how is the human mind and body compared to a computer?

The Cerebellum is the "CPU". It processes all the information. It is also the "USB port" because it is linked to the spine, or "USB cord". The lobes are the "Hard drives, CMOS" The sides are the keyoard and mouse, because they are the input devices.

Past - Really Big Calculators. Originally considered no more than a number cruncher, 'programs' were primarily business oriented. Accounting, Scientific, etc. At the time, only a handful of people on the planet ever considered they would be more than the 'science fiction' movies of the time portrayed them.\nPresent - Computer jargon is very much a part of our ordinary lives. Nearly every appliance in a modern house contains more computing power than that which ran the moonshot missions. A significant percentage of the world's populace could not conceive of a world without computers. More than business, computers are our entertainment, our transportation, communication, our virtual life.\nFuture - Further human integration. Smart Computers will run our everyday lives: feeding us, tools for work & play, our sole means of communication with those around us. Further progress for implants into humans will allow 'hands free' operation. No money, cards, phones, etc. will be required past the optics to access personal links to the worldwide net.\n\nIf we happen to survive that long.

Actually, the brain uses electrical AND chemical messages.  I believe this is one of the reasons the brain is able to acheive such complexity of operation.  Computers are not currently capable of that same complexity, and my theory is that the computers are limited by the fact they use ONLY electrical data.  By combining electical and chemical messages, the computing capabilities are expanded exponentially.  No source for this.  It's just my personal hypothesis.

It really depends on how you gauge intelligence. Now, if everyone thought that people were smarter, then there would be no worry of machines ever taking over the world. \n\nThe fact is, a computer can process information a lot quicker than a human can. Ultimately, we create machines that can outperform us in velocity and force, which is also true of a computer. That is the point of making them. A computer can be as smart as one programs them. We possess so many other possibilities within our brains and through our senses.  \n\nWe really only define our thought through the senses we perceive and draw unique conclusions, even expanding the bounds of reason. It is this expansion that gives way to new discoveries and understanding, hence, people on the whole are smarter. \n\nUnless we can create a computer to attain consciousness, but even then, we will have to be cognitive masters before we can do that. People are smarter than computers, because although a computer may process information faster and recall memory quicker, we are the ones that have the ability to expand the parameters of reason and logic. Machines are faster and stronger than we, but not smarter. We utilize speed and function in a machine to accomplish tasks, and a computer may only appear smarter due it's processing speed.

you could draw comparisons, but each bit in computer works by either sending a voltage down a conductor or not. It is either on or off. Each bit sends its pulses to a register where the queue up for the processor. A 64 bit processor can process 64 bit every two or 4 clock cycles (depending on how the register works). So a 1 GHz computer can process 64 bits half a million times a second.\n\nEach neuron in the brain has many conductors coming out of it. So it can send pulses down one, two, three or many conductors to other neurons, which in turn do the same. Pretend one neuron has 8 pathways coming out, that gives 8x7x6x5x4x3x2x1 switching combinations for one cell, Thats about 40 000 combinations from one cell. Some neurons have more than this some have less. Either way it is a big difference to on or off. Factor all this by the number of nuerons in a brain and you have one complex system. Eg 2 cells gives 40000 x 40000 combinations. 3 cells give 40000x40000x40000 combinations 40 000 to the power of a few million give a massive number of switching combinations.\n\nThe other difference is that the neurons wire themselves up based on your experiences. \n\nOne similiarity is levels of memory. Fine motor control is kept in permanent up front memory. people names are kept somewhere to be triggered by facial recognition and take a while to drag out of memory.\n\nA computer keeps the commonly used stuff in L1 and L2 cache, then main memory, then hard drive.

It depends on what you are trying to do.\n\nIf you are trying to find intersellar radio signals in the nighttime sky (SETI@Home), computers are much more efficient. If you are trying to navigate a vehicle across rocky terrain (DARPA Grand Challenge) apparently humans still beat computers at that pretty handily.\n\nThat doesn't mean that computers won't one day be better at off-road navigation than people, but such is not the case at today's state of the art.

They are the same, lol.\n\nThe differences lie in Tablet PCs (which have a graphics-tablet note-taking touch screen), and normal laptops.\n\nHP do some good cheap laptops. If you wanna look the biz, get an Alienware Sentia.

according to http://sigchi.org/cdg/cdg2.html\n\n"Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them."\n\nTo me this means...\n\nHow humans and computer (and equipment) interact. This could be with blind people, deaf, handicapped, paralyzed, etc, etc, or even just a person working a grapics program. The other side of this is how the computer (and equipment) interact with the human.

Nope, The computer is a substitute.  We do this because we are missing something elsewhere.  If we find peace and satisfaction, we won't be on this gig any more.  What are you missing?

its a very broad question.  \n\nthe human mind is incredible for retrieving information with details, associating picture memory, with smell and words. how things feel taste..  It also is wonderful for imagining things concepts and creativity.  the human brain has the ability to adapt to things and reason, it can think concepts and fiction.\n\nComputers work differently, they are good at remembering things that have no pattern simply electrical charges in a set order.  A machine designed to keep refreshing that information.  sensors can input information, but the more complex the info the more computing power needed to make sense of it.  \n\ncompare a computer driven car compared to a fighter pilot.  the incoming information in shear data what your brain receives from the senses and throws away useless info before you even realize you saw it.   \n\nYour eyes take in everything.  you brain ignores anything it doesnt feel important.  computers didnt get there yet.

life for sure will be different...\nit would really seem like the world is a really big place...\nwhich is contradicting of having computer...\nwherein we can now tell...\nit's a small world afterall...\n\n=)

Indeed it is fascinating!  \n\nAnother thing I always thought was neat was the way some connective tissues of our bodies work.  Bone, cartilage, elastic tissue, and many types of extracellular matrix that provides support for our organs work in the same way that cement does; a matrix of proteins filled with a sort of goop of compounds that holds it all together, just like a wire mesh filled with cement.\n\nPerhaps even more interesting is the way our brains work like computers (or rather, the way computers work like our brains!).  There are really only two positions a neuron can take: 'on' and 'off'.  This is not unlike the binary code that processors use.  Of course, brains are a lot more complex, and use a variety of messengers beyond just electrons.

How can one define anything, not to mention, what makes us more of an intelligence and not a computer? The real question is, how would you define an intelligent computer (if there is even a difference)?
