ICTSAS218 Obtain and connect hardware peripherals

A peripheral is a device that attaches to and is used with a computer but is not part of its core architecture of processor and memory. Peripherals fall into three groups:

• Input devices send data and control signals in: keyboard, mouse, trackpad, touchscreen, stylus and drawing tablet, scanner, webcam and camera, microphone, game controller, barcode reader, fingerprint reader.
• Output devices present information out in a form people (or other machines) can use: monitor, projector, printer, 3D printer, speakers and headphones.
• Storage devices hold data: external SSDs and hard drives, USB flash drives, memory cards, network storage.

Some devices are both input and output: a touchscreen, a headset with a microphone, a multifunction printer that scans and prints.

Think beyond the desk. A car key fob is a tiny computer: its buttons (lock, unlock, boot release) are input devices, a small processor runs a program stored in its memory, a battery powers it, and its output is a radio or infrared signal to the car. The same input, process, output model describes everything from a smartwatch to a point-of-sale terminal.

Choosing peripherals is a business decision as much as a technical one.

Quality. Price and quality are related, but not reliably. Quality shows up in build and component quality, the user interface, technical specifications, independent benchmark and review results, the warranty, customer service and the vendor's reputation. The same item can vary widely in price between vendors, so compare.

Fit for purpose and future-proofing. Will it meet the need, not only now but for its expected working life, typically three to five years for business equipment? A slightly higher specification now can avoid replacement mid-life.

Volume. Larger organisations buy through procurement policies, which usually cover volume discounts and preferred suppliers. Buying a few spares with a large order means a failed unit can be swapped immediately.

Compatibility. Check the peripheral's connectors, drivers and supported operating systems against the organisation's hardware blueprint (its standard hardware list) and standard operating environment.

Warranty and support. Does the warranty cover the expected life? If not, is extended warranty worth buying, or is the item cheap enough to replace? What support is offered: a 24/7 phone line, an account manager, a service level agreement, on-site repair? Warranties come in different forms:

• Return to base (RTB): the faulty item is sent back to the manufacturer or the vendor's service centre for repair or replacement, and you usually pay to send it. You are without the item until it comes back.
• On-site or next business day: a technician comes to you or a replacement is sent. Common for business laptops and servers, at a higher price. Response times in remote parts of the NT can be longer than advertised, so check what "on-site" means for Alice Springs or a community.
• Advance replacement: the vendor sends a replacement before you return the faulty unit.

Understanding the warranty before buying tells you how long a user will be without the device if it fails, and who pays.

In Australia, the Australian Consumer Law also gives automatic consumer guarantees: goods must be of acceptable quality, fit for any disclosed purpose, and match their description. These apply regardless of the manufacturer's warranty, and a business cannot sign them away for purchases that fall within the law's thresholds.

Vendor reputation and legitimacy. For a large purchase, due diligence matters: what happens if the vendor goes out of business during the warranty? For online purchases, check that a vendor is genuine before paying:

• Look up its Australian Business Number on the ABN Lookup site (abr.business.gov.au), and check the business name and location match.
• Read independent reviews on third-party sites, not only testimonials on the vendor's own site.
• Be suspicious of prices far below every other seller, websites registered very recently, pressure to pay by bank transfer, gift card or cryptocurrency, and no physical address or phone number.
• Ask other businesses and colleagues about their experience.
• Check Scamwatch (scamwatch.gov.au) for current fake-store scams.

Specifying a whole system brings these ideas together. Consider a typical brief: a retired client in her seventies in Moil, Darwin, wants a new desktop computer with keyboard, mouse and monitor to replace a ten-year-old machine. She mainly makes video calls to family, emails and browses the web. She already has a recent USB printer. The budget is $1,200 including delivery, installation, data transfer from the old machine and removal of the old system.

A sensible recommendation would be a modest current machine, either a compact desktop or an all-in-one:

• A current entry-level processor (Intel Core i3 or Core 5, or AMD Ryzen 3 or 5), which is ample for video calls and browsing.
• 8 GB of RAM at minimum, 16 GB if the budget allows, for a longer useful life.
• A 256 GB to 512 GB SSD, for fast start-up.
• Windows 11 (or, if she already uses an iPad or iPhone, a case could be made for a Mac mini or an iMac, if the budget stretches).
• A webcam and microphone, since video calling is the main use. An all-in-one includes them; for a desktop, a separate 1080p webcam.
• A 24-inch monitor with a comfortable, adjustable stand, and possibly a larger-text keyboard.
• Video calling software she can use easily. Older course material names Skype, but Microsoft retired Skype in May 2025 and moved users to Microsoft Teams; WhatsApp, FaceTime (Apple devices) and Zoom are the common alternatives, and the best choice is whatever her family already uses.

