Human Brain vs Computer

 

Key Differences Between Brain and Computer

1. The brain can have 100 teraflops of memory with a density of 107 circuits per cm3 while computer memory has the 100 million megabytes with a density of 1014 bits per cm3. Memory in brain grows instantly just by connecting synaptic link whereas in a computer to scale the memory the chips need to be added.
2. Brain has the inbuilt backup system where the functioning pathways replace the damaged pathways. As against, backup systems are constructed manually in a computer.
3. The energy consumption in the brain is less than the computer.
4. To store information the brain uses electrochemical and electromagnetic form. Conversely, in a computer, the information is stored in the symbolic and numeric form.
5. In the brain, the information is transmitted with the help of chemicals to fire action potential in the neurons. On the contrary, the computer uses electrically coded signals to transmit the data.
6. The processing power of the brain is unlimited and provides online processing, but the brain processes information at slow speed because neurons are slow in action. In contrast, the processing power of computers is significant because of fast transistors.
7. The brain is self-organised while the computer is preprogrammed structure.
