📚 Introduction to Software Types: Freeware, Free Software, and Shareware
The lecture begins with a refresher on the definitions of freeware, free software, and shareware. Freeware is defined as software distributed without a fee, available as fully functional with no time limit, exemplified by Skype and Adobe Acrobat Reader. However, freeware is proprietary, meaning redistribution is not allowed. Free software, in contrast, emphasizes the freedom to run, copy, distribute, study, change, and improve the software, with the availability of source code being a key difference. The concept of 'free' in free software refers to liberty, not necessarily price, and is governed by copyleft licenses. Shareware is described as proprietary software with a trial period, allowing users to use the full version for a limited time before requiring a license to continue use.
🔍 Main Differences Between Freeware, Free Software, and Shareware
This paragraph delves into the distinctions between freeware, free software, and shareware. Freeware, while free to use, is proprietary and does not allow modification or redistribution. Free software offers the freedom to modify and distribute without limitations, with the availability of source code being a fundamental aspect. Shareware is characterized by a trial period, after which a license must be purchased to continue using the software. It is not considered free software as it requires payment after the trial, and users do not have the freedom to modify the software. The paragraph clarifies that shareware is not open-source software, which allows for free modification and use without a license.
📝 Summary of Key Differences and Examples
The paragraph provides a summary of the differences between the software types, focusing on cost, payment models, source code access, and user freedoms. Freeware and free software are initially free to use, but free software offers the additional freedom to modify the software. Shareware is free for a trial period but requires a license for continued use. Examples are given for each type: Acrobat Reader and Skype as freeware, Linux and GNU Emacs as examples of free software, and WinRAR and WinZip as shareware. The paragraph concludes with a reiteration of the key differences, emphasizing the importance of the four freedoms in defining free software.
📖 Assignment: Essay on Advantages and Disadvantages of Software Types
The lecture concludes with an assignment for students to write a two-page essay discussing the advantages and disadvantages of freeware, free software, and shareware. Students are encouraged to think critically about these software types without additional research, based on their understanding from previous lessons. The essay should include a conclusion that addresses which type of software the student believes is better, with the understanding that there is no absolute answer to this question. The assignment is due by the following Friday, with specific formatting instructions provided, including A4 paper size, 1.5 line spacing, a font size of 10, and justified margins.

Transcripts
all right so for lecture 7 we are going
to have comparison between three types
of softwares namely freeware free
software and shareware so all of this we
have already defined before s various
lessons so let's just have a
refresher freeware free software and
shareware okay so first freeware so
according to the definition freeware is
software that is distributed without
demanding a fee for its usage these
programs are available either as fully
functional software for an unlimited
period
[Music]
okay and at the same time fully featured
okay meaning restrictions when it comes
to the
features example is Skype okay Adobe
Acrobat Reader okay again emphasis Adobe
Acrobat
Reader open
PDF okay so the only difference is
that freear just like how we defined it
before distribute okay well
technically
sir
fre isn't that redistribution in itself
when we talk about
redistribution
the
okaya quote and quote reselling so we
are not allowed to redistribute
freewares
okay because basically freewares are
proprietary
software okay so free in a sense that
there is no cost for us to use it
okay so the developer can change future
releases from freear to a paid product
if he wishes to do so so
distrib sofware
then okay so
typically source code so meaning the
difference between a freeware and a free
software is that available source code
so therefore
modify okay and at the same time
because modified version
software okay so that is freeware
basically a proprietary
software Li
okay Unlimited
it's just
thaty
software source code
okay software is developer or
organization software so that is
freeware free
software so free
software software wherein my freedom
to run copy distribute study change and
improve the software okay so in
short free
software it's a matter of Liberty
meaning
Freedom not necessarily the price itself
okay so present Four
Freedoms however want to use
ity because
available source code distribute the
program stipulated to one condition any
redistributed version of the software
must be distributed with the original
terms of free use modification and
distribution so copy left licenses okay
so unlike freeware free software
distribute for a fee
okay with a fee it is according to a
certain license okay so depend a
license distribute copy free software
for free okay per
overall free software should be
available for us to use freely My
Liberty to use okay not necessarily the
price itself so an main difference again
main difference between freeware and
free software you number one is
that free
software downlo modify and distribute
free software without any limitations
okay versus a free
okay since at the end of the day
freeware is still proprietary software
official software versus free software
where download modify distribute and at
the same time free
software modify okay simply because
available source code software so
eny and at the same
time modified copy
software
okay so that's the main difference
between freeware and free
software so next
shareware shareware so shareware simply
this is a proprietary software
trial
period
isal software wherein for a certain
period of
time 15 to 30 days per common is one
weekare full
version
okay quote andot software before
deciding if you want to buy a license to
continue using that
software
okay so after the evaluation period the
program expires and users can no longer
access the program so after
period
sofware license in order for us to
continue using the program okay
softare
MPS one we trial
period okay
so shareware is lightwear l i t e w a r
e
lightwear so meaning light versions
software wherein for a period of time
yes shareware without any license sense
however there are times wherein May
certain features not
prohibited okay certain features not
prohibited access once you buy a license
to fully use the program okay so that is
shareware shareware equals trial period
wherein after the after the
trial full version
no software okay so questions okay
questions is shareware a free software
the answer is
no free software yes certain
license software however when we are
talking about free software generally we
can use it at no extra cost for as long
as you want okay meaning well may
Liberty to use
it anytime any place
anywhere okay and at the same time free
software modify on the other hand yes
share wear Li for a certain period of
time however
after perod
of okay and at the same time free
software IM modify while shareware which
is still shareware is still a
proprietary software therefore we cannot
modify that software and at the same
timey Source C
sofware okay so that is the difference
between a shareware and a free software
so there for shareware is not a free
software because as people in the IT
industry because it
will meaning for a certain period of
time
yes however
afterwards okay so shareware is not a
free
software okay
so free software always remember the
Four Freedoms for us to even consider it
as a free
software
okay next is shareware and open-source
software the answer is also no okay
because open source software can be
downloaded and modified for free okay
my free when it comes to Liberty wherein
we have the freedom to use it any way we
want it without uh paying for a license
and at the same time P open source
software
available source
code okay available Source Cod on the
other hand users need to purchase a
shareware after a certain amount of time
when the trial period expires
of for free
afterwards license for us to be able to
use the shareware continuously so in
simple terms shareware is not an
opsource
software
okay
so summary
differences okay when it comes to the
cost
yes free freeware free
software shareware free for a certain
period of time
okay
ex license okay source code access
available source code is free software
okay free software
L for us to be able to modify or rather
modification rights free
software
meaning
software redistribution
rights distribute is free software
however shareware
technically during the trial
period for a certain period of
time software for free
afterwards
licare so
examples Acrobat Reader again reader
freew full version Adobe
Acrobat convert PDF files edit PDF files
so on and so forth Acrobat reader PDF
reader purely so it is a freeware Skype
is also an example of freeware free
software Linux gnu emac so open source
software then
shareware example is wiar windzip okay
so trial version afterwards promp promp
hey you need to buy a license for us for
you to continue using our
software okay
so the key differences T is first cost
and payment model so again freeware and
free software are free to use however
free software may offer freedom for us
to also modify the software shareware
free initially
afterwards okay source code availability
free software
Liberty for us to modify you source code
okay while you free soft free Weare and
sharew and lastly user freedoms free
software emphasizes user freedoms
meaning freedoms for us to use to study
to modify and to
distribute while freeware and shareware
emphasize free or trial use but restrict
other freedoms
