Networking Models & Layered Architecture
Lesson 1: OSI Reference Model Topics: 7-layer OSI model: role and functionality of each layer Objectives: Describe the purpose of each OSI layer Lesson 2: TCP/IP Model Topics: 4-layer TCP/IP model, protocol mapping to OSI Objectives: Compare OSI and TCP/IP; explain how internet protocols fit in

Physical and Data Link Layers
Lesson 1: The Physical Layer Topics: Transmission media, bandwidth, modulation, cables, wireless signals Objectives: Describe how data is physically transmitted Lesson 2: Data Link Layer & Ethernet Topics: MAC addresses, framing, switches, ARP, Ethernet standards Objectives: Explain how data is prepared and sent over local links

Network Layer
Lesson 1: IP Addressing and Subnetting Topics: IPv4 structure, classes, subnet masks, CIDR Objectives: Calculate subnets and assign IPs to devices Lesson 2: Routing and Routers Topics: Routing concepts, static vs dynamic routing, RIP, OSPF Objectives: Understand how routers forward packets and find paths

Transport Layer
Lesson 1: TCP and UDP Topics: Reliable vs unreliable delivery, handshaking, ports, segmentation Objectives: Distinguish between TCP and UDP protocols Lesson 2: Flow and Congestion Control Topics: Windowing, ACKs, sliding window, TCP congestion algorithms Objectives: Understand how transport layer controls traffic and errors

Application Layer Protocols
Lesson 1: DNS, HTTP, and Email Topics: DNS resolution, HTTP/HTTPS, SMTP/POP/IMAP Objectives: Explain how the internet retrieves domain and web content Lesson 2: Web and File Transfer Protocols Topics: FTP, Telnet, SSH, SNMP basics Objectives: Use command-line tools to connect to remote services
