HSC Information and Digital Technology (VET) study guide
HSC Information and Digital Technology (VET) · Work through your exam, one topic at a time.
The HSC Information and Digital Technology (IDT) VET course is a NSW senior secondary vocational qualification that pairs industry-recognised competencies with a written HSC examination. It suits students who want practical, hands-on ICT skills - building and supporting hardware, working with networks, handling data and digital media, and dealing with clients - alongside a pathway into further study, traineeships or entry-level IT work. The HSC Information and Digital Technology (VET) study guide has 8 sections and about 2,841 words.
01Industry knowledge, workplace practices and the digital technologies industry
The digital technologies industry spans hardware supply and repair, software development, networking, cloud services, technical support and digital media. Candidates should be able to describe the main sectors and the roles inside them, the difference between vendor, reseller, managed service provider and in-house IT, and how work is organised through projects, service level agreements (SLAs) and job tickets.
382 words, about 2 min02Work health and safety, and environmental sustainability
Work health and safety (WHS) in IT is about identifying hazards, assessing risk and applying the hierarchy of control. Typical hazards include manual handling of monitors and servers, electrical risk from power supplies and cabling, trips from loose cables, ergonomic strain from prolonged keyboard and mouse use, eye strain from screens, and psychosocial hazards such as workload and aggressive customers.
390 words, about 2 min03Communication, teamwork and customer service
Technical skill is only half of IT support; the other half is communication. Candidates must understand the communication process (sender, message, channel, receiver, feedback, noise), the difference between verbal and non-verbal cues, and how to adapt language for technical and non-technical audiences.
354 words, about 2 min04Hardware, software and operating systems
This domain covers the components of a computer system and how software and operating systems manage them. Candidates should know the roles of CPU, RAM, storage (HDD, SSD, NVMe), motherboard, PSU, GPU and peripherals, and the input-process-output-storage model.
352 words, about 2 min05Networks, connectivity and security
Networking covers how devices communicate and how that communication is protected. Candidates should understand the OSI and TCP/IP models at a conceptual level, the roles of IP addressing (IPv4 and IPv6), subnet masks, DHCP, DNS, gateways and NAT, and the difference between LAN, WAN, WLAN, VPN and the internet.
337 words, about 2 min06Data, information management and digital media
This domain is about turning raw data into useful information and managing it responsibly. Candidates should understand the data-information-knowledge distinction, data types (text, numeric, dates, images, audio, video), validation and verification, and the difference between them: validation checks whether data is reasonable (range, type, format, presence), while verification checks whether it matches the source (double entry, visual check).
345 words, about 2 min07Problem solving, troubleshooting and technical support
Troubleshooting is a systematic process, not guesswork. Candidates should know a structured methodology: gather information and reproduce the problem, identify recent changes, establish a theory, test it, plan and implement a solution, verify full functionality, and document the outcome.
360 words, about 2 min08Employability skills, career pathways and legal/ethical issues
This domain connects technical work to professional and legal responsibilities. Employability skills include communication, teamwork, problem solving, initiative, planning, self-management, learning and technology use.
