You Know? What is Computer Science?


Computer science is a discipline that spans theory and practice. It requires thinking both in abstract terms and in concrete terms. The practical side of computing can be seen everywhere. Nowadays, practically everyone is a computer user, and many people are even computer programmers. Getting computers to do what you want them to do requires intensive hands-on experience. But computer science can be seen on a higher level, as a science of problem solving. Computer scientists must be adept at modeling and analyzing problems. They must also be able to design solutions and verify that they are correct. Problem solving requires precision, creativity, and careful reasoning.

Computer science also has strong connections to other disciplines. Many problems in science, engineering, health care, business, and other areas can be solved effectively with computers, but finding a solution requires both computer science expertise and knowledge of the particular application domain. Thus, computer scientists often become proficient in other subjects.

Finally, computer science has a wide range of specialties. These include computer architecture, software systems, graphics, artificial intelligence, computational science, and software engineering. Drawing from a common core of computer science knowledge, each specialty area focuses on particular challenges.

Computer Science is practiced by mathematicians, scientists and engineers. Mathematics, the origins of Computer Science, provides reason and logic. Science provides the methodology for learning and refinement. Engineering provides the techniques for building hardware and software.
The City College of New York- Computer Science deals with information; its efficient representation and transformation, its communication and security; its storage, retrieval, analysis and display.

Another definition from

Computer Science: The Profession

Computer science is a discipline that involves the understanding and design of computers and computational processes. In its most general form it is concerned with the understanding of information transfer and transformation. Particular interest is placed on making processes efficient and endowing them with some form of intelligence. The discipline ranges from theoretical studies of algorithms to practical problems of implementation in terms of computational hardware and software.

A central focus is on processes for handling and manipulating information. Thus, the discipline spans both advancing the fundamental understanding of algorithms and information processes in general as well as the practical design of efficient reliable software and hardware to meet given specifications. Computer science is a young discipline that is evolving rapidly from its beginnings in the 1940’s. As such it includes theoretical studies, experimental methods, and engineering design all in one discipline. This differs radically from most physical sciences that separate the understanding and advancement of the science from the applications of the science in fields of engineering design and implementation. In computer science there is an inherent intermingling of the theoretical concepts of computability and algorithmic efficiency with the modern practical advancements in electronics that continue to stimulate advances in the discipline. It is this close interaction of the theoretical and design aspects of the field that binds them together into a single discipline.

Because of the rapid evolution it is difficult to provide a complete list of computer science areas. Yet it is clear that some of the crucial areas are theory, algorithms and data structures, programming methodology and languages, and computer elements and architecture. Other areas include software engineering, artificial intelligence, computer networking and communication, database systems, parallel computation, distributed computation, computer-human interaction, computer graphics, operating systems, and numerical and symbolic computation.

A professional computer scientist must have a firm foundation in the crucial areas of the field and will most likely have an in-depth knowledge in one or more of the other areas of the discipline, depending upon the person’s particular area of practice. Thus, a well educated computer scientist should be able to apply the fundamental concepts and techniques of computation, algorithms, and computer design to a specific design problem. The work includes detailing of specifications, analysis of the problem, and provides a design that functions as desired, has satisfactory performance, is reliable and maintainable, and meets desired cost criteria. Clearly, the computer scientist must not only have sufficient training in the computer science areas to be able to accomplish such tasks, but must also have a firm understanding in areas of mathematics and science, as well as a broad education in liberal studies to provide a basis for understanding the societal implications of the work being performed.
From Mississippi State University

Computer Science is the study of principles, applications, and technologies of computing and computers. It involves the study of data and data structures and the algorithms to process these structures; of principles of computer architecture-both hardware and software; of problem-solving and design methodologies; of computer-related topics such as numerical analysis, operations research, and artificial intelligence; and of language design, structure, and translation technique. Computer Science provides a foundation of knowledge for students with career objectives in a wide range of computing and computer-related professions.

