For many years now, we have seen how computers are challenging the abilities of the human brain and becoming more and more advance, but the human brain has been accountable for the thought, creativity, feelings, and other qualities that make us humans. Besides, everything that is found in a computer is based on what the human brain has acquired through experience.  

  The human brain 

Indeed, our brains are amazing, a body controller, calculator and a powerful memory packed into a small or little space. Many techniques has been developed by scientists to study what is going on in the brain of human as we think or move but unfortunately, few of the discernments they have made so far have lead to any developments in standard clinical mental care. The brains work through a spectacular confection of electrical signals and chemical impulses. Neurons are the cells in the brain that convey information about the world around us, help us make sense of the world, and send commands to our muscles. In our brains, there are over 86 billion neurons. But unlike the common saying, we hardly use 10% of it. For Sure, a computer uniquely programmed to perform some tasks which can give human a run for their money, but when we measure a computer against the entirety of what a human mind is capable of, it is not really all that close. The human brain is far more efficient and advanced and it possesses more raw computational power than the most impressive computers that have ever been built.

Humans are more powerful than computers at tasks that are difficult and not broken into simple step. The brain is not a storage dump, and consciousness is not a place. Our brains are capable of analyzing unfamiliar and new situations in a way that computers can't. The brain is more complex and more complete than any computer. Our brains aren't digital. Maybe things like those gradually contrast levels do matter for the things we are interested in knowing, like gleams of inspiration. For as powerful and swift computers have become, they still stand no match with the human brain. Synapses are also far more complex than electrical circuits. The brain is not a computer in the literal sense of the word, but the brain as a computer is a powerful one.

The computer 

Computers are man-made machines and they have been designed to perform repetitive functions. Computers are rapidly improving at the pattern. So, computers are faster than humans when talking about carrying out simple instructions step-by-step. It is undeniable that the computer is becoming more intelligent as technology develops with each passing day. The ability of computers to withstand temperature extremes, mechanical shocks, humidity, chemical spills, magnetic fields, and other environmental effects is of utmost importance. So it shows our brains are not very much comparable to computers at all. Computers operate in a different way, they cannot adjust as our brains can and they cannot self-repair. Like a lot of people would say that computer lack consciousness, free will, and minds.

Computer system contributed immensely to the development of the world as a whole by making work easier and simple for a human being. The fields of artificial intelligence, computer science, and machine learning are targeted at breaking down difficulties into “byte-sized” chunks which are “digestible” by the computer. The computer is faster at doing logical things. Computers mimic all of the ways that humans gain information. The computer can do many complex tasks at the same time that are difficult for the brain and perform complex actions.

There is some similarities and difference between the brain when is compared to a computer. Some people use this comparison to say that the computer is better than the brain while some people say that the comparison shows that the brain is better than the computer. Perhaps, it is best to say that the brain is better at doing some jobs and the computer is better at doing other jobs. Let's see how the brain and the computer are similar and different from each other.

Differences between the brain and computer

There are many differences between the computer and the human brain. The brain is far more complex than any computer with estimates at 225 million billion interactions between cell types, neurotransmitters, neuromodulators, axonal branches and dendritic spines. Also, computers are limited to what they “learn”, depending on the memory left or space on the hard disk not like the human brain which is constantly learning every day. The programs that run on computers are editable, copyable and predictable. The computers are designed, build and are of fixed architecture, the brain is a self-organizing system. Computers can be programmed to learn new things whereas brains learn by experiencing themselves, and are capable of reprogramming themselves. And also the brain uses chemicals to transmit information; the computer uses electricity.

Similarities between the brain and computer

There are some real similarities between the human brain and computer. First, both are separated into many sections, each with its own functions. The human brain has areas for sight, sound, smell, etc. The computer brain has areas for recognition, comparison, arithmetic, etc. Both the brain and computer are used to store information, process the information and run the tasks. Both also play extremely important roles in society, commerce, entertainment, and science. They both have the ability to retain memories of all kinds of things. Just like machines, computers break down with time. Brain cells deteriorate with age, losing their functions and slowing down because of lower counts of chemicals and hormones in the body.


The human brain is constant and the ability has not changed anytime, only the Great knowledge of man can easily changed, so this knowledge is invested in the computer. Next time when you sit down with your computer and think about how wonderful it is, also pause and think about how amazing our own brain is. Have it in mind, there would be no computer without the human brain in the first place.
