Computer engineering can be generalized as the summation of the electronic sciences by integrating certain components varying from microprocessors all the way to supercomputers. The development of the computer has shaped the way technology and science is viewed in different cultures around the world. The definition of what the archetype and function of a computer is a monitor, keyboard, processor and its other electronic components; however, that is not how things have always been. Computers have been around for quite some time and were developed over many years with contributions from philosophers, inventors, engineers, mathematicians, physicists, technicians, visionaries, and scholars. The first computers were simplistic mathematical calculating and eventually transformed into the computers that exist in the modern world. It has taken over 180 years for the computer to develop from an idea in Charles Babbage’s head into an actual computer developed today by many different companies. There was over a century of work to be done to make the computer into what we now use today. Before computers, people had to do calculations using such tool as a Chinese abacus or a slide rule to work out problems by hand. These small manually calculated devices over time evolved into the calculators developed in Japan in 1969, which were then used by Ted Hoff to produce a ‘soft-wired’ circuit, better known as a computer chip. Before and even more so after this invention, companies and government alike were delving into the science, designing computers that were specifically designed for a single task or few tasks which signaled the need for the computer. To differentiate these early computers, they were coded in separate binaries to perform their ... ... middle of paper ... ...passing its previous models, but still manages to be crippled by heating issues, which only sheds proof that even though we can engineer new devices that can surpass the performance of previous models, we are still limited by things such as overheating and power consumption. The early most-known contributors of computer science and engineering accomplished many things we still plainly recognize today: the production of a rudimentary Japanese calculator, MITS’ (Micro Instrumentation Telemetry Systems) production of the Altair which then lead to Paul Allen and Bill gates’ invention of the MOS-DOS operating system, to name a few. All of these discoveries and inventions are merely stepping stones that the founders of computer technology have crafted that lead towards the future, which surely will rapidly progress into an ever expanding world of computer engineering.
Computer hardware engineers research, develop, and test computer systems and components such as processors, circuit boards, memory devices, and many more (Bureau of Labor Statistics). They design new computer hardware, create blueprints of computer equipment to be built. Test the completed models of the computer hardware that they design. Update existing equipment so that it will work will new software. Oversee the manufacturing process for the computer hardware. Maintain knowledge of computer engineering trends and new technology(Bureau of Labor Statistics).
Computers are a magnificent feat of technology. They have grown from simple calculators to machines with many functions and abilities. Computers have become so common that almost every home has at least one computer, and schools find them a good source for information and education for their students (Hafner, Katie, unknown). Computers have created new careers and eliminated others and have left a huge impact on our society. The invention of the computer has greatly affected the arts, the business world, and society and history in many different areas, but to understand how great these changes are, it is necessary to take a look at the origins of the computer.
stimulate me as well as challenge me? The second being: Is there a way of
First off let’s get something straight. When I refer to computers in this essay I am not referring only to the microprocessor sitting on your desk but to microprocessors that control robots of various structure.
Although the majority of people cannot imagine life without computers, they owe their gratitude toward an algorithm machine developed seventy to eighty years ago. Although the enormous size and primitive form of the object might appear completely unrelated to modern technology, its importance cannot be over-stated. Not only did the Turing Machine help the Allies win World War II, but it also laid the foundation for all computers that are in use today. The machine also helped its creator, Alan Turing, to design more advanced devices that still cause discussion and controversy today. The Turing Machine serves as a testament to the ingenuity of its creator, the potential of technology, and the glory of innovation.
The career path that I have chosen was computer engineering. I chose this career because I have spent my entire life around computers, and had experience working with programming languages and the hardware. I gained further interest in computer engineering after I took an AP Computer Science class in high school. In the class I was required to use programming languages to create different types of programs which challenged me. This inspired me to want to learn even more about the computer science field and to learn more java script and programming languages.
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.

Prior to the revolution in technology that was microprocessors, making a computer was a large task for any manufacturer. Computers used to be built solely on discrete, or individual, transistors soldered together. Microprocessors act as the brain of a computer, doing all mathematics. Depending on how powerful the machine was intended to be, this could take weeks or even months to produce with individual components. This laborious task put the cost of a computer beyond the reach of any regular person. Computers before lithographic technology were massive and were mostly used in lab scenarios (Brain 1).
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.
My interest in Computers dates back to early days of my high school. The field of CS has always fascinated me. The reason for choosing CS stream was not a hasty decision. My interest started developing in the early stage of my life, when I studied about the invention of computers. The transformation from the large size to small palmtops enticed me to know about the factors responsible for making computers, also the electronic gadgets so small. I was quite impressed after seeing a small chip for the first time in my school days, especially after I learnt that it contained more than 1000 transistors, “integrated circuits”.
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.
Gates and Allen soon got many opportunities to prove their computer skills. In 1972, they started their own company called 'Traf-O-Data.' They developed a portable computer that allowed them t...
If the nineteenth century was an era of the Industrial revolution in Europe, I would say that computers and Information Technology have dominated since the twentieth century. The world today is a void without computers, be it healthcare, commerce or any other field, the industry won’t thrive without Information Technology and Computer Science. This ever-growing field of technology has aroused interest in me since my childhood. After my twelfth grade, the inherent ardor I held for Computer Science motivated me to do a bachelors degree in Information Technology. Programming and Math, a paragon of logic and reasoning, have always been my favorite subjects since childhood.
computer. The electronic computer has been around for over a half-century, but its ancestors have been around for 2000 years. However, only in the last 40 years has it changed the American society. From the first wooden abacus to the latest high-speed microprocessor, the computer has changed nearly every aspect of people’s lives for the
