Operating System
Introduction to Paging
Ram Kripal Operating System Gate, Operating System 0
Paging is a memory management scheme that allows non-contiguous allocation of processes, and which eliminates problems with fragmentation by allocating memory in equal sized blocks known as pages. The basic idea behind paging is
Introduction to Swapping Technique
Ram Kripal Operating System Gate, Operating System 0
A process must be loaded into memory in order to execute. If there is not enough memory available to keep all running processes in memory at the same time, then some processes who are
Introduction to Memory Management
Ram Kripal Operating System Gate, Operating System 0
Memory accesses and memory management are a very important part of modern computer operation. Every instruction has to be fetched from memory before it can be executed, and most instructions
Deadlock Detection and Recovery Algorithm
Ram Kripal Operating System Gate, Operating System 0
If a system does not employ either a deadlock-prevention or a deadlock-avoidance algorithm(for detail see Introduction to Deadlocks, Methods for Handling Deadlocks and Deadlock Avoidance Techniques), then deadlock situation may occur.
Deadlock Avoidance Techniques
Ram Kripal Operating System Gate, Operating System 0
Deadlock prevention algorithms, prevent deadlock by restraining how request can be made. for more details read Methods for Handling Deadlocks and Introduction to Deadlocks.
Methods for Handling Deadlocks
Ram Kripal Operating System Gate, Operating System 0
For introduction to deadlocks please refer to the Introduction to Deadlocks. In this post we discuss the methods to handle the deadlock.
Introduction to Deadlocks
Ram Kripal Operating System Gate, Operating System 0
In a multi programming environment, several processes may compete for a finite number of resources. A process requests resources, and if the resources are not available at that time, process enters in a waiting state.
CPU Scheduling Algorithms
Ram Kripal Operating System Gate, Operating System 0
CPU Scheduling is the basis of multi-programmed operating system. By switching the the CPU among processes, the operating system can make the computer more productive.
Introduction to Threads
Ram Kripal Gate, Operating System Gate, Operating System 0
A thread, sometimes called a lightweight process (LWP), is a basic unit of CPU utilization, it comprises a thread ID, a program counter, register
