Information Technology plays a major role in our day-to-day life with or without the knowledge of us. People who pursue their degree in IT, IT-related background and the ones working in IT may know these terms familiarly. This blog is for the ones who are thinking to have a career in Information technology or if you’ve just joined the industry. Here are the most common IT terms you ought to know. Let’s gather some knowledge about unique words/term, their definition and explanation.

1. Amazon Web Services (AWS)

AWS is a cloud computing platform. It offers a wide range of services including computational power, database storage, and content delivery and is constantly adding more. It is an on-demand service that offers a pay-as-you-go pricing system. It is by far the dominant cloud computing platform in the field. 

2. Artificial Intelligence (AI)

AI is also known sometimes as machine intelligence, artificial intelligence is intelligence that is demonstrated in a machine. The goal is to create machines or programs that can work, react, and respond like a human. This can include speech recognition, learning, planning, and problem-solving.

3. Big Data

Big data describes the phenomenal growth, use, and accessibility of information. This comes from a lot of sources such as social media updates, search data, multimedia content, and even climate information, among others. As such, it could be structured or unstructured. Big data could also mean the rise of new tools to analyze all the data available to you.

4. Blockchain

Blockchain is a ledger system that uses an open, distributed record to keep track of transactions – transactions could mean cryptocurrencies, medical information, voting or home records, and more.

5. Business Intelligence (BI) 

BI refers to an array of software and tools that businesses can use to analyze raw data. It includes data mining, analysis, and reporting

6. Cloud Computing

Cloud computing is an umbrella term that includes products, services, and platforms that allow businesses and other users to access computing resources that are delivered to them over the Internet or other networks.

7. Crowdsourcing

Crowdsourcing means the outsourcing of your tasks to, well, a crowd of people. That is, you will have a loosely defined group, which will do the work for you. Crowdsourcing takes away the task that you have to do in-house or by using an employee and letting a bigger group of people do it. In IT, crowdsourcing usually involves the general public.

8. Customer Relationship Management (CRM)

CRM refers to a set of processes, tools, technologies, and software that help businesses manage their relationships with their customers. For instance, a customer relationship management software would be able to give businesses enough details about their customers from the level of communication that has been done by each customer and when. This allows businesses to personalize and customize their contacts with the customer to gain more sales.

 9. Data

Data is distinct pieces of information, usually formatted in a special way. All software is divided into two general categories: data and programs. Programs are collections of instructions for manipulating data. Data can exist in a variety of forms – as numbers or text on pieces of paper, as bits and bytes stored in electronic memory, or as facts stored in a person’s mind. Since the mid-1900s, people have used the word data to mean computer information that is transmitted or stored. Strictly speaking, data is the plural of datum, a single piece of information. In practice, however, people use data as both the singular and plural form of the word, and as a mass noun (like “sand”).

10. Domain Name Service (DNS)

The DNS is the phonebook of the Internet. Humans access information online through domain names, like or Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources. Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as (in IPv4), or more complex newer alphanumeric IP addresses such as 2400:cb00:2048:1::c629:d7a2 (in IPv6).

11. Information Technology Infrastructure Library (ITIL)

ITIL is a framework designed to standardize the selection, planning, delivery and maintenance of IT services within a business. The goal is to improve efficiency and achieve predictable service delivery. The ITIL framework enables IT administrators to be a business service partner, rather than just back-end support. ITIL guidelines and best practices align IT department actions and expenses to business needs and change them as the business grows or shifts direction.

12. Internet of Things (IoT)

IoT is the network of devices such as cars, speakers, and sensors that share information and connectivity. This network allows you to control the lights in your home using an app and can notify the grocery store when you’re running low on milk in the fridge, for example. Computers and phones—while used for connecting—are not typically called IoT devices because the term is usually reserved for devices that wouldn’t be expected to have an Internet connection and that can communicate without human interaction.

13. Machine Learning (ML)

ML is the ability of a program to develop and progress in a specific task without using explicit instructions, allowing the program to rely on patterns and inference instead. Machine learning allows for a machine or program to develop and create a solution on its own once limitations and standards are set, rather than simply the following programming.

14. Natural Language Processing (NLP)

NLP is when machine-learning algorithms are trained to comprehend large amounts of human language and respond to those commands. You might hear about this machine learning technique most when you are reading about voice assistant products that can respond to multiple spoken commands at once, like Amazon’s Echo. 

15. Virtual Private Network (VPN)

VPN allows users to make a secure connection that uses encryption to maintain their privacy. This is far safer than connecting to a public Wi-Fi network which is extremely vulnerable. If you use a VPN, your data is encrypted before it passes through the public Wi-Fi network, meaning that you can be sure your data is safe. It acts as a barrier between you and less secure networks.

16. Wearables

Wearables is an IT term that refers to wearable technology. This includes devices like smartwatches and fitness bands. These devices are usually paired with a smartphone or other device that has access to the internet, but some devices do not require a parent device to function.
