Introduction to Networking

This eight-hour, hands-on course provides IT and security teams with a practical introduction to computer networking.

On-Demand $295.00

Course Length: 8 Hours

Includes a Certificate of Completion



Description

This eight-hour, hands-on course provides IT and security teams with a practical introduction to computer networking. Participants will explore how devices communicate using TCP/IP, how packets move across networks, and how protocols like ARP, IP, TCP, UDP, and DNS operate. Guided labs using Wireshark allow students to observe real packet captures and understand how networking works in practice.

Syllabus

Foundations of Networking

  • What a network is and how devices communicate

  • LANs, WANs, and the global internet

  • The history and development of internet protocols

Communication Protocols

  • How protocols define structured communication

  • RFCs and the development of internet standards

  • Protocol layering concepts

The TCP/IP Model

  • The relationship between the OSI model and TCP/IP

  • Application, Transport, Internet, and Link layers

  • How messages travel down and up the protocol stack

Binary and Numbering Systems

  • Binary representation of data

  • Bits, bytes, and hexadecimal values

  • Why number systems are essential to networking

Network Addressing

  • MAC addresses and hardware identification

  • IP addresses and logical network location

  • Address Resolution Protocol (ARP)

Internet Protocol

  • IPv4 and IPv6 fundamentals

  • Packet structure and header fields

  • Routing packets between networks

Transport Protocols

  • TCP connection management and the three-way handshake

  • UDP communication and low-overhead messaging

  • Ports and service identification

Network Services

  • Dynamic Host Configuration Protocol (DHCP)

  • Domain Name System (DNS)

  • Network Address Translation (NAT)

Network Security Foundations

  • Why the original internet protocols lacked security

  • Common implications for modern cybersecurity defenses
