matter how many programs may be, all we can distinguish between two types: free and paid.For those who are interested to know more about licenses - will be useful to read this article.
presence of various licenses assumes different responsibilities manufacturer to the end customer.And the presence of maintenance of computers, if it is assumed will depend on the license.In addition, the license stipulates the conditions of use of the program.Under certain circumstances, it can be both paid and free.Almost like Schrödinger's cat.
What is a license?
De facto - the license terms of this program, in which the authors enable you to use the results of their work.License is provided with almost all of the programs.Often, with its text You can see directly during installation.At one point you will be offered to read her text and tick "I agree."From a legal point of view, while agreeing to the license, you take the license obligations of owning a product.Even if it's free, you become the owner of a licensed copy of the program.
Under the terms of the license of use of the program are divided into three categories: freeware, shareware and commercial.In fact, it is somewhat more complicated, but first we take this as a major division.Each category has its own variety of licenses.We analyze the main.
Freeware license
Free .These programs are distributed for the best price - free.You will not be asked to pay a month and do not limit functionality, advertising the paid version.On the other hand, you consent to the exclusive rights of the author of the program on its code.
Free for home use .This means that if you use the program for non-commercial purposes, to pay for it is not necessary.The company installed a program can only be received for the money extended license.
Public domain - Public License.It has no author.Sort of a child of postmodernism.
Opensource (and GNU - General Public License ) .Roughly speaking, what is and is enclosed in brackets are not the same, but just going to think otherwise.The essence of this license is that if you want you can not only enjoy it, but even to make their own changes to the code.However, provided that you change the license.
They were free programs that do not have any restrictions, and not "extort" money.Below we look at other kinds of free programs that are likely to have advertising goals.
Advertising-free license
Donate - most "gentle" way: Do you use the full version, but the author periodically reminds that if you all like it, you can support it financially.
AdWare - -old form of "free" software: you are not deprived of the functions of the program, but show advertisements in the program (if the pop-up during start-up or during operation, then we Nagware or begware ).Program earns just for the money, which the author received from the sale of advertising.
Registerware - to use the program, the license required to register on the site.Thus the author gets the statistics and your mailing address to send him advertising messages.
Shareware license
«Bloomers» - this is a shareware program.You are invited to view the complete (in the case of full trialware or truncated when shareware , although this distinction is suspended) version of the program for a limited time (the number of launches or days) and make a decision about the purchase.Often, one of the limitations to the free version of a paid service available computer.
Demo - demo version.Functional went under the knife, sometimes a part of the basic functions, such as preservation.
Paid license
P ayware - only for the money.Such programs often have the versions that are distributed under licenses that we have reviewed in the section shareware.This is usually "box" that we buy in the store.
That's the whole list of the most common licenses.
