Swap memory, also known as swap space, is a feature in computer systems that acts as an extension of physical RAM (Random Access Memory). It comes into play when RAM becomes full and the system needs additional space to store and manage running processes. Here’s a breakdown of how swap memory works: RAM Priority: Physical
Demystify GVK in Kubernetes and unlock the power of the Kubernetes API. Learn how GVK helps manage resources, ensures version control, and fosters extensibility.
In software development, two crucial concepts govern how components interact and ensure compatibility: API (Application Programming Interface) and ABI (Application Binary Interface). Although these terms are used interchangeably but they serve distinct purposes and operate at different levels of abstraction. Let’s explore each concept to understand their significance and differences. API: Bridging Software Components An
Inter-Process Communication (IPC) allows processes with separate contexts to communicate. Common IPC methods include pipes, FIFOs, and message queues. However, what if processes are on different hosts? Sockets provide data exchange between applications on the same or different hosts connected via a network. In a client-server scenario, applications use sockets to communicate. Here’s how it
