The fundamental building block of an operating system, the kernel controls actions involving the CPU, memory, and input/output devices. These resources are distributed to various tasks or processes according to the kernel's scheduling mechanism. The kernel is the most crucial element of an operating system and is in charge of managing system resources and offering services to user programs. The use of a preemptive or non-preemptive kernel is one of the important choices an operating system designer must make. A preemptive kernel is one that can switch to another process in the middle of a running one without the running ... Read More
Correlation is a statistical approach for determining the degree to which two variables are related. The Spearman's rank correlation coefficient, usually known as Spearman's rho, is a non-parametric correlation measure that assesses the monotony of two variables. It was named for its inventor, Charles Spearman, who created it in 1904. Assume we need to determine the age difference between two people. Spearman's rank coefficient can be used. There are two kinds of correlation: Parametric Correlation: It is known as a parametric correlation test because it assesses the linear dependency between two variables (x and y) ... Read More
Operating systems utilize a data structure called a precedence graph to show the interdependencies between various tasks or processes. Another name for it is a Task Dependency Graph. Several processes may be running at once in a multi-tasking operating system, and some of these processes may wait for others to finish before they can start executing. These dependencies are represented by a Precedence graph, which is a directed graph with each node being a process or task and edges denoting dependencies between tasks. In the precedence graph, each node's label indicates which process or task it corresponds to, and each ... Read More
The POSIX thread standard is followed by POSIX threads, sometimes referred to as pthreads. A program may be made parallel by using threads, which divide a single job into a number of separate ones that can run simultaneously. Threads in operating systems can either be user-level or kernel-level and are handled by the kernel. While the operating system manages kernel-level threads, user-level threads are totally controlled by the application. Kernel-level threads include POSIX threads. A thread creation and manipulation API is defined by the POSIX thread standard. The methods in this API allow you to start new threads, modify ... Read More
