In computer programming, system calls and library calls are essential mechanisms used to interact with the underlying operating system and perform various operations. While they both involve invoking functions or routines, there are distinct differences between system calls and library calls. Understanding these differences is crucial for developers to efficiently utilize these mechanisms in their applications. This article explores the dissimilarities between system calls and library calls, shedding light on their respective characteristics and functionalities. What is System Call? A system call is a mechanism provided by the operating system that allows user-level programs to request services from the operating ... Read More
Context switching is a fundamental operation performed by an operating system to manage multiple threads or processes in a multitasking environment. It involves saving the current execution context of a thread or process and restoring the execution context of another thread or process. This allows the operating system to quickly switch between different threads or processes, giving the illusion of concurrent execution. There are two types of context switches: "thread context switch" and "process context switch". Let's explore the differences between them. What is Thread Context Switch? A thread context switch refers to the process of saving the current ... Read More

In programming, system−level calls are used to interact with the operating system and perform various tasks. Two commonly used system−level calls are system() and execl(). While both these calls allow executing external programs, they differ in their functionality and usage. What is system() Call? The system() call is a higher−level function that allows the execution of shell commands or scripts. When system() is invoked with a command as its argument, it starts a new shell process, which then interprets and executes the specified command. The system() call provides a simple way to interact with the command line and execute external ... Read More
In data analysis and visualization, hierarchically-clustered heatmaps provide a powerful tool to reveal patterns and relationships within complex datasets. This article explores how to create a hierarchically-clustered heatmap using Seaborn Clustermap in Python. To assist you in comprehending the process, we will walk you through the procedure step-by-step utilizing code examples. We will instruct you on how to cluster and visualize the data, this will provide you with important information regarding the relationship between each variable. What is a Hierarchically-Clustered Heatmap in Python with Seaborn Clustermap? A hierarchically-clustered heatmap is a visualization technique used to display a matrix of ... Read More
In software development, stubs and drivers are commonly used techniques to facilitate testing and the development process. They serve different purposes and play distinct roles in software testing and integration. Let's explore the difference between stubs and drivers. What are Stubs? Stubs are dummy implementations of modules or functions that are called by the component being tested. They simulate the behavior of the dependent modules that are not yet developed or available for testing. Stubs are typically used when testing higher−level components that depend on lower−level components. The main purpose of stubs is to provide a simplified or mock version ... Read More
An operating system (OS) is a group of programs that controls computer hardware resources and offers standard services to software applications. It serves as a conduit between the user and the hardware. It is accountable for carrying out all procedures. There are many operating systems available for mobiles, pc etc., AIX and Chrome OS are such operating systems. The following are the differences between them. What is AIX OS? Advanced Interactive executive is commonly referred to as AIX. IBM created the AIX operating system in 1986. The organization originally created this operating system for RT PC RISC workstations, but ... Read More
In UNIX−based operating systems, such as Linux, there are two types of CPU time that are commonly measured: user CPU time and system CPU time. These metrics provide insights into how the CPU resources are being utilized by different components of a system or process. Understanding the difference between user CPU time and system CPU time is essential for performance analysis and troubleshooting. What is User−CPU−Time in UNIX? User CPU time represents the amount of CPU time spent executing in user mode, which is the mode where application code runs. It includes the time spent executing the user's program ... Read More
