Hardware and Networking Course

Master both hardware and networking from the ground up with a course built for people who want real, job-ready skills. You'll go from identifying PC components to configuring enterprise networks and locking them down against threats. Every module is packed with hands-on tasks that mirror what technicians and network admins do every day.

Dedika for businesses

What you will learn:

You'll learn how to identify, assemble, and troubleshoot PC hardware, then move into installing and managing operating systems across Windows and Linux. From there, you'll build a solid foundation in networking concepts, IP addressing, subnetting, and the OSI model. You'll configure routers, switches, and wireless access points, then set up essential services like DNS, DHCP, and VPN. The course also covers network security, including firewalls, ACLs, and endpoint hardening. By the end, you'll be prepared for entry-level IT roles and industry certifications like CompTIA A+, Network+, and Cisco CCNA.
