What is kernel-level programming in an OS? Kernel-level programming involves writing software that interacts directly with the operating system's core functions (the kernel). This type of programming requires s
The traditional Linux kernel is a monolithic kernel, meaning it includes all the core functionalities, such as device drivers, file system management, and system calls, within a single large binary. This design can lead to high performance since all components run in the same address space, but...
Kubernetes is an open-source container in cloud computing platform that is a containerized application. Kubernetes allows developers to manage and deploy containerized applications at scale, provides features such as automatic scaling, load balancing, and self-healing. By containerizing Kubernetes, develo...
While they all have the Linux kernel in common, various Linux distributions build their own operating systems on top of the basic open-source foundation. Linux distributions, referred to as “distros,” boast a range of backgrounds and features. Ubuntu is the world’s most popular free OS and...
Add kernel and hardware rootkit protection. Kernel integrity checks can be implemented to foil a hacker's prediction of the location of kernel code; KASLR (Kernel Address Space Layout Randomization) is an example. Hardware tools such as the Trusted Platform Module (Intel) and Secure Processor (AM...
The Linux kernel communicates between the hardware and applications via "interrupts." When the hardware wants to interface with the application and broader system, an interrupt is issued across the processor and kernel to manage resources efficiently. The kernel, existing inside a hard OS shell, con...
What Is Cloud Computing? Cloud computing is a hosted service delivered over the internet that allows users to access files and programs anywhere, eliminating the need to always be near physical hardware. Cloud Computing Service Types Cloud computing services are broken down into three major categories...
Linux kernel benefits Today, Linux is one of the most widely used open-source operating systems in the world. This is largely due to the flexibility and effectiveness of the Linux kernel. It provides many of the management and control capabilities that make Linux OS such a powerful platform, ...
more computing processes moved to this servers-and-infrastructure part of the Internet, people began to talk about moving to "the cloud" as a shorthand way of expressing where the computing processes were taking place. Today, "the cloud" is a widely accepted term for this style of computing....
A virtual machine (VM) is a computing environment that functions as an isolated system with its own CPU, operating system (OS), memory, network interface, and storage, created from a pool of hardware resources. A VM can be defined by a single data file. As an isolated environment, it ca...
