A switch is a smart device that learns the MAC addresses of connected devices and directs data frames/packets only to the specific port of the intended recipient. A hub, on the other hand, broadcasts data to all ports, which increases network traffic and reduces security. A router is used to connect different networks, and a bridge is used to connect two separate network segments.

Unlike optical discs, which use a spinning disc and laser that can easily skip or get damaged by movement, solid-state drives (SSDs) contain no moving parts. This makes SSDs much more durable and reliable when used in a moving vehicle or while travelling. They are also smaller and do not require an external disc drive.

1 mark for identifying that an SSD has no moving parts or is more durable. 0.5 marks for linking this to why it is beneficial while travelling (e.g., won't get damaged by movement/shocks).

A public IP address is assigned by an ISP and is unique across the entire global internet, enabling communication with external servers. A private IP address is assigned by a local router to devices within a LAN and is only unique inside that network, meaning it cannot be directly routed over the internet.

1 mark for identifying that public IPs are globally unique and used on the internet, while private IPs are used inside local networks. 0.5 marks for noting the routing difference (e.g., private IPs cannot route directly on the internet).

Creative Commons is a standard licensing system that enables creators of intellectual property to grant permissions to the public to use their work freely under certain restrictions, such as requiring attribution, preventing commercial use, or forbidding modifications, without losing their copyright.

1 mark for stating that it allows creators to give public permission to use/share their work while retaining copyright. 0.5 marks for mentioning that this usage is subject to specific conditions or rules set by the creator.

The network is a Local Area Network (LAN). LANs are designed to connect devices over a limited geographical distance, such as a single building, home, or campus. Since the school network is confined to its main building, it fits the definition of a LAN rather than a wide-area network.

0.5 marks for correctly identifying LAN. 1 mark for justifying with reference to the small geographical area or single building/site.

When using third-party cloud storage, personal data is uploaded to remote servers. This introduces the risk of unauthorized access. If a hacker guesses a weak password or intercepts the login details, they gain full access to the files. Additionally, the cloud provider's database could be targeted in a cyberattack, leading to a massive data breach.

1 mark for identifying a valid security risk (e.g., unauthorized access, data breach, account compromise, data intercept). 0.5 marks for explaining how the risk occurs or its consequence on the personal files.

Plagiarism is the act of presenting someone else's work, ideas, or words as your own without giving proper credit (acknowledgement). This is primarily an academic or ethical issue. Copyright infringement, however, is a legal violation where protected creative works are reproduced, distributed, or adapted without the copyright holder's explicit permission, regardless of whether credit is given.

1 mark for defining plagiarism (falsely claiming authorship/failing to cite). 0.5 marks for distinguishing copyright infringement (unauthorised use of copyrighted materials/legal violation).

In a LAN, devices are connected together, allowing resources to be shared. Sharing peripherals like high-quality printers means the office does not need to buy a printer for every single employee, saving money and physical office space.

Award 1 mark for identifying a benefit and 1 mark for a developed explanation of that benefit. Possible answers: Resource sharing (1 mark) such as printers or internet connections, which reduces hardware costs (1 mark). Centralized storage (1 mark) allowing staff to collaborate on files from any workstation (1 mark). Centralized backup (1 mark) ensuring important work is not lost if a local machine fails (1 mark).

Laptops are portable devices and are frequently moved, which increases the risk of being dropped or bumped. Because SSDs use flash memory and have no moving parts, they are highly durable and less likely to suffer physical damage or data loss compared to magnetic HDDs, which rely on delicate read/write heads and spinning platters.

Award 1 mark for identifying a characteristic of SSDs and 1 mark for explaining why this makes it suitable for a laptop. Possible answers: No moving parts / highly durable (1 mark) which prevents physical damage to data when the laptop is moved or dropped (1 mark). Lower power consumption (1 mark) which extends the laptop battery life (1 mark). Faster read/write speeds (1 mark) which allows the operating system and applications to boot up quickly on a portable device (1 mark).

