Computer Science Vs Information Technology

Computer Science Vs Information Technology

We are in the computer world right now, and everyone in this world needs technology in their lives. Not only computer scientist or information technologist uses computer nowadays. I see people who did not study any of these fields become web developers, information security analysts, etc. Before choosing any of these fields, you need to know which one works for you, and that is what we will like to know. In this article, we will get to see the difference between Computer Science and Information Technology. We have come across the two fields, and yes, they are essential in this world because I don’t see any organization that wouldn’t need any of them.

Computer science and Information Technology are so crucial that things we use in our day-to-day lives are designed (computer scientist) and tested(information technologist) by them before it gets to the market. Because we are in a Technology world right now, professionals In science, technology, engineering, and mathematics (STEM) are in high demand. Everyone needs them to d,o things or the other for them. Now what I will say is that before anyone has decided to study any of these fields, they must have known the basics in each of them. Computer science and Information Technology require focus with brains. These fields are not like any other course you know, and I know that you must be confused on which one to pick but not to worry because at the end of this article you will understand the two fields and their Differences will help you make a better choice.

We all know what a computer is, but I will just define it for clarification purposes. A COMPUTER is a machine that can solve problems by accepting data, performing certain operations, and presenting the result of all those operations under the direction of detailed step by step instructions.


Computer science is the study of the operating principles of computers, computer programming languages, and algorithms for solving theoretical and practical problems. It involves the development and use of devices for processing information. “According to  Advance English Dictionary, computer science is the branch of engineering science that studies (with the aid of computers) computable processes and structures. “Wikipedia also defined computer science as the study of algorithmic processes, computational machines, and computation itself). Wikipedia also states that computer science deals with the theoretical foundations of information, algorithms, and the architectures of its computation and practical techniques for their application.

Computer scientist uses mathematical algorithm and codes and software and systems. Computer scientists master programming skills to understand computer processes that can be applied to the systems. Examples of computer scientists’ career paths are web development, computer system engineering, computer programming, artificial intelligence, game design, and information security networks. Computer science has both practical and theoretical parts. Computer science’s practical aspect has to do with programming languages, while computer science’s theoretical aspect deals with computational theory. Several computer scientists have argued about the different patterns involved in computer science. “Peter Wegner” said that computer science consists of science, technology, and mathematics. While “Peter Denning” said that computer science consists of theory, abstraction, and design. Essential areas in computer science include

  • Database system
  • Networking
  • Communication
  • Artificial intelligence
  • Software engineering
  • Computer graphics
  • Operating system
  • Programming

Yes, they say that computer science is mainly practical and theoretical. Still, I will say that computer science is mainly just practical because it requires codes using algorithms. After all, coding is the major thing computer scientist do. You won’t see a computer scientist going about typing documents, and not that they can’t do it, but that is not what computer science is all about. Computer science is all about programming and the rest. Computer scientists develop programs and design systems. Some of these designed products and services include laptops, mobile phones, Gps unit, and scientific calculators. Search engines like google, bing, Yandex, swisscows, gibiru, Windows operating systems, Microsoft Office suites, Wireless fidelity (Wi-Fi) network.

Computer scientist program operating systems like windows 10, windows 7, and Linux. They also develop programming languages such as Java, HTML, python, oracle, COBOL, c++ vb,c#, swift, scala, go, ruby even artificial intelligence. Computer science develops application software like ms word, mobile apps, etc. Computer scientists also build systems and software used by banks, airlines portals and develop firewalls, antivirus for systems such as Norton and McAfee. Students that want to go into computer science must know the computation and problem-solving process.


Information Technology has to do with networks, software; systems use to send, store and retrieve data. “ According to English Dictionary, information technology is the branch of engineering that deals with the use of computers and telecommunications to retrieve and store and transmit information). “Wikipedia defined information technology as using computers to store, retrieve, transmit and manipulate data IInformation Technologyaddressess the business side of computer science. Information Technology protects, store, process, transmit and retrieve data. Networks, databases, servers are also added to the list of information Technology. Information technologists identify different computing systems to solve human and business problems. They keep Technology, whether the business uses it up today, for easier use. Information Technologist install, run, maintain and test programs developed by a computer scientist. Some professional Technologists can also develop software, mobile application software such as Uber and the rest. Information Technology involves installing, organizing, and maintenance of computer systems. Information Technologists apply all computer science principles. Some career paths are chosen by information Technologists include:

  • Computer Networks Architect
  • Information Security Analyst
  • Servers
  • IT Support Specialist


There is not much difference between computer science and Information Technology. No wonder these two fields can work in the same industry. Even people without qualifications or a degree in any of these fields have come across a computer because computers and other gadgets now dominate the world. Secretaries, cashiers, and receptionists are perfect examples of people who use the computer.  Differences between them are listed below.

  • Computer science involves programming and algorithms, while information technology consists of designing and operating networks.
  • Computer science is an independent course that says that they can work on their own and don’t need a team before they can accomplish a goal. In contrast, information technology isn’t independent because they usually work in teams and work directly with their clients.
  • Information Technologist works only in a business environment while a computer scientist works in a much wider environment range.
  • When it comes to academics, you ought to know that information technology is industry-oriented, whereas computer science is research-oriented.
  • Computer scientists design software while information technologists test and apply them.
  • Computer scientist look at the why behind the operating system and the computer program, while an information Technologist look at the how behind the operating system and how it can be used to solve business problems.
  • Computer scientist uses their skills in theories and mathematics to make information technology possible. In contrast, information technologist uses their skills to communicate with businesses to achieve their needs using Technology.
  • Computer science is more technical, and information technology is more on the business side.


They are different; that is how their skills too are different. Here we will know the kind of skill they should possess:


  • Communication skill.
