Course Description

The free online course Diploma in Computer Networking introduces the key devices found on local area networks (LANs), explains the structure and function of different types of LANs and WANs, and introduces you to the network architecture and protocols used in network security.

The course begins by introducing you to the key devices found on LANs such as hubs, switches and routers, and how each of these devices functions to allow for effective and efficient communication on the LAN. You will then learn about the functions of IP addresses and how they are broken down into Network ID and Host ID components. The course then moves on to explain the seven layers of the OSI Model. You will learn about the structure and function of each layer and how data is passed through the seven layers to allow two devices communicate with each other.

You will learn about the structure of Internet Protocol addresses in detail, including IP Ranges and thei...

The free online course Diploma in Computer Networking introduces the key devices found on local area networks (LANs), explains the structure and function of different types of LANs and WANs, and introduces you to the network architecture and protocols used in network security.

The course begins by introducing you to the key devices found on LANs such as hubs, switches and routers, and how each of these devices functions to allow for effective and efficient communication on the LAN. You will then learn about the functions of IP addresses and how they are broken down into Network ID and Host ID components. The course then moves on to explain the seven layers of the OSI Model. You will learn about the structure and function of each layer and how data is passed through the seven layers to allow two devices communicate with each other.

You will learn about the structure of Internet Protocol addresses in detail, including IP Ranges and their classes. You will compare and contrast the structure and function of IPv4 and IPv6 addresses and will learn about the role of Default gateway and DNS server in networking. The course introduces you to basic TCP/IP tools such as command prompt, ipconfig and ping, and the use of these tools will be demonstrated. Next, you will be introduced to advanced TCP/IP tools such as Netstat, Pathping, Nslookup, Telnet, NbtStat and Netsh. Again, these tools and their uses will be demonstrated.

Next, you will learn about Dynamic Host Configuration Protocol, which is a client/server protocol that enables configured client computers to obtain IP addresses automatically. You will also learn about Internet Protocol Security (IPSec) which is a protocol within the TCP/IP suite that encrypts and authenticates IP packets. You will learn about Routing which is the process of managing the flow of data between network segments and between hosts or routers. You will review common dynamic routing protocols such as Distance vector routing (Routing Information Protocol (RIP) and Link state routing (Open Shortest Path First (OSPF)).


Next, the courses introduces the features and functions of VPN protocol: Point-to-Point Tunneling Protocol (PPTP). You will learn how Point-to-Point Tunneling Protocol (PPTP) encapsulates Point-to-Point (PPP) frames into IP datagrams for transmission over an IP-based network. You will then learn about Firewalls which are the most commonly used type of security device in an organization's perimeter and how they protect a network from malicious attack and unwanted intrusion.

You will learn about the two types of Packet filtering (Stateless and Stateful) and their functions. Finally, you will learn about the Network Intrusion Detection System (NIDS) which detects malicious network activities by monitoring network traffic, and the Network Intrusion Prevention System (NIPS) which inspects network traffic and can remove, detain or redirect malicious traffic.

This course will be of interest to all learners who would like to learn more about computer networking, the different types of LANs and WANs found in networks, the protocols used to allow secure communications between networks and network architecture and protocols used in network security. It will also be of great interest to all learners who are considering computer networking as a career or who are considering doing professional computer networking exams.