Creative Commons licences allow creators to select specific conditions under which their work can be legally shared. For example, by selecting the 'No Derivatives' or 'Non-Commercial' condition, they can ensure that others cannot modify their work or use it for commercial gain, whilst still allowing free public distribution.

Award 1 mark for identifying a mechanism/condition of Creative Commons and 1 mark for explaining how it protects the work. Possible answers: Setting an Attribution (BY) clause (1 mark) ensuring they always get credit for their work even when shared (1 mark). Setting a Non-Commercial (NC) clause (1 mark) which prevents others from making money from their creative content without a separate agreement (1 mark). Setting a No-Derivatives (ND) clause (1 mark) which prevents others from altering their original design or artwork (1 mark).

Wi-Fi transmits data packets using radio waves, which propagate through walls and open spaces. This means unauthorized individuals located nearby can intercept the transmission data if the network is not properly secured. In contrast, wired networks require a physical connection to a port, meaning data cannot be easily intercepted from outside the building.

Award 1 mark for identifying the transmission medium difference and 1 mark for explaining the security implication. Possible answers: Radio waves are broadcast through the air (1 mark) which means they can be intercepted by unauthorized devices within range of the signal (1 mark). Wired connections require physical access to cables (1 mark) making it much harder for someone outside the premises to connect or intercept data packets (1 mark).

Random Access Memory (RAM) is volatile primary memory. It temporarily stores data and instructions currently in use by the central processing unit (CPU). This allows fast read and write access. Once the computer is powered off, the data in RAM is lost.

Award 1 mark for identifying the correct statement. B: It is a high-speed, volatile memory that temporarily stores data and instructions currently being used by the CPU. Reject all other options.

A Solid State Drive (SSD) uses flash memory to store data. Because it has no moving parts, it can read and write data significantly faster than a traditional Hard Disk Drive (HDD) which relies on spinning magnetic platters and a physical read/write head.

Award 1 mark for identifying the correct storage type and justification. C: A Solid State Drive (SSD) because it uses flash memory which provides faster read/write access times with no moving parts. Reject all other options.

Award 1 mark for identifying the task carried out by utility software. B: Formatting a hard disk drive to prepare it for use. Reject all other options.

A firewall acts as a barrier between an internal network and external networks (such as the Internet). It monitors and filters incoming and outgoing network traffic based on predefined security rules to prevent unauthorized access.

Award 1 mark for identifying the correct purpose of a firewall. B: To monitor and control incoming and outgoing network traffic based on predetermined security rules. Reject all other options.

Device drivers act as a translator interface between the computer's operating system and physical hardware peripherals, converting generic OS commands into instructions that the specific hardware device can understand and execute.

Award 1 mark for stating that it enables communication or translation between the OS and the hardware device. Award 0.5 marks for explaining that this allows the operating system to recognize or use the peripheral correctly.

RAM holds data and programs currently in active use by the CPU. When physical RAM is insufficient, the operating system must use slower virtual memory on the secondary storage device. More RAM prevents this bottleneck, ensuring faster multi-tasking and improved system responsiveness.

Award 1 mark for identifying that more RAM allows more programs/data to be open at once or reduces reliance on virtual memory. Award 0.5 marks for linking this directly to faster data retrieval speeds or prevention of system lag.

Unlike magnetic hard drives, which use physical read/write heads and spinning platters, SSDs use flash memory and contain no moving parts. This makes them highly durable and far less likely to suffer physical damage or data loss when dropped or shaken during outdoor use.

Award 1 mark for stating that SSDs have no moving parts or are shock-resistant. Award 0.5 marks for linking this to increased durability or reduced risk of physical damage/data loss when dropped or used on the move.

Clock speed, measured in gigahertz (GHz), defines the rate at which the CPU can perform fetch-decode-execute cycles. A higher clock speed directly increases the rate at which instructions are processed, leading to shorter processing times for tasks and applications.

