What are the similarities and difference between the human brain and the fifth generation computers?

Answer 1

With some reasons, the computer is compared with the human brain. Like the brain that devised it, a computer can take data and process it. It can store the data either in raw form or in the form of processing results, and can deliver the raw or processed data to the outside world on demand.

Answer 2

1. Computers rely on electricity, whereas humans rely on food.

2. Computers have the potential to increase the speed of their impulse transmission exponentially as opposed to humans.

3. Computers have a better ability for multitasking.

4.Computers are good at computations and logic, while humans are exemplary in reasoning and imagination.

Answer 3

The human brain - We can only estimate the processing power of the average human brain as there is no way to measure it quantitatively as of yet. If the theory of taking nerve volume to be proportional to processing power is true we then, may have a correct estimate of the human brain's processing power.

It is fortunate that we understand the neural assemblies is the retina of the vertebrate eye quite well (structurally and functionally) because it helps to give us a idea of the human brain's capability.

The retina is a nerve tissue in the back of the eyeball which detects lights and sends images to the brain. A human retina has a size of about a centimeter square is half a millimeter thick and is made up of 100 million neurons. Scientists say that the retina sends to the brain, particular patches of images indicating light intensity differences which are transported via the optic nerve, a million-fiber cable which reaches deep into the brain.

Overall, the retina seems to process about ten one-million-point images per second.

The computer - Computers have more than one form of memory. We can generally classify them into primary and secondary memory. Primary memory is used as a form of temporary memory for calculation processes and storage of temporary values that need rapid access or updating, the contents of the primary memory disappear when the power is turned off. Primary memory is important when executing programs, bigger programs require more primary memory. ( RAM(random access memory), Caches & buffers are just a few examples of primary memory)

Secondary memory often comes in the form of hard disks, removable disk drives and tape drives. Secondary memory is used for the storage of most of a system's data, programs and all other permanent data that should stay there even when the power is turned off. As a computer is fed with bigger, smarter programs and more data, it would naturally need more secondary memory to hold them.

The latest, greatest super computers (as of 1998) have a million megabytes of memory. Today's latest model of hard disk drives on the personal computer market (in early 2000) can hold about 40,000 megabytes

(40 gigabytes) of memory.

Answer 4

If you accept that a computer has a brain (which they do not as yet) then it is not 'better', it is different.

Computers have some abilities which make them preferable to human (brains) for carrying out some activities.

... They can respond faster to certain situations and do complex analysis to decide what to do.

... They can be used in places where it would be too dangerous for a human.

... They can carry on monitoring something for days and days without getting bored and falling asleep.

... They can remember more and store it for faster searching than one human can

... They don't have to spend 8 hours a day sleeping and several hours feeding

... They don't expect to be given four weeks paid holiday every year.

On the other hand

... they can only ever do what they have been programmed for - humans (well most) can solve new problems which they have no previous experience or training for

... they stop if the power goes off - most humans will find a way to carry on if it is important to them

... if the program is wrong the results are wrong - humans can spot their own mistakes (sometimes)

... they have no moral sense, they don't know right from wrong - so will run a virus just as happily as a spreadsheet.

Answer 5

Computer works as per the input given by the human and human works as per the knowledge he gained from various sources and experiences.

Answer 6

The computer is digital whereas the brain is analog.

Answer 7

computers are smarter and humans can think (are self aware/Living).

Answer 8

fast ? 10 petaflops

Answer 9

yes