A good recommendation letter explains why each part was chosen in plain language, states the total cost and the warranty, sets out an implementation schedule, and includes a place for the client to sign acceptance. The schedule would cover ordering (allow for freight times to Darwin, which can be days longer than to the east coast), building and testing, a secure data transfer, delivery and set-up, removal and responsible disposal of the old machine, and a follow-up.

The data transfer and the old machine deserve particular care. Copy her documents, photos, email and browser bookmarks to the new machine (with an external drive or a migration tool), verify with her that everything is there, and keep the backup until she is satisfied. Then erase the old drive properly before it leaves her hands (see disposal, below). Explain what was done so she can be confident her data is safe.

Checking satisfaction afterwards closes the job: confirm verbally when set-up is done, follow up by phone or email a week later, or use a short survey.

Hardware inventory registers

A hardware inventory (or asset register) is a list of every piece of hardware an organisation owns or uses: computers, laptops, phones, monitors, printers, projectors, network equipment, cameras. Even a 20 to 30 person organisation quickly loses track without one. It supports budgeting and replacement planning, warranty claims, insurance, security (knowing what is on the network, and what is missing), software licensing and audits.

A register typically records, for each item:

• asset number (the organisation's own tag) and serial number;
• make, model and equipment type;
• location (building, room, cupboard) or assigned user;
• purchase date, supplier and cost;
• warranty type and expiry;
• current firmware, operating system or software version, and a link to the vendor's support page;
• condition and notes (for example "needs new ink cartridges").

Keeping it current is the hard part. Update it whenever equipment arrives, moves, changes hands, is repaired or is disposed of. Larger organisations use IT asset management software, often with agents that report automatically what each computer is and what is installed, and barcode or QR asset tags scanned with a phone.

Packing lists

A packing list is the document that travels with a delivery listing what is in the package: item descriptions, quantities, part numbers and sometimes weights, but not prices (the invoice has those). It lets carriers, customs and the receiver know what should be there.

When goods arrive:

• Check the outside of the package for damage before signing for it, and note any damage on the delivery record.
• Open it and check every item against the packing list and against the original order.
• Check each item is the right model and appears serviceable: no damage, all accessories, cables and manuals present, seals intact.
• If anything is missing, wrong or faulty, photograph the contents and packaging and contact the supplier straight away, quoting the order number. Suppliers typically send the missing part, replace the item, or offer a credit; most require prompt notice.
• Record the items in the inventory register.

Storing hardware

Store peripherals and spare components as the manufacturer's documentation specifies (usually in the user manual or on the support site): in original packaging or antistatic bags, in a cool, dry place out of direct sunlight, away from dust, with batteries removed for long-term storage and lithium batteries kept partly charged, labelled, and recorded in the register with their location. Heat and humidity in the Top End, and fine dust in Central Australia, both shorten equipment life, so storage conditions matter more here than in milder climates.

Knowing ports on sight is a core skill for this unit.

USB

USB is now the universal connector for peripherals, but its naming has been confusing. It helps to separate the connector shape from the data speed.

Connector shapes:

Connector	Description	Status
USB-A	The familiar flat rectangle; only fits one way	Still very common on computers and chargers
USB-B	Square with bevelled top; used on printers and some hubs	Legacy, still seen on printers
Mini-USB	Small trapezoid; older cameras and phones	Obsolete
Micro-USB	Thin trapezoid; older Android phones and small devices	Legacy, being replaced
USB-C	Small oval, reversible (fits either way up)	Current standard for data, charging and video

Data speeds, with the USB-IF's current simplified names:

Generation	Speed	Current name
USB 1.1	12 Mbps	(legacy)
USB 2.0 (2000)	480 Mbps	Hi-Speed USB
USB 3.0, later 3.1 Gen 1 and 3.2 Gen 1	5 Gbps	USB 5Gbps
USB 3.1 Gen 2, later 3.2 Gen 2	10 Gbps	USB 10Gbps
USB 3.2 Gen 2x2	20 Gbps	USB 20Gbps
USB4 (2019)	40 Gbps	USB 40Gbps
USB4 Version 2.0 (2022)	80 Gbps (up to 120 Gbps one way)	USB 80Gbps

The important point is that a USB-C port can run at any of these speeds, or only USB 2.0, so the shape tells you nothing about speed. Check the logo or the specification. USB 3 ports on USB-A are often blue.

