HISTORY OF COMPUTERS The abacus was an early aid for mathematical computations. Its only value is that it aids the memory of the human performing the calculation. A skilled abacus operator can work on addition and subtraction problems at the speed of a person equipped with a hand calculator. The abacus is often wrongly attributed to China. In fact‚ the oldest surviving abacus was used in 300 B.C. by the Babylonians. The abacus is still in use today‚ principally in the far east. A modern abacus

So to turn on coil C only‚ a binary number 1011 (in hexadecimal “b”) is needed and the code for it is shown as follows: cbDout(BOARD_NUM_0‚FIRSTPORTA‚0xfb) Similarly to turn on coil C and D‚ a binary number 0011(in hexadecimal “3”) is

numbers. Assembly language‚ unlike machine language‚ is a symbolic representation of operation codes‚ symbolic memory addresses and pseudo codes‚ which makes the virtual environment user friendly. Machine language‚ on the other hand‚ is represented as binary bits consisting of a string of 0s and 1s‚ which makes the virtual world challenging since the lingo is only comprehended primarily by computers. Therefore‚ assembly language is considered more user friendly than machine language. Assembly language
