About this course

This course explains networking fundamentals and how to build a small computer network and configure it from scratch, with practice in the Packet Tracer program. It starts with networking concepts, network devices and media, then types of networks and network topologies, and then you learn to download Packet Tracer and about network addresses. After that you go into the IPv protocol and converting an address between binary and decimal, then the subnet mask, subnetting and the subnet ID. Next you move to protocols, ports and connecting to the network, building a small network with a hub and a switch, using VLANs to isolate the network and filter traffic, a DHCP server to give IP addresses automatically, and a router to connect networks. The course suits every beginner who wants to understand networks and anyone heading into technical support or networking. You need no previous experience, as the explanation starts from the first concepts and continues with hands-on practice. By the end you will be able to design a small network, divide it, set it up and test it on the simulator.

Expected outcomes

Ability to design small networks using appropriate tools.
Mastery of subnetting.
Configuration and management of VLANs and DHCP servers.
Using Packet Tracer to simulate and test networks.
Understanding essential protocols and important ports for networking.

18 lectures

Introduction to Networking ConceptsDefines what a network is, how it evolved and how data moves across it, then explains its components and the TCP/IP model with its four layers and the protocols working in each.8:16
Network Devices (Nodes) and Networking MediaExplains network devices such as end devices, router, switch, hub and repeater and the role of each, then transmission media, wired and wireless, including copper, coaxial and fiber cables.10:20
Types of Networks and Network TopologyExplains network types such as PAN, LAN and MAN, and network topologies like Bus, Star, Ring and Mesh, and how data travels between devices in each layout.12:24
Packet Tracer and Network AddressingIntroduces Cisco's Packet Tracer for building and simulating networks, then explains network addressing, MAC versus IP addresses and how they differ, with an intro to IP address classes.20:02
How to Download Packet TracerWalks through downloading Packet Tracer from the Cisco Networking Academy platform, choosing the version that suits your system, then shows the program's interface and its sections.5:25
IPV4 ProtocolExplains IPv4 addresses and classes A, B and C, how the mask separates the network part from the host part, then the idea of subnetting and how it saves addresses.11:01
Convert IP Address from Binary to DecimalShows how to convert an IP address from binary to decimal using a bit-value table and summing the values, with worked examples, and why this matters for how routers and switches read addresses.12:05
Convert Decimal to BinaryShows how to convert an IP address from decimal to binary by repeatedly subtracting the largest fitting value from the bit table, with examples for each part of the address.8:19
Subnet Mask (Part 1)Explains the Subnet Mask, how it marks the network bits and host bits, how a device tells whether another device is on the same network, and how to calculate the number of usable hosts.14:03
Subnet Mask (Part 2)Continues the Subnet Mask topic by finding subnet boundaries, calculating the network identifier, broadcast address and number of usable hosts by converting the address and mask to binary.13:07
SubnettingExplains splitting a large network into subnets based on each office's address needs, how to choose the right mask, and how to calculate each subnet's boundaries and broadcast address.16:32
Subnet IDExplains how to derive the Subnet ID and broadcast address from any IP address and its mask by borrowing bits from the host part, with a step-by-step worked example.13:08
Protocols and portsExplains common protocols and their ports, such as HTTP, SMTP, POP3 and IMAP, and the role each plays in web browsing and in sending and receiving email.9:40
Network CommunicationsExplains two core network services: DNS, which translates a website name into an IP address and the steps involved, and DHCP, which assigns IP addresses to devices automatically.6:47
Build a small network with hub and switchA hands-on Packet Tracer lab building a small network of three PCs, first with a Hub and then a Switch, assigning IP addresses and masks and testing connectivity with ping.6:50
Using VLANA hands-on lab linking groups of devices through switches and isolating one network from the others with VLANs, using ping tests to show which networks can communicate and which cannot.14:03
Using DHCP server for automatic IP configurationA hands-on lab setting up a DHCP server in Packet Tracer with a defined address pool, switching devices from static IPs to automatic addressing, then testing connectivity with ping.7:04
Using RouterA hands-on lab connecting two different networks with a router: assigning an IP and mask to each interface and enabling it, adding a static route between the networks, then testing with ping.9:13
