CCNA: Computer Networking Essentials

Packt via FutureLearn


Prepare for a future in computer networking

As technology advances, the need for network professionals continues to grow. This three-week course will equip you with the necessary skills to develop and maintain computer networks at an industry level.

Gain the skills to pass the CCNA exam

One of Cisco’s most sought-after certifications, a CCNA qualification will demonstrate your ability to perform an entry-level job in computer networks.

On this course, you’ll learn the more advanced concepts required to pass the CCNA exam, building on the knowledge you already have of networking layers, routing, and TCP/IP and OSI models.

By gaining a CCNA certificate, you can prove to prospective employers that you have the skillset to excel in the computer network sector.

Examine computer network protocols

Network protocols are the rules that determine how data is transmitted between devices that share a network.

On this course, you’ll explore intermediate protocols including Address Resolution Protocol (ARP), User Datagram Protocol (UDP), and Dynamic Host Configuration Protocol (DHCP).

By understanding these protocols, you’ll be able to explain the more complex processes within computer networks and improve your IP management skills.

Enhance your understanding of network routing

Routing is the process of mapping paths so that your data can travel from its source to your chosen destination.

On this course, you’ll explore this concept in detail, from the responsibilities of router hardware to managing multiple route paths.

With this knowledge, you’ll be able to understand the routing protocols involved in small, individual networks up to global organisations.

By the end of this course, you’ll have gained essential knowledge of computer networks in preparation for the CCNA exam and a future career in networking.

This course is designed for those with an interest in computer networks who already have a foundational understanding of network processes. It is particularly useful for those preparing to take the CCNA exam.

You’ll need a MacOS or Windows computer running Wireshark, which is free to download.
