Computing has been the most disruptive influence to impact the business world. Its continuing rapid evolution seems to ensure a future for IT certifications. Computers have been in use since 1821, following Charles Babbage’s visionary design of his Difference Engine No.1 with the ability to calculate polynomial functions and print the results in tabular form. His efforts were further improved by one Ada Lovelace, a daughter of the poet Lord Byron, accredited with writing the world’s first computer programme.

Despite the many advances in between, the dawn of what we now term “the digital age” occurred much more recently, with the birth of the PV followed by the World Wide Web and the internet browser. Gone were the days when computers were the size of a large room, to be replaced by compact units that could fit on a desktop, albeit somewhat oversized and limited compared to today’s laptops, slimline all-in-one machines, and tablets. Almost overnight, personal computers became a necessity in our homes and offices, creating a demand for people with certified IT skills.

Digital technology has continued to evolve and now impacts most of the world’s commerce and industry and its citizens’ daily lives. In short, there are few better ways to ensure a lucrative career than an IT qualification.

A Brief Review of Available IT Certifications

Estimates vary widely, with some suggesting that as many as 9,000 programming languages may have been developed since Ada Lovelace’s groundbreaking algorithm. Some were relatively exotic and intended only for a single niche application, and while there are many legacy systems still in use, only around 50 coding languages are employed regularly, and relatively few of these are constantly in high demand. Anyone seeking IT certifications would be well advised to set their sights on the following three:

  • Java: This is a winning choice for many reasons. It is an object-orientated language that is easy to learn because its syntax closely resembles written English. More significantly, cross-platform compatibility and the Java virtual machine allow users to write code once and run it anywhere without modification. It can be used to develop desktop, Android and webpage applications, online games, and the Internet of Things (IoT), to name only a few.
  • C# (Pronounced See Sharp): This derivative of C runs on Microsoft’s .NET framework, making it exceptionally scalable. It shares many of Java’s abilities and features an extensive library, providing high-level functionality that positions it as a significant challenge to Java’s 28-year domination. Nevertheless, the demand for programmers with IT certifications in either of these two languages is similar and growing.
  • Python: The main strength of this high-level language is its readability, making it a favourite both with veterans and newbies. Along with Javascript and Node.js, Python is one of the best choices for cloud computing, a trend that seems destined to expand as the volume of digitised data grows exponentially. AI and machine learning developers also favour Python.
