What is Information Technology (IT)?

Computers power everything from calculators, to medical equipment, to complex satellite systems and the trading desk of Wall Street. They are powerful and invaluable tools to help people get their work done and enable us to connect with one another. 

So what exactly is information technology? IT is essentially the use of digital technology,  like computers and the internet, to store and process data into useful information.

The IT industry refers to the entire scope of all the jobs and resources that are related to computing technologies within society.

There are a lot of different types of jobs in this field, from network engineers who ensure computers can communicate with each other,  to hardware technicians who replace and repair components, to desktop support personnel who make sure that end users can use their software properly. 

But IT isn’t just about building computers and using the Internet, it’s really about the people. That’s the heart and soul of IT support work. What good is technology or information if people can’t use technology or make sense of the information? 

IT helps people solve meaningful problems by using technology, which is why you’ll see its influences in education, medicine, journalism, construction, transportation, entertainment,  or really any industry on the planet. 

IT is about changing the world through the ways we collaborate, share, and create together. 

IT has become such a vital tool in modern society that people and organizations who don’t have access to IT are at a disadvantage. IT skills are becoming necessary for day-to-day living, like finding a job, getting an education, and looking up your health information. 

Maybe you’re from a community where there wasn’t any internet, or you couldn’t afford a superfast computer and had to use one at your school or library instead.

There are many social and economic reasons why some people have digital literacy skills and other people do not. There’s a growing skills gap is known as the digital divide.  People without digital literacy skills are falling behind. But people like you are the real solution to bridging that digital divide. 

Overcoming the digital divide, not only involves confronting and understanding the combination of socio-economic factors that shape our experience, but also helping others confront and understand those experiences.

By getting into IT, you’ll help serve those in your communities or organizations and maybe even inspire a new generation of IT pioneers. 

When I think about solving the digital divide,  I can’t help but think of all the opportunities and breakthroughs that folks from diverse backgrounds and perspectives in the industry can bring.

By bringing more people of color, more women, more ethnically diverse people into the IT fields, we’re bound to see unique new ideas and products that we haven’t even begun to imagine that benefits everybody.

Information Technology (IT) career opportunities

  • Computer support specialists work on the front lines troubleshooting any technical issues including software issues, computer crashes, and hardware trouble. These specialists can also assist senior-level IT members with larger-scale network issues.
  • Network systems administrators specialize in the large picture of the network system, network security, and performance.
  • Computer systems analysts work behind the scenes to marry IT with smart business solutions. they typically concentrate on a specific industry while working for a technology firm or work directly in an industry, like finance or government.
  • Information security analysts are liable for the safety of an organization’s computer networks, conducting tests and developing company-wide best security practices.

Keep in mind that a number of these roles will change counting on the dimensions and scope of the corporate.
In smaller companies, most of your daily work may revolve around relatively mundane things like troubleshooting printers, but on the opposite hand, you’ll be required to be more of a jack-of-all-trades with broader knowledge.


With large firms, IT employees have a more diverse array of potential focus areas—some may go upward into management and strategic planning roles, while others may pursue specialized areas like cybersecurity.

Why Study Information Technology (IT)

Why study information technology (IT)? we are part of the most connected Society of all time the amount of interaction we have with computer systems in our daily lives has Drone grown dramatically.

Over the last few years particularly with younger generations computers are used by most people throughout their daily routine in fact information technology touches almost every aspect of our lives.

Most workers today interact with computers as part of their jobs even personnel that don’t work in an IT position generally depend on information systems to perform their job functions.

In some way even if you’re not intending to become part of the IT industry having a basic knowledge of information systems and information technology will help you become an informed user.

Inform your users to make better choices and become more valuable to the company if you’re intending to become part of the IT industry.

There are currently many career opportunities for a wide variety of jobs, in fact, in many areas of the world, there is a shortage of qualified personnel to fill available IT jobs.

Having a basic understanding of information technology is a critical first step in becoming a skilled IT worker even if you don’t work in an IT company or an organization.

You’ll have projects and operations and at some point, it’s likely you’ll become involved with those projects again.

Having a basic understanding of information systems will help you become a more effective team member in these projects.

Computing has changed dramatically over the last few years and devices that were only science fiction 10 or 20 years ago are now commonplace one term that defines modern computing.

The world is ubiquitous computing that is made to appear anywhere at any time most people in developed countries in the world now have multiple computing devices such as cell phones tablets wearable devices desktop computers and other types of systems.

In addition to this, there are many smart devices on the market as well on the list of these is growing every day many computer systems now work 24 hours a day seven days a week 365 days a year.

This has created a large demand for data center personnel to maintain these types of systems as the number of devices that are also coming online through a new technology called the Internet of Things.

This allows computer systems to control a large variety of devices from things such as kitchen appliances lights manufacturing equipment and all sorts of other types of devices.

This is also causing a large demand for software and commercial control systems to run these devices younger generations have grown up with this technology and have developed a lifestyle around mobile devices.

Internet is causing a large demand for information technology developers programmers and services the market for information technology systems is enormous.

As of 2016, there are over 2billion smartphones in use worldwide in addition as of 2008 in 2013 80% of US households had a personal computer.

Importance of Information Technology (IT)

With all of this growth and demand, there’s a great opportunity for information technology workers and many areas of the world.

There’s a shortage of personnel and filling jobs is difficult to fill shortages there’s been a rise in private training programs such as IT Bootcamp, in addition, to pay for computer programmers.

In Fermin information technology workers remains relatively high in fact computer programmers make an average salary of eighty-four thousand three hundred and sixty dollars in 2015.

I should note that this is from an article I found on US news and it’s based on US workers only salaries are highly dependent on the part of the world you’re living in as well as the part of the country you live in as well.

So even if salaries are lower in other parts of the world the demand for computer programmers and information technology workers remains strong.
