Introdution Generally, file resources when shared as read-only, never lead to deadlock condition. Definition The deadlock is a situation of an operating system in which no process is blocked and no process proceeds. A deadlock is a situation where each of the computer processes waits for a resource that is Read more…

Introduction Effective I/O management is crucial and necessary for system performance, as slow or inefficient I/O operations can significantly impact overall system responsiveness and throughput. The operating system is responsible for managing the I/O operations efficiently and providing a unified interface for applications to access these devices. Definition Input/output (I/O) Read more…

FILE MANAGEMENT Introduction Typically, files in a file system are organized and associated with several file attributes, including the file name, size, creation and modification timestamps, permissions, and file type. These attributes provide detailed information about the file and determine how it can be accessed and manipulated. In file management, Read more…

Disk Management Definition Disk management refers to the process of organizing, partitioning, formatting, and managing storage devices such as hard drives, solid-state drives (SSDs), and other storage media.  Characteristics Different operating systems provide various built-in tools and utilities for disk management, which are briefly discussed below – Windows: Windows operating Read more…

Introduction Memory management is a complex technique that is solved using various memory management algorithms and techniques employed by operating systems to optimize memory usage. The different memory management techniques vary depending on the operating system and hardware architecture. Effective memory management is very crucial for the overall performance, stability, Read more…

Terminology CPU Utilization: CPU Utilization is making the CPU is busy all the time, so that all the associated components of the system also utilized high. The maximum CPU utilization makes the system performance high. In another words, CPU utilization is the ratio of busy time of the processor to Read more…

DOS Click this link for DOS UNIX UNIX operating systems are used in widely-sold workstation products from Sun Microsystems, Silicon Graphics, IBM, and a number of other companies. The UNIX environment and the client/server program model were important elements in the development of the Internet and the reshaping of computing as Read more…
