Computer Programming is a big industry. Without it, computers, video games, the internet, and even cell phones would not exist. Jobs are not scarce for computer programming today. Almost everything we use has to do with technology, and computer programmers are needed in order to make the projects happen. Computer programming is one of the more challenging jobs out in the world. Someone who quits easily when things get hard, or when something is not working the way that they want it to, will not succeed in computer programming. It takes a lot of time and dedication in order to complete a task for an employer. When it comes to computer programming there is a lot of history. (Ferguson) It all started with the invention of the difference engine. (Ferguson) It was made by Charles Babbage in 1822. (Ferguson) Computers require a means of instructing in order to complete a task. (Ferguson) “Computer languages were first composed of a series of steps to wire a particular program; these morphed into the computer and then executed; later these languages acquired advanced features such as logical branching and object orientation” (Ferguson) Byte was the first computer language. (Ferguson) Byte is comprised of 0’s and 1’s. (Ferguson) The programmer had to translate the code of the program by hand in order for the computer to read it. (Ferguson) It was the first major step towards the advanced computer languages of today. (Ferguson) Grace Hopper wrote the first compiler “A-0” in 1951. (Ferguson) The compiler translated the programmer’s code into 0’s and 1’s automatically, thus allowing programs to be completed faster, as the programmer no longer had to translate the code by hand. (Ferguson) The first major languages first appeared in the for... ... middle of paper ... ...closes, can take up to 50 lines of code, or even more! So an advanced program, such as Adobe Photoshop, can not be programmed in just one day. Even if you were sitting there, copying down the code, it would take more than 24 hours, because of how much programming it took. Works Cited Bonnice, Sherry. Computer Programmer.

In the beginning of this week, I tried to continue and complete the reading of the previous unit as I'm not just interested in having good grades in my assignments without reading all the materials, but really insist on learning in order to have a solid base in computer science that can boost my carrier. So I started to read the "Problem Solving and Programming Design" and the "Problem Solving Basics" documents and I really enjoyed them as I learned how to decompose a problem in order to design an algorithm and to provide a good and consistent program.
“The BINAC (or Binary Automatic Computer) was the first computer built from the start as a ‘stored-program computer,’ an innovation that made it possible for computers to ‘remember’ their software and not have to be constantly reprogrammed every time a new problem was introduced” (Smith, 2007). Jean Jennings Bartik was a pioneer in software engineering. Her development of fundamental programming techniques such as subroutines and nesting are important concepts still in use today, without them computer code would be a lot more verbose. Also, during Bartik’s career she had the experience of working her way up the ladder; from being a simple computer calculating trajectories by hand to a project manager while developing the BINAC and
There are many different beginnings to the origins of computers. Their origins could be dated back more than two thousand years ago, depending on what a person means when they ask where the first computer came from. Most primitive computers were created for the purpose of running simple programs at best. (Daves Old Computers) However, the first ‘digital’ computer was created for the purposes of binary arithmetic, otherwise known as simple math. It was also created for regenerative memory, parallel processing, and separation of memory and computing functions. Built by John Vincent Atanasoff and Clifford Berry during 1937-1942, it was dubbed the Atanasoff Berry Computer (ABC).
When I was in middle school, I had totally no idea of what Computer Science is, but I was pretty proficient in using computers at that age. The only thing that I knew about Computer Science is that one of my aunts is in that field and that’s all, nor of my parents are in that major. Not until in High School that I got the sense of what programming is like. I was taught basic simple codings and I really enjoyed it and thought that the class was actually quite fun. But the class didn’t give me any sense of the important real-world applications of Computer Science. Not until recently as I am in the Computer Science major, I started to really have the real idea and to gain real passion for the field. Computer Science is not all about programming.
...ere are gears used to select which numbers you want. Though Charles Babbage will always be credited with making the first “true” computer, and Bill Gates with popularizing it, Blaise Pascal will always have a place among the first true innovator of the computer. There is even a programming language called Pascal or Object Pascal which is an early computer program.
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.
Imagine having a computer without running software. Computers would be slightly pointless without programs to run it. There would be no directions in the computer to tell it how to run, where to run, and what to do. A computer would have the ability to turn on, but a blank screen would be the only thing to appear on a monitor. I am sure that the question of "Who creates these programs?" has run through many minds in the past. These programs aid you in typing papers, connect you to the Internet, send information to other computers, or provide an interface for games that help to occupy your time. Computer programmers are the individuals that create and work with these programs. On a broad scale, computer programmers write the programs, test the programs, and then maintain the programs that millions of people use daily (Computer Programming 243-249). The every day duties of a computer programmer include investigating work requests from system analysts, understanding the problem and the desired resolution, choosing an appropriate approach, and planning an outcome that will tell the mechanism what to do to produce the desired results. Programmers must be experienced in high levels of mathematics, computer science, and programming languages. A programmer must also have experience with critical thinking, reading comprehension, and deductive reasoning. Programmers need to master these subjects, since they write in a language different from everyday English or French.
... deadlines. Anyone wishing to work in the field must be ready for long hours and maybe some uncomfortable working conditions. Some computer engineers work seventy to eighty hours a week. That's almost double of what the average occupation requires! It is also important to have the ability to grasp new ideas and adapt to them quickly. Somewhere in the world, at any
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.
There are disadvanges to being a programer. One being that you must risk eye damage with a computer screen every day.
The history of the computer dates back all the way to the prehistoric times. The first step towards the development of the computer, the abacus, was developed in Babylonia in 500 B.C. and functioned as a simple counting tool. It was not until thousands of years later that the first calculator was produced. In 1623, the first mechanical calculator was invented by Wilhelm Schikard, the “Calculating Clock,” as it was often referred to as, “performed it’s operations by wheels, which worked similar to a car’s odometer” (Evolution, 1). Still, there had not yet been anything invented that could even be characterized as a computer. Finally, in 1625 the slide rule was created becoming “the first analog computer of the modern ages” (Evolution, 1). One of the biggest breakthroughs came from by Blaise Pascal in 1642, who invented a mechanical calculator whose main function was adding and subtracting numbers. Years later, Gottfried Leibnez improved Pascal’s model by allowing it to also perform such operations as multiplying, dividing, taking the square root.
Choosing a career is very important in a person’s life. Over the past two decades, many professions have change significantly with the influx of technological developments. One needs to think about the things that interest them and what kind of lifestyle they want to have. Some things a person should think about are what qualifications are needed, what type of training is necessary, and the future need of the career they choose. Some other things to consider would be how much money they will make, what is the probability of advancement, and does the career satisfy their need for an enjoyable life.
... things that software engineers need to learn, if you do not learn these things you will be at a disadvantage and be limited to what you are capable of. The rapid growth will open new jobs for the upcoming generations of software engineering. Software engineering is a hard but rewarding career, but in the end it helps others accomplish things that would not be possible 50 years ago.
Computer programming can be a gateway job to many other interesting jobs. Programmers work in a wide variety of industries (Career Cruising). Programming can lead to making software for hospitals, banks, or even schools. But a very popular job for programmers is being part of a game development team. Programming can also lead to working for big companies like Google or Yahoo.
"programming" rules that the user must memorize, all ordinary arithmetic operations can be performed (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first “digital calculating machine”. It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal’s father who
