What is the Difference between Information Technology and Computer Science?
There is an overlap in the two fields, but there are some major differences, and you might be drawn to one or the other because of your personality and aptitudes. Computer science is focused entirely on efficiently programming computers using mathematical algorithms.
Jobs in computer science often require independent work. An IT career involves installing, organizing, and maintaining computer systems as well as designing and operating networks and databases. Information technology may appeal more to people who prefer to work in teams, or directly with clients and customers. It is as though computer science creates building blocks, and IT stacks those blocks up to form buildings, bridges, and other structures necessary for a city to function.
That includes businesses, health systems, recreation and art, and other elements of society that have become digitalized. IT professionals typically work in a business environment installing internal networks and computer systems and perhaps programming.
Computer scientists work in a wider range of environments, ranging from businesses to universities to video game design companies. Both of these careers have excellent growth potential and high salaries, with software developers somewhat ahead of IT professionals in earnings. A computer science degree gives students a rigorous education in discrete mathematics and computer science theory. Most CS graduates go on to become software developers or web programmers, and those who continue on to graduate-level schooling have the chance to do research or work in more specialized roles, such as advanced artificial intelligence programming.
Follow that out further to, say, , we will have multiplied the intelligence, the human biological machine intelligence of our civilization a billion-fold. With a four-year CS degree, students can find employment as programmers, software engineers, or IT professionals. However, to become a software developer, graduates usually must teach themselves quite a bit of programming on their own. This particular job, according to the BLS, is predicted to grow by 11 percent in the next ten years.
This involves using artistic design principles and creating links to related information. People who work in computer science designing and building computers must have project management skills that include time management and the ability to see tasks through to completion.
Being able to recognize and attend to small details is vital as well. For instance, one job in information technology is a computer support technician. For that position, people must have communication and customer service skills. Both fields require a knowledge of programming languages, though more is needed for computer science jobs. Indeed, for some of these jobs, experience and hands-on learning are as important as the college coursework.
Still, the general rule is that job applicants will need at least an undergraduate degree in either computer science or information technology. People enrolling in these programs should be detail-oriented and have an aptitude for math because mathematics is the language of computing. They must also be adept problem-solvers with critical thinking skills.
Graduate degrees in computer science and information technology go by many names. These degrees all have the same courses in fundamentals such as applied data analytics and advanced mathematics plus specialization courses.
There are graduate certificates, as well, in things like advanced information technology and cybercrime investigation. These certificates are proof of advanced study in these areas of specialization and add to a resume. With as rapidly as advances in modern technology take place, it is important to keep up with the latest trends and information in the fields of computer science and information technology. The following journals and blogs are popular among computer science and IT professionals:.
Annual Conferences are also a good way to stay informed. Here are some popular annual IT and computer science conferences:. In addition to certifications offered by tech schools and universities, professional certifications help to make job candidates stand out to possible employers. Though there is no national organization that licenses or certifies computer scientists or information technology specialists, there are two basic types of professional certifications.
One is the vendor-specific certificate and the other is the vendor-neutral Certificate. The vendor-specific certificate is one that is awarded by a computer tech company such as Microsoft or Cisco Systems. These certificate programs teach skills in using the products of the sponsoring company. They encourage businesses to use their products, platforms, and processes by offering the courses. The result is that some companies rely solely on one brand of products and job applicants must have expertise in those products.
So, a company that uses Microsoft programs would require their employees to have or to obtain Microsoft certification in those platforms or products. Cisco Systems offers the following certifications:. A vendor-neutral certificate is one that is offered by an organization and does not promote any one brand.
That makes it possible for anyone in the computer sciences or information technology field to gain expertise without being restricted to one employer or system. Entry-level certificates typically do not have any prerequisite courses. Those intended for experienced professionals may require the individual to have taken certain coursework or to have a minimum level of work experience. These certificates generally also require the candidate to pass an exam. The certificates take from three-to-twelve months to earn.
Some are self-paced and self-directed online, and some are presented in a five-day online or face-to-face program. Software developer jobs are projected to grow 21 percent by , well above average. According to the Bureau of Labor Statistics, the highest-paying employer of computer scientists is software publishers. These companies are often the developers as well. They include providers of operating systems, data refining technologies, educational programming, and even gaming.
The demand for programmers is declining. Database administrator jobs are expected to increase by nine percent. The job demand is expected to increase by 13 percent, which is much higher than the BLS average of five-to-eight percent. With a two- or four-year IT degree, graduates can find work in a number of occupations, including information security, network architecture, database administration, systems administration, and computer support.
However, some of these jobs require advanced computer science and programming knowledge, so graduates must enroll in specialized programs or take elective courses. For example, information security requires knowledge of discrete math and algorithms, and database administration requires knowledge of programming. To put the job simply, they research and experiment with systems to make the best and most cost-effective use of programming to meet organizational goals.
Consultation is generally billed by day, by consultant. Many IT consultants work for consulting firms, but some are independent contractors.
It is like a virtual closet that must be kept organized and cleaned. Cloud architects do that job. The position involves a basic knowledge of operating systems and networking, programming languages, and security. The analysis of that information is often used in criminal investigations.
He designs software for specific machines and monitors the computers for security breaches like cyber-attacks and viruses, malware, and unauthorized data mining. Considering these two areas of technology as one entity computer-based professions , where is the best place to look for a job?
Forbes Magazine says Washington DC is the top state for computer-related jobs. It cites the number of defense contractors and government jobs as the reason. California comes in third on the list. New York City recently had 8, job listings on Indeed. Some of the major entries with high salaries were for educators in universities. Surprisingly, the list of cities with the highest pay for these jobs is different.
The highest-paying state is Washington, followed by California, Colorado, Virginia, and Massachusetts. Source: Forbes. It is certain that these types of jobs will be more in demand as the world becomes more technology-oriented. Milestones in computer technology are being reached quickly. As a matter of fact, 20 percent of all vacuums in the world are robotic, according to TechCrunch. Most large hospitals have robotic surgical instruments. Additionally, the health records of most patients are now digital.
A blog at Cisco. A zettabyte is an impossibly high benchmark, conceivable to mathematicians if no one else. All of these things point to a future that is increasingly data-driven.
While information technology and computer science degrees can lead to similar jobs, the differences between the two are quite pronounced. Information technology professionals should enjoy installing computer systems, using software, and maintaining networks and databases, while computer scientists should enjoy mathematics and software design. In general, the relationship between information technology and computer science is quite close and interdependent. Degree programs feature many of the same core courses and differ only in the direction taken by electives.
Salary is commensurate, though computer science tends to have a slight edge. The BLS and many business and tech resources lump computer science and information technology jobs together in their statistics. So, in the consideration of I.
