12 Best Free Online Information Technology Courses

What comes to our mind when we hear the term “information technology”?

For many of us who have no background in computers and the likes, we usually coin information technology with the people we call every time we encounter different issues with our computers at home. Although this is not wrong, this understates the wide scope of this crucial field. 

So, what is information technology? The simplest definition is the application of technology in solving organizational or business problems on a broader scale. Regardless of the role, any member of an organization’s IT department can deal with technology problems—big or small. 

There are three major pillars of responsibilities that encompass the IT department. 

1. IT Operations. This includes network maintenance, tech support, device management, and security testing. IT operations is a universal category for the IT department’s daily task.

2. IT Governance. This is the combination of processes and policies that guarantee the smooth and effective functions of the IT System. The process has to align with the needs of the organization strictly.

3. Hardware and Infrastructure. This refers to the physical elements of an IT infrastructure and includes the setup and maintenance of IT equipment like phone systems, servers, routers, and other personal devices like laptops.

Frequently Asked Questions

Is Information Technology Important?

Organizations will not smoothly work without the right IT systems. Finding a business that does not incorporate computer systems into its operations is next to none in this day and age.

As far as connectivity is concerned, businesses heavily rely on technology. To keep up with the best level of service, coupled with the most reliable and secure connectivity, business owners need the help of IT specialists to help them with their network.

As time passes, the majority of today’s companies want to apply more sophisticated and intuitive solutions. Technology blogger and Chief Information Security Officer Edward Kiledjian said the right IT personnel in a company is one of the keys to outsmarting, out-delivering, and outpacing business competitors.

With that, let’s take a closer look at what current and future IT specialists are expected to work on.

Data Overload: Every business processes massive amounts of data. Thus, this will need sophisticated software, solid processing power, and the best human analytical skills. 

Cloud Services. When storing huge amounts of data, most companies today believe operating their servers is no longer feasible. Thus, third-hosting platforms (cloud services) are getting more popular. And to maintain these remote platforms, it needs a professional IT expert.

Mobile and Wireless Usage. Most employers today offer remote work options for their employees, which require tablets, smartphones, and laptops that are roaming and wireless capable. 

Bandwidth for Video Hosting. Because of the worldwide COVID-19 Pandemic, videoconferencing has become more in demand than ever. This equates to more demand in network bandwidth. Thus, companies need the right people to handle such demand efficiently. 

Looking at the present situation, it’s not a surprise to hear that the demand for IT careers is growing. The Bureau of Labor Statistics confirms this, projecting an industry growth of 13% between 2021 and 2031. This is faster than the usual average for most occupations. 

Hardware vs. Software: Which IT Department is Which?

Perhaps you have clearly understood that software and hardware are the two largest parts of an IT department’s jobs. But what counts as software? And what is hardware? Here’s a breakdown to clearly understand their distinction.

Hardware, the computer system’s physical component, consists of the central processing unit, the motherboard, and the hard drive. Hardware can also be those other physical parts that you can connect to the outside of your computer like your printer, mouse, or keyboard.

Simply put, hardware is any component, device, or part of a computer and its network that you can physically manipulate and touch. 

Software, meanwhile, is something that you can’t change physically. It includes all the programs, data, and applications stored in the computer electronically, like an audio editing app or an operating system. 

So how does this difference relate to a career in the IT department? Most IT jobs today require a combination of both software and hardware-based know-how.

Some IT professionals spend more time configuring hardware components, although these things are also administrated by software. Also, IT professionals are obliged to deploy and set up software apps for many users. 

What Career Opportunities Await an IT Professional?

After understanding the general obligations of an IT department, perhaps you’re wondering by now what specific individual roles await an IT professional. Below are some of the key positions you can find in an IT department:

Network Systems Administrators. These people focus on the bigger picture of a network system, performance, and security.

Computer Support Specialists. They are the frontrunners in the IT department. They are responsible for troubleshooting technology issues like computer crashes, software problems, and hardware trouble. These IT professionals may also work with senior-level IT specialists in a larger-scale network issue. 

Information Security Analysts. These professionals are the ones tasked to secure the computer network of an organization. They conduct tests and develop the best network security practices in a company.

Computer Systems Analysts. The people behind the scenes integrate the best IT principles with the best business solutions. Usually, they focus on a specific industry while working for an IT firm, although some directly work in an industry, like the government or finance. 

What Are The Important Skills for Information Technology?

Coding Skills

Writing code is one of the basic skill sets that an employer will look for in an IT professional. An employer seeks a candidate who can code in multiple languages if the job involves programming or software/web development, as many systems are built using various languages.

To see a software development project and manage things like QA, an IT professional should also understand the process of code writing (quality assurance).

• Application Development
• Architecture
• Artificial Intelligence
• Cloud Computing
• HTML
• C++
• C Language
• PHP
• UX Design
• Python
• JavaScript
• Java
• Ruby

Time and Project Management

Many field professionals will need to be self-directed and self-motivated, and being self-directed means managing projects effectively. Technology work frequently takes longer than expected, as evidenced by how often timelines and milestones change over a long project.

An IT professional should accurately estimate how long a project will take and then stick to those timelines. They should also be capable of assisting an entire team in managing their workload daily, weekly, monthly, and project-by-project basis.

• Scheduling
• Goal-Oriented
• Digital Communications
• Manage Remote Working Teams
• Continually Review Processes for Improvement 
• Multitasking
• Meeting Deadlines
• ICT (Information and Communications Technology

Communication Skills

Communication skills are essential for anyone working in IT because information technology professionals frequently work across multiple teams and groups. IT professionals are often called upon to provide technological solutions for people who are not as tech-savvy.

They must demonstrate leadership at all levels of projects and with a wide range of groups. They are frequently required to present ideas and reports to larger groups of people.

Building teams and fostering collaboration among peers will be a part of an IT professional’s job.

• Team Building
• Teamwork
• Leadership
• Collaboration
• Written Communication
• Oral Communication
• Active Listening
• Communicating Complex Information in Digestible Amounts

Knowledge and Computer Networks

Networking knowledge will be required of most IT professionals in both large and small businesses. Knowledge networking is part of good communication skills.

It necessitates gathering groups of people in a working environment to share what they know to build a knowledge system within an organization that is greater than the sum of its parts.

Some IT jobs on the other side of “networks” may include network architects, engineers, and systems administrators. Network administrators (or systems administrators) are in charge of a more extensive system’s day-to-day operations.

• SQL
• JavaScript
• Python
• Cloud Systems Administration
• C++
• Functionality
• Cyber Security
• IP Setup
• Wireless Modems/Routers
• Cloud Services
• PHP
• Information Management

Career Outlook for Information Technology Jobs

From 2022 to 2032, employment in information technology occupations is expected to grow 13 percent, faster than the average for all occupations. These occupations are expected to generate 667,600 new jobs.

The increased emphasis on cloud computing, extensive data collection and storage, and information security will increase demand for these workers.
