Comparison and Contrast

Comparison and Contrast between Human Brain and Computer

About 1.5kg
From a few grams to tones
Energy source
Blood glucose
Temperature needed
Fairly steady
Not very sensitive to changes
Number of parts
Approximately 10^11
Approximately 10^11
Inside skull
Could even be in different countries
Probably unlimited capacity
Capacity limited by technology
Speed of calculation
Quiet slow
Extremely fast

              The first computer to be developed was all large Mainframes computer and this type of computer is still very much today used. A modern mainframe is can carry many different jobs at same time and can be used with many users. Each user access the mainframe through a terminal who acts as input device and output device.
               Many computers are cheapest, smallest, and slowest than mainframes. They rarely occupy more than one room, and often used for a particular time of work such as data analysis in a research laboratory and soon. These kinds of computers are commonly known as PC’s. Since these computers are cheap for some individuals today to buy. This computer is also an example of lifetime to prove the power of human and their advancement in science.
            When we compare a human being with computer it is not possible to prove that the computer can perform well than its master. Because the human brain performs various activities and which weight’s about 1.5kg where as the computer which differs from very few grams to tones. For human brain blood glucose which supplies the energy source on the other hand electricity can be the only energy for a computer. When temperature needed for a human brain it accepts fairly steady temperature but in the case of computer it differs from country to country and even it is not very sensitive to the temperature changes.
            Human brain which is located inside the skull but for computer it could even be in different from country to country. Human brain as well as computer has the same number of parts however the function differs in both. When the memory capacity is compared with computer; it is limited by technology where as human brain has unlimited capacity to spread its ages. The speed of calculation in computer is extremely fast than the human brain.
             However computer is a manmade device even it can perform well than human being but the computer cannot be equal or can compete with wonderful human brain.