USB also carries power. Plain USB 2.0 supplies 2.5 W; USB Power Delivery over USB-C now goes up to 240 W with a suitable cable (Extended Power Range, from 2021), enough to charge most laptops and power monitors. Apple replaced its Lightning connector with USB-C on the iPhone 15 in 2023, and the European Union's common charger rules have pushed the whole industry to USB-C.

Thunderbolt, from Intel and Apple, uses the USB-C connector and is compatible with USB4. Thunderbolt 4 runs at 40 Gbps; Thunderbolt 5 (announced 2023) runs at 80 Gbps, with a boost mode up to 120 Gbps for displays. It is common on docks for laptops, driving several monitors, network and storage through one cable.

Display connectors

Connector	Signal	Notes
VGA	Analogue video only	Blue 15-pin D connector. Obsolete but still on older projectors
DVI	Digital (DVI-D) or both (DVI-I) video	Largely replaced by HDMI and DisplayPort
HDMI	Digital video and audio in one cable	Standard on TVs, projectors and monitors. HDMI 2.0 carries 18 Gbps (4K at 60 Hz); HDMI 2.1 carries 48 Gbps (4K at 120 Hz, 8K); HDMI 2.2, released June 2025, carries 96 Gbps with new Ultra96 cables. Mini and Micro HDMI are smaller sockets for cameras and small devices
DisplayPort	Digital video and audio	Common on PC monitors and graphics cards; supports daisy-chaining monitors. DisplayPort 2.1 reaches 80 Gbps
USB-C (DisplayPort Alt Mode, Thunderbolt)	Video, data and power together	Increasingly the only video output on laptops

HDMI's big advance over DVI and VGA was carrying high-quality video and audio in one cable. Bandwidth matters because higher resolutions and refresh rates need more of it; this is why a 4K monitor may only run at 30 Hz on an old HDMI 1.4 port.

Other connectors

• RJ45 Ethernet, for wired networking. Standard office ports run at 1 Gbps; 2.5 Gbps is now common on new motherboards; data centres run far faster.
• 3.5 mm audio jacks: three-contact (TRS) for stereo headphones or a microphone; four-contact (TRRS) for headsets combining headphones and microphone. Many phones and some laptops have dropped them in favour of USB-C and Bluetooth audio.
• Legacy connectors you may still meet on old equipment: PS/2 (round, purple for keyboard, green for mouse), serial (9-pin) and parallel (25-pin) ports, FireWire (IEEE 1394, Apple and Sony's former high-speed port for cameras and audio), and SCSI (an old family of standards for connecting drives and scanners, which survives in servers as SAS).

A personal area network (PAN) links devices within a few metres of one person. Wireless keyboards, mice, headphones and game controllers are now normal and cheap.

Bluetooth is the dominant PAN technology, operating at 2.4 GHz. Bluetooth devices come in power classes:

Class	Maximum power	Typical range
Class 1	100 mW	Up to about 100 m
Class 2	2.5 mW	About 10 m
Class 3	1 mW	About 1 m

Most phones and peripherals are Class 2. Bluetooth Low Energy (LE) serves low-power devices like fitness bands and sensors. LE Audio (from 2022) and its Auracast broadcast feature let one device stream audio to many headphones or hearing aids. Bluetooth 6.0 (September 2024) added channel sounding for precise distance measurement, which helps with features such as digital car keys and item trackers.

To pair a Bluetooth device in Windows 11: put the device in pairing mode (usually by holding its power or pairing button until a light flashes), then Settings, Bluetooth & devices, Add device, Bluetooth, select the device, and confirm any code shown.

Some wireless keyboards and mice use a small USB receiver (dongle) instead of Bluetooth; plug it in and the device works without pairing.

Infrared (IR) uses invisible light just beyond red in the spectrum. It needs line of sight, cannot pass through walls, and works only over short distances, which is why TV remote controls use it.

NFC (near-field communication) works over a few centimetres; it is used for tap-to-pay, pairing headphones by touching them to a phone, and access cards.

