In computing, GINA refers to the graphical identification and authentication library, a component of some Microsoft Windows operating systems that provides secure authentication and interactive logon services.

Tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis or debugging. A program like 'tcpdump' shows a summary of packets seen on the wire, but usually doesn't store the data that's actually being transmitted. In contrast, tcpflow reconstructs the actual data streams and stores each flow in a separate file for later analysis.

Denial-of-service (often abbreviated as DoS) is a class of attacks in which an attacker attempts to prevent legitimate users from accessing an Internet service, such as a web site.This can be done by exercising a software bug that causes the software running the service to fail (such as the “Ping of Death” attack against Windows NT systems), sending enough data to consume all available network bandwidth (as in the May, 2001 attacks against Gibson Research), or sending data in such a way as to consume a particular resource needed by the service.

Address Resolution Protocol (ARP) a stateless protocol was designed to map Internet Protocol addresses (IP) to their associated Media Access Control (MAC) addresses.

This being said, by mapping a 32 bit IP address to an associated 48 bit MAC address via attached Ethernet devices, a communication between local nodes can be made.