Award 1 mark for stating that higher clock speed allows more instructions or cycles to be processed per second. Award 0.5 marks for stating this leads to faster application execution or task completion.

Biometric authentication relies on unique physical traits (such as fingerprint or iris patterns) which cannot easily be guessed, forgotten, or shared. This is significantly more secure than passwords, which users often write down, forget, or share with unauthorized persons.

Award 1 mark for identifying a valid advantage (e.g., unique to the user, cannot be forgotten, difficult to share or copy). Award 0.5 marks for explaining how this makes it more secure or convenient compared to an alphanumeric password.

Over time, files stored on a magnetic hard drive become fragmented (split into parts and scattered across different sectors). Defragmentation utilities rearrange these scattered sectors so that the parts of each file are stored in continuous, contiguous blocks, minimizing read/write head movement and speeding up file access.

Award 1 mark for stating that it rearranges fragmented or scattered file parts into continuous or contiguous blocks. Award 0.5 marks for explaining that this speeds up file retrieval or reduces read/write head movement. Do not award marks for references to SSD optimization.

RAM is used to temporarily store data, programs, and the operating system currently in use. This allows the CPU to access this data much faster than retrieving it from secondary storage.

1 mark for identifying that RAM stores data, instructions, or programs currently in use. 1 mark for explaining that this allows fast or direct access by the CPU, which improves system performance compared to reading from secondary storage.

The clock speed, measured in Gigahertz (GHz), determines how many fetch-decode-execute cycles the CPU can perform per second. A higher clock speed means the processor can run more instructions every second, resulting in faster execution of programs.

1 mark for identifying that clock speed determines the number of cycles or instructions executed per second. 1 mark for linking a higher clock speed to faster processing of programs or tasks.

An SSD does not contain moving parts, which makes it much more robust and less likely to fail if the laptop is dropped or bumped. Additionally, it consumes less power, extending the laptop's battery life.

1 mark for identifying a key characteristic (e.g., no moving parts, lower power consumption, or faster read-write speeds). 1 mark for explaining how this benefits a portable laptop (e.g., less damage when dropped, longer battery life, or faster boot times on the go).

Utility software is system software designed to help analyze, configure, optimize, or maintain a computer. Examples include disk cleanups, defragmenters, and antivirus software, which keep the system running efficiently and securely.

1 mark for identifying that utility software maintains, optimizes, configures, or secures the system. 1 mark for providing an appropriate example or explaining how a specific utility performs this maintenance.

A device driver is a specialized program that allows the operating system to communicate with a specific hardware device, such as a printer or graphics card. It translates the operating system's generic commands into instructions that the specific hardware can understand.

1 mark for stating that it acts as a translator or interface between the operating system and the hardware. 1 mark for explaining that it enables the operating system to control, recognize, or communicate with the peripheral device.

A firewall acts as a barrier between a trusted internal network and an untrusted external network like the internet. It inspects data packets entering or leaving the system and filters or blocks any traffic that does not meet pre-defined security criteria.

1 mark for stating that it monitors or filters incoming and outgoing network traffic. 1 mark for explaining that it blocks unauthorized access or malicious data packets based on security rules.

Biometric systems use unique physical characteristics, such as fingerprints or iris patterns, to verify identity. These features cannot easily be guessed, written down, shared, or forgotten like a standard text-based password, making unauthorized access much harder to achieve.

1 mark for identifying that biometric features are unique to an individual and cannot be easily shared, lost, or forgotten. 1 mark for explaining how this prevents common password security risks like guessing, shoulder surfing, or keylogging.

Plotters are designed to print large-scale vector graphics. Standard desktop inkjet printers are limited to smaller paper sizes (usually up to A4 or A3) and print in raster format, which can lose quality when scaled up. Plotters use pens to draw continuous, highly accurate lines, making them perfect for technical blueprints.

Award 1 mark for each valid reason up to a maximum of 2 marks. Reasons include: Can print on large paper formats (A1/A0) (1); Uses vector lines/continuous lines which provide high precision/accuracy (1); Does not pixelate when drawing long continuous lines (1). Reject: Just 'prints faster' or 'prints in color' without qualification.

