The topics, methods and differences between computing disciplines.

What is the computing discipline??? According to my research, it is the systematic study of algorithmic processes that describe and transform information: their theory analysis, design, efficiency, implementation, and application. There are five major parts under computing disciplines such as information system (IS), cognitive science (CgS), computer science (CS), software engineering (SE) and computer engineering (CE).

Information system:                : It is concerned with the information that the computer system can provide to aid the company or organization in defining and achieving its goals in an effective and efficient ways. This is especially computing in an organizational context typically in business field. This discipline’s perspective on information technology emphasizes information and view technology as an instrument for generating, processing and distribution information. Besides, IS specialists must understand both technical and organizational factors because they must have to determine what kind of information is needed for this organization and to get competitive advantages.

Cognitive science:                   : CgS is the interdisciplinary study of intelligence in humans and machines. It is also similar to Psychology but with more related with computation and experience with the wider range of analysis techniques. Actually, cognitive science is more related with computer science but with greater emphasis on cognition and sociocultural factors. Currently, the most frequent job placements in the computer industries are cognitive engineers and it will become more and more develop in the future days.  

Computer science:                   : Currently the most popular of the computing disciplines have a tendency to be relatively extensive and with an prominence on the underlying science aspects. It is more concerned with the developments in in robotics, computer vision, intelligent systems, bioinformatics, and other exciting areas. Especially, computer science spans the range from theory through programming.  Progress in the CS areas of networking, database, and human-computer-interface enabled the development of the World Wide Web. Now CS researchers are working with scientists from other fields to make robots become practical and intelligent aides, to use databases to create new knowledge, and to use computers to help decipher the secrets of our DNA.

Software engineering:                         : It Focuses on large-scale software systems such that employs certain ideas from the world of engineering in building reliable software systems. It is the discipline of developing and maintaining software systems that behave reliably and efficiently, are affordable to develop and maintain, and satisfy all the requirements that customers have defined for them. Software engineering is different in character from other engineering disciplines due to both the intangible nature of software and the discontinuous nature of software operation. It seeks to integrate the principles of mathematics and computer science with the engineering practices developed for tangible, physical artifacts.

Computer engineering:                        : Computer engineering is concerned with the design and construction of computers and computer-based systems. It involves the study of hardware, software, communications, and the interaction among them. Its curriculum focuses on the theories, principles, and practices of traditional electrical engineering and mathematics and applies them to the problems of designing computers and computer-based devices. . For example, devices such as cell phones, digital audio players, digital video recorders, alarm systems, x-ray machines, and laser surgical tools all require integration of hardware and embedded software and all are the result of computer engineering.

Can I live without internet connection for a day, a month or a year?

Although internet is excluded in basic needs for all the human beings, we are using it widely in all over the world. I have never imagined before how my life will be affected without internet connection for a day because we are using internet connection easily in every day. Therefore, I didn’t realize the value of internet connection. But I am sure that if I cannot use internet connection for one day, I will really be in the trouble because I am very depend on the internet for my academic study rather than studying from book. Personally, I like to work with the computer rather than writing the notes down in the book. Moreover, I think that if we want to do self-study, using internet is more effective than studying from the books. The reason is that on internet, there are so many resources that we can explore such as we have YouTube for the video presentation, there are so many online tutorial or test that we can sit the exam through online, and so on. These kinds of things can never be done easily without internet connection. Besides, there are a lot of social websites that we can communicate with other people through online. For the people like me (the people who are away from our hometown), we need to communicate with our family through the internet effectively rather than talking on the phone because it is too expensive. Now, we have internet and we can call to our family without any charges. As to conclude, internet connection is very important for me and to be honest, I will find a lot of difficulties without internet connection for a day.
