FiSi-Training: IT Practice

Master IT networking through practice, not theory.

FiSi-Training: IT Practice is a hands-on learning app for networking fundamentals, designed for students and learners preparing for IT certifications such as CompTIA Network+ and CCNA-level topics.

Instead of passive videos or reading-heavy courses, you solve real interactive problems and get instant feedback.

What you practice

Train across 15 structured modules covering essential IT and networking skills:

• Binary, decimal, and hexadecimal conversions
• IPv4 subnetting and network calculations
• IPv6 subnetting and address structure
• Network IDs, broadcast addresses, and host ranges
• VLSM (Variable Length Subnet Masking)
• Public vs private IP addressing
• TCP/UDP ports and services
• OSI model and protocol layers
• Logic gates and digital fundamentals
• Truth tables and boolean logic
• Data transfer rate calculations
• Bandwidth and throughput conversions

Why this app works

Networking is not learned by watching. It is learned by solving.

This app turns core IT concepts into interactive problem-solving drills so you actually understand subnetting, addressing, and protocols instead of memorizing them.