From the University of Missouri – Rolla

Computer Science is concerned with information in much the same sense that physics is concerned with energy; it is devoted to the representation, storage, manipulation and presentation of information.

Computer Science is concerned with “the study of symbol-manipulating machines, with communication between man and machine and with the application of these machines”.
Major areas of Computer Science include:

  1. Operating Systems–concerned with the development and structure of complex programs which facilitate man-machine communications.
  2. Computational Science–the analysis of numerical methods for solving mathematical problems with a computer.
  3. Programming Languages–the study of the design and properties of languages by which humans communicate with computers.
  4. Architecture–the study and use of mathematical logic to design electronic circuits.
  5. Intelligent Systems–concerned with means by which computers may perform tasks which might be characterized as “intelligent” if performed by humans.
  6. Automata Theory–an abstract study of computers and their capabilities.
  7. Information Storage and Retrieval–the study of methods for storing a vast amount of data in a computer and methods for searching and retrieving this data.
  8. Software Engineering–the study of tools and techniques for software design, development, testing and maintenance.

Second Opinion Malware Scanner

If your child is not feeling well and you suspect he or she has a virus infection you’re going to visit your doctor. But what do you do when the doctor tells you that he cannot find anything but your child still does not feel very well? Of course, you go to visit another doctor for a second opinion.

This is the same what HitmanPro does for your computer. HitmanPro is a second opinion scanner, designed to rescue your computer from malware (viruses, trojans, rootkits, etc.) that have infected your computer despite all the security measures you have taken (such as anti virus software, firewalls, etc.).

Why A Second Opinion?

Research shows that computers are still run a chance of getting infected because the existing anti virus program is not giving you a 100% protection. “32% of computers infected, despite presence of anti virus program.”

Just relying on a single vendor is not sufficient to completely protect you. You do need a second source to make sure you are secure. But in most cases, installing a second anti virus program is not a viable solution. Two programs are effecting the performance of the computer dramatically, and sometimes even conflict causing the computer to crash.

HitmanPro is designed to work alongside existing security programs without any conflicts. It scans the computer quickly (less than 5 minutes) and does not slow down the computer (except for the few minutes it is scanning). HitmanPro does not need to be installed. It can be run straight from a USB flash drive, a CD/DVD, local or network attached hard drive.

HitmanPro offers you a Free Scan for a second opinion. It is designed to check if your security measures work. If nothing is found (and we sincerely hope so), then you will never need a license. When a virus is found, then you will receive a free 30-day license to remove the threat.

Behavioural Scan

SurfRight has done an extensive research of malware files to determine the common characteristics (behaviour) of malware. The HitmanPro client uses this research in its Behavioural Scan, when it scans the computer for virus activities or suspicous files that have the characteristics of malware.

Scan Cloud

For the files that are classified as suspicious, the HitmanPro client sends a request to the Scan Cloud for confirmation if these files are indeed malicious. The Scan Cloud is a cluster of multiple computers, residing on the Internet. The Scan Cloud will respond to this request with the answer:
  • Safe
  • Malicious
  • Unknown
When the file is unknown, the HitmanPro client uploads the file to the Scan Cloud where the file is scanned using the anti virus programs of 5 different vendors. Each of these anti virus programs analyzes the file and responds with “safe” or “malicious”.

Malware Removal

When the file is classified as malicious by the Scan Cloud, the HitmanPro client is placing the infection into quarantine. Various techniques ensure that all infections are completely removed without false positives.

Who Should Use HitmanPro?

  • Computer users can use the Free Scan of HitmanPro as a quick check (less than 5 minutes) to ensure that the existing anti virus program has not missed a threat.
  • Help Desk and Support organizations can use the Free Scan of HitmanPro as a quick check for viruses and other malware. It can be run from USB or CD/DVD. No installation is required.
  • Website owners can offer the Free Scan of HitmanPro as a service to visitors for a quick second opinion.
