### CS 142 — Computer Architecture and Organization

- **Units:** 3
- **Hours:** 54 Lecture
- **Prerequisite:** CIT 127
- **C-ID:** COMP 142
- **Transfers to:** CSU, UC
- **Offered:** Fall 2026, 1 section (/c/rio-hondo-college/schedule/fall-2026/cs.md)

Students are introduced to the organization and behavior of real computer systems at the assembly-language level. The mapping of statements and constructs in a high-level language onto sequences of machine instructions is studied, as well as the internal representation of simple data types and structures. Numerical computation is examined, noting the various data representation errors and potential procedural errors.