Online collaborative workspaces (like Google Workspace, Microsoft Teams, or Trello) provide features such as real-time co-authoring, which prevents team members from working on outdated versions of files. They also centralize communication and task management, ensuring everyone has immediate access to the latest updates regardless of their physical location.

Award 1 mark for each valid description up to a maximum of 2 marks. Descriptions include: Real-time editing/simultaneous document collaboration (1); Centralized storage/easy access to the latest file versions (reduces version conflicts) (1); Integrated communication/task tracking tools that keep everyone updated instantly (1). Reject: Answers only mentioning 'saves money on travel' (as this is cost, not direct workspace collaboration productivity) unless linked to work efficiency.

Cloud storage offers the advantage of universal access and automatic backups, which protects against local hardware failure. However, it heavily relies on internet connectivity, meaning slow connection speeds will delay the transfer of large files, and subscription fees can accumulate over time.

Award 1 mark for a valid advantage and 1 mark for a valid disadvantage (Max 2 marks). Advantage: Accessible from any location/device with internet (1); Easier to share files with clients via links (1); Automatic backup/protection against local physical damage (fire/theft) (1). Disadvantage: Requires a constant/reliable internet connection (1); Can be slow to upload/download very large files (1); Ongoing subscription costs/fees (1); Security/privacy concerns of storing data on third-party servers (1).

While anti-malware software is crucial, comprehensive security requires other measures. A firewall acts as a barrier to block unauthorized access to the network. Educating users (students and staff) helps prevent social engineering attacks, such as phishing, which are common ways malware enters a network. Other methods include keeping operating systems updated (patching) and restricting user access privileges.

Award 1 mark for each valid measure up to a maximum of 2 marks. Measures include: Set up/configure a firewall (1); Educate/train users to recognize phishing/suspicious links (1); Keep operating systems and applications updated with security patches (1); Restrict user access privileges (least privilege principle) / block USB ports (1); Implement email filters to block spam and suspicious attachments (1). Reject: 'Install antivirus/anti-malware' (as this is excluded by the question).

1 mark for identifying a key capability of a plotter (e.g., printing on large-format media or continuous rolls). 1 mark for explaining how this meets the company's needs (e.g., ensuring detailed drawings and blueprints remain readable and to scale).

Award 1 mark for a valid feature/reason and 1 mark for explanation/contextualization. Accept: Ability to print continuous line drawings without breaks, printing on A0/A1 sizes. Reject: Just 'it is better' or 'it is faster' without elaboration.

1 mark for identifying a feature of online collaborative documents (e.g., simultaneous editing / real-time updates). 1 mark for explaining why this benefits a multinational team (e.g., prevents multiple conflicting versions being emailed back and forth across different time zones).

Award 1 mark for identifying the benefit/feature and 1 mark for explaining how it helps the team. Accept: Single source of truth, no need to merge changes manually. Reject: 'It is cheaper' or 'It is easier' without a clear reason why.

1 mark for describing a valid security risk (e.g., data interception in transit or server hacking). 1 mark for explaining the impact on the company (e.g., unauthorized third parties gaining access to sensitive corporate information).

Award 1 mark for describing the risk and 1 mark for explaining how it arises or its consequence. Accept: Data transmission interception, cloud provider security breach, unauthorized credential access. Reject: 'Losing internet connection' as this is an availability issue, not a security risk.

1 mark for explaining the limitation or specific role of a firewall (e.g., blocks external network intrusions). 1 mark for explaining how anti-malware complements this (e.g., detects and removes malicious files that bypass the firewall via email attachments or USB drives).

Award 1 mark for explaining the function/limitation of a firewall and 1 mark for how anti-malware addresses this gap. Accept: Malware can bypass firewalls via removable storage (e.g., USB), firewalls do not clean infected files. Reject: Answers that treat them as doing the exact same thing.

