In operating systems, effective and reliable synchronization mechanisms play a vital role in managing concurrency and coordinating the activities of multiple processes or threads. Two essential tools for synchronization are lock variables and turn variables, each serving distinct purposes and having unique characteristics. In this article, we will explore the key differences between lock variable and turn variables...
In computing, a named pipe (also known as a FIFO) is one of the methods for inter-process communication....
Temporary data like as method/function arguments, return address, and local variables are stored on the process Stack, whereas on the other hand, the CPU stack consists of a collection of data words. It employs the Last In First Out (LIFO) access technique, which is the most common in most CPUs. In this article we are going to find out the detailed difference between both of these....
1. Priority Inheritance Protocol (PIP) :
Priority Inheritance Protocol (PIP) is a critical resource sharing protocol which is used for sharing critical resources among different tasks. This allows the sharing of critical resources among different without the occurrence of unbounded priority inversions. When a task goes through priority inversion, the priority of the lower priority task which has the critical resource is increased by the priority inheritance mechanism. It allows this task to use the critical resource as early as possible without going through the preemption. It avoids the unbounded priority inversion....
In operating systems, Memory Management is the function responsible for allocating and managing a computer’s main memory. The memory Management function keeps track of the status of each memory location, either allocated or free to ensure effective and efficient use of Primary Memory....
RAID 0 stands for Redundant Array of Independent Disks 0. RAID 0, also known as disk stripping, Disk Stripping is the technique of breaking data into multiple blocks and storing those blocks on several storage disks. A minimum of 2 disks are used in RAID 0. RAID 0 does not provide data redundancy and therefore may be used for temporary storage of data where the original data is recoverable from any other storage device....
1. AIX :
AIX is a series of proprietary operating systems which is provided by IBM. AIX stands for Advanced Interactive eXecutive. Initially it was designed for the IBM RT PC RISC workstation and later it was used for various hardware platforms like IBM RS/6000 series, PowerPC-based systems, System-370 mainframes, PS-2 personal computers and Apple Network Server. It is one of the five commercial operating systems that have versions certified to UNIX 03 standard of The Open Group. The first version of AIX was launched in 1986. The latest stable version of AIX is 7.2....
1. iOS :
iOS is a mobile operating system which is provided by Apple Incorporation. It is mainly designed for Apple mobile devices like iPhone and iPod Touch. It was earlier known as iPhone OS. It is a Unix-like operating systems which is based on Darwin(BSD) operating system. It is the world’s second most used mobile operating system after Android. It is mainly written in C, C++, Objective-C, assembly language and Swift. The first version of iOS was launched in 2007....
1. Android 1.0 :
Android 1.0 is the very first version of Android which was introduced by Google. It had some basic features including web browser support, camera support, Gmail accounts, Google maps and Youtube application. Although it does not have the official version name like further introduces versions but unofficially it is called Apple Pie. The API level in Android 1.0 version is 1. It is not used anymore in the mobile devices. It was released on 23 September 2008....
macOS is built on a Unix based architecture and provides users with a reliable and user friendly experience. In this article, we will understand macOS in detail....
I/O Interlocking is an important player in the field of operating systems because it guarantees safe and efficient communications between the CPU and different I/O devices. More details are coming up....
The Synchronization is an important concept in operating systems that ensures the smooth and coordinated execution of processes and threads. It is the task of coordinating the execution of processes in such a way that no two processes can access the same shared data and resource. It is a critical part of operating system design which ensures that processes or threads can safely share resources without interfering with each other. Synchronization is important because it helps in avoiding Data inconsistency between multiple processes or threads, Deadlocks and Race conditions. It is generally used in multi-processing systems, where process concurrently attempt to access the same shared resource of piece of data....
