An Open System is a computing platform that uses Open Source softwares rather than Closed Source/Proprietary softwares.
Closed source software may charge for their software, but might not.
If a development firm releases software for free, but does not release the source code to the public, this is called "Freeware."
Proprietary software generally does not distribute their software for free, and it follows that the owners do not distribute the source code either.
An few examples of proprietary software are Microsoft Windows (Operating system), Microsoft Office (Office Software Suite), Nero (CD/DVD Burning Software), and WinRAR (Archiving Tool).
The point of an Open System is to break away from the use of software that you have to pay for. Some people also go a step further and refuse to use software that the owners do not release the source code of.
This principle is especially useful in business, where a company can save a lot of money making their employees use Free and Open Source software rather than paying licensing fees to use one product on multiple machines.
A few examples of Free and Open Source softwares that do the same job as the Proprietary softwares cites above are:
Debian Linux (Operating System), Open Office (Office Software Suite), K3b (CD/DVD Buring Software), PeaZip (Archiving Tool).
The human brain and nervous system is the ultimate example of a computer system. It has input devices (eyes, ears, touch, taste, smell), output devices (expressions, actions and emotions) and processors (the brain itself).
All computers have the ability to compute -- that is their common trait; to perform a computation. However in order to compute there has to be something to be computed (an input) and a result of that computation (an output). Thus all computers can be characterised as a device that combines input, processing and output devices.
Some specific examples:
Computers and processors are ubiquitous in everyday life, and they're not only found in your PC. This unit introduces the different parts of computer systems and their use of binary code. Using the examples of kitchen scales, a digital camera and a computer artwork the unit, with the help of flowcharts, discusses how computers process data and instructions .

grasshoppers, have an open circulatory system
The system without feedback is known as open loop system. The examples of the open loop system are bread toaster, oven ,washing machine. The open loop systems are inaccurate & less complex.
An Open System is able to be changed by the userA Closed System cannot be changed by the person using the computerExamples of Open Systems include Linux, examples of closed systems include Macintosh OS X
There are several open-source operating systems, most of which appear to be clones of Unix. Examples include FreeBSD, Linux, Minix.

Examples of organisms with open circulatory systems include arthropods, such as insects, spiders, and crustaceans. In these organisms, the circulatory system does not contain blood vessels; instead, the blood is pumped from the heart into body cavities where it directly bathes the tissues before returning to the heart.
Open source software is software that you are legally entitled to copy, reinstall, modify, and redistribute and is usually free to download from the software's website. the ubuntu operating system, open office.org, and opensuse Linux are a few examples of open source software
Closed circulatory systems have blood that does not flow in defined blood vessels. Examples are insects and how their organs are bathed continually in "blood". Open circulatory systems have blood that flows in vessels. Humans have this system as blood flows in veins, arteries and capillaries.
