Assessment criteria
Quick Revision Summary (Key Takeaway)
The City & Guilds Level 2 Award in ICT Systems and Principles covers the fundamental hardware, software, networking, and security concepts required for entry-level IT support roles. This qualification focuses on practical understanding of computer systems, including components, troubleshooting, and safe working practices, preparing students for further study or employment in ICT.
Topic Overview
The City & Guilds Level 2 Award in ICT Systems and Principles introduces the core components of computer systems, including hardware, software, and the interaction between them. You will learn about the function of key internal components such as the CPU, memory, storage devices, and input/output peripherals, as well as how they work together to execute instructions. This foundation is essential for anyone pursuing a career in IT support, technical sales, or further study in computer science.
The qualification also covers essential networking concepts, including types of networks (LAN, WAN), network devices (switch, router), and the basics of IP addressing. Additionally, you will explore security principles such as malware, firewalls, and safe browsing practices, which are critical in today's digital world. Understanding these topics not only helps you pass the exam but also equips you with practical skills for troubleshooting common IT issues.
Finally, the course emphasises safe working practices, including electrostatic discharge (ESD) precautions and proper handling of hardware. This ensures you can work on computer systems without causing damage to components or risking personal injury. By the end of the award, you will have a solid grasp of how computers operate, how to maintain them, and how to keep data secure—skills that are highly valued by employers.
Key Concepts
Core ideas you must understand for this topic
- →Hardware vs. Software: Hardware is physical components (CPU, RAM, hard drive); software is programs and instructions (operating system, applications).
- →The CPU (Central Processing Unit) executes instructions using the fetch-decode-execute cycle and is often called the 'brain' of the computer.
- →Memory hierarchy: Registers, cache, RAM, and secondary storage—each with different speeds and capacities.
- →Networking fundamentals: LAN vs. WAN, IP addresses, and the roles of switches and routers.
- →Security basics: Malware types (viruses, worms, Trojans), firewalls, and the importance of strong passwords.
Learning Objectives
What you need to know and understand
- Prepare, carry out and document the installation of software, be able to configure installed software, be able to test and install software and resolve problems, be able to operate installed software, Uninstall standard application software
Assessment Criteria
Key criteria assessors look for in your portfolio
- Prepares for installation by checking system requirements.
- Installs software correctly following procedures.
- Configures software to meet user or organisational needs.
- Tests software and resolves installation issues.
- Uninstalls software cleanly without leaving residual files.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always create a system restore point before installing.
- 💡Use silent installation switches for batch deployments.
- 💡Test software in a sandbox environment first.
- 💡Use correct terminology: In mark schemes, terms like 'volatile', 'non-volatile', 'fetch-execute cycle', and 'MAC address' are expected. Avoid vague phrases like 'memory thing'.
- 💡For 6-mark questions, structure your answer with clear paragraphs or bullet points. State the point, explain it, and give an example if possible. This matches the 'describe' or 'explain' command words.
- 💡Always read the question carefully: if it asks for 'two differences', give exactly two, not one or three. Over-answering can waste time and may not gain extra marks.
Common Mistakes
Common errors to avoid in your coursework
- Skipping prerequisite checks before installation.
- Not documenting configuration changes.
- Forcing uninstallation without using proper tools.
- Misconception: More RAM always makes a computer faster. Correction: While more RAM helps if you are running out, adding RAM beyond what is needed does not improve performance; the CPU and storage also matter.
- Misconception: The internet and the World Wide Web are the same. Correction: The internet is the global network of interconnected computers, while the WWW is a service that uses the internet to access web pages.
- Misconception: A firewall is a physical device only. Correction: Firewalls can be hardware or software; they filter incoming and outgoing network traffic based on security rules.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on hardware components. Create flashcards for each component (CPU, RAM, ROM, hard drive, SSD, motherboard) and their functions. Watch videos of disassembly to visualise parts.
- 2Week 2: Study networking and security. Draw diagrams of a LAN and label devices. Practice explaining the difference between a switch and a router. Review common malware types and how to prevent them.
- 3Week 3: Practice past exam questions. Time yourself and mark using the mark scheme. Identify weak areas and revisit those topics.
- 4Week 4: Revise all topics using active recall. Use the prompts in this guide and teach a friend or family member. Take a full mock exam under timed conditions.
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions: These test recall of definitions and facts. Read each option carefully and eliminate obviously wrong answers.
- 📋Short-answer questions (1-2 marks): Often ask for a definition or a list. Give precise, concise answers using correct terminology.
- 📋Extended response questions (6 marks): These require explanation or evaluation. Plan your answer with an introduction, several points, and a conclusion. Use examples to support your points.
- 📋Practical scenario questions: You may be given a problem (e.g., computer won't start) and asked to suggest troubleshooting steps. Think logically and consider hardware and software causes.
Command Word Expectations (CITY & GUILDS LIMITED)
What examiners look for when using specific command words in this specification
Give a detailed account of the features or characteristics of something. For example, 'Describe the function of the CPU' requires you to explain what it does, not just name it.
Give reasons or causes for something. You must show understanding of why or how. For example, 'Explain why RAM is volatile' requires you to state that it loses data when power is off and why that is useful.
Give a brief, factual answer without explanation. For example, 'State one function of a router' – just name it, no detail needed.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A computer has 8 GB of RAM and a 1 TB hard drive. Explain the difference between these two types of memory and state which one is used to store the operating system permanently.
- 1.Step 1: Identify the two types of memory: RAM (main memory) and hard drive (secondary storage).
- 2.Step 2: Describe RAM as volatile, fast, and used for temporary storage of running programs and data.
- 3.Step 3: Describe the hard drive as non-volatile, slower, and used for permanent storage of files and the operating system.
- 4.Step 4: Conclude that the operating system is stored on the hard drive because it needs to be retained when the computer is off.
Question: A user reports that their computer is running slowly. List three possible hardware upgrades that could improve performance and explain why each helps.
- 1.Step 1: Identify common performance bottlenecks: RAM, CPU, and storage drive.
- 2.Step 2: Adding more RAM allows more programs to run simultaneously without using slower virtual memory.
- 3.Step 3: Upgrading to a faster CPU (e.g., higher clock speed or more cores) processes instructions quicker.
- 4.Step 4: Replacing a hard drive with an SSD (Solid State Drive) speeds up data access and boot times.
- 5.Step 5: Summarise that these upgrades reduce bottlenecks and improve overall system responsiveness.
