Network Socket Programming using TCP in C

1.0 Client-server model

Client - Server System

Client server model is a software architecture paradigm prevalent in distributed applications. A server has information resources and processes that provide answers to queries and other services to remote clients over the network. Some of the examples of these services are booking an airline ticket and/or a room in a hotel, sending a file to a client, sending a mail message to another person (client), etc.… Read more “Network Socket Programming using TCP in C”

Signals in Linux

Signals are software interrupts that are delivered to a process by the kernel. A signal indicates that an event has occurred and the process must take note of it. A signal is delivered asynchronously to a process. Whatever the process was doing is suspended and the processing of the signal takes place immediately.… Read more “Signals in Linux”

Interprocess communication using System V Shared Memory in Linux

Shared memory

1.0 Shared Memory

Shared memory is one of the three interprocess communication (IPC) mechanisms available under Linux and other Unix-like systems. The other two IPC mechanisms are the message queues and semaphores. In case of shared memory, a shared memory segment is created by the kernel and mapped to the data segment of the address space of a requesting process.… Read more “Interprocess communication using System V Shared Memory in Linux”
