One of the jobs of the kernel is to:
Turn source code into machine code
Transfer mail from one machine to another
Manage the system’s resources
Load the operating system after the computer is turned on
Unix is:
A distribution of Linux
a trademark
A text editor
An operating system
A type of hardware
Linux is written in:
C
.NET
Java
Perl
C++
Source code refers to:
The interface that software uses to talk to the kernel
The license that dictates how you may use and share the software
The version of a program that the computer runs on the CPU
A human readable version of computer software
Open source means:
You must support the software you share
You can view the software’s source code
You cannot charge anything for the software
You must share your changes
You can modify the software’s source code
Most of the tools that are part of Linux systems come from:
Google
Red Hat and Debian
The Open Source Initiative
The Linux foundation
The GNU project
The Linux platform that runs on mobile phones is called:
Android
Teldroid
LinuxMobile
IOS
MicroLinux
What does a distribution provide to add and remove software from the system?
Bash
Application Programming Interface (API)
Partitioning tool
Package manager
Compiler
The bootloader’s job is to:
Load the application into memory
Assign initial settings such as network address
Install software from the Internet or removable media
Perform the initial installation of the kernel to hard drive
Load the kernel after the computer is powered on
UNIX was originally invented at:
Stanford University
AT&T Bell Labs
Berkeley University
Xerox PARC
Bangalore University
A license where you don’t have access to the source code is called:
Impaired source
Closed source
Open source
Sourceless
Which distributions are made by, or clones of, Red Hat?
Fedora
Ubuntu
Slackware
Debian
CentOS
Ubuntu is derived from which distribution?
Scientific Linux
Red Hat Enterprise Linux
Open source licenses differ, but generally agree that:
You must redistribute your changes
You are not allowed to sell the software
You should be able modify the software as you wish
You should have access to the source code of software
Applications make requests to the kernel and receive resources, such as memory, CPU, and disk in return.
The most important consideration when choosing an operating system is:
What the computer will do
The licensing model of the operating system
The operating system’s mascot
How much performance is needed
Whether or not it is cloud-friendly
Linux is not Unix because:
It’s not good enough
It’s free
It’s not made by the Open Group
There are too many distributions
It hasn’t undergone certification
A release cycle:
Is always 6 months
Doesn’t matter in an Open Source environment
Describes how long the software will be supported for
Describes how often updates to the software come out
Only applies to software you pay for
A maintenance cycle:
Only has meaning for paid software
Should be long so that you have time before you need to upgrade
Should be short so you always have the freshest releases
Describes how often updates for software come out
Describes how long a version of software will be supported
If a software release is in a state in that it has many new features that have not been rigorously tested, it is typically referred to as beta software.
Apple’s OS X is:
Derived from Linux
Only compatible with Apple hardware
Primarily used to manage network services
Certified as UNIX compatible
Derived from FreeBSD
Able to natively run Windows binaries
Microsoft Windows:
Has a new desktop version every year.
Has a short maintenance cycle
Comes in desktop and server variants
Has built in virtualization
Has a Linux compatibility mode
Has powerful scripting capabilities
Other commercial Unixes:
Are tied to their vendor’s hardware
Do not run the GNU tools
Are UNIX certified
Are almost obsolete
Use completely different commands than Linux
When choosing a distribution of Linux, you should consider:
Which management tools are provided by the distribution
Whether or not the distribution is under active development
The maintenance cycle of the distribution
Popularity on social media.
If you need support on the distribution itself
Which distributions are supported by the software you need to run
