Learn how the TCP/IP protocol suite enables guaranteed delivery with a TCP three-way handshake. Compare with UDP's delivery, and see how headers and encapsulation route data between client and server.
Explore how tcp and udp differ, with tcp guaranteeing delivery using sequence and acknowledgment numbers, windowing, and layered encapsulation, while udp favors speed for rapid data.
Explore how unicast, broadcast, multicast, and anycast traffic work, and learn how ARP builds IP-to-MAC mappings to enable communication between devices.
Learn how ping requests and echo replies traverse networks using ICMP, IP headers, MAC addresses, and default gateway routing, with Wireshark exposing encapsulation across layers.
Understand end-to-end communication in Cisco networks by tracking how switches and routers use layer 2 mac addresses and layer 3 ip addresses, changing macs at each hop.
Explore network types from personal area networks to local, metropolitan, and wide area networks, including the cloud, and compare switches, hubs, and routers across layer two and layer three.
Explore how a switch uses a MAC address table to forward frames only to the destination port, reducing collisions and enabling full duplex compared to a hub.
Explore how a local area network forwards data from the edge using layer 2 switches and MAC addresses to a router via the default gateway.
Explore how broadcast domains and collision domains shape local networks, showing how routers limit broadcasts, switches isolate collisions, and MAC addresses identify devices on a 48-bit hex scheme.
This is the last 2 course of the series Networking Fundamentals. Here we immediately go into the basics of Network types and LAN devices. Next we cover communication over the LAN.
You will learn about the basics of what a LAN is, what devices we will be using, and the ability to see LAN Networking in a different manner. We learn about CSMA/CD, Half & full Duplex, Collison & Broadcast Domains,how Mac address tables are created, and so on . You will learn where a router and a switch fits in the Network. You will also learn about what pins are used to transmit and receive.
It is a lot of fun, let's get started.
