Assessment criteria
Topic Overview
The City & Guilds Level 2 Certificate in ICT Systems Support provides foundational knowledge and practical skills for maintaining and supporting ICT systems in a professional environment. This qualification covers essential topics such as computer hardware, software installation, networking fundamentals, and troubleshooting techniques. Students learn how to identify and resolve common technical issues, configure operating systems, and ensure system security, preparing them for roles like IT support technician or helpdesk analyst.
This qualification is designed for individuals who want to start a career in IT support or progress to more advanced studies. It emphasizes hands-on experience with real-world scenarios, including setting up workstations, managing user accounts, and performing routine maintenance. By the end of the course, students will be able to diagnose hardware and software faults, apply safe working practices, and communicate effectively with end-users to resolve issues efficiently.
In the wider context of computer science, ICT systems support is a critical function that ensures technology runs smoothly in businesses, schools, and other organizations. This qualification bridges the gap between basic computer literacy and specialized technical roles, providing a stepping stone to further certifications such as CompTIA A+ or City & Guilds Level 3 qualifications. It also develops problem-solving and customer service skills that are valuable across many industries.
Key Concepts
Core ideas you must understand for this topic
- →Hardware components: Understanding the function and interaction of CPUs, RAM, storage devices, motherboards, and power supplies, including how to upgrade or replace them.
- →Operating systems: Installing, configuring, and maintaining Windows and Linux OS, managing user accounts, file permissions, and system updates.
- →Networking basics: TCP/IP, IP addressing, subnetting, configuring routers and switches, and troubleshooting connectivity issues using tools like ping and tracert.
- →Troubleshooting methodology: Following a systematic approach (identify, research, implement, verify) to resolve hardware, software, and network problems.
- →Health and safety: Applying electrostatic discharge (ESD) precautions, safe lifting techniques, and proper cable management to prevent accidents and equipment damage.
Learning Objectives
What you need to know and understand
- Be able to identify and understand routing protocols, Configure a router to communicate with a WAN infrastructure, Test and troubleshoot a network system, Implement address management
Assessment Criteria
Key criteria assessors look for in your portfolio
- Identify and explain routing protocols such as RIP and OSPF.
- Configure a router for WAN connectivity using appropriate protocols.
- Test and troubleshoot network connectivity issues.
- Implement address management using DHCP and NAT.
Assessment Guidance
Guidance for achieving higher grades
- 💡Practice router configuration in a simulator.
- 💡Understand the OSI model layers relevant to routing.
- 💡Use show commands to verify configurations.
- 💡Always use the correct terminology (e.g., 'motherboard' not 'mainboard', 'power supply unit' not 'battery') to show your knowledge. Marks are often awarded for precise language.
- 💡When troubleshooting, write down each step you take and why. Examiners look for a logical, methodical approach, not just the final answer.
- 💡For practical tasks, remember to mention safety precautions (like turning off power before opening a case) even if the question doesn't ask. This demonstrates professionalism.
Common Mistakes
Common errors to avoid in your coursework
- Misconfiguring subnet masks leading to routing errors.
- Forgetting to save running configuration to startup.
- Incorrectly applying access control lists.
- Misconception: 'If a computer won't turn on, the power supply is always faulty.' Correction: Check the power cable, outlet, and power switch first. Also, a faulty motherboard or RAM can prevent booting even if the power supply works.
- Misconception: 'More RAM always makes a computer faster.' Correction: Adding RAM helps only if the system is running out of memory. If the CPU or storage is the bottleneck, extra RAM won't improve performance significantly.
- Misconception: 'Antivirus software is enough to keep a system secure.' Correction: Antivirus is just one layer. Regular updates, strong passwords, firewalls, and user education are also essential for security.
