Now we are ready to turn to memory allocation. One of the simplest methods for allocating memory is to divide memory into several fixed-sized partitions. Each partition may contain exactly one process. Thus, the degree of multiprogramming is bound by the number of partitions. In this multiple partition method, when…

A deadlock occurs when a process or thread enters a waiting state because a requested system resource is held by another waiting process, which in turn is waiting for another resource held by another waiting process. Deadlocks may also involve different resource types. For example, consider a system with one…

Process Synchronization is coordinating the execution of processes such that no two processes access the same shared data and resources. It is especially needed in a multi-process system when multiple processes are running together, and more than one processes try to gain access to the same shared resource or data…

Deadlock is one of the underlying topics in Operating Systems. Deadlock is nothing but when two or more processes are waiting on happening of some event to occur, which never happens then we say these processes are in deadlock. Deadlock can arise if these four conditions occur simultaneously Mutual Exclusion…

Covariance and PCC — Hola!! readers in this article we will look at the two most important and interesting concepts in statistics. They are Covariance and Pearson Correlation Coefficient. Okay without any further due let’s get started with Covariance as it is the base for Pearson Correlation Coefficient. Covariance Covariance is the measure of the…

#5 Wide-columnar by Google Cloud BigTable. — Databases are one of the key factors in the IT Industry. Many companies are working on developing different types of databases for different use cases. There are many job fields in databases. Databases are mainly used to store data. Developers select suitable databases according to their needs. So here in…

Quick and cool explanation — This article could be considered as an introduction for beginners or a quick refresher for experienced. What is Chebyshev’s Inequality? Chebyshev’s theorem is used to determine the proportion of events you would expect to find within a certain number of standard deviations from the mean. For normal distributions, about 68% of results will fall…

Follow these!!! — Data visualization is an essential step in the data science process. It’s the process where you represent your conclusions and report the results of your analysis in a graphical format that is easy to understand. Data visualization takes hard work, cleaning, analysis, and manipulating messy data into beautiful graphs…

Everything you need to know about K-means clustering — Data is essential for data science. With a lot of data being generated every second, it’s no surprise that most of this data is unlabeled. But this is okay because there are different techniques, to handle unlabeled datasets. Even there’s an entire domain of Machine Learning called “Unsupervised Learning” that…
