Explore fundamental network concepts, including network types, topologies, and switching; compare reference models, manage IP addressing and routing protocols, and cover DNS, NAT, and VPN technologies for beginners.
Explore how networks connect devices using media such as fiber, copper, Bluetooth, and satellites, and trace the evolution from sneaker network to LAN, MAN, WAN, and internet protocols.
Explore how physical and logical network topologies differ and summarize bus, ring, star, and mesh designs, including full and partial mesh, plus point-to-point and point-to-multipoint configurations.
Explore the OSI model and its seven layers from application to physical. Learn how standardization enabled interoperability across vendors and streamlined network design.
Explore the OSI model’s remaining layers—transport, network, data link, and physical—covering reliability, flow control, segmentation, encapsulation into packets and frames, and MAC/LLC addressing, plus the DCP model.
Master switching fundamentals at the data link layer by examining how frames are encapsulated, how mac addressing operates, and the roles of llc and mac sublayers, plus csma/cd concepts.
Explore unicast, broadcast, and multicast traffic and how collision domains and broadcast domains shape network segmentation using hubs, layer-2 switches, and department-based isolation.
A switch uses MAC address table to forward frames: broadcast to all ports when unknown or a broadcast address; otherwise forward to the known port; duplicates on port are dropped.
Explain IP addressing as 32-bit, four-byte decimal addresses with network and host parts, cover class a–e ranges and the distinction between public and private addresses managed by IANA and ICANN.
Explore how subnetting moves beyond classful addressing to create smaller networks, control broadcast domains, and apply routing and quality of service policies.
Explore static and dynamic routing within and between autonomous systems, contrast static entries with adaptive routing, and learn how IGP and BGP govern routing tables, next hops, and IP addressing.
Understand how DCP dynamically assigns IP addresses and network details, and compare DCP and UDP as transport layer protocols with DNS concepts and records (A, CNAME, MX, PTR).
Explore core networking concepts including private and public IPs, network address translation, and VPN types (site-to-site, remote access, extranet) with DNS and basic OSI layers.
