Case Studies

A WebSocket connection is persistent primarily because it is built on top of a TCP socket, which is inherently connection-oriented and maintains state in memory at both the client and server OS. This persistence begins with the TCP 3-way handshake and continues as long as the socket remains open and...

In relational databases like PostgreSQL, foreign key constraints are the traditional mechanism for enforcing relationships between tables, ensuring data integrity by validating references during inserts, updates, and deletions. However, while effective for small to medium-scale applications, foreign...

Apache Kafka, is tech-nervous system that routes, transmits and processes the infinite event-data (stream) almost instantly and always on listening , the event driven system with high-throughput, scalable, permanent-storage and high-availability.

This case study contains the insight of challenges while developing a model that perform good or bad according to the specific requirements. It includes all possible main problems needs to be fixed before we develop the machine learning model fit. Learning algorithm selection, data selection and pro...

This case study explores how various programming languages implement the `net` package for low-level networking and how these abstractions power protocols like HTTP, TCP/UDP, and WebSockets. The goal is to understand system-level socket programming and its critical role in building scalable servers,...
