Copyright Copyright is personal property. It can be bought and sold like any other property — a house, a car, a pen. Cars and pens are choses in possession, or chattels. Example As you know, copyright protects source code. It also protects the written word in books.
In this context, that means: copy the book; authorise others to copy the book. Source code is protected in the precisely the same way as books. Like all intellectual property rights, copyright vests in the work itself to protect it. You've probably heard some of those terms in the context of copyright, or similar terms. Licenses A licence is a grant of a permission. Some people classify the Public Domain as free software, but this is erroneous, since this category is highly dependent on the laws of the country in which the program is used or was written.
In addition, such programs retain the old licensing agreements, which do not say that the program can be used freely, so if you check it, there may be trouble. Commercial software commercial software - Initially created for commercial purposes, usually by selling copies.
Hostageware - Has time limits, or the number of licenses that can be unlocked after payment. Trialware, Trial, Demoware - Demo version of a commercial software product that has time or functionality limitations. Beerware - Allows the user to use the program and source code for free, but if he meets the author, he must buy him a glass of beer.
Betaware - Beta version, for the testing period may be allowed to use free of charge. Freeware - Can be used free of charge subject to the terms of the license agreement, which in most cases is explicitly prohibited from use in the organization.
Postcardware, Cardware - Can be used for free, but the author asks to send him a postcard. Proprietary software Proprietary software - Proprietary, subject to license agreement. For the user, the free software is the same, because all of them are allowed to be used both at home and in the office. Free software - General term for free software. But due to the ambiguity of the word Free, it is confused with free software, so it was recommended to move to the term Open source software.
Permitted to use, redistribute and modify. When modifying the program, you must further distribute the product under the same license. BSD - Usually there are only three points in such a license. A software license is a contract between the entity that created and supplied an application, underlying source code, or related product and its end user. The license is a text document designed to protect the intellectual property of the software developer and to limit any claims against them that may arise from its use.
A software license also provides legally binding definitions for the distribution and use of the software. Most software falls under one of two categories that have distinct differences in how they are viewed under copyright law:.
FOSS software licenses — give rights to the customer that include modification and reuse of the software code, providing the actual source code with the software product s. This open-source type of licensing affords the user authority to modify the software functions and freedom to inspect the software code.
Proprietary software licenses — provide no such authority for code modification or reuse and normally provide software with operational code only, and no source code. In both cases, the software license will most often specify limitations of liability from use of the software product, any mutual responsibilities such as support, and any warranties or disclaimer of warranty. Open source and proprietary software licensing may also specify additional restrictions and terms:. New users of a software will normally enter into an end-user license agreement EULA that constitutes a legal definition of the relationship between the licensor provider and licensee user or business.
The EULA is a contract that establishes the rights of the purchaser for installing and using the software. Every EULA contains a clause that stipulates when its conditions are activated by an end user. The developer retains ownership, but the re-branding company is permitted to resell the software product.
There are five main software license categories or types used to cover different kinds of software and various business arrangements. These encompass a wide spectrum of licensing scenarios, from free software public domain to paid commercial software proprietary. When software is defined as being in the public domain, anyone is free to use and modify the software without restrictions.
For many reasons, businesses must exercise caution when adopting public domain software in projects or other important applications:.