Zigbee, Z-Wave and Thread are low-power, low-data-rate standards for smart-home sensors, locks and lights, built to run for years on small batteries. Zigbee and Thread are based on the IEEE 802.15.4 standard. The Matter standard, launched in 2022, runs over Thread and Wi-Fi and aims to make smart-home devices from different brands work together.

Before the mid-1990s, adding hardware to a PC often meant setting jumpers and manually resolving resource conflicts. Windows 95 introduced plug and play: the operating system detects new hardware and configures it automatically, and most current interfaces (USB, PCI Express, SATA, Thunderbolt, HDMI and DisplayPort) are designed for it.

Plug and play gets a device working; the manufacturer's driver often unlocks its full features. Windows 11 installs a basic driver automatically for most peripherals, and often fetches the manufacturer's driver through Windows Update. For printers, scanners, drawing tablets, gaming mice and audio interfaces, install the manufacturer's driver or software from its support site for full functionality.

Updating drivers

Know all the ways, because each has its place:

• Check what is installed. Open Device Manager (right-click Start, Device Manager). Expand the categories that matter: Display adapters, Network adapters, Sound, video and game controllers, and System devices (where chipset components appear). A yellow triangle means a driver problem; a generic name (such as "Microsoft Basic Display Adapter") means the proper driver is not installed.
• Windows Update. Settings, Windows Update, Check for updates; then Advanced options, Optional updates, Driver updates, and install any listed. This is the safest method for general hardware.
• Device Manager. Right-click the device, Update driver, then Search automatically for drivers, or Browse my computer for drivers if you have downloaded one.
• The manufacturer's website. Identify the exact model of the PC or motherboard and the Windows version, go to the maker's Support, Drivers and Downloads page (Dell, HP, Lenovo, ASUS, MSI, Acer, or the chip makers Intel, AMD, NVIDIA), download the right drivers, and run the installers.
• Chipset drivers. These control communication between the CPU, memory, storage and the motherboard, and should be installed first on a fresh system. Identify the chipset (Device Manager, System devices; or msinfo32; or the motherboard's documentation), download the package from Intel (Chipset Device Software) or AMD (AMD Chipset Drivers), install it, and restart.
• Verify. Back in Device Manager, open the device's Properties, Driver tab, and check the provider, date and version. Confirm no warning icons remain.

Good practice: download drivers only from official sources; create a restore point before major driver updates; restart after installing; and avoid third-party "driver updater" tools, which are a common source of unwanted software. If a new driver causes trouble, use Roll Back Driver on the Driver tab.

Connecting, configuring and testing a peripheral

The same pattern works for any peripheral:

• Read the quick start guide. Some devices (particularly printers and audio interfaces) want their software installed before they are plugged in.
• Connect it using the recommended port and cable, and power it on.
• Let Windows detect it, then install the manufacturer's driver or software if needed.
• Configure it: set the default printer, the display resolution and arrangement for a second monitor (Settings, System, Display), the default audio device (Settings, System, Sound), pen pressure and buttons for a drawing tablet.
• Test it against the vendor's specification: print a test page; check the monitor runs at its native resolution and refresh rate; record and play back audio; check a scanner scans at the expected resolution.
• If it does not work as specified, check the obvious (power, cable, port, driver), consult the manufacturer's troubleshooting guide, and if it remains unresolved, report it to your supervisor or the help desk, recording what device, what fault, what you tried and when. Faults under warranty then go to the vendor.

This unit expects you to take a computer apart and put it back together, to remove old ("expired") components without damaging the rest of the system, and to identify what you find.

Before you start

• Make sure the computer works before you touch it, so you know any later fault is new.
• Back up data if the machine is in use.
• Shut down, switch off at the wall, and unplug the power cable. Press the power button once after unplugging to drain residual charge.
• Clear the workspace, and have a container or magnetic tray for screws.
• Use antistatic precautions (below).
• Start a job card: a record of every part removed, where it was located, and how it was connected (cable type, slot, screws), with photos taken on a phone at each stage. The job card is your reassembly guide.

Electrostatic discharge

Electrostatic discharge (ESD) is the sudden flow of static electricity when two objects at different electrical potentials touch. Your body builds up static charge as you move, particularly on carpet and synthetic clothing. A discharge you cannot even feel can damage or weaken sensitive electronic components, sometimes causing faults that only show up later.

Protect against it by:

• wearing an antistatic wrist strap clipped to bare metal on the computer's chassis, or working on an ESD mat;
• touching bare metal on the case before handling components, to equalise your charge with it;
• keeping components in antistatic bags until needed, handling them by the edges, and not touching gold contacts or chips;
• avoiding working on carpet.

