Simulation and Modeling Technique - What is Simulation ? 

A simulation is the imitation of the operation of a real-world process or system over time.  It involves the generation of an artificial history of a system, and the observation of that artificial history to draw inferences. We discuss about simulation and modeling step by step.

IP Address in Networking

 IP Address in Networking :

Each computer in a TCP/IP network must be given a unique identifier, or IP address. This address, which operates at Layer 3, allows one computer to locate another computer on a network. All computers also have a unique physical address, which is known as a MAC address. These are assigned by the manufacturer of the NIC.
