Computing

Computing is the process of using computer technology to complete a given goal-oriented task. Computing may encompass the design and development of software and hardware systems for a broad range of purposes - often structuring, processing and managing any kind of information - to aid in the pursuit of scientific studies, making intelligent systems, and creating and using different media for entertainment and communication.

Components and emerging trends in digital systems

KEY TERMS:- Digital system: can consist of a single device, a collection of devices or a network. It is used to transform data into information. - Emerging technologies: Tech that is perceived to be capable of making significant change within society. - Datafaction: Process of turning aspects of everyday life into measerable data. Example: Hours of sleep per night. - Automation: When a procedure is done without the need of human intervention.

Example of a regular household appliance that has been integrated with technology is the refrigerator. Smart refrigerators include touchscreen, internal cameras, a range of temperature-controled zones and connectivity through a smart app.

The functionality a smart refrigerator offers may include the ability to:

• Control temperature by drawer or compartment
• View the contents of the refrigerator using an internal camera
• Send alerts when the refrigerator encounters a problem
• Control other settings using a smartphone app

Functions and capabilities of digital systems

KEY TERMS:- Assistive technologies: Allows the completion of tasks that would not normally be able to be completed, or made easier and safer to complete day to day activities. Example:Monility aids: Devices such as wheelchairs to assist navigation. - Financial services: Range of technology used within the financial service industry. Example: Customer service: Chatbots or automated voice and text systems being used as an initial interface with customers. - Global positioning system (GPS): Uses network of satellites that provide location and time data to any c onnective device. Example: GPS satellite --> GPS unit --> Cell tower --> Server --> User - Robotics: A robot is a device that can complete specific tasks with autonomy. Example: Robot vacuum cleaner. - Traffic management: Process used to effeciently and effectively control the flow of vehicles. Example: Cameras used in traffic management systems

Goals and objectives

KEY TERMS:- Goal: Broad statement of the desired result that a digital system is expected to achieve. Example: A goal for a year 11 student would be to receive an A grade in Applied computing. - Objective: How a goal will be achieved. Tend to be specific and measurable. Example: An objective for a year 11 student to receive an A grade in applied computing is for them to recieve no less than 90% of each assesment task.

Example: Goals and objectived of digital systems: A swarm od nanosatellites used to take images of Earth's surface might have the following goals and objectives. Goal :

Objectives:

• 16 nanosatellites are used each day to take imagery of the Earth's surface
• Each satellite orbits around 500 km above the Earth
• Each satellite oribts earth on one eight orbit paths
• Each satellite completes one rotation of Earth every 48 hours
• Each satellite takes an image every two seconds
• Images are sent back to a base station each hour
• A composite image of Earth is produced each day

• To develop a composite image of Earth's entire surface daily

Economic issues involving emerging technologies

KEY TERMS:- Economics: Study of the production, distribution and comsumption of goods and services. Economic issues include:

• Acces: Technology becoming more affordable
• Deskilling: when a skilled worker is replaced
• Job losses: When a job formerly completed by a human in an organisation is no longer needed.
• Sustainability: Process of managing change in a balanced and controlled way so that other factors such as natural resources, climate, pollution levels and economic resources are not negatively affected

Example: The distribution and lifespan of smartphones Issues: Solutions:

• Sustainability
• Ethical issue = organisations designing and sellign smartphones are making significant profits as a result of the low costs of manufactoring devices in developing countries

• Using recycled parts
• working with non- profit industries

Impact of current and emerging technologies

KEY TERMS:- Issues and impact an be related to:

• Automation: Process that can be completed without the need for human intervention

• Cyberbulling: Digital system is used to threaten, harass or intmidate another individual

• Human interactions: involves people communicating with other people
• Interpersonal skills: Skills that are required ti interact and communicate effectively with other

Impacts

Key legislation and emerging technologies

KEY TERMS:- Legislation is the body of laws, created by governments, that individuals and organisations in each government’s jurisdiction must follow. - Acts of Parliament (or pieces of legislation) that have an effect on emerging technologies include the: • Privacy Act 1988 • Privacy and Data Protection Act 2014 • Health Records Act 2001 • Copyright Act 1968.

Impact of current and emerging technologies
