Without dragging on a long history and kill the excitements, I would just get started here, Charles Babbage created the first computing machine in 1822. He wasn’t planning to actually built a real computers that had millions of software’s in it but indeed a computer that actually solved math problem. He was sick of correcting math problems that all human brains couldn’t solve, therefore he thought of inventing something that would help him solve the headache, but then what he finally was a computer. Computer! What is an computer. As we all know computer is device storing and processing data, typically that binate, according to instructions given to it in a variable program. Computers are also known as PC, laptop, netbook, ultraportable, desktop or even terminal. A brief history on how was a computer was invented, computer was originally found being used in 1613 that meant “ humans who perform calculation and computations. The definition of a computer never changed until 19th century when humans began to realize machines never get tired and can perform calculations much accurately and effectively than any human beings that could ever do. More on, in World War II, mechanical analog computers were used for specialized military applications. During this time the first electronic digital computers were developed.the digital computers were a size of a large room,and it consumed power as 50 over personal computers. The machine contained fifty-foot long camshaft that carried the machine’s thousands of component parts. To prodeuced mathematical tables the MARK -1 was used but than soon it was superseded by stored program computers.

Knowing its functions can help you decide if the iPad is right for your business needs. This contains, media center, web browser, message hub, organizer and planner, and social media manager, such a handy devices that has all in it. To a 2years old infant up to old folk everyone prefers this smart devices as they don’t consume a room space, much power or nor its not heavy. As I believe this world of invention would not sleep until our genius brother inventors turns this earth to a space that will be then called ‘THE WONDERS’ . I believe that there will be more changes persuading in the years to come as we have already travelled so far.
Technology is evolving and growing as fast as Moore’s Law has predicted. Every year a new device or process is introduced and legacy devices becomes obsolete. Twenty years ago, no one ever thought that foldable and paper screens would be even feasible. Today, although it isn’t a consumer product yet, foldable and paper screens are a reality. Home automation, a more prominent example of new technologies that were science fiction years ago are now becoming an integral part of life. As technology and its foothold in today’s world grows, its effects on humanity begin to show and much more prominently than ever. In his essay, O.k. Glass, Gary Shteyngart shows the effects of technology in general and on a personal note. Through the use of literary
In previous years, the first computers were mechanical, not electronic. One of the first computers ever made was the Difference Engine, designed by Charles Babbage. (Babbage, C, n.d.). The Difference Engine was able to calculate polynomials using the differences method. After the Difference Engine, Babbage began his work on an improved calculating engine, the Analytical Engine. The Analytical Engine used punch cards to operate, just like the Jacquard Loom. The Jacquard Loom used punch cards to control weaving that created interesting patterns in textiles. The punch cards were used in the Analytical Engine to define the input and the calculations to carry-out. The Analytical Engine had two major parts. The first part was the mill, which is similar to a modern day computer processing unit, or a CPU. The CPU is the brain of a modern day computer; it is what carries out modern day instructions inside a computer. The mill would execute what it received from the store. The second part was the store, which was the memory of the computer. “It was the world’s first general-purpose computer.” (Babbage, C, n.d.)....
In 500 B.C. the abacus was first used by the Babylonians as an aid to simple arithmetic. In 1623 Wihelm Schickard (1592 - 1635) invented a "Calculating Clock". This mechanical machine could add and subtract up to 6 digit numbers, and warned of an overflow by ringing a bell. J. H. Mueller comes up with the idea of the "difference engine", in 1786. This calculator could tabulate values of a polynomial. Muellers attempt to raise funds fails and the project was forgotten. Scheutz and his son Edward produced a 3rd order difference engine with a printer in 1843 and their government agreed to fund their next project.
Mark I. It was actually a electromechanical calculation. It is said that this was the first potentially computers. In 1951 Remington Rand’s came out with the UNIVAC it began
Even as I sit here typing this paper, my own shiny, rectangular piece of molded plastic and metal lies inches away from my fingertips, beckoning me to use it. Looking out the window, one of the first sights I see are people walking with one hand up to their ear, evidence this technology is in use. I can count on one hand the number of adults I know who do not own one these mobile devices. People are now able to be virtually accessible almost anywhere at any time.
Born December 26, 1791 in Teignmouth, Devonshire UK, Charles Babbage was known as the “Father of Computing” for his contributions to the basic design of the computer through his Analytical Engine. The Analytical Engine was the earliest expression of an all-purpose, programmable computer. His previous Difference Engine was a special purpose device intended for the production of tables. Both the Difference and Analytical Engines were the earliest direct progenitors of modern computers.
