UNDERSTANDING COMPUTERS

Humans communicate with each other in many languages. The most commonly used languages are English, French, German, Spanish, Chinese and so many other languages. However computers understand only one language which is the binary language of ones and zeroes. Though we give instruction to the computer in normal human understandable English it does not understand it as it is. It interprets the high level human code to low level machine language so that it can perform the particular work. All this inter conversion is not visible to the normal human eye but happens internally. This internal conversion is difficult to understand as these are machine generated codes. All data given is converted to a combination of  ones and zeroes. Boolean algebra was developed to deal with binary numbers. Under the binary system all ordinary arithmetical operations are reduced to their simplest form. The binary system of numeration was used early in the seventeenth century by Thomas Harriot.
