The document summarizes key concepts in internetworking including protocol layering, encapsulation, and different types of network devices like hubs, bridges, and routers. It describes how the Internet Protocol (IP) allows interconnection of different networks by providing a global addressing scheme and best-effort delivery of packets across interconnected networks.
In Computer Networking, the term port can refer to either physical or virtual connection points. In
computer terms, a port generally refers to the female part of connection. Computer ports have many
uses, to connect a monitor, webcam, speakers, or other peripheral devices.
Advanced TCP/IP-based Industrial Networking for Engineers & TechniciansLiving Online
This manual is for engineers and technicians who need a practical and extensive knowledge of the design and troubleshooting of Industrial Ethernet networks, as well as the selection, installation, and configuration of components such as routers and switches.
It deals in-depth with the underlying TCP/IP protocols, and specifically addresses both design and configuration issues related to IPv4 and the more recent IPv6.
It also covers the more advanced aspects and applications of Ethernet such as advanced switching and routing, CCTV over IP, OPC and Modbus/TCP over Ethernet, industrial security, intrinsically safe applications, switched rings (included the latest IEC 62439-3 redundant ring standard), and highly-deterministic Ethernet-based field buses (e.g. for servo control) capable of 1 millisecond repetition rates and jitter of less than 1 microsecond.

Adhoc mobile wireless network enhancement based on cisco devicesIJCNCJournal
Adhoc wireless networks become one of the most researchable areas in the studying of routing protocols depending on the Open System Interconnection (OSI Model). This paper use Cisco devices as a reference to enhance the performance of the network. This enhancement will be due to high processing, reliability, average cost, power consumption and accessibility. The aim of this research not only to get the cost down, it also to choose a time to time device to process the data as rapid as it can. Using NAT, Access List and DHCP protocols defined in Cisco (Graphical Unit Interface) GUI of the (Command Line Interface) CLI, the task can be made.
