2026 Mock GCE: Computer Science Paper 1 & 2 Revision Guide
Welcome back, colleagues and students. As we prepare for the upcoming examination cycle, digitizing and organizing our marking guides and question papers is essential for effective revision.
Below is the formatted content from the March 2026 South West Regional Mock, covering key concepts from Operating Systems to Project Management.
Part 1: Theory & Systems (Paper 2)
1. Operating Systems & Storage
-
Defining the OS: What is an Operating System, and what are its two primary functions?
-
Storage Media Classification: Complete the table below by identifying the technology and access method (Sequential vs. Direct).
| Memory Device | Technology Used | Access Method |
| Magnetic Tape | Magnetic | Sequential |
| Flash Drive | Solid State | Direct |
| Solid State Drive (SSD) | Solid State | Direct |
| CD-RW | Optical | Direct |
2. Software & The Machine Cycle
-
Application Software: Identify software for calculations (e.g., Spreadsheet) and certificate design (e.g., Desktop Publishing).
-
The Machine Cycle: Explain the stages (Fetch, Decode, Execute, Store) with a detailed diagram.
3. Cloud Computing
-
Definition: An explanation of on-demand availability of computer system resources.
-
Services: Common models like SaaS (Software as a Service) and IaaS (Infrastructure as a Service).
Part 2: Algorithms & Programming
A teacher requires a program to calculate the average of two test marks ($Avg = (T1 + T2) / 2$) and determine a pass/fail status (Pass $\geq$ 10).
Key Definitions:
-
Source Code vs. Object Code: The human-readable instructions versus the machine-executable binary.
-
Variables: Named memory locations (T1, T2, Avg).
-
Data Types: Identifying the most suitable type for marks (Integer or Float/Real).
Part 3: Logic & Digital Media
Logic Gates
You should be able to sketch and label the inputs and outputs for:
-
XOR
-
NAND
-
NOR
Image Representation
Understanding how black and white images are stored:
-
Bitmapping: 1 bit per pixel (1 for Black, 0 for White).
-
Memory Mapping: How pixels are stored row-by-row in specific memory locations.
Paper 1: Mark Guide & Explanations (Multiple Choice)
| Q# | Correct Answer | Key Concept |
| 1 | C. LAN | Covers small areas like classrooms. |
| 2 | D. Intellectual Property | Ethics regarding copyrights and patents. |
| 3 | A. M2M Communication | How IoT devices interact without human input. |
| 4 | C. Binary | The only language understood at the hardware level. |
| 5 | C. Algorithm | A step-by-step procedure for solving a problem. |
| 6 | B. Truth Table | A list of all input combinations and outputs. |
| 7 | B. Project Management | Planning, organizing, and controlling resources. |
| 8 | C. Mouse | Standard pointing device for cursor control. |
