What Is Computer Information Technology?
The term 鈥渋nformation technology鈥� is used often and sounds broad, but what does it actually mean and why is it important?
Computer information technology, or IT, is a relatively new professional field that emerged in the 1990s when computers became the basic tools used for work and everyday life. The rise in computer use introduced the need for professionals that could develop and maintain the new technological infrastructure. 鈥淐omputer information technology鈥� is often used to refer to technical support, but it鈥檚 become much more than that.
While IT deals with the development, maintenance, and use of computer systems and networks, it encompasses a wide variety of tech-based disciplines that handle information and data. Security and communication are important elements of the technology industry, especially as systems become more public and technology continues to evolve.
Why Is Information Technology Important?
Technology impacts nearly every aspect of daily life, including how people communicate, learn, socialize, work, bank, and more. IT professionals ensure that this technology鈥攊ncluding its underlying networks and software鈥攐perates effectively.
Thanks to IT professionals, organizations and individuals enjoy better connections through faster, more accessible communication and increased productivity through easier access to information. From finance to farming, nearly every industry relies on information technology, and this dependence is only going to become stronger.
What Areas Does Information Technology Include?
IT comprises many career paths and disciplines, but the following are the five main professional areas of IT:
- Administration: handling the daily operations and deployment of software upgrades, security, and data management.
- Support: answering questions and troubleshooting problems.听
- Applications: delivering critical third-party business capabilities and services.
- Compliance: securing and monitoring access to business data and applications to ensure they鈥檙e used according to business governance policies that meet regulatory requirements.
Cybersecurity: developing and utilizing software that secures computer-based systems and keeps digital assets safe.
Types of Information Technology
Obvious examples of IT include computers, networks, and software. But IT also involves anything related to computing technology and its distribution, including online shopping, streaming movies and shows, and social media platforms.
There are many other examples of IT-enabled innovation, the most notable being artificial intelligence (AI) and machine learning. AI can simulate certain characteristics of human intelligence. It鈥檚 used in problem-solving, speech recognition, planning, learning, and more. It can even provide suggestions based on previous searches, online activities, and purchases.
In the healthcare industry, AI is helping to provide safer and more efficient care for patients everywhere. It鈥檚 being used in various treatments for patients as well as surgical operations. It also has a presence in electronic health records to store and learn from data, in scheduling services for doctors and patients, and in the many technological devices that doctors use daily.
In today鈥檚 classrooms, teachers and students can utilize AI for educational purposes such as plagiarism checkers, citation finders, research archives, and more.
Machine learning is another example of IT innovation. It鈥檚 based around the idea that humans can give machines data and allow them to learn for themselves. Social media platforms utilize machine learning algorithms and intelligence to serve up relevant ads, display content that matches user preferences, and more. Machine learning also helps autonomous technology to work properly鈥攖hink self-driving cars, for example. Cars can now learn from their surroundings, recognize how traffic signs impact their routes, and observe pedestrians and other vehicles.
Careers in Computer Information Technology
The number of careers in the IT industry is constantly increasing thanks to continuous innovation and the growing demand for able IT experts. Some of the most common careers include the following:
- Web developer. Web developers are the primary architects of the websites and web apps that people around the world use in their everyday lives.
- Information security analyst. These professionals are at the forefront of modern cybersecurity. They help protect digital data and networks from hackers, malware, and other cyber threats.
- Computer support specialist. When users face technical issues or need proper network administration, they turn to computer support specialists for assistance.
- Computer programmer. Programmers write, edit, and debug code for all kinds of computer software. They may be involved in web development, software development, or software engineering.
- Computer research scientist. A computer research scientist finds new ways to implement computing technology through rigorous data analysis and mathematical modeling.
Many IT careers also explore advancements in AI, cybersecurity measures, and automation.
What鈥檚 the Difference Between Software and Hardware?
Think of hardware as any part of a computer that鈥檚 physical (like a keyboard, hard drive, or monitor). Software includes digital elements such as programs, apps, photo editors, and web browsers. Simply put, software tells hardware what to do and hardware executes those directions. Hardware and software serve very different purposes but rely on each other in order to function.
Software-based jobs in IT are about developing applications or programs and include the following:
- Software engineer
- Software developer
- Computer programmer
- Web developer
- Application developer
Hardware-based IT jobs concern working with computer networks, equipment, and systems and include any of the following:
- Computer operator听
- Computer support specialist听
- Hardware engineer
- Cloud architect
- Computer network architect
What鈥檚 the Difference Between Information Technology and Computer Science?
While the two fields often overlap, there are some key differences to know, especially if you鈥檙e interested in pursuing a tech career.
Information technology focuses more heavily on the practical operation of computers, networks, and software systems so that individuals or organizations can do their work efficiently.
Computer science deals with more abstract programming and mathematical algorithms and is often strictly computer based.
IT professionals are more involved with running an organization鈥檚 computers, making sure the related networks, systems, and security are operational. Computer scientists, on the other hand, generally work on designing and building computers and their programs. While computer science knowledge isn鈥檛 vital for some IT careers, IT experience and education is important for anyone hoping to pursue a computer science career.
Computer Information Technology Skills
As the demand for technology grows, so does the need for skilled IT professionals. If you鈥檙e curious about what it takes to work in this growing career field, here are some of the fundamental hard and soft skills you'll need:
- Tech savvy. Although specific technical skills differ by position, every IT job requires some degree of technical proficiency, including a foundational understanding of computers, software, and networks.
- Problem-solving and troubleshooting. IT professionals use these skills when determining why a line of code isn't working as it should or why a network connection has failed. Identifying the source of a problem is critical, as is your ability to assess situations, spot errors, and develop solutions.
- Communication. You鈥檒l need to be able to communicate effectively about IT systems鈥攂oth verbally and in writing鈥攖o audiences with varying technical backgrounds. This skill is especially useful if you鈥檙e in a role that supports professionals such as marketers, retailers, and lawyers.
- Information systems management. This skill helps IT experts collaborate with and assist other departments of an organization. It requires a basic understanding of how to manage a company鈥檚 network and allocate user permissions that connect employees with the resources they need.
