Topics covered in O Level Computer 10
Algorithm Design & Problem-Solving
Decomposition and abstraction, flowcharts and pseudocode, searching and sorting, validation and testing. Paper 2 begins here and most of its marks are for method.
Programming
Variables and data types, the three constructs in pseudocode, arrays, sub-programs and file handling, the topic where the Paper 2 program is written.
Data Representation
Binary, hexadecimal, binary addition and shifts, and how text, images and sound are stored, a topic of conversions where the method must be shown.
Data Transmission
Packets, serial and parallel, simplex to full-duplex, error checking and encryption, a topic where each method must be paired with what it detects or prevents.
Hardware
The CPU and its registers, the fetch-decode-execute cycle, memory, storage and embedded systems, the topic where naming the register in the right order is the mark.
Software
System and application software, the operating system, interrupts, and translators, a topic of clean distinctions that the paper tests directly.
The Internet & Its Uses
How a page reaches your browser, HTTPS and certificates, cyber threats and the measures against them, the section where every threat must be paired with a specific defence.
Automated & Emerging Technologies
Sensors, microprocessors and actuators in closed-loop control, plus robotics, AI and extended reality, a short topic that rewards a precise control-loop description.
Databases
Records, fields and keys, flat file versus relational, data types and validation, and SQL, the topic where a query must be written, not described.
Boolean Logic
The six gates, truth tables, logic expressions and circuits, the most mechanical topic on the paper, and the easiest place to be certain of full marks.
