A computer required hardware to perform its function. And the hardware need software to make it run. Without software, hardware would be useless and without hardware, software can not be used. Brain is like the hardware and mind is like the software. But in reality, the difference between brain mind are more complicated than software and hardware.
In our culture we sometimes use the words brain and mind interchangeably even though they really do refer to separate, although often overlapping, concepts. The brain is an organ but the mind isn't. The brain is the physical place where the mind resides. It is a vessel in which the electronic impulses that create thought are contained. With the brain you coordinate your moves, your organism, your activities and transmit impulses. But you use the mind to think. You can muse at what happened, what is scheduled and what maybe will happen.
The mind is the manifestations of thought, perception, emotion, determination, memory and imagination that takes place within the brain. Mind is often used to refer especially to the thought processes of reason. The mind is the awareness of consciousness we know, the ability to control what we do, and know what we are doing and why. It is the ability to understand. Animal are able to interpret their environments, but not understand them. whereas human are able to understand what happens around them, even if not the scientific reasoning for it, and therefore adapt.
The mind made humans capable to solve complex logical problem which differentiates us than other living beings. Logic makes us understand that things are not as what they seem. Our ability to analyze situations makes it possible to develop solutions to problems and lead us toward practical solutions. We may not be able to see in the ultraviolet range, but we may design instruments to do so. We may not be able to see atoms, but we can design experiments that enable us to know their properties. Each stage of scientific advancement has usually been made by trying to reach a logical conclusion consistent with our observations. We no longer believe in demons as the cause of disease. We now believe in viruses, bacteria, genetic defects, and environmental pollution as the real causes of disease. Our irrational and unfounded "superstitions" have given way to "knowledge".
