Primotly's IT Glossary: All the tech terms you should know

14/09/2022

The IT world consists of dozens of acronyms, specialized terms, and slang expressions used by developers and teams working on digital products. That's why we've prepared a comprehensive glossary that will make developers, team members, young IT job seekers, and, most of all, customers to better understand each other.

A/B testing

A research method that allows you to see what type of product or content will be best for the user. It involves comparing two versions of a website to select the version that better fulfills the assumed tasks. A/B testing checks which elements of the interface the user spends more time on or is more willing to use. Comparisons can be made between the currently functioning version of the site and alternative versions.

Accessibility

A field of knowledge concerning human-computer interaction dealing with the problems of creating websites and web services accessible to the widest possible audience, with particular emphasis on people at risk of digital exclusion (e.g., people with disabilities).

Agile

Agile is an iterative approach to software development that helps reduce the problems that occur and deliver the finished product faster. Self-managed Agile teams deliver work in stages. Requirements, plans, and deliverables are constantly evaluated, allowing faster response to changes that evolve during the process.

Algorithm

An algorithm is a "recipe" for performing some task. It is a sequence of steps that must be performed in the correct order to get the expected result. A defined algorithm can be written in various programming languages. Algorithms help organize the structure of a digital product and describe its functionalities.

Amazon Web Services

AWS is the most popular and developed cloud platform that provides computing power, storage, databases, artificial intelligence, blockchain, applications, and much more. It currently offers more than 160 services available over the Internet in a Pay-As-You-Go model.

Angular

Angular is a comprehensive framework developed by Google for designing and developing high-performance applications. It provides the developer with a set of ready-to-use tools and solutions that can be modified or supplemented with your code.

API (Application Programming Interface)

Application Programming Interfaces allow applications to connect and communicate with separate systems. API integration makes it possible to augment the functionality of digital products through data from external sources. With APIs, developers can build interactions between applications that users use daily.

Application

An application is a usable computer program that performs specific tasks. It can be any stand-alone program or an element of a software package that is not classified as system and utility software.

Backend

The backend is everything on the server that the user does not have direct access to. The backend is hidden behind the frontend (that is, what runs on the user side) and manages the entire system of a given application or website.

Back-end developer

The back-end developer specializes in creating the engine of the application or website and taking care of the database and server side.

A navigation technique used in user interfaces to increase their usability. Its purpose is to allow users to track their current location on a website or app.

Bug

An error in the software prevents it from working fully correctly. It can cause minor inconveniences or make it completely impossible to run the application (such a bug is called critical). A bug usually results from human error at one of the stages of software development (sometimes also at the design stage).

Building products

A partnership model where a complete team of relevant specialists designs and develops ready-to-use Internet platforms, applications, or custom software solutions that meet the client's needs.

Cache

The cache stores frequently used data. This makes access to them as fast as possible. Some files downloaded from the server are stored on the computer's disk. This reduces the amount of data to be downloaded, and the application or page loads faster.

Cloud computing

A modern IT technology for processing and storing data that is not stored on computer disks, but on servers outside the local network, on what is known as the cloud. The resources are delivered quickly (on demand) with minimal management effort and with minimal vendor involvement. The cloud is all the servers, software, fiber, etc. that can be accessed via the Internet.

CSS (Cascading Style Sheets)

CSS is used to format the layout of a webpage. It describes the layers of presentation, such as colours, layout, or fonts. CSS style sheets are nothing more than sets of guidelines that regulate the appearance of certain components.

CTA (Call to Action)

A call-to-action (usually in the form of a button), is intended to persuade the recipient to take a specific action. This can be an incentive to fill out a form, download an application, subscribe or click on a link. Using CTAs on pages helps optimize the conversion rate.

Database

A database is a collection of data stored according to certain rules. They are structured, which facilitates their processing. A database is usually controlled by a database management system (DBMS). The data, the DBMS, and the related applications together form a database system.
