Official Computer Science Exam - BEPC Session 2022

This official Computer Science exam from the BEPC 2022 session is a complete national Cameroonian examination paper, provided with its detailed answer key. Designed for Form Four students, it evaluates competencies across the three domains of the official Computer Science curriculum.

Part 1: Microcomputer Architecture and Information Representation (8 marks)

• Exercise 1 - Microcomputer Architecture: The context involves opening a cybercafe. The student must define the concept of a peripheral, classify peripherals (input, output, input/output), identify antivirus software (Avast) from a list, explain the importance of updating antivirus software, and name electrical protection equipment (voltage regulator). This concrete scenario anchors knowledge in professional reality.
• Exercise 2 - Information Representation: Questions cover the definition of a file, common numeration systems (binary, octal, decimal, hexadecimal), and identifying the binary system as the data representation mode on the hard drive. These concepts are essential to understanding how a computer works.

Part 2: Digital Citizenship (5 marks)

• The text deals with the leak of Baccalaureate 2020 exam papers in Cameroon, involving students and OBC officials. A student, GGK, received and shared the papers via Telegram and WhatsApp. The candidate must define social networks and sanctions, identify positive uses and misuses of social media, explain the reasons for GGK's detention, cite applicable national laws (Penal Code, Cybersecurity Law), and propose responsible attitudes when receiving confidential documents. This relatable topic directly raises awareness among BEPC candidates.

Part 3: Introduction to Algorithms and Software Development (7 marks)

• Exercise 1 - Algorithms: The "produit" algorithm calculates the product of two numbers. The student must define the term instruction, identify input and output instructions, and complete an execution table. This exercise develops the ability to manually simulate an algorithm.
• Exercise 2 - Software Development: Questions address the software lifecycle, the prototype approach (illustrated by the Dev-Software company scenario), and stakeholders in the requirements specification.

This BEPC 2022 exam paper is an essential preparation tool, featuring topics rooted in Cameroonian current events and a complete answer key for independent and effective revision.
