• Medical Devices (Patient monitoring systems, diagnostic tools)
• Industrial Automation (Robotics, factory control systems)

Embedded software prioritises real-time responsiveness, performance optimisation and reliability to ensure seamless functionality in critical applications.

Cloud computing means delivering computing resources like storage, processing power and software applications over the internet, providing organisations with scalable, cost effective and manageable IT solutions.

Cloud Service Models:

• Infrastructure as a Service (IaaS): Offers virtualised hardware resources like virtual machines, storage and networks.
• Platform as a Service (PaaS): Provides development platforms and environments to build, test and deploy applications without infrastructure management.
• Software as a Service (SaaS): Delivers software applications over web browsers, reducing need for on-premise installations and maintenance.

Serverless Computing

Serverless computing abstracts infrastructure management, allowing developers to execute event driven code on-demand through services like AWS Lambda, Azure Functions and Google Cloud Functions. This approach simplifies development and scalability so organisations can focus on software innovation.

Data science involves techniques to collect, analyse and interpret large datasets to get actionable insights and inform decision making. Data scientists use statistical analysis, machine learning algorithms and data visualisation tools to manage complex data.

• Artificial Intelligence: AI means developing systems that can perform tasks that typically require human intelligence like natural language processing, speech recognition, image analysis and autonomous decision making.
• Machine Learning (ML): Machine learning algorithms enable systems to automatically learn and improve from experience without explicit programming. ML methodologies include supervised learning (training with labelled data), unsupervised learning (identifying patterns in unlabelled data) and reinforcement learning (decision making through interaction and feedback).
• Internet of Things (IoT): IoT development connects physical devices to the internet, automates, monitors and exchanges data in real-time. IoT applications range from smart home devices and wearable health monitors to agricultural management and industrial process control.

DevOps combines software development and IT operations, focusing on collaboration, automation, continuous integration and continuous deployment (CI/CD) to improve software quality, speed up delivery cycles and operational efficiency.

• Continuous Integration (CI): Continuous integration involves merging code changes from developers into a central repository as frequently as possible where automated tests detect and resolve integration issues quickly ensuring software stability and quality.
• Continuous Deployment (CD): Continuous deployment automates software releases to production environments with minimal human intervention. Tools like Jenkins, GitLab CI/CD, Kubernetes, Docker help in automating this process and improve speed and reliability.

Security software development aims to create software that protects data, systems and users from cyber threats and vulnerabilities. Security developers focus on secure coding practices, robust encryption, strong authentication protocols and adherence to industry standards.

Security Software Best Practices:
