A1 Modern Technologies – BTEC Tech Award in Digital Information Technology

Key Concepts

• Communication technologies and how they enable connectivity
• Cloud storage and cloud computing for data access and collaboration
• Selection of platforms and devices for different business needs
• Use of hybrid systems combining on-premises and cloud solutions
• Implications of modern technologies for organisations

Communication Technologies

• Ad Hoc Networks: Temporary wireless connections created without fixed infrastructure, such as mobile hotspots or Bluetooth sharing.
• Advantages: Easy to set up, flexible, useful in emergencies or short-term collaboration.
• Disadvantages: Limited range, weaker security, slower speeds, and higher battery consumption.
• Open Networks: Networks that do not require authentication (e.g., public Wi-Fi). These pose security risks such as data interception and malware injection.
• Security Solutions: Use VPNs, HTTPS, firewalls, and two-factor authentication to reduce risks.

Cloud Technologies

• Cloud Storage: Saving data on remote servers accessed via the internet (e.g., Google Drive, OneDrive).
• Advantages: Accessible anywhere, easy to share, automatic backup.
• Disadvantages: Requires internet access, potential privacy concerns, possible subscription costs.
• Cloud Computing: Running software and services over the internet (e.g., Microsoft 365, Google Workspace).
• Advantages: Reduces need for powerful local hardware, supports collaboration.
• Disadvantages: Dependent on reliable internet, potential data security risks.

Platform and System Selection

• Factors Affecting Choice: Cost, compatibility, scalability, performance, and user requirements.
• Businesses must choose platforms (mobile, desktop, web) that best suit their users and data needs.
• Hybrid Systems: Combine on-premises and cloud resources for flexibility and control.

Organisational Implications

• Security: Organisations must protect data through encryption, authentication, and access control.
• Data Protection: Compliance with regulations like GDPR is essential to protect user privacy.
• Productivity: Cloud and modern communication tools enable remote working and collaboration.
• Cost Management: Subscription-based services can reduce upfront costs but add long-term expenses.

Advantages & Disadvantages Summary

• Advantages: Improves flexibility, supports remote work, reduces local storage needs, encourages innovation.
• Disadvantages: Dependent on internet, security vulnerabilities, ongoing costs, and data privacy risks.
