Most systems are open, including ecosystems. In forest ecosystems plants fix energy from light entering the system during photosynthesis.

A thermos flask is the best example of an isolated system. A thermos flask is used to keep things either cold or hot. An isolated system does not exchange energy or matter with its surroundings.

In an isolated system, neither matter nor energy is exchanged with its environment. In a closed system, energy, but not matter, is exchanged. In an open system, both matter and energy are exchanged between the system and its surrounding environment. Any ecosystem is an example of an open system.

Answer: An open system exchanges matter and energy with its surroundings (for example, an ecosystem). Strictly, closed systems do not occur naturally on Earth, but all the global cycles of matter, for example,the water and nitrogen cycles, approximate to closed systems.

Nowadays we make cities to much as a closed system: segregated, regimented, and controlled. Instead of this ‘Closed City’ we need an ‘Open City’ where citizens actively hash out their differences and planners experiment with urban forms that make it easier for residents to cope.

13) associates the concept of the open city with the word “coexistence”, highlighting how a city behaves as an open system when it allows the unprogrammed congregation and encounter of different people and “provides all of its inhabitants access to the concentrated multitude of opportunities they have at their disposal …

Because Android is open source in addition to being an open platform, there’s really nothing Google can do about a proliferation of phones, especially in emerging markets, that ignore its guidelines.

However, more and more of Android comes in the form of closed-source applications and APIs from Google Play Services. “Android” can mean several things. It’s an open-source operating system (AOSP), yes. On the other hand, Apple’s iOS is closed-source.

Humans have a closed circulatory system, which is exactly how it sounds: our blood stays enclosed within blood vessels and the heart.

Google’s Android is considered an Open Source mobile OS, while Apple’s iOS is considered closed source and each has its own benefits and issues. By having an Open Source software program, you allow developers to alter large amounts of the code to their own preference.

Microsoft Windows, a closed-source, operating system, has come under pressure from Linux, an open source one. Similarly, Microsoft Office, a closed- source, office productivity suite, has been under fire from OpenOffice, an open source one (which is the foundation for Sun’s StarOffice).

Open source software is at the heart of Apple platforms and developer tools, and Apple continues to contribute and release significant quantities of open source code.

Closed source software is software that holds the source code safe and encrypted. Meaning, the user can’t copy, modify, or delete parts of the code without some type of consequence. It allows users to copy, modify, or delete parts of the code under their own discretion.

Daemonpenguin: ”Open source is not automatically more secure than closed source. The difference is with open source code you can verify for yourself (or pay someone to verify for you) whether the code is secure. Open source also allows anyone to fix broken code, while closed source can only be fixed by the vendor.

Difference between Open Source Software and Closed Source Software :

List of the Pros of Closed Source Software

• You receive full access to the services you need with closed-source software.
• It allows you to install a large-scale product for research and development.
• There is more usability with closed-source software.
• Closed-source software provides more security to the user.
