Operating System And Network Programming

OS and Networking Programming: Parent child communication, Producer-Consumer problem, Fork, TCP and UDP client-server communication

Operation System

1. System calls for process management:

    Fork(): Create a child process
    Wait(): Wait for process to change 
    Sleep : Delay for a specified amount of time
    Pipe(): Create pipe
   

2. System calls related to shared memory and semaphores:

    shmget(): Allocates a system V shared memory segment
    shmat(), shmdt(): System V shared memory operations
    shmctl(): System V shared memory control
    semget(): Get a system V semaphore set identifier
    semop(), semtimedop(): System V semaphore operations
    semctl(): System V semaphore control operations
   

Networking

Socket Programming

    1. TCP Client and Server 
    
    2. UDP Client and Server

TCP Client

    Socket()
    Connect()
    Write()
    Read()
    Close()

TCP Server

     Socket()
     Bind()
     Listen()
     Accept()
     Read()
     Write()
     Read()
     Close()