When a user browses an e-commerce website, a cookie is used to store state information, such as remembering the items that have been added to the shopping cart, keeping the user logged in, or storing site preferences like language or currency.

Award 1 mark for any correct purpose of a cookie on an e-commerce site, such as:
- Tracking items in a shopping basket/cart.
- Keeping a user logged in/remembering login status.
- Storing user preferences (e.g. currency, theme, language).
- Tracking user browsing habits to recommend products.

Do not accept: 'To store password' (without qualification of security) or general terms like 'to save data' without context.

Consistent navigation (such as keeping the main menu bar in the exact same position with the same links on every page) reduces the cognitive load on visitors. Once a user learns how to navigate the site on the homepage, that knowledge applies to all other pages, making the website faster and more intuitive to use, which prevents frustration.

Award 1 mark for identifying a reason (e.g. increases familiarity / reduces cognitive load / makes the site intuitive) and 1 mark for an explanation linking this to user experience (e.g. so users can locate information quickly without getting confused or lost).

When a user returns to a website, their web browser automatically sends the previously stored cookie file containing a unique identification number back to the web server. The server reads this unique ID, matches it against its database, and retrieves personal preferences or shopping cart state associated with that user to render a customized interface.

Award 1 mark for describing how the cookie/ID is sent from the browser back to the web server (1) and 1 mark for explaining how the server uses this ID to retrieve and apply personalized data (e.g. account settings, saved cart, language preferences) (1).

In a client-server network, resource management, backups, and user access permissions are centralized on a dedicated server. This makes it highly scalable for growing businesses, as administrators only need to configure security settings and perform backups once on the central server rather than manually visiting and configuring each individual client workstation.

Award 1 mark for identifying an advantage of centralization (e.g. centralized backups / central security administration / centralized storage) (1) and 1 mark for explaining why this scales better or is more efficient than a peer-to-peer network (e.g. avoids needing to configure each node individually as the network grows) (1).

The environmental impact of homeworking is twofold. Positive: Since workers perform their duties from home, there is a substantial reduction in daily travel using cars and public transport, leading to lower carbon dioxide emissions. Negative: Heating, cooling, and powering many individual homes throughout the day can consume more total energy than heating and lighting a single centralized office building.

Award 1 mark for describing a positive environmental impact (e.g. reduced car commuting leads to less air pollution / lower carbon footprint) (1) and 1 mark for describing a negative environmental impact or a detailed trade-off (e.g. increased domestic electricity/gas consumption for multiple homes / increase in electronic waste from duplicate home office setups) (1).

To achieve high marks, the discussion must be balanced, covering both advantages and disadvantages for both stakeholder groups. Employers benefit from lower operational costs as smaller physical offices are needed. They can also hire staff from anywhere in the world. However, they may find it harder to supervise staff and must address security vulnerabilities caused by employees using home internet connections to access sensitive company data. Employees benefit from the elimination of travel time and expense, allowing for a better lifestyle balance. Conversely, they may suffer from isolation due to a lack of face-to-face social contact with colleagues, and find it hard to 'switch off' from work when their office is in their home space.

Level 1 (1-3 marks): The candidate identifies basic points with little or no explanation. There may be a focus on only one stakeholder (e.g., just the employee) or only advantages. The writing lacks structure and uses minimal technical terminology. Level 2 (4-6 marks): The candidate explains some advantages and disadvantages for both employers and employees. There is some analysis of the impact of ICT, and the discussion is mostly balanced. The answer is structured and uses some appropriate terminology. Level 3 (7-8 marks): The candidate provides a detailed, fully balanced discussion covering both advantages and disadvantages for both parties. There is a clear, analytical understanding of how ICT enables this transition and the associated risks. The response is well-structured, coherent, and uses precise ICT terminology throughout.

