Computer has been an important gadget in many peoples life. Computers come in various design, size and types. For example, there are computers that needs to be placed on the desk or on a flat surface like the desktop computer and the laptops. Where else we have the computers that can be carried along with us like the mobile phones and tablets. Computers are so important that it is used to communicate by billions of people. For example people use computer for far distance communication like sending emails to friend and workmates or talking to family members at any time without restriction and this is really convenient. Computers are also used for working purpose like the consumer using it for business, employees to employers as well as customers. (Gary B.Shelly 2011). Computers are also used for education in schools, library, and at homes as well by students, adults and kids. Computer is a very helpful medium to learn knowledge and information. In this 21st century, nothing works without the basic knowledge in computer for example a small shop uses computer to keep the records of thing that they have sold and even a road site food stall uses the calculator which is also a computer to count the price. Compare to the past era children used to play out door games but in recent era children prefer to play indoor with their computers. Today I will be writing about the modern history of computing since it is really important to know the history of computer.
HISTORY OF COMPUTING
According to history, human clerks where well known as computers which helped in calculating effectively. The calculation done by the human computers which nowadays are carried by the electronic computers, human clerks worked in commerce department, research faculties and the government as well. The name computing machine, were used progressively starting from 1920s, it was referred to any machine that did the job of human computers for example any machine that does the job of human computers in effective method. In the late 1940s and early 1950s, the articulate ‘computing machine’ were changed to simpler word ‘computer’. (N.Zalta 2006).
In year 1828 to 1839, Charles Babbage was a Professor of Mathematics at Cambridge University. (N.Zalta 2006). The Difference Engine which was suggested by Babbage was a special intend digital computing machine for the use of mathematic tables which can produce automatically. The Difference Engine was mostly occupied with mechanical components. For example with metals, rods and brass gear wheels. To make a more general purpose mechanical digital computer, Babbage proposed the Analytical Engine. In the Analytic Engine, it was proposed to have the central processing unit and a memory store. The characteristic of the Analytic Engine can be dominated by the program that has been instructed in the punched cards which is put together with ribbons. Babbage stressed the simplification of the Analytical Engine, by saying “the...
