ✔✔designed and
|\ |\ |\ |\ |\ |\ |\ |\
named for a specific purpose such as database servers, web
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
servers and print servers. |\ |\ |\
Embedded control systems - CORRECT ANSWERS ✔✔specialized |\ |\ |\ |\ |\ |\ |\
OS designed to control a single piece of equipment or machinery.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Distributed systems - CORRECT ANSWERS ✔✔geared toward |\ |\ |\ |\ |\ |\ |\
allocating processing power, programs, files, and database to
|\ |\ |\ |\ |\ |\ |\ |\
network users. |\
Real-Time systems - CORRECT ANSWERS ✔✔Used for |\ |\ |\ |\ |\ |\ |\
instrumentation where system responses are time sensitive. |\ |\ |\ |\ |\ |\
What is source code? - CORRECT ANSWERS ✔✔Is the actual code
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
that defines how a piece of software works. It can be open source
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
or closed source (meaning only that the owner/developer can
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
modify or examine the code)|\ |\ |\ |\
,What is a shell? - CORRECT ANSWERS ✔✔A program that runs on
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
top of the OS and allows the user to issue command through a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
set of menus or another interface.
|\ |\ |\ |\ |\
What is cooperative multitasking? - CORRECT ANSWERS ✔✔It's a
|\ |\ |\ |\ |\ |\ |\ |\ |\
method that depends on the application itself to be responsible
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
for using the processor and then freeing it for access by other
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
applications.
What is preemptive multitasking? - CORRECT ANSWERS ✔✔It's a
|\ |\ |\ |\ |\ |\ |\ |\ |\
multitasking method in which the OS allots each application a |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
certain amount of processor time and then forcibly takes back
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
control and give application or task the access to the processor.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
What is multithreading? - CORRECT ANSWERS ✔✔is the ability of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
a single application to have multiple requests into the processor
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
at one time. This results in faster application performance
|\ |\ |\ |\ |\ |\ |\ |\ |\
because it allows a program to do many things at once.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
What is ARM? - CORRECT ANSWERS ✔✔It's an OS that uses a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
reduced instruction set computing (RISC) instruction commonly
|\ |\ |\ |\ |\ |\ |\
found in tables and phones processors. ARM-v8 can support and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
64-bit processor. |\
What is the File Management system and what does it do? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔Allocates and manages the secondary |\ |\ |\ |\ |\ |\ |\
storage space and translates file requests from their name-based
|\ |\ |\ |\ |\ |\ |\ |\
from into I/O request.

What are the 4 operating system categories? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔server, |\
workstation, mobile, or cloud-based operating systems. |\ |\ |\ |\ |\
Server operating systems - CORRECT ANSWERS ✔✔allow for the
|\ |\ |\ |\ |\ |\ |\ |\ |\
sharing of information and applications by workstation operating
|\ |\ |\ |\ |\ |\ |\ |\
systems. The operating system is optimized for background
|\ |\ |\ |\ |\ |\ |\ |\
processes used for access by clients, as opposed to the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
foreground processes, such as the GUI. |\ |\ |\ |\ |\
Workstation - CORRECT ANSWERS ✔✔operating systems allow |\ |\ |\ |\ |\ |\ |\
end users to access information and applications on server
|\ |\ |\ |\ |\ |\ |\ |\ |\
operating systems as well as independently run applications
|\ |\ |\ |\ |\ |\ |\ |\
locally. The operating system is optimized for foreground
|\ |\ |\ |\ |\ |\ |\ |\
processes, such as the GUI. Background sharing is usually limited
|\ |\ |\ |\ |\ |\ |\ |\ |\
to a specific number of users; workstation versions of Microsoft
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Windows are limited to 10 concurrent users.
|\ |\ |\ |\ |\ |\
Mobile operating - CORRECT ANSWERS ✔✔systems are found on
|\ |\ |\ |\ |\ |\ |\ |\ |\
mobile devices such as phones and tablets. The mobile operating
|\ |\ |\ |\ |\ |\ |\ |\ |\
system is generally optimized for touch-based devices where one
|\ |\ |\ |\ |\ |\ |\ |\ |\
program is used at a time.
|\ |\ |\ |\ |\ |\
Cloud-Based - CORRECT ANSWERS ✔✔operating systems are a |\ |\ |\ |\ |\ |\ |\ |\
new breed of operating system that has emerged from the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
mobile computing era. Cloud-based operating systems are also
|\ |\ |\ |\ |\ |\ |\ |\
considered stateless operating systems since personal data is not
|\ |\ |\ |\ |\ |\ |\ |\
primarily stored on the device but in the cloud. Mobile operating
