Robert Birge (Syracuse University) who studies the storage of data in proteins, estimated in 1996 that the memory capacity of the brain was between one and ten terabytes, with a most likely value of 3 terabytes. Such estimates are generally based on counting neurons and assuming each neuron holds 1 bit. Bear in mind that the brain has better algorithms for compressing certain types of information than computers do.

The current P55 chipset supports 6 sata ports so you can add 6 2TB hard drives to a normal home PC for a 12 TB capacity.

What is the importance of computer as a tool for data processing?
increase accuracy Efficient storage facilities Handles repetitive task
Man vs computer?
1)Computer can do only mathamatical work but human can do both phycial,Logical.. 2)Human can think in different angle but computer does not 3)Memory capacity is high for computer but normal for human being 4)Human can use computer but cannot use man 5)Computer is Stupid machine for every work we have give commands ,but man to his own knowledge 6.) Computer cannot think of its own, but man does. 7.) Both are affected by viruses. 8.) Computer can calculate at higher speeds than man. 9.) Memory is limited for computer, but for man it is unlimited (but recollecting is difficult!) 10.) Computer can do monotonous work without getting tired, but man seldom loves to do that.
Is human interface device and human computer interface is similar?
a human interface device is the device the human uses to communicate with a computer, like a mouse or keyboard. Human computer interface refers to all of those working together to let the human control the computer.
What is the limitations of computer?
The fundamental problem with computers is that it doesn't have a human mind i.e. I cannot think like human. It's "thinking process" will involve a set of confined rules and it's thinking will never get out of the boundaries of that rules and regulations. =========== LIMITATION OF COMPUTER Computer has done this and that. Actually this is not the computer which has done this but the user. Despite its various features, a computer does have the following limitations: a. No Self Intelligence Today, a computer is able to do a work which is impossible for man. Computers are used to do risky and dangerous work and where sharp actually is needed. But it does not have any intelligence of its own. It works according to the instruction only. b. No Decision-Making power Computer cannot take any decision of its own. It does only those tasks which are already instructed to it. c. No learning power Computer has no learning power. Once you give instructions to a computer how to perform a task, the very task is cannot perform if you do not give it any instructions for the next time. For example, when you are taught how to solve a problem and it same type of problem is given to you to solve, then you can do it because you have learned how to solve the problem. The computer can outperform human beings in speed, memory and accuracy but still the computer has limitations. There are following limitations of a computer. =========== Programmed by human: Though computer is programmed to work efficiently, fast and accurately but it is programmed by human beings to do so. Without a program, computer is nothing. A program is a set of instructions. Computer only follows these instructions. If the instructions are not accurate the working of computer will not accurate. Thinking: The computer can not think itself. The concept of artificial intelligence shows that the computer can think. But still this concept is dependent on set of instructions provided by the human beings. Self Care: A Computer can not care itself like a human. A computer is dependent still to human beings for this purpose. Retrieval of memory: A computer can retrieve data very fast but this technique is linear. A human being's mind does not follow this rule. A human mind can think randomly which a computer machine can not. Feelings: One of the main limits in the computer is of feeling. A computer can not feel about some like a human. A computer can not meet human in respect of relations. Human can feel, think and caring but a computer machine itself can not. A computer can not take place of human because computer is always dependent of human.
Why is a computer more efficient than a human being?
Who said that a computer is more efficient than a human being ? Can a computer reason, think, consider. These are some of the human qualities that a computer will never be able to achieve regardless of future technologies. This is in my humble opinion of course. I am feeling tired now and cannot type anymore and will have to recharge my human batteries
Why are the limitations of computer?
Cannot think like a human. In fact, computer do have limit storage while human has infinite storage of information.
When the computer is better than human?
The computer is better than human beings in data processing because computers are faster, more accurate and have way higher storage capacity than the human brain. Also, computers don't grow tired or bored even if made to perform repetitive tasks.
What is the importance of computer as a tool for data processing?

How did computer come to the world?
Computer is a system for input data, storage devices, analysis and processing information, human
What parts of a human function as a computer's input storage memory processing and output?
the brain
Which is greater human brain or computer?
The brain controls more but the computer has more knowledge.
What is difference between elelectronic storage and hard copy storage?
Electronic Storage is usually referring to data stored on some type of computer related storage medium, such as hard drives, CDROM, memory cards, etc. In other words, its data in computer form, 1's and 0's, stored in a format that a computer understands. Hard Copy storage would be on paper or the equivalent, stored in human form and readable by us.
Give the characteristic of computer?
1.It very fast as compare too human, as it takes very few time to process the instruction given by user 2.Its storage capacity is very vast as compare to human , trillions and trillions of datas can be stored in computer 3.It is very accurate , means it does not make any errors until and unless given instructions has got errors Given by Azmat
What are the psitive effects of computer in environment?
the positive effect of computer in environment: 1. computer can help our work to make convenience. 2. its capability are greater than human.
Explain about the storage capacity of computer?
Currently, inside a regular desktop PC the largest unit of size would be 1 TB (1000 GB), and with this unit it becomes very difficult to completely fill the storage device. However, potentially, the largest is the yobibyte, which is a whopping 10,000,000,000,000,000,000 bits of data. Basically, if scaled down into human language it would be the information capacity of the observational universe, meaning every bit of known knowledge ever recorded, translated into every language and coppied 10,000,000 times over.
Why was the first computer invented when it was?
need for greater computation speed & reliability than human computers were capable of.
What is human intellectual capacity?
Absolutely limitless it would seem. We may just have an 'external storage' device separate to our minds that allow us to be so great!
