Explaining 10 Popular Tech Terms You Need to Know

Unlock the mystery of tech-speak with this guide to the top 10 must-know terms.

Technology has transformed our lives in countless ways, from the way we work and communicate to the way we shop and entertain ourselves. But with all the incredible innovations and advancements come a whole host of confusing tech terms that can leave even the savviest of users scratching their heads. Fear not, as we have compiled a list of ten popular tech terms and simplified them into easy-to-understand explanations. 

Whether you’re looking to improve your business’s cybersecurity or trying to navigate the latest advancements in virtual reality (VR) and augmented reality (AR), our breakdown of these essential tech terms will help you stay ahead of the curve. So, let’s get started on decoding the jargon and unlocking the secrets of the tech world!


API stands for Application Programming Interface. It is a set of protocols, routines and tools used for building software applications, allowing for easy communication between software components. They streamline the process of integrating software with other systems, saving developers time and effort.

For example, when you use a mobile app to book a flight ticket, the app uses an API to connect with the airline’s system and retrieve flight information, such as ticket prices and departure/arrival times. APIs are used in different fields, including web development, cloud computing and mobile app development, among others.


What You See Is What You Get”—WYSIWYG—is an innovative user interface that has made creating professional content accessible to even the most technologically challenged individuals. TinyMCE, Quill, Froala Editor and Simditor are some examples of WYSIWYG editors that allow users to edit content in a visual format that closely resembles the final output. 

WYSIWYG editors are commonly used in content management systems, website builders and email marketing platforms, empowering non-technical users to create and format text, add images and videos and customize layouts without needing to know HTML or other coding languages. With a real-time content display, users can see exactly how the content will look when published or sent. 

For example, if you use a WYSIWYG editor like Mailchimp to create an email campaign, you can choose from a variety of pre-designed templates or create your own custom email design using the drag-and-drop editor. This makes it easier for non-technical users to create professional-looking content without needing coding skills.


Extended reality (XR) is an umbrella term that encompasses virtual reality (VR), augmented reality (AR) and mixed reality (MR) (a combination of VR and AR). These technologies are designed to create immersive and interactive experiences that blur the line between the physical and digital worlds. 

From VR headsets that transport users to a fully simulated digital environment to AR applications that overlay digital information onto the real world, XR technologies have a wide range of applications in entertainment, education, training, etc. They are also increasingly being adopted by businesses for purposes such as product design, prototyping and remote collaboration.

Cloud computing

Cloud computing has revolutionized the way we access and utilize computing services. With the ability to access servers, databases and software over the internet, businesses and individuals can easily scale their usage up or down as needed instead of owning and managing physical servers and data centers. 

Cloud storage services like Dropbox, Google Drive or OneDrive have become commonplace, and cloud-based software such as Microsoft Office 365 or Google Workspace offers unparalleled convenience and flexibility. 


Artificial intelligence (AI) is at the forefront of modern technology, designed to help computers perform tasks with human intelligence, such as perception, learning, reasoning and decision-making. With machine learning, natural language processing, computer vision and robotics, AI is being used in a wide range of applications, from self-driving cars to voice assistants like Siri and Alexa. 

For example, in the healthcare industry, AI is being used to analyze medical images and assist with diagnoses, while in finance, it is being used to detect fraud and make trading decisions. 


Blockchain is a decentralized, digital ledger that records transactions securely and transparently. It consists of a network of computers that verify and approve transactions, making it highly resistant to fraud and tampering. Each block in the blockchain contains a unique digital signature, timestamp and a reference to the previous block, creating a chain of blocks that cannot be altered once recorded. 

The most notable application of blockchain technology is  Bitcoin, a decentralized digital currency that uses blockchain technology to record and verify transactions. Bitcoin transactions are processed by miners, who use powerful computers to validate and add new blocks to the blockchain, earning Bitcoin as a reward. Blockchain technology has applications beyond cryptocurrencies, such as supply chain management, digital identity verification and voting systems, among others.


5G is the fifth generation of mobile networks, offering faster speeds, lower latency and higher capacity than its predecessors. With advanced technologies such as beamforming, small cells and massive “multiple-input, multiple-output” (MIMO), 5G promises to deliver higher data transfer rates and more efficient use of spectrum. Its impact is already felt across industries, from autonomous vehicles to VR and AR.

For example, with 5G, you can download a full-length movie in seconds, stream high-quality video with no buffering and play online games with low latency. 5G is expected to have a significant impact on industries such as healthcare, transportation and manufacturing, enabling new use cases and business models.


As businesses increasingly rely on digital systems and data, cybersecurity is more important than ever before. The rise in remote work has created new challenges and vulnerabilities, making it essential for organizations to implement robust cybersecurity measures to protect against potential threats. In essence, cybersecurity is the practice of protecting computer systems, networks and digital assets from unauthorized access, theft, damage or disruption. It involves a range of measures and technologies designed to ensure the confidentiality, integrity and availability of information and data. 

Examples of cybersecurity threats include malware, phishing, ransomware and cyberattacks. Effective cybersecurity measures include a combination of software and hardware solutions, such as implementing firewalls, antivirus software and encryption, as well as employee training and awareness programs. 

Dark web

The dark web is a hidden realm of the internet that is not indexed by search engines and requires special software to access. It is often associated with illegal activities, such as drug dealing, weapons trading and human trafficking. However, the dark web also serves as a haven for whistleblowers and anonymous communication. 

For example, former intelligence contractor Edward Snowden used the dark web to leak classified information about the US. government’s surveillance programs. While the dark web can be a valuable tool for privacy and free speech, the dark web poses risks to users who must take precautionary measures to safeguard against malicious activities that can be difficult to trace.


Avatars are digital representations of users in a virtual world, game or online platform. Users can customize their online avatars by choosing their appearance, clothing accessories, etc. With avatars, users can engage with others in virtual spaces in ways that feel more personal and expressive than traditional text-based communication. For example, avatars can be used in virtual dating, where users can meet people and go on a virtual date with them with digital versions of themselves. 

In today’s fast-paced digital landscape, keeping up with the latest tech trends and terminologies is essential for anyone looking to stay competitive. These ten popular tech terms are just the beginning of a vast and complex world of technology, and staying informed is key to success. So don’t be intimidated by the new jargon but embrace it as a challenge to keep learning and growing in this exciting and ever-evolving world. Who knows, maybe you’ll even impress your tech-savvy friends with your newfound knowledge!
