Networking is the practice of connecting computer devices together to support communication among
them. Overview – Communication Protocols – Transmission Media – Networking Devices
An IP address is a unique identifier of a computer on the network and on the Internet. Overview – IPv4 – Classes of IP address – Network Portion – Host Portion – Subnet Mask
Subnetting is the process of dividing an IP network into smaller networks called Subnets. Overview – Importance of Subnetting – Subnet zero – Importance of Subnet Mask – Classful / Classless addressing – VLSM
Routing is the act of moving data across an internetwork from a source to a destination.
Overview – Understanding the Routing Table – Static Routing – Default Routing – Fast Switching – CEF
When a host transmits data across a network to another device, data is encapsulated with several headers and trailers.
Overview – OSI Model – Encapsulation – Decapsulation – Connection Oriented / Connectionless Protocol
Router Boot Preferences – CLI – Console / VTY Login – Telnet – SSH – Password Protection – Password Recovery – Syslog – NTP – SNMP – Net Flow – Backup & Restore
Dynamic routing is the process of learning routing information automatically with the help of routing protocols.
Overview – Classes of routing protocols – RIP – IGRP – EIGRP – OSPF – Route summarization – Route
Redistribution – Load Balancing

Packet filtering is a network security mechanism that works by controlling which data can flow to and from a network
Overview – Access Control Lists – Standard ACL – Extended ACL – Named ACL – Log Options
Network address translation (NAT) allows a router to modify packets to allow for multiple devices to share a single public IP address