In 1964 what started out as machines used for calculating complex problems turned into technology that can be more accessible to the public when Douglas Engelbart shows a prototype of the modern computer, with a mouse and a graphical user interface (GUI). The computer was created to solve a serious number-crunching crisis. By 1880 the U.S. population had grown so large that it took more than seven years to calculate the U.S. Census. The government required a faster way to get the job done, which led to the creation of punch card computers which were as large as an entire room. (livescience) The computer has come a long way in the past 40 years. In 1976 Steve Jobs and Steve Wozniak start Apple Computers, but it wouldn't be until 1983 that Apple would release a computer with a GUI(graphical user interface). A GUI uses windows, icons, and text that can be manipulated by a person to communicate to the computer. Two years later Microsoft launched Windows, which is their response to Apple.
Charles Babbage is the father of computing after his invention and concept of the Analytical Engine in 1837. With a basic flow control, and integrated memory, the first general purpose computer concept was born. It was later that, Charles’ son Henry Babbage completed a portion of this machine and the computer was able to perform basic calculations. Having no invention of a computer, the Babbage are known as the father of computing is due to the ideas and concept he visualised at that point of time.
Charles Babbage is an English mathematician, mechanical engineer, inventor, writer, and philosopher. He was considered as the Father of the Computer because of his invention and concept of the first mechanical computer, the Difference Engine and the first general-purpose programmable computing machine the Analytical Engine. The Analytical Engine’s features resemble the principles found in the modern digital computer we are using today.
The fist computer, known as the abacus, was made of wood and parallel wires on which beads were strung. Arithmetic operations were performed when the beads were moved along the wire according to “programming” rules that had to be memorized by the user (Soma, 14). The second earliest computer, invented by Blaise Pascal in 1694, was a “digital calculating machine.” Pascal designed this first known digital computer to help his father, who was a tax collector. Pascal’s computer could only add numbers, and they had to be entered by turning dials (Soma, 32). It required a manual process like its ancestor, the abacus. Automation was introduced in the early 1800’s by a mathematics professor named Charles Babbage. He created an automatic calculation machine that was steam powered and stored up to 1000 50-digit numbers. Unlike its two earliest ancestors, Babbage’s invention was able to perform various operations. It relied on cards with holes punched in them, which are called “punch cards.” These cards carried out the programming and storing operations for the machine. Unluckily, Babbage’s creation flopped due to the lack of mechanical precision and the lack of demand for the product (Soma, 46). The machine could not operate efficiently because technology was t adequate to make the machine operate efficiently Computer interest dwindled for many years, and it wasn’t until the mid-1800’s that people became interested in them once again.
In the early 1800’s, Charles Babbage began a life long quest for a programmable machine. (A brief 2004). He invented machines that are called as calculating engines. Engine number one was the first successful automatic calculator that was able to work on its own. This calculator consisted of over 2000 parts (The early 1996). A large problem that Babbage had would be many engineering problems which would not allow his engines to work correctly. He is remembered and is important to computer history because of his idea for the machines. His basic ideas of how the machine would process information is still used to this day (In the beginning 2004).
Computer engineering started about 5,000 years ago in China when they invented the abacus. The abacus is a manual calculator in which you move beads back and forth on rods to add or subtract. Other inventors of simple computers include Blaise Pascal who came up with the arithmetic machine for his father’s work. Also Charles Babbage produced the Analytical Engine, which combined math calculations from one problem and applied it to solve other complex problems. The Analytical Engine is similar to today’s computers.
One of the main contributors to the foundation of modern computer science is Charles Babbage. Born into a wealthy family, Charles was unhindered by financial burden for the majority of his life and was therefore able to pursue his personal interests freely. Eventually he attended Cambridge University in order to study Mathematics. Quickly realizing he was mentally years ahead of his teachers, he gradually moved away from classrooms and began to seek likeminded individuals. Charles eventually met John Herschel and George Peacock and formed the Analytical Society in which he drastically helped in weakening the grasp of Isaac Newton’s theories that were deeply engraved at the university. After years of research, he eventually began designing a machine called the Difference Engine; an invention that would become the basis for the first computer. It was capable of calculating a sequence of numbers to the 7th polynomial and would be able to print hard copies of the results for recordkeeping. Unfortunately due to financial disputes he was never able...

Computer history goes back to the 1800s when Charles Babbage created the first computer, named the Babbage model. It was an analytical model that was composed of gears and levers and was about the size of a desk calculator ("Computers" Ferguson's Career Guidance Center). Computers that used vacuum tubes to store space concepts were considered first generation computers. Overtime, computers became smaller, faster, more reliable, and much easier to use than the previous models. In 1971, the first microprocessor was invented, which led to the fourth generation computers, which are used to this day. By the 1980s, competition among companies, such as IBM, Apple, and Packard Bell, resulted in lower prices for computers ("Computers"). Now, computers are affordable for businesses, schools, and homes.
