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 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

HTTP is an application layer protocol created to transport data between networked devices. In HTTP, a number of methods are accessible. These methods represent the CRUD (create, read, update, delete) operations, in that order. Some HTTP methods share a lot of the same traits. Therefore, before implementing these comparable HTTP methods in an HTTP system, we should thoroughly study them. For instance, there are similarities between the features of the PUT and PATCH methods that may cause confusion. Both are used to update a resource at a particular location. The following are some of the differences between them. What is ... Read More

Virtualization and hypervisor are closely related concepts in the field of computer science, specifically in the domain of system virtualization. While they are interconnected, they represent different aspects of the virtualization technology. What is Virtualization? Virtualization is a technique that allows the creation and operation of multiple virtual environments or virtual machines (VMs) on a single physical computer or server. It enables the sharing of hardware resources, such as processing power, memory, and storage, among multiple operating systems or applications. Each virtual machine functions as an independent and isolated entity, running its own operating system and applications. There are 4 ... Read More

Natural disasters can be some of the most terrifying and destructive events that can occur on our planet. Among these, earthquakes and volcanoes are two of the most common natural disasters. Although both are related to the Earth's crust and can have devastating consequences, they are distinct phenomena with their own characteristics and causes. In this essay, we will explore the differences between earthquakes and volcanoes. What are Volcanoes? A volcano is a vent or opening in the Earth's crust through which molten rock, ash, and gas can escape. Volcanoes are usually located at the boundaries of tectonic plates or ... Read More
