FCFS and SJF

CPU Scheduling in Operating Systems: In the context of operating systems, CPU scheduling involves determining which process (or task) should be executed next by the central processing unit (CPU). The goal is to maximize CPU utilization, minimize waiting time, and ensure fair allocation of resources. Various scheduling algorithms are used to achieve these objectives. First-Come-First-Serve (FCFS) Scheduling: Definition: FCFS is the simplest CPU scheduling algorithm. It is non-preemptive, meaning once a process starts executing, it cannot be interrupted until completion. Processes are placed in a queue based on their arrival time. The process that arrives first gets executed first. Execution Order : Processes are executed in the order they arrive. The process at the front of the queue is selected for execution. Advantages: Easy to implement. Minimal overhead. Disadvantages: Often results in long waiting times. Leads to the convoy effect (where a long process holds up other processes). Sh

Shared Memory Inter-Process Communication ( IPC)

Shared memory Inter-Process Communication (IPC) in Linux allows processes to communicate by sharing a region of memory. This method is efficient because it avoids the overhead of copying data between processes. Here's how shared memory IPC is typically done in Linux: Create a Shared Memory Segment: To use shared memory IPC, you need to create a shared memory segment. This is done using the shmget() system call, which allocates a new shared memory segment or obtains the identifier of an existing one. You specify the size of the shared memory segment and some permissions. Attach the Shared Memory Segment: Once you have obtained the identifier for the shared memory segment, you need to attach it to the address space of your process. This is done using the shmat() system call. This call returns the address of the shared memory segment in your process's address space. Accessing the Shared Memory: After attaching the shared memory segment to your process's address space, you c
