Human adept and Computer - Essay ExamplePossibly, it dismiss be said that the nous is better at doing close to specific jobs and the computing machine is good at doing other jobs. This paper is intended to analyze the benefits and limitations of the metaphor the sense is often comp ard to a computer which is commonly utilise by many.Before getting into the details it is outstanding to understand why such a comparison was made. Theoretically the brain is a machine only if as the heart and kidney. It can be said that the brain is a computer (processor) with neural connections, programmed responses, and a data bank. It has sensors in the body that input information into the computer. It has an output to devices that perform actions, and the brain communicates with these devices through galvanizing and chemical channels.The comparison of the brain and the computer is a metaphor. In general metaphors are just use to help us better understand things. Or in other words metaphors a re used to convey the idea that one thing is similar to another thing. They are useful for helping us understand things, such as mind/body interaction. Metaphors do not mean that both the things compared are one and the same neither is one thing is a substitute for the other.Since some(prenominal) processes in the brain are similar to the computer, it is commonly compared with each other. For instance, both brain and computers use electrical signals to transmit information. two have a holding which tends to grow over time. With proper instructions given, both brain and computers can learn. Both work based on the energy present. Brain and computers are able to think logically and do math. There are also differences between brain and the computers. For instance, brain uses chemicals such as atomic number 20 and sodium to transmit information where as the computer uses electricity. Electrical signals generated in the brain travels much unhurried when compared to computers. A compu ter uses switches that are either on or off and works on the binary star system, where as the brains do not have such a system. Memory of the brain generally grows by stronger synaptic connections but in a computer it is only possible by adding additional memory chips. The brain needs essential nutrients such as oxygen and sugar for working where as the computer only require electricity or a battery to keep working (faculty.washington.edu, N.D.). Though cashbox date the technology had not grown to replace the brain with a computer, there have been several advantages with the development of this technology. For instance, today it is possible to use computer inputs as substitutes for other sensory inputs, and for outputs to limbs or devices to realize movement of neurologically damaged limbs, control the environment by sensing the brains electrical impulses, and even create contain forms of sight. Besides, great steps are being made in bionics, including artificial hearts that wor k for interminable periods. In recent years study is under progress for replacements for muscle made from specialized ceramic or polymer materials that contract like muscles, which can be triggered by a computer. With this trend of advancement in technology, perhaps one day we could also replace computers with brain (Cole, 2003). A person can do many things which a computer cannot even attempt to do it. A brain beyond disbelieve has one thing that a computer doesnt and this is a major difference. A brain communicates with itself and the body