ESD risk rises when the air is dry. Darwin's humid wet season reduces it, but Alice Springs is one of the driest places in Australia, and air-conditioned rooms anywhere are dry, so antistatic precautions are essential there.

Identifying components

When the side panel is off, you should be able to identify:

• Motherboard, the main board everything connects to.
• CPU and its heatsink and fan (the heatsink sits on top of the processor with thermal paste between them; clean off and replace the paste if the heatsink is removed).
• RAM modules in the DIMM slots, released by clips at the ends of the slot.
• Storage: 2.5 or 3.5 inch drives with SATA data and power cables, or M.2 SSDs on the board, held by one small screw.
• Power supply unit, with its bundle of cables to the motherboard (24-pin), CPU (4 or 8-pin), graphics card and drives. Never open the PSU itself.
• Expansion slots, especially the PCIe x16 slot for a graphics card, and any cards fitted (graphics, wireless, network).
• The CMOS battery, a coin cell (usually CR2032) that keeps the firmware clock and settings.
• The chipset. On older motherboards there are two support chips, often under small heatsinks: the northbridge (near the CPU, linking it to memory and graphics) and the southbridge (handling slower input and output). From around 2008 to 2011 the northbridge's functions moved inside the processor, and current motherboards have a single chipset chip (Intel's Platform Controller Hub, or an AMD chipset). You will see a northbridge on an older lab PC but not on a new one.
• Front panel connectors (power switch, reset, LEDs, front USB and audio), the small, fiddly headers that are the most common cause of "it won't turn on" after reassembly. Photograph them before disconnecting.
• External items: keyboard, mouse, monitor, USB network adapter, and any other peripherals.

Reassembly and first boot

Reassemble in reverse order using the job card and photos, checking every cable is fully seated. Before closing the case, connect power, monitor and keyboard and test that it boots (the POST completes and the firmware or operating system appears). Common reasons for failure: RAM not fully clipped in, the CPU power cable or 24-pin cable not connected, front panel connectors on the wrong pins, or the graphics output cable plugged into the motherboard when a graphics card is fitted.

After a rebuild, the operating system is installed and the machine brought into service. (Installing Windows is covered in ICTICT213.) The configuration tasks a support technician should be able to do, with Windows 11 paths:

• Connect to the internet: plug in Ethernet, or choose a Wi-Fi network from the network icon on the taskbar.
• Set the time zone: Settings, Time & language, Date & time; turn off automatic time zone, choose (UTC+09:30) Darwin.
• Change the desktop background colour: Settings, Personalisation, Background, Solid colour.
• Create a local user account: Settings, Accounts, Other users, Add account, then "I don't have this person's sign-in information", then "Add a user without a Microsoft account", and enter the name and password. From an administrator prompt: net user alex StrongPassphrase1 /add.
• Make a user an administrator: Settings, Accounts, Other users, select the user, Change account type, Administrator. From the prompt: net localgroup administrators alex /add. In workplaces, day-to-day accounts should be standard users, and administrator rights kept to separate accounts used only when needed; restricting administrative privileges is one of the Essential Eight.
• Create a system restore point: search Start for "Create a restore point", System Protection tab, turn on protection for the system drive if needed, then Create.
• Change power settings: Settings, System, Power (Power & battery on a laptop), for screen and sleep timeouts and power mode.
• Open Task Manager: Ctrl + Shift + Esc, or right-click Start, Task Manager.
• Uninstall an application: Settings, Apps, Installed apps, the three-dot menu, Uninstall.
• Command line checks: ping cdu.edu.au to test a connection to a domain; ipconfig to find the local IPv4 address assigned by DHCP (and ipconfig /all to see the DHCP server and lease).

An IT workshop has its own hazards:

• Electrical: unplug before opening equipment; never open power supplies or monitors (both hold dangerous charge); check leads for damage; follow the organisation's test-and-tag regime for portable electrical equipment (AS/NZS 3760).
• Manual handling: lift correctly, get help with servers, large monitors and printers, and use trolleys.
• Sharp edges inside cases and on metal brackets; wear gloves where appropriate.
• Trip hazards from cables; slip hazards from spills (no drinks at the bench).
• Lithium batteries: damaged, swollen or overheated batteries can catch fire; isolate them and follow the organisation's procedure.
• Chemicals: isopropyl alcohol, thermal paste and compressed air (never shake or invert the can; use in ventilated areas).
• Lighting and ergonomics at the bench: good light and a bench at a comfortable height.
• Heat stress in hot workshops, a real issue in the NT.

