Right Answer:
Ab Initio handles parallelism through two main types:

1. **Data Parallelism**: This involves splitting data into smaller chunks that can be processed simultaneously across multiple nodes or processes. Each node works on a different subset of the data.

2. **Component Parallelism**: This allows multiple instances of a component to run in parallel, enabling different operations or transformations to occur at the same time within the same graph.

Both types enhance performance and efficiency in data processing.

Right Answer:
Webhooks are user-defined HTTP callbacks that are triggered by specific events in a web application, allowing real-time data transfer. They differ from APIs in that APIs require a request to be made to receive data, while webhooks automatically send data when an event occurs without needing a request.

API

Ques:- What is rate limiting in APIs and how is it implemented

Asked In :- Vinove Software & Services Pvt Ltd, Object Frontier Software, Hidden Brains InfoTech, Netaxis IT Solutions (p), Rock Solid Solutions, Shipco IT, Walkover Web Solutions, Solace Infotech, Infinity Labs LLP, TNQ Technologies,

Right Answer:
Rate limiting in APIs is a technique used to control the number of requests a user can make to an API within a specific time period. It is implemented by setting thresholds (e.g., requests per minute) and using mechanisms like tokens, counters, or IP address tracking to monitor and restrict access when the limit is exceeded.

API

Ques:- What is the difference between REST and SOAP APIs

Asked In :- Winsoft Technologies India Pvt. Ltd, Xoriant Solutions Pvt Ltd, DREAMORBIT SOFTECH PVT, AnAr Solutions, Trigent Software, iROID Technologies, Dhruvsoft Services, TNQ Technologies, Define Labs, Sun Technology Integrators,

Right Answer:
REST (Representational State Transfer) is an architectural style that uses standard HTTP methods and is typically more lightweight and easier to use, while SOAP (Simple Object Access Protocol) is a protocol that relies on XML for message format and has strict standards for security and transactions. REST is generally more flexible and faster, while SOAP is more suited for enterprise-level services requiring high security and reliability.

API

Ques:- What is JSON and how is it used in APIs

Asked In :- Addweb solutions, Startup - Navya Network, Webvillee Technology, Cyber Group India, SENSEI Technologies, Fission Infotech, Principal Global Services, Noesys Consulting, Digital Nirvana Information Systems (I), Manipal Technologies,

Right Answer:
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. In APIs, JSON is commonly used to format data exchanged between a client and a server, allowing for structured data representation in requests and responses.

API

Ques:- What are RESTful principles and how do they apply to API design

Asked In :- STIC SOFT E-SOLUTIONS, Addweb solutions, Dhruvsoft Services, Elite Software Solutions, QUALYS SECURITY TECHSERVICES, Tredence Analytics Solutions, Spark Infosys, Noesys Consulting, Deligence Technologies, Technostacks Infotech,

Right Answer:
RESTful principles include:

1. **Statelessness**: Each API call must contain all the information needed to understand and process the request, with no stored context on the server.
2. **Client-Server Architecture**: The client and server are separate, allowing for independent development and scalability.
3. **Uniform Interface**: A consistent way to interact with resources, typically using standard HTTP methods (GET, POST, PUT, DELETE).
4. **Resource-Based**: APIs should expose resources (data entities) through URIs, and clients interact with these resources.
5. **Representation**: Resources can be represented in various formats (like JSON or XML), and clients can request the format they prefer.
6. **Cacheability**: Responses should indicate whether they can be cached to improve performance and reduce server load.

These principles guide the design of APIs to be scalable, efficient, and easy to use.

Right Answer:
Kanban focuses on visualizing workflow, limiting work in progress (WIP), and continuous flow. Scrum uses time-boxed iterations (sprints) with specific roles (Scrum Master, Product Owner, Development Team) and events (sprint planning, daily scrum, sprint review, sprint retrospective).

Use Kanban when you need continuous delivery, have evolving priorities, and want to improve workflow incrementally. Use Scrum when you need structured development with fixed-length iterations, have clear goals for each iteration, and benefit from team collaboration with defined roles.

3. **Generate Insights:** Facilitate a discussion to identify root causes and patterns.
4. **Decide on Actions:** Collaborate to define specific, actionable, measurable, achievable, relevant, and time-bound (SMART) improvements.
5. **Close the Retrospective:** Summarize action items and assign owners.
6. **Follow Up:** Track progress on action items in subsequent sprints to ensure continuous improvement.
