Description

There is no other topic that is synonymous with networking than the TCP/IP architecture model. It is the standard used to create all modern network infrastructure and global connectivity. TCP/IP model is the de facto standard that replaces older OSI reference model for all network connectivity today. The only difference is that TCP/IP model collapses upper layers into a single application layer.

In this course you will learn the fundamentals of network communications for all platforms including Cisco, Windows, Linux and cloud servers. Learn the different connection types, network addressing, services, communication protocols and PDU. TCP/IP is an architecture that is less rigid than the OSI model. Most applications today are web-based (HTTP) and deployed to public and private network domains. Any web browser on an endpoint can access web-based applications.

TCP/IP reference model replaces older OSI model.

  • Learn how data messages are sent across the internet

  • Learn the fundamentals of network communications 

  • Ethernet, ARP, Wireless, IP, TCP, UDP, DNS, HTTP

  • Linux, Windows, and Cisco IOS stack architecture

  • De facto standard that replaces older OSI model

TCP/IP architecture model is the current standard today for all network communications. In this course you will learn how network hardware, protocols and applications all work together to send data messages across the internet. Deepen your knowledge and understanding of networking and take your career to the next level with rarely available information.

You will learn how a network session is operational from the physical layer up to and including the application layer. There is an explanation of how applications and operating system plug-in to the communications stack as well. This is an essential course for network administrators, technical support, web/application developers and certification students.

Who this course is for:

  • Network administrators, data center analysts, and cloud engineers
  • Certification students (CCNA, CCNP, Network+)
  • Software developers
  • Anyone starting an I.T career
