20+ year network engineer and programmer here.
Get a good CCNA study book (like Todd Lammle’s) and browse the first few chapters until you are satisfied. Stop when you don’t care about the chapter topics anymore.
Lammle’s book is highly-regarded and an easy read. It begins at layer 1 (electrical signals) and continues up the OSI stack.
You could even buy an old, used edition. The information you’re interested in hasn’t changed.
