The variations and differences in the nature of different operating systems may give the impression that all operating systems are absolutely different from each-other. But this is not true.
All operating systems contain the same components whose functionalities are almost the same.
For instance, all the operating systems perform the functions of storage management, process management, protection of users from one-another, etc.
The procedures and methods that are used to perform these functions might be different but the fundamental concepts behind these techniques are just the same.
Operating systems in general, perform similar functions but may have distinguishing features.
Therefore, they can be classified into different categories on different bases.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Computer System Structure
Computer system is mainly divided into four
components:
• Hardware
Memory, CPU and I/O devices
• Operating system
Coordinates and controls the use of hardware
• Application programs
Word processors, web browsers, compilers, database
systems and video games
• Users
Machines, people and other computers

Operating System:
Viewpoints
Operating System can be understood by following point
of views:
User View
System View
• USER VIEW
User emphasizes on ease of use, convenience, little on performance
and none to resource utilization
• SYSTEM VIEW
Resource allocator - Hardware and Software
Control Program – Manages the execution of user programs(errors
and improper use)

Operating System Structure
Layered Approach
01/19/17 17
Operating System is divided or broken down into levels (layers)
Built on top of lower layer
The bottom layer (lower layer 0) is hardware and the highest layer is the
user interferences
The Data Structures and a set of routines at the top layer can invoke
operations on lower layer
Each layer hides some operations, certain data structures and hardware
from higher level layers
