Computers know nothing about language. Actually, when you get right down to it, they know nothing of numbers either. All that computers know is on and off. They can change the ons and offs based on other ons and offs. If certain ons are on, the processor will do one thing; if they are off, it will do another. A computer is perfectly happy with this arrangement.
However, the purpose of a computer is to do work for a human.
IBM inventors received a record 5,896 U.S. patents in 2010, marking the 18th consecutive year IBM has topped the list of the world’s most inventive companies. IBM became the first company to be granted as many as 5,000 U.S. patents in a single year. It took IBM's inventors more than 50 years to receive their first 5,000 patents after the company was established in 1911.
