Overview Mutexes (mutual exclusion locks) are synchronization primitives provided by the Linux kernel to hendle concurrent accesss to shared resources. Unlike semaphores which allow multiple concurrent access, a mutex ensures that only one thread can hold the lock at any given time. This article demonstrates how to integrate mutex synchronizati ...

0. TCP/IP Network Model Layers The TCP/IP model consists of four layers: Application, Transport, Internet, and Network Access. 1. Linux Commands for Process Status, Memory Usage, and tar Extraction Process Status: Use ps command. For example, ps -aux | grep PID shows the status of a specific process. Memory Usage: Use free command. For example, ...

Threads represent the smallest unit of CPU scheduling, operating within a process that manages resource allocation. While a single thread executes instructions sequentially, multithreading enables concurrent or parallel execution flows to maximize multi-core processor utilization and increase application throughput. The fundamental challenges i ...

In concurrent programmnig, a shared counter must be thread-safe to prevent data races and inconsistencies when accessed by multiple threads simultaneously. Two primary approaches to achieve this are using atomic variables and explicit synchronization via locks. Using AtomicInteger AtomicInteger provides atomic operations without requiring expli ...
