What Tech Cards Does
Flashcard-style explanations of technology concepts — from HTTP to hash tables — for interview prep and everyday curiosity.
One idea per card: a definition, a diagram, and a memorable example.
Sorting, trees, graphs, and hash tables, minus the textbook fog.
HTTP, DNS, TLS, and what actually happens when a page loads.
Indexes, transactions, and joins as one-minute cards.
Curated decks matching what technical interviews actually ask.
One random card a day keeps the fundamentals fresh.
How Tech Cards Works
Choose a topic deck — algorithms, networking, databases — or an interview prep set.
Each card is a single concept with a diagram and example, built for spaced repetition.
The daily shuffle resurfaces old cards right before you'd forget them.
