This type of license restricts users from accessing the source code of the software and often limits how the software can be used. Users typically receive the compiled program, and they must abide by the terms and conditions set by the software's owner.
What does a type of license that restricts access to source code typically provide to users?
Proprietary (Closed-Source) License: Pros and Cons
Pros
Proprietary licenses ensure that the software owner retains full control over how the software is used.
These licenses often provide additional features, regular updates, and technical support to users.
They protect intellectual property by preventing unauthorized access or modifications to the source code.
Cons
Proprietary licenses restrict user flexibility by not allowing access to the software’s source code.
Users are usually required to pay for the software, which may make it less accessible for some individuals or organizations.
Proprietary license
Open Source License
Open source licenses grant users the right to view, modify, and distribute the source code of the software freely. There are various open source licenses, including the GNU General Public License (GPL), Apache License, and MIT License, each with its own terms and conditions.
What is the primary difference between open source software and proprietary software?
Open Source License: Pros and Cons
Pros
Open source licenses encourage collaboration and innovation by allowing users to view, modify, and distribute the source code.
They promote transparency and community-driven development.
Cons
Open source software may not come with dedicated support or warranties, making it harder for users to resolve issues.
Complying with the terms of certain open source licenses can be complex, especially for businesses.
What is a benefit of open source licenses?
Permissive License
Permissive licenses, such as the MIT License and the Apache License, allow users to modify and distribute the software under relatively lenient terms. Users can incorporate permissively licensed code into their projects, even proprietary ones, without significant restrictions.
Which of the following is an example of a permissive license?
Permissive License: Pros and Cons
Pros
Permissive licenses are highly flexible and allow integration into both open source and proprietary projects.
They impose minimal restrictions, enabling developers to use and distribute the software freely.
Cons
Permissive licenses provide limited protection against misuse, allowing others to use or commercialize derivative works without much restriction.
This can result in the original creator losing some control over their software.
Unlike copyleft licenses, permissive licenses do not place many on users.
Commercial License
Commercial licenses are typically used for proprietary software and require users to purchase a license or pay a fee for specific uses. These licenses often provide additional features, support, or warranties in exchange for payment.
There are different types of commerical licence but they include:
Single user licenses
Multi-user licences
Site licences
Muli-seat licences
Commercial license
Freeware
Freeware licenses allow users to use the software for free, but they may have restrictions on distribution, modification, or commercial use. It also often lacks advanced features, updates, or dedicated technical support.
Freeware is software that is to use and distribute.
Shareware
Shareware licenses often allow users to try the software for free before requiring payment for continued use or access to additional features.
Continued use or access to full features often requires payment after the trial period ends. Shareware versions may also limit functionality compared to the full paid version.
Which type of software license allows users to evaluate the software for a limited period before purchasing?
Public Domain
Software in the public domain is not protected by copyright, allowing anyone to use, modify, and distribute it freely without restrictions. It promotes open access and creativity without any legal limitations.
Public domain software however comes with no support, warranties, or guarantees. The lack of control over derivative works may result in misuse or unintended consequences.
A single-user license
Also known as a single-seat license or individual license, is a software licensing arrangement that grants the right to install and use a software application on a single computer or device, typically for a single user.
In most cases, single-user licenses are non-transferable, meaning the license cannot be shared, resold, or used by multiple individuals on different devices.
Single-user licenses are often associated with software intended for personal or individual use, such as productivity software (e.g., Microsoft Office), creative applications (e.g., Adobe Photoshop), or specialized tools (e.g., accounting software).
Multi-User License
A multi-user license, sometimes referred to as a concurrent license, allows a specified number of users to access and use a software application simultaneously.
The number of users permitted under the license is defined in the agreement, and when that limit is reached, additional users cannot access the software until existing users log out.
Multi User License
Site License
A site license is a software licensing agreement that grants an organization or institution the right to use a particular software product on an unlimited number of computers or for an unrestricted number of users within a single physical location or site.
Site licenses are often employed by educational institutions, government agencies, and large enterprises to provide widespread access to software applications while simplifying management and reducing costs.
Who is most likely to use site licenses?
Multi-Seat License
A multi-seat license, often referred to as a concurrent or shared license, enables multiple users to access and use a software application. However, the number of users who can use the software at the same time is limited to a specified number defined in the licensing agreement.
When the maximum number of concurrent users is reached, any additional users attempting to access the software must wait until an active user logs out or releases their session.
With a , all users at a specific site can access the software.
Educational and Academic Licenses
These licenses are often offered to educational institutions, students, or researchers, allowing them to use the software for educational or research purposes under specific terms and conditions.
Educational software licenses often grant users the to use the software for educational purposes.
