Introduction to Networks
This course is designed to provide a full overview of computer networking. Knowing how to install, configure, and troubleshoot a computer network is a highly marketable and exciting skill. This course first introduces the fundamental building blocks that form a modern network, such as protocols, media, topologies, and hardware. It then provides in depth coverage of the most important concepts in contemporary networking, such as:
- TCP/IP
- Ethernet
- wireless transmission
- virtual networks
- security
- troubleshooting
After completing this course and completing the exercises, you will be prepared to select the best network design, hardware, and software for your environment. You will also have the skills to build a network from scratch and maintain, upgrade, troubleshoot, and manage an existing network. Finally, you will be well-prepared to pass CompTIA’s Network+ N10-007 certification exam.
Job Outlook
BLS Employment of network and computer systems administrators is projected to grow 5 percent from 2020 to 2030, slower than the average for all occupations.
Despite limited employment growth, about 24,900 openings for network and computer systems administrators are projected each year, on average, over the decade.
