What Does a Computer Scientist Do?
As the name implies, a computer scientist is actually a scientist. Rather than working with lab equipment, however, they use algorithms and math to find ways to transfer information. A computer scientist trades in beakers and test tubes for software and operating systems like Windows or Mac OS. Computer scientists also work with code and various programming languages. They’re able to understand computers and concepts in software design and development to the point where they can actually create a custom program or operating system and “tell it” what to do.
What Does a Computer Engineer Do?
While a computer scientist works with systems and software, a computer engineer works with the actual equipment that makes the computer function, such as the circuit board, router, and microchips. A computer science engineer is responsible for making these components work together versus manipulating the programs and software to make a system work a specific way. While a computer engineer may have a background or degree in engineering, they can benefit from a background in computer science, as they often work with hardware and software integrations.
What Does an Information Technologist Do?
While a computer scientist builds the programs and software and a computer engineer builds the systems and components, an IT professional installs and helps to maintain and improve computer systems and networks. IT professionals can work in various industries and help maintain the computers and networks that help a business or company run smoothly. Just about every company, from startups to large corporations, relies on an IT professional for any computer or technology-related issues.
While the other two vocations rely heavily on math, engineering, and algorithms, information technology requires knowledge of database design, but may also require soft skills since many IT professionals work with clients.
Key Differences Computer Science vs Information Technology
understanding the differences between Computer Science (CS) and Information Technology (IT) is crucial for choosing the right career path. Computer Science is a broad field that delves into the theoretical foundations of computing. It covers a wide range of topics, including algorithms, data structures, software development, and hardware architecture. The scope of CS extends to specialized areas such as artificial intelligence, machine learning, cybersecurity, and computational theory. The primary focus of Computer Science is to innovate and advance computational methods, creating new technologies and solving complex technical problems. This field requires a strong background in mathematics and logic, emphasizing problem-solving and abstract thinking.
On the other hand, Information Technology is more specialized and application-focused, dealing with the practical aspects of technology in business and organizational settings. IT encompasses the management and support of IT infrastructure, networks, databases, and systems. The main focus of IT is on the implementation, support, and maintenance of technology systems. This includes network administration, cybersecurity, systems maintenance, and IT support, ensuring that technology systems are reliable, secure, and efficient. IT professionals often work closely with end-users to optimize the use of technology and address technical issues within organizations.