Workers must follow reasonable WHS instructions and report hazards and incidents through the organisation's procedure.

E-waste, discarded electrical and electronic equipment, is one of the fastest-growing waste streams in the world, and it contains lead, mercury, cadmium and brominated flame retardants that contaminate soil and water if landfilled. It also contains valuable recoverable metals, including gold, copper and rare earths.

Responsible disposal in Australia:

• The National Television and Computer Recycling Scheme provides free drop-off of computers, printers, peripherals and televisions at participating sites. Planet Ark's Recycling Near You (recyclingnearyou.com.au) lists them. In Darwin, e-waste can also go to the Shoal Bay transfer station, and working equipment to its reuse shop.
• Batteries never go in the bin. Lithium batteries start fires in bins, collection trucks and waste facilities, and other batteries leak heavy metals in landfill. Take them to a drop-off point; B-cycle, the national battery stewardship scheme, lists locations (bcycle.com.au).
• Equipment in working order can be donated or refurbished; old phones and tablets find second lives as calendars, music players or baby monitors.
• Businesses often use a certified IT asset disposal (ITAD) provider, which securely destroys data and provides certificates of destruction and recycling, supporting privacy and environmental compliance.

Data security comes first. Before any storage leaves the organisation or the client's home, data must be removed properly: deleting files or formatting a drive does not erase the data. Use the drive manufacturer's secure erase tool or a verified wiping tool, or physically destroy the drive, following recognised guidance such as the Australian Government's Information Security Manual or NIST's media sanitisation guidelines, and record what was done. For SSDs, the manufacturer's secure erase or cryptographic erase is the reliable method, because wiping tools designed for hard drives do not reach every cell.

This unit places hardware work inside a support process. Requests arrive through a help desk or ticketing system (ServiceNow, Jira Service Management, Freshdesk and similar), which records the request, who owns it, its priority and its history. Good practice: log everything; confirm the work brief before starting; keep the user informed; record what was done, what was replaced and what the result was; update the inventory register; and close the ticket only when the user confirms the problem is solved. If something is beyond your authority or skill, escalate it with clear notes rather than guessing. Planned maintenance (firmware updates, cleaning, battery checks, replacing ageing equipment) is scheduled in advance and communicated to users.

AI is changing the hardware itself. New "AI PCs" include a neural processing unit (NPU) for on-device AI, and Microsoft's Copilot+ PCs need an NPU rated at 40 or more TOPS and at least 16 GB of RAM for some Windows AI features, so client requirements now need to be checked against those specifications. Webcams and headsets increasingly use AI for background blur, framing and noise removal, sometimes in the device, sometimes in the PC's NPU. And new keyboards carry a dedicated Copilot key.

AI also helps with the research side of this unit: comparing specifications, summarising a vendor's warranty terms, or drafting a recommendation letter. The same checks apply as for any source. Confirm specifications and prices on the vendor's own site, and never enter a client's personal information into an AI tool the organisation has not approved.

The unit's teaching content is drawn from the CDU material held in the unit folder: the ICTSAS218 learning resource page on the CDU student site (last updated 22 May 2026), the ICTSAS218 Assessor Guide v4.4 (undated), the ICTSAS218 Student Unit Guide, the assessor instructions for the practical demonstration and for driver updates (undated), the job card template, the ICTSAS218 validation report, and the ICT20120 practical observation checklist (February 2026). The unit is current at training.gov.au (no page date shown). Current-practice material was checked on 20 September 2026 against: the HDMI Forum's release of HDMI 2.2 (25 June 2025); Intel's Thunderbolt 5 announcement (2023) and USB-IF's USB4 Version 2.0 specification and USB naming (2022); the Bluetooth SIG's Bluetooth Core 6.0 overview (September 2024); Microsoft Learn, Windows 11 requirements (updated 14 July 2026); the City of Darwin e-waste page (no date shown); Planet Ark's Recycling Near You and the National Television and Computer Recycling Scheme pages (no date shown); and B-cycle (no date shown). Skype's retirement in May 2025, the Australian Consumer Law consumer guarantees, the ABN Lookup and Scamwatch services, the history of the northbridge, and USB Power Delivery's 240 W extended power range reflect widely documented information from the relevant organisations rather than a single dated source.
