HISTORY OF COMPUTERS Ancient era Suanpan (the number represented on this abacus is 6‚302‚715‚408) Devices have been used to aid computation for thousands of years‚ mostly using one-to-one correspondence with fingers. The earliest counting device was probably a form of tally stick. Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres‚ cones‚ etc.) which represented counts of items‚ probably livestock or grains‚ sealed in hollow unbaked clay containers.[1][2]

selected a certain sample. Our sample was a specified one. Generally people who are familiar with using internet were the sample people. There are still a lot number of people who are not familiar with the use of internet or even with the use of computer‚ so people who are well acquainted with the use of internet were our sample. They were made to fill the questionnaire and a simple informal interview was taken during the time the questionnaire got filled. Then the results were analyzed and then

to perform operations on data.[1] Quantum computers are different from digital computers based on transistors. Whereas digital computers require data to be encoded into binary digits (bits)‚ each of which is always in one of two definite states (0 or 1)‚ quantum computation uses qubits (quantum bits)‚ which can be in superpositionsof states. A theoretical model is the quantum Turing machine‚ also known as the universal quantum computer. Quantum computers share theoretical similarities with non-deterministic

Periventricular Leukomalacia (PVL) is a diagnosis that is not very familiar to many people. This is a brain injury that occurs in infancy. This injury is most common in preterm babies but can still happen in full term babies as well. 75% of preterm babies with Periventricular Leukomalacia will have some kind of disability. Many people do not know what causes this‚ how this is diagnosed‚ what the treatment is and the outcome of the infants affected by this. This paper will give insight to what causes

example of computers of the future. To control computer‚ to give him a mission‚ to tell what it should do – all that we will be able to do with the help of our brain. All computer needs are neurons and impulse accessed from the surface of the human body‚ or muscle impulses picked up by electrodes on the arm‚ hand‚ face or forehead generated by physical movement. So when our brain will be active‚ our neurons start to work harder‚ we can replace a folder on the desktop for example‚ computer will understand

The Simple Computer POST Power on self-test (POST) is a test which the computer completes on start-up which will verify whether the hardware is all working correctly. If the hardware is working correctly the computer will continue to boot if not a beep code is generated. A BIOS may have a different beep code depending on what type of BIOS it is.
