Computers have certain primary purposes: Entering data, manipulating data, viewing processed data and storing data. They are designed to transform raw data into information. The computer operates under the control of instructions stored in its own memory unit and can accept input data, process it arithmetically and through sequenced based logic, produce information and store the results for future use.

Many times, the human brain presents similar functions to a computer since, both are used for storage, processing information and execute tasks. Both work with electrical signals in computer mediante use the binary system and the human brain through neuron to neuron. Both the brain and the computer use electricity to send signals. As it concerns the memory, computers can continue to store memories as they add more RAM and stores them in a more orderly way than the human brain.

However, computers can only follow instructions and patterns made by a programmer, while the brain behaves freely, using reasoning and common sense. Also, the brain can’t act without emotions while computers only act under the logic. Moreover, the human brain can easily adapt to new circumstances and learn faster. The same calculations and processes that might take a computer a few millions steps can be achieved by a few hundred neuron transmissions, requiring far less energy and performing at a far greater efficiency. The amount of energy required to power computations by the world’s fastest supercomputer would be enough to power a building; the human brain achieves the same processing speeds requiring energy to charge a dim lightbulb.

One of the things that truly sets brains apart, aside from their clear advantage in raw computing power, is the flexibility that it displays. ?he human brain has the ability to rewire itself (neuroplasticity). Neurons are able to disconnect and reconnect with others, and even change their basic features, something that even a carefully constructed computer can’t do. Apart from that, when we say computers, we are referring to meticulously designed machines that are based on logic, reproducibility, predictability, and math. The human brain, on the other hand, is a tangled and random mess of neurons that don’t behave in a predictable manner.

The fastest supercomputers, which are massive, created thus far haven’t even reached the 50 pet FLOP mark, which is still 20 times slower than the human brain’s processing speed! Looking towards the future, experts believe that only exascale computing could be possible by 2020-2025.

In conclusion, so far the human brain is far more advanced and efficient, and possesses more raw computational power than the most impressive supercomputers that have ever been built.
