The document discusses different types of operating systems including desktop operating systems, server operating systems, and mobile operating systems. Desktop operating systems are recommended for personal use by different groups for reasons like ease of use, stability, and capabilities. Server operating systems are designed for multi-user environments and provide security, stability, and collaboration for applications like file sharing, web services, and email. Mobile operating systems control functions on devices like phones and tablets, with examples being Android and iOS.

Operating System Classification when two or more users can work with programs and share peripheral devices (printer, scanner, fax) multiple applications operated at the same time more than one CPUs that can be shared smaller parts of a program are loaded when needed by OS

System is a collection of programs which control the overall functions of which control the overall functions of computer. An operating system is a program that acts as an interface between the user of a computer and the computer hardware. The purpose of operating system is to provide an environment in which a user can execute programs in a efficient manner. Operating system also acts as a platform on which various application programs such as word processor and excel are executed.

An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware,[1][2] although the application code is usually executed directly by the hardware and will frequently make a system call to an OS function or be interrupted by it. Operating systems can be found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems include Android, BSD, iOS, Linux, OS X, QNX, Microsoft Windows,[3] Windows Phone, and IBM z/OS. All these, except Windows, Windows Phone and z/OS, share roots in UNIX. Presentation Regarding functions of operating systems and their working and other information regarding their uses and types.

Design of an Intelligent System for Improving Classification of Cancer Diseases

Mohamed Loey

The methodologies that depend on gene expression profile have been able to detect cancer since its inception. The previous works have spent great efforts to reach the best results. Some researchers have achieved excellent results in the classification process of cancer based on the gene expression profile using different gene selection approaches and different classifiers Early detection of cancer increases the probability of recovery. This thesis presents an intelligent decision support system (IDSS) for early diagnosis of cancer-based on the microarray of gene expression profiles. The problem of this dataset is the little number of examples (not exceed hundreds) comparing to a large number of genes (in thousands). So, it became necessary to find out a method for reducing the features (genes) that are not relevant to the investigated disease to avoid overfitting. The proposed methodology used information gain (IG) for selecting the most important features from the input patterns. Then, the selected features (genes) are reduced by applying the Gray Wolf Optimization algorithm (GWO). Finally, the methodology exercises support vector machine (SVM) for cancer type classification. The proposed methodology was applied to three data sets (breast, colon, and CNS) and was evaluated by the classification accuracy performance measurement, which is most important in the diagnosis of diseases. The best results were gotten when integrating IG with GWO and SVM rating accuracy improved to 96.67% and the number of features was reduced to 32 feature of the CNS dataset. This thesis investigates several classification algorithms and their suitability to the biological domain. For applications that suffer from high dimensionality, different feature selection methods are considered for illustration and analysis. Moreover, an effective system is proposed. In addition, Experiments were conducted on three benchmark gene expression datasets. The proposed system is assessed and compared with related work performance.

Introduction to Quality Improvement Essentials

Excellence Foundation for South Sudan

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024. He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution Class 9 Study Material pdf free download

Vivekanand Anglo Vedic Academy

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe. For more information, visit-www.vavaclasses.com
