...Computer science is challenging, and yet dynamic. It requires people in the field to keep learning and pushing the limit. That fast-pacing innovation of technology never stops amazing me, which excites my innate curiosity even more. I, however, had never thought about pursuing computer science as a career until I took an AP Computer Science class in my senior year. It sparked my interest and changed my thoughts after seeing what I could do with some simple line of codes. Despite many countless times staring into the monitor trying to figure out how to solve a problem, those “Aha” moments were more precious and exciting for me. For every minute like that, I was exhilarating and smiled as if I have just won an Olympics’ gold medal in a 100-meter racing swim lap. It fed my hunger for exploration to see what else I could do, maybe something beyond my imagination. Computer science gradually became my hobby in my senior year. I searched many online resources to finally find CodingBat, which allowed me to expand my Java knowledge.These experiences slowly pulled me into the course of a new career, computer science, and at The University of North Carolina at Greensboro pursuing a degree in computer science can provide me knowledge and skills to bring change to people’s daily lives starting from mobile application. I want to be a part of this evolution of technology and I hope to meet other creative, friendly, and ambitious people. My dream is to start my own business partnership during...

...From an early age I’ve always been deeply interested in computing. It was my dad, introducing me to the computer systems at his work place that first sparked this interest. I can always remember the feeling of wanting to know just how computers worked, why they worked and what else they could do. This interest never left me, only growing more profound and passionate with every new discovery I made. From communicating with an artificial intelligence to seeing the wonders of the Internet for the first time, computers have left me fascinated with just how much power yet mystery they hold. My studies have all helped me to develop my understanding of the subject. While Computing has given me a greater insight into the business aspects of the computer industry, Physics have helped to improve my analytical and evaluative skills. My interest in computing has not been restricted to the classroom. Within the last few months I’ve used the knowledge that I’ve gained over the past twelve years to set up my own computer related business. This has given me a totally new perspective on how certain things function, and how business operates. The writing of a business plan was a totally alien experience for me, but over the course of three months I researched and planned, and finally when the plan was complete I was rewarded with the satisfaction of knowing that I had completed something that most people would never have the chance to do especially at my age. As well as spending time both...

...The Fluidity of Computer Science. Gender Norms & Racial Bias in the Study of the Modern "Computer Science" Computer science or computing science designates the scientific and mathematical approach in computing. A computer scientist is a scientist who specialises in the theory of computation and the design of computers. Its subfields can be divided into practical techniques for its implementation and application in computer systems and purely theoretical areas. Some, such as computational complexity theory, which studies fundamental properties of computational problems, are highly abstract, while others, such as computer graphics, emphasize real-world applications. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to description of computations, while the study of computer programming itself investigates various aspects of the use of programming languages and complex systems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans. Computer science deals with the theoretical foundations of information, computation, and with practical techniques for their implementation and application. History The earliest foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks such as the abacus have existed since antiquity...

...Computer science is the scientific and practical approach to computation and its applications. It is the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information, whether such information is encoded as bits in a computer memory or transcribed in genes and protein structures in a biological cell.[1] A computer scientist specializes in the theory of computation and the design of computational systems.[2] Its subfields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory (which explores the fundamental properties of Computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications. Still other fields focus on the challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, whilst the study of computer programming itself investigates various aspects of the use of programming language and complex systems. Human-computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans. The earliest foundations of what would become computer science predate the invention of the modern digital computer. Machines for...

...History of Computer Science Name: Kamyll Dawn Cocon Course, Yr. & Sec.: BSMT 1-D REACTION PAPER The topic of the video which is about the history of computer was kind of interesting since it high lightened our mind about where the computer had really came from. Not only have that, it also made us understand how the computers of today became very wonderful and powerful. Before, computers only existed in the imagination of humans and were believed that creating such monstrous device was impossible. It was a huge leap in the field of computer during the 19th century when Charles Babbage developed the 1st modern computer called the difference machine. The most advantageous feature of this machine is that it reflected Babbage’s attitude of being a perfectionist. Although his work was not finished, the detailed text that was written by Ada was significant in modifying his versions and for documentary purposes of his work. The rapid increase of the American population, on the other hand, triggered the development of a machine that will help the census tabulate such population very fast. Hermin Horrith’s occupation was very helpful to the development of this machine since he used business to gain money to revise his machine which had later evolved into the international business machine. Although war causes devastation to the environment as well as the people involved, it also had contributed to the development of computers, which is the birth of ENIAC, the first large-scale...
