For Professional Technical Writers — Part 1

Technical writing

Essential Terminologies You Need To Know. These are some common interview topics for technical writing.

Understanding key technical terminology is essential for technical writers to broaden their knowledge and navigate technical discussions and interviews more easily. Knowing these terms allows writers to communicate effectively with subject matter experts, understand product functionality in depth, and create clear, accurate documentation.

Mastering core terminology is also crucial in technical writing interviews and assessments, where candidates are often evaluated on their familiarity with industry language and concepts.

This guide is a starting point, covering 30 foundational terms every technical writer should know to stay relevant and enhance their credibility in technical environments.

And this is just the beginning — stay tuned for more terminology guides! Your suggestions are always welcome; feel free to share topics you’d like me to explore next as I build this resource for writers passionate about excelling in tech.

30 fundamental terminologies for technical writers

1. API (Application Programming Interface)
   APIs are sets of rules allowing different software applications to communicate. They enable developers to interact with an app’s features or data without knowing the underlying code. For technical writers, documenting APIs means explaining functions, inputs, and outputs.
2. SDK (Software Development Kit)
   SDKs are toolkits that provide developers with resources to build applications. They usually include APIs, libraries, and documentation. Understanding SDKs helps technical writers guide developers in integrating and utilizing these resources effectively.
3. UI/UX (User Interface/User Experience)
   UI refers to the design elements users interact with, while UX covers the overall experience, accessibility, and satisfaction. Writers document both UI and UX to help users navigate software efficiently.
4. Version Control
   Version control systems like Git help track code changes over time, allowing multiple developers to work on a project simultaneously. For writers, version control is essential for managing documentation changes and ensuring alignment with software updates.
5. Agile/Scrum
   Agile is a project management approach emphasizing iterative development. Scrum, a popular Agile framework, organizes work into sprints and includes defined roles and workflows. Technical writers in Agile teams create documentation incrementally, aligned with development progress.
6. Codebase
   A codebase is the complete collection of an application’s source code. Access to the codebase helps writers understand the software’s structure and logic, aiding more accurate documentation.
7. IDE (Integrated Development Environment)
   An IDE is a software suite providing coding, debugging, and testing tools. Familiarity with IDEs helps technical writers document development workflows and assist users with setup processes.
8. Framework
   Frameworks provide pre-built structures for application development. Examples include Angular, React, and Django. Writers can explain how developers can use frameworks to structure their work and leverage built-in tools.
9. Parallelism
   Parallelism refers to executing multiple tasks simultaneously, and it is commonly used in high-performance applications. To enhance software efficiency, writers documenting parallel processing should clarify which tasks run concurrently.
10. Installation
    Installation involves setting up software, including checking prerequisites and following specific steps. Clear installation instructions are crucial for a positive user experience and successful software setup.
11. Deployment
    Deployment is the process of making an application or update available to users. Writers document deployment steps and provide rollback instructions, ensuring smooth software delivery.
12. Source of Truth
    A source of truth is the authoritative source for a particular dataset or information within an organization. Writers use it to ensure documentation accuracy and to reference reliable, centralized information.
13. Build/Compile
    Building or compiling refers to transforming source code into executable files. Documenting the build process helps developers or system administrators understand how to generate software that runs on target platforms.
14. Database
    A database stores and organizes data, and there are types like SQL (relational) and NoSQL (non-relational). Writers often document database structures, queries, and access methods to guide users in storing or retrieving information.
15. Cloud Computing
    Cloud computing delivers computing resources over the internet. Providers such as AWS, Google Cloud, and Azure offer scalable infrastructure, enabling writers to document the setup and maintenance of cloud-based applications.
16. Middleware
    Middleware connects different applications or systems, allowing data exchange and communication. Writers document middleware functions, integration points, and troubleshooting to support smooth system interactions.
17. Latency and Bandwidth
    Latency is the delay before data transfer, while bandwidth is the maximum transfer rate. Writers covering networked applications often discuss the requirements for optimal performance, particularly with respect to latency and bandwidth.
18. CI/CD (Continuous Integration/Continuous Deployment)
    CI/CD automates code integration and deployment, streamlining releases. Writers document CI/CD workflows to help developers understand the automated pipeline’s build, testing, and deployment steps.
19. Containerization
    Containerization packages an application and its dependencies into a container, allowing it to run consistently across environments. Docker is a popular tool. Writers document containerization steps for reproducible, portable applications.
20. Encryption
    Encryption encodes data to prevent unauthorized access using protocols like SSL, TLS, and HTTPS. Writers document encryption standards to explain how software secures user data.
21. Microservices
    Microservices architecture builds applications as a collection of loosely coupled services, each handling specific functions. Writers document microservice interactions and individual services’ tasks for a modular understanding.
22. REST and SOAP
    REST (Representational State Transfer) and SOAP (Simple Object Access Protocol) are web service protocols. REST is simpler, while SOAP is more secure and structured. Writers document API protocols, helping developers select the best integration method.
23. Workflow
    A workflow is a series of tasks that achieve a particular outcome. Documenting workflows helps users follow processes for setting up software or managing configurations.
24. JSON and XML
    JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are data interchange formats used in APIs. JSON is lightweight and common, while XML is more flexible and structured. Writers document both data transfer formats for guidance.
25. Scripting Languages
    Scripting languages, such as Python and JavaScript, are used to automate tasks. Writers may document scripts and their functions, providing users with customization and automation options.
26. SSL/TLS (Secure Sockets Layer/Transport Layer Security)
    SSL and TLS are encryption protocols used to secure data in transit over the internet. Writers document these protocols to explain how software ensures secure communication and data protection.
27. Load Balancer
    A load balancer distributes network or application traffic across multiple servers to ensure reliability and scalability. Writers document load balancers to help users understand how traffic is managed for optimized performance.
28. Cache
    A cache is a temporary data storage area that speeds up data retrieval. Caches improve application speed and performance, and writers document cache mechanisms to explain how users can benefit from faster data access.
29. Data Migration
    Data migration involves moving data from one system or format to another, often during system upgrades or cloud adoption. Writers document migration steps, helping users navigate the process while maintaining data integrity.
30. Debugging
    Debugging is the process of identifying and fixing errors in software. Writers documenting debugging procedures help users troubleshoot and resolve issues, often using tools like logs and error messages.

Technical Writing is Vast

These terminologies are foundational for any technical writer aiming to create accurate and user-friendly documentation. Mastering these terms will give you a head start, whether preparing for interviews, striving to improve your daily interactions, or building a strong technical knowledge base.
