A major portion of the board paper tests your ability to predict code outputs. Pay close attention to Preeti Arora's dedicated chapters on "Finding Errors" and "Predicting Outputs."
Here's a valuable treatise on the topic:
Modem, RJ45 connector, Hub, Switch, Gateway, Router, and Repeater.
: Most free PDFs floating online belong to older academic years. CBSE frequently updates its syllabus weightage and introduces new question typologies (such as Assertion-Reasoning and Case-Based questions). Relying on an old digital copy might leave you unprepared for the current exam pattern. SQL commands (DDL, DML)
