Installing Computer Hardware
This topic covers installing computer hardware, including understanding reasons, risks, and precautions. Learners must be able to install, test, and document hardware installations or upgrades.
Assessment criteria
Topic Overview
The Cambridge OCR Level 2 Cambridge Technical Diploma in IT is a vocationally-related qualification designed to equip students with practical IT skills and theoretical knowledge essential for the modern workplace. This diploma covers a broad range of topics including computer systems, networking, cybersecurity, database management, and web development. Unlike purely academic qualifications, it emphasises hands-on learning and real-world applications, preparing students for apprenticeships, further study, or entry-level IT roles.
Students will explore how computer hardware and software work together, the principles of data storage and transmission, and the importance of secure systems. The course also develops problem-solving and project management skills through practical assignments. By the end of the diploma, learners should be able to configure networks, create databases, design websites, and understand the ethical and legal implications of IT use. This qualification is ideal for those who prefer a more applied approach to learning IT.
Key Concepts
Core ideas you must understand for this topic
- →Computer hardware components (CPU, memory, storage) and their functions within a system.
- →Networking fundamentals: types of networks (LAN, WAN), IP addressing, and protocols (TCP/IP, HTTP).
- →Database design and SQL: creating tables, querying data, and ensuring data integrity.
- →Cybersecurity principles: threats (malware, phishing), prevention methods (firewalls, encryption), and data protection laws (GDPR).
- →Web development basics: HTML, CSS, and the structure of a website.

Assessment Guidance
Guidance for achieving higher grades
- 💡Always follow anti-static procedures.
- 💡Test hardware immediately after installation.
- 💡Keep a log of all steps and any issues encountered.
- 💡Memorise the steps for safe hardware handling.
- 💡Practice installing common components like RAM and hard drives.
- 💡Use diagrams to explain installation sequences.
- 💡Always follow manufacturer's instructions.
- 💡Use anti-static wrist straps and mats.
- 💡Document step-by-step for future reference.
- 💡When answering questions about network topologies, always draw a labelled diagram to show connections clearly. This demonstrates understanding and can earn method marks.
- 💡For database questions, use correct SQL syntax and include primary and foreign keys in table designs. Examiners look for normalisation to at least 2NF.
- 💡In cybersecurity questions, refer to specific legislation (e.g., Computer Misuse Act 1990, GDPR) and explain how it applies to the scenario given.
Common Mistakes
Common errors to avoid in your coursework
- Not grounding themselves to prevent electrostatic discharge.
- Forgetting to back up data before installation.
- Incomplete documentation of the installation.
- Forgetting to power off and disconnect the system before installation.
- Not using anti-static precautions, risking component damage.
- Failing to test the hardware after installation.
- Not grounding themselves to prevent ESD.
- Forgetting to check compatibility of components.
- Skipping testing or documentation steps.
- Misconception: 'The CPU is the only component that affects computer speed.' Correction: RAM, storage type (SSD vs HDD), and GPU also significantly impact performance.
- Misconception: 'A firewall alone makes a network secure.' Correction: Security requires multiple layers, including antivirus, strong passwords, and user training.
- Misconception: 'SQL is only for retrieving data.' Correction: SQL also manages data (INSERT, UPDATE, DELETE) and defines database structure (CREATE, ALTER).
