16 Computer Science And Technology Terms You Should Know

Many people want to be acquainted with tech and computer science at large. Still, not everyone wants to be a database administrator or a software engineer. The good news? Several other remarkable careers in the computer science and tech industry don’t require knowing how to code, including business development, recruiting, and marketing. Even if you’re not in a tech-savvy job, the vast amount of unfamiliar phrases utilized in the game might quickly make you feel lost. There are thousands of terms, abbreviations, and words that are associated with the field of Computer Science And Technology.

However, reading and processing every classification would take too much time. Not all will be related to your profession or what you are interested in learning. We’ve created a list of all the essential and commonly used terms related to tech and Computer Science And Technology science to make things easier on you. 

Bonus: These terms help you understand the general concepts of the two fields as well.

So here we go.

1. Cybersecurity

Cyber security refers to the process of safeguarding data against unauthorized users or hackers. It also forms a significant part of the tech and science industry as more and more businesses race to stay ahead of cybercriminals and security concerns. Furthermore, suppose you are keen on learning the dynamics of social science and determining the relationship between human behavior and technologies. In that case, a Master’s degree in cyberpsychology will help you accelerate. Also, before you enroll in this program, ensure that you have a tech-related undergraduate degree. 

2. A/B testing

This practice involves distributing two versions of online content, such as email marketing, to separate test groups to track each group’s participation. This type of testing is used to determine the best timing, method, or avenue of content for specific audiences. 

3. Big data 

Big data is a colloquial term for the massive amounts of data collected by organizations daily. This type of data can be used for several purposes, including trend analysis, automation, forecasting, and more.

4. Code 

Code is the string of directions or commands used by various programming languages to manage, edit, or create computer applications or programs. Computers use code to determine which course of action, define parameters, and do other things. 

5. Algorithm 

Algorithms are simply different methods used to solve computational problems at their most basic. As computing power and data abilities have improved, so have algorithms and the issues they seek to solve. A shipping company, for example, may use an algorithm to help determine the best path for delivery drivers.

6. Cookie

A small text file was sent to your computer by visiting a website. These can be very useful because these files allow the website to recognize your identity when you return. Cookies cannot store malware or other threats. Still, they can be used to track your activity across multiple websites to provide “targeted” ads. 

7. Firewall 

A firewall is a piece of computer software or hardware that limits the amount of data passing through it. Firewalls filter out unacceptable traffic in some way to prevent malware infection and other malicious activity while not interfering with legit user activity. 

8. Spam 

Suspicious email messages are generally commercial and are sent in bulk. The term is now more widely used to refer to such statements in various contexts.

9. Virtualization 

Virtualization refers to creating a virtual version of an IT resource, such as a device, server, storage, or operating system. It simulates the software and hardware required for a program to run. Virtualization creates virtual machines where programs can be run like a physical machine. 

10. User Experience (UX) 

It refers to designing technology to provide users with an accessible and responsive experience. While they are distinct terms, customer experience (CX), user interface (UI), and customer interface (CI) are frequently used interchangeably with UX.

11. API

An application programming interface (API) is a collection of functions that allows applications to access software features and collaborate to operate as needed. 

12. Syntax

Syntax provides a set of rules that govern a language’s structure. Programming languages, like all languages, require structure for the reader—whether a computer or a human—to understand the information. While some syntax components may be carried over from language to language, most programming languages have their own set of syntax rules that must be followed.

13. Machine learning

A fraction of artificial intelligence, machine learning makes inferences using patterns, statistical models, and algorithms to allow the machine to perform operations without being explicitly instructed by a user.

14. VPN

A virtual private network connects to a private network via a public network, allowing users to send and receive data from anywhere in the world safely.

15. Agile development

Agile development is a set of software development processes that include flexibility and creativity in software development. It means that the code is kept to a minimum and is tested frequently. Rather than waiting for everything to be completed, incremental but functional components of the software are released as they are ready. These components are operational and will assist users with their tasks. 

16. Business intelligence

One of the essential tech and science terms, business intelligence, refers to a collection of tools and software that businesses can use to analyze raw data. Data mining, reporting, and analysis are all part of it.


The world of science and technology is fascinating, with tons of information to learn. Though these terms only scratch the surface, they are enough to help you surf through your education and be your guide to learning lots of other terminologies. Remember that technical terms are crucial for all scientific and technical operations. So learn as much as you can and manipulate tricky concepts in your way.
