Explain the following static channel allocations mechanisms: i) TDMA ii) FDMA

Static Channel Allocation: TDMA and FDMA Explained

Time Division Multiple Access (TDMA)

  • Divides time into slots.
  • Each slot assigned to a user.
  • Users transmit only during their assigned slot.
  • Improves efficiency compared to FDMA in some scenarios.
  • Prone to synchronization issues.
  • Vulnerable to burst errors.

Frequency Division Multiple Access (FDMA)

  • Divides the available bandwidth into frequency channels.
  • Each user assigned a separate channel.
  • Simultaneous transmission possible on different channels.
  • Simple implementation.
  • Less efficient use of bandwidth compared to TDMA in some cases.
  • Guard bands needed to prevent interference.

What is architectural design? Discuss different style and patterns of architecture.

Mastering Software Architecture: Styles and Patterns What is Architectural Design? Blueprint for software systems. Defines structure, behavior, and interactions. Guides development, ensuring scalability and maintainability. Addresses high-level concerns, not implementation details. Impacts performance, security, and cost. Architectural Styles Layered Architecture: Organizes system into horizontal layers (presentation, business logic, data access). Microservices Architecture : Breaks down application into small, independent services. Event-Driven Architecture: Components communicate asynchronously via events. Space-Based Architecture: Distributes data and processing across geographical locations. Client-Server Architecture :** Classic model with clients requesting services from servers. Architectural Patterns Model-View-Controller (MVC):  Separates concerns into model (data), view (presentation), and controller (logic). Model-View-ViewModel (MVVM): Variation o...

State the need for software configuration review.

The Indispensable Software Configuration Review: Why It Matters Early Problem Detection Prevents costly late-stage bug fixes. Identifies inconsistencies early in the development lifecycle. Reduces integration challenges. Enhanced Collaboration Improves communication between development teams. Facilitates knowledge sharing among team members. Ensures everyone is on the same page regarding the software configuration. Improved Quality Assurance Helps meet compliance requirements. Reduces the risk of security vulnerabilities. Ensures software stability and reliability. Better Traceability and Auditability Simplifies future maintenance and updates. Provides clear documentation for compliance audits. Allows for easier rollback in case of errors. Reduced Risks Minimizes potential for configuration drift. Prevents deployment failures and downtime. Improves overall project success rate.

Define Engineering Ethics. Distinguish between ethics, laws and morals.

Navigating the Ethical Minefield: Engineering Ethics in IT Defining Engineering Ethics The study of moral issues and decisions confronting individuals and organizations engaged in engineering. Application of ethical principles to engineering practice, design, and research. Focus on responsible innovation, safety, and societal well-being in engineering projects. Consideration of potential impacts on stakeholders – users, environment, society. Ethics vs. Laws vs. Morals Ethics: Formal system of principles governing conduct; professional codes and guidelines. Laws: Societal rules enforced by governmental authority; legally binding requirements. Morals: Individual beliefs and values about right and wrong; personal sense of what is good/bad. Distinguishing the Three in IT Ethics:  IT professional codes (ACM, IEEE) specify confidentiality, data security, intellectual property respect. Laws:  Copyright laws, data privacy regulations (GDPR, CCPA), cybercrime statut...