To reduce the environmental impact of disposing of redundant digital devices, individuals can:
1. Donate or sell older, still-functioning devices to charities, schools, or other users so they continue to be used instead of being discarded.
2. Take broken or obsolete devices to specialized, certified electronic waste (e-waste) recycling facilities where hazardous materials can be safely extracted and useful components recovered.

Award 1 mark for each valid method stated, up to a maximum of 2 marks.

Suggested answers include:
- Donating working devices to charity/schools/others.
- Selling working devices for reuse.
- Taking devices to official/specialist e-waste recycling centres.
- Returning devices to manufacturers/retailers via trade-in or take-back schemes.
- Repairing or upgrading existing devices rather than disposing of them.

Do not accept:
- Just 'throwing them away' or 'putting them in the bin'.
- Unsafe disposal methods such as 'burning them' or 'burying them'.

Rural areas are often less populated, making it expensive for telecommunications companies to install high-speed fiber-optic cables or 5G masts (1 mark). Consequently, rural residents are left with slow or unreliable internet access, which prevents them from accessing educational, financial, or employment opportunities online that urban residents can easily access (1 mark).

Award 1 mark for identifying the cause related to lack of infrastructure (e.g. high cost of laying cables in rural areas / lack of high-speed connection towers). Award 1 mark for explaining how this leads to the digital divide (e.g. results in slow/no internet, limiting access to essential online services compared to urban areas).

Obsolete electronic devices contain toxic chemicals and heavy metals, such as lead and mercury (1 mark). When buried in a landfill, these harmful substances can leach out into the surrounding soil and contaminate local groundwater supplies, harming ecosystems (1 mark).

Award 1 mark for identifying that electronic devices contain toxic chemicals/metals that can leak/leach out. Award 1 mark for explaining the impact of this leakage on the environment (e.g. contamination of soil/groundwater, harming plants or wildlife).

Web crawlers are automated programs that travel the internet by following hyperlinks from one web page to another (1 mark). As they visit each page, they copy the text and metadata and send this information back to the search engine's servers to be indexed (1 mark).

Award 1 mark for describing how crawlers navigate (following hyperlinks from page to page automatically). Award 1 mark for describing the collection of data (sending page content/text/keywords back to the search engine to be indexed/saved).

The right to erasure allows individuals to demand that an organisation permanently delete their personal data if it is no longer required for the purpose it was gathered (1 mark). This protects individuals by ensuring that outdated, sensitive, or irrelevant personal information is not stored indefinitely, reducing the risk of a data breach or identity theft (1 mark).

Award 1 mark for explaining the action allowed by the right (requesting the deletion of personal data when no longer needed). Award 1 mark for explaining how this benefits/protects the individual (e.g. reduces risk of data leaks, stops unnecessary storage of personal information, prevents identity theft).

Indicative content for the discussion:

Benefits to Individuals:
- More convenient, personalised user experiences (e.g., recommended products, saved preferences).
- Streamlined services (e.g., autofill shipping/payment details leading to faster transactions).

Drawbacks to Individuals:
- Serious privacy risks if data is misused or shared without consent.
- Increased vulnerability to identity theft, financial fraud, or phishing attacks if the organisation suffers a security breach.
- Unwanted targeted advertisements that can feel intrusive.

Benefits to Organisations:
- Ability to perform deep data analytics to understand customer trends, improve products, and increase sales.
- Targeted marketing campaigns that yield higher conversion rates.
- Customer loyalty through personalised rewards and engagement.

Drawbacks/Responsibilities for Organisations:
- High cost of implementing and maintaining robust cybersecurity systems to prevent unauthorized access.
- Liability to severe legal fines and loss of consumer trust if they fail to protect customer data.
- Resource-heavy requirement to keep data accurate and up-to-date.

Integration of Data Protection Principles:
- Security: Organisations must use technical measures (encryption, access controls) to protect personal data.
- Minimisation: Organisations should only collect data that is strictly necessary for their stated purpose, limiting unnecessary risk.
- Purpose Limitation: Data collected for one reason cannot be used for unrelated marketing purposes without explicit consent.
