Assessment criteria
Topic Overview
The City & Guilds Level 2 Diploma in ICT Systems Support is a vocational qualification designed to equip students with the practical skills and knowledge needed to provide effective technical support in a range of ICT environments. This diploma covers essential areas such as computer hardware, software installation, networking fundamentals, and customer service skills. Students learn how to diagnose and resolve common ICT issues, maintain systems, and communicate effectively with users, making it ideal for those aspiring to roles like IT support technician or helpdesk analyst.
This qualification is structured around real-world scenarios, ensuring that students gain hands-on experience with tasks such as assembling and upgrading computer components, configuring operating systems, setting up networks, and troubleshooting hardware and software problems. It also emphasizes the importance of health and safety, data protection, and professional conduct in the workplace. By completing this diploma, students build a solid foundation for further study in ICT or direct entry into entry-level IT support roles.
In the wider context of computer science, this diploma bridges the gap between theoretical concepts and practical application. While computer science degrees often focus on programming and algorithms, ICT systems support focuses on the maintenance and operation of existing systems. This makes it a valuable complement to more theoretical studies, as it develops problem-solving skills and technical proficiency that are highly sought after by employers. The qualification also aligns with industry standards, such as CompTIA A+ and ITIL, preparing students for professional certifications.
Key Concepts
Core ideas you must understand for this topic
- →Computer hardware components: Understanding the function and installation of CPUs, RAM, hard drives, power supplies, and motherboards, including how they interact to form a working system.
- →Operating system configuration: Installing and configuring Windows or Linux, managing user accounts, file systems, and system settings, as well as performing routine maintenance like disk cleanup and defragmentation.
- →Networking fundamentals: Setting up and troubleshooting local area networks (LANs), including IP addressing, subnetting, DHCP, DNS, and basic router/switch configuration.
- →Customer service and communication: Applying ITIL principles to handle support tickets, manage user expectations, and document solutions clearly and professionally.
- →Health and safety in ICT: Following regulations such as COSHH and Display Screen Equipment (DSE) assessments, and safely handling hardware to prevent electrostatic discharge (ESD) damage.
Learning Objectives
What you need to know and understand
- Understand systems supporting ‘Shells, Scripting and Data management’, Be able to manage user interfaces and desktops, Be able to manage Linux based Administrative Tasks, Be able to manage Linux Essential System Services, Understand networking fundamentals, Be able to manage Linux based security
Assessment Criteria
Key criteria assessors look for in your portfolio
- Writes and executes shell scripts for automation.
- Manages user accounts, permissions, and desktop environments.
- Configures essential system services (e.g., SSH, Apache).
- Implements basic security measures (firewall, user authentication).
Assessment Guidance
Guidance for achieving higher grades
- 💡Practice using man pages to understand command options.
- 💡Test scripts in a safe environment before production.
- 💡Learn common log file locations for troubleshooting.
- 💡When answering questions about troubleshooting, always follow a logical step-by-step process: identify the problem, establish a theory of probable cause, test the theory, implement a solution, verify full system functionality, and document findings. This structured approach earns maximum marks.
- 💡For hardware questions, be specific about components and their roles. Instead of saying 'replace the faulty part,' name the exact component (e.g., 'replace the failed hard drive with a compatible SATA SSD') and explain why it's appropriate.
- 💡In networking questions, always include IP addressing details. For example, when explaining DHCP, mention that it assigns IP addresses dynamically from a defined range, reducing manual configuration errors. Show you understand the practical implications.
Common Mistakes
Common errors to avoid in your coursework
- Forgetting to make scripts executable with chmod.
- Misconfiguring firewall rules locking out access.
- Neglecting to update system packages regularly.
- Misconception: 'If a computer won't turn on, the power supply must be faulty.' Correction: Always check the power cable, socket, and switch first. A faulty power supply is just one possibility; the motherboard, CPU, or RAM could also cause a no-power condition.
- Misconception: 'More RAM always makes a computer faster.' Correction: Adding RAM only improves performance if the system is currently running out of memory. If the system has sufficient RAM for its tasks, adding more will not yield noticeable speed gains.
- Misconception: 'Antivirus software can prevent all malware infections.' Correction: Antivirus is essential but not foolproof. It relies on signature updates and heuristic analysis; new or sophisticated malware can bypass it. Safe browsing habits and regular updates are equally important.
