Operating System Tutorial
Interrupts in Operating System (OS) Interrupts are signals or events that divert the attention of the central processing unit (CPU) from its current task to handle a specific event. These events can range from hardware-related issues, such as a keypress or mouse movement, to software-generated signals like system calls or program errors. Interrupts allow the …
File Systems in Operating System (OS) A File system is responsible for organizing data into files and directories, allowing users and applications to locate, access, and manipulate information efficiently. It acts as a bridge between the user and the physical storage media, providing a logical structure for data storage. In the below PDF we discuss …
Segmentation in OS (Operating System) Segmentation is a memory management technique that divides a computer’s primary memory into distinct segments or sections. Each segment is dedicated to a particular task or type of data, allowing for better organization and management of memory resources. Unlike the more traditional memory management approach of a single contiguous block, …
Paging in OS Paging is a memory management scheme used by operating systems to enable efficient utilization of physical memory. The fundamental idea behind paging is to divide the physical memory into fixed-size blocks, known as “pages,” and the logical memory into corresponding-sized blocks called “frames.” These pages act as the smallest unit of data …
Fragmentation in OS Fragmentation is an undesirable condition that occurs in an operating system when a process is unloaded and loaded from memory, causing the free memory space to become fragmented. As a result, the process cannot be assigned to the memory blocks since they are so small. In the area of operating systems, fragmentation …
Virtual Memory in Operating System Virtual memory is a memory management technique that provides an illusion to users and applications, making them believe that the system has more physical memory (RAM) than it actually possesses. This illusion is achieved by combining both RAM and a portion of the computer’s storage, typically the hard drive or …
Memory Management In Operating System Memory management is a critical aspect of Operating systems (OS) that plays a pivotal role in ensuring efficient utilization of a computer’s resources. In essence, it is the process of controlling and coordinating computer memory, allowing applications and the OS itself to access the necessary data and instructions. This blog …
Process Synchronization in OS Process synchronization refers to the coordination and control of the execution order of processes in a concurrent system. In a multitasking environment, multiple processes often share resources, such as memory, files, and input/output devices. Without proper synchronization, conflicts can arise when multiple processes attempt to access or modify shared resources concurrently, …
Process Management In Operating System A Process is an instance of a computer program that is being executed by one or many threads. It contains the program code and its current activity. A process may create and manage multiple threads of execution, each executing independently and concurrently, but belonging to the same process. Process management …
Types of Operating Systems An operating system is a set of software that acts as an intermediary between computer hardware and the applications or programs running on it. It serves as a bridge, enabling communication and coordination between various hardware components and ensuring efficient use of resources. In the below PDF we discuss about Operating …
