The Computer In my prospective Work
The 10 different computer functions for my future work.
First i need to prepare my site's program
I get gonna domain and host
I'll need the computer in order to create the design of site.
I must do much more work after the site growing. It's necessary so workers. I can use computer to calculate their salaries and then to print it.
I can advertising by sharing and introducing.
I shall need to prepare different rulers about site
I can do publicity in diffenent cities and countries
Me and my workers will comnucate over the internet with customers
I'll prepare utilities for the site
To play game in time of rest.
Fist programmer
Ada Lovelace is popularly credited as history's first programmer. She was the first to express an algorithm intended for implementation on a computer, Charles Babbage's analytical engine, in October 1842. Her work never ran, though that of Konrad Zuse did in 1941. The ENIAC programming team, consisting of Kay McNulty, Betty Jennings, Betty Snyder, Marlyn Wescoff, Fran Bilas and Ruth Lichterman were the first working programmers.
The First Mechanical Calculator
Blaise Paskal, noted mathematician, thinker, and scientist, built the first mechanical adding machine in 1642 based on a design described by Hero of Alexandria (2AD) to add up the distance a carriage travelled. The basic principle of his calculator is still used today in water meters and modern-day odometers. Instead of having a carriage wheel turn the gear, he made each ten-teeth wheel accessible to be turned directly by a person's hand (later inventors added keys and a crank), with the result that when the wheels were turned in the proper sequences, a series of numbers was entered and a cumulative sum was obtained. The gear train supplied a mechanical answer equal to the answer that is obtained by using arithmetic.
This first mechanical calculator, called the Pascaline, had several disadvantages. Although it did offer a substantial improvement over manual calculations, only Pascal himself could repair the device and it cost more than the people it replaced! In addition, the first signs of technophobia emerged with mathematicians fearing the loss of their jobs due to progress.
