LinuxCBT IPv4 Edition focuses exclusively on the established Internet Protocol Version 4 (IPv4) and its ancillary components: TCP, UDP, ICMP, ARP, etc.
The coursework explores IPv4 implementation on today's mainstream Network Operating Systems (NOSs), including: GNU/Linux, Windows and Cisco IOS.
IPv4 is the delivery mechanism that drives packets across the Internet, interconnecting a plethora of applications. Coupled with ancillary protocols, IPv4 enables a vast array of transactions to be conducted via: PCs, mobiles, etc.
LinuxCBT IPv4 Edition will prepare you and/or organization to understand the nuances of the key Internet protocol suite: TCP/IP.
Recommended Prerequisites for:
- Any LinuxCBT OS Edition such as LinuxCBT SLES-11 Enterprise Edition
- Open mind & determination to master Linux and related open-source applications
- Basic MS Windows skills
- Basic understanding of networking concepts
- Access to a PC to perform all of the installations and exercises
