In the Cisco learning system, CCNA tutorials come either as interactive online tutorials or CD-ROM instructions. These give details of the basics of particular topic, and provide hands-on application through lab work.
CCNA Tutorials encompass five major topics: IP addressing, Subnetting, Routing Fundamentals, Cisco Access Control, and Networking Media.
We have heard of the network-node identifier consisting of binary digits. These digits represent the IP (Internet Protocol) address. An IP address has 32 binary bits in 4 dotted decimal notations with bits of 8 each.
A dotted decimal notation identifies by 0 to 255 ranges of decimal values. IP address identification is composed of five network classes from A to E.
Under Subnetting, students will learn to classify a subnet, compute for IP network addressing, classify classified addressing, and subnet IP network. Subnetting ought to systematize IP networking and routing, including the
utilization of corporeal media (such as WAN or LAN) and stopgap network shifts.
On the other hand, Routing Fundamentals includes RIP (Routing Information Protocol), OSPF (Open Shortest Path First), and IGRP (Interior Gateway Routing Protocol). RIP is a remote vector which computes via hop
count the integral routing based. IGRP, on the other hand, does mathematical comparisons for autonomous system routing while OSPF links the sending of packets within an IP network.
Thirdly, Cisco Access Control List (ASL) comes in two types: Standard Access and Extended Access. ACL serves as a filtering medium to packets under a given criterion on router interface.
Last on the list is the Networking Media. Basically, this is composed of LAN (Local Area Networks) and WAN (Wide Area Networks) adopted for digital communication. Both LAN and WAN have sub-categories that fall under each of them. The LAN communication routine is shared and uses higher speed, whereas WAN serves low speed point-to-point routines.
After accomplishing the tutorial topics, the skills of the students will be honed further if they focus on hands-on application via lab work.
