  1. 01

    Digital information

    • Use bits, bytes, binary numbers, text, images, and compression.
    • Explain limits of digital representation.

    Practice: Convert numbers between binary and decimal and explain one compression tradeoff.

  2. 02

    The Internet

    • Explain protocols, packets, IP addresses, DNS, routing, bandwidth, and latency.
    • Describe fault tolerance and network tradeoffs.

    Practice: Trace a web request from browser to server using protocol vocabulary.

  3. 03

    Programming foundations

    • Use variables, expressions, conditionals, loops, procedures, and lists.
    • Trace programs with AP CSP pseudocode rules.

    Practice: Write a small program and trace it with a table of variable values.

  4. 04

    Algorithms

    • Express, compare, and verify algorithms.
    • Use sequencing, selection, iteration, and complexity reasoning.

    Practice: Compare two algorithms for the same task and justify correctness and efficiency.
