Mobile Computing Architectures:
Mobile computing architectures encompass the various ways in which mobile devices and networks are organized to support mobile communication and applications. The R20 syllabus delves into the following key aspects of mobile computing architectures:
Client-Server Architecture:
This traditional architecture consists of a centralized server that provides services to multiple clients. In the context of mobile computing, the server may be located in a fixed location or in the cloud, while the clients are mobile devices. This architecture is commonly used for accessing web-based services, email, and file sharing.
Peer-to-Peer Architecture:
In a peer-to-peer architecture, all devices are considered equal, and they can communicate and share resources directly with each other without the need for a central server. This architecture is often used for mobile ad hoc networks (MANETs), where devices can form temporary connections with each other to share data and resources.
Hybrid Architecture:
Hybrid architectures combine elements of both client-server and peer-to-peer architectures. In this model, a central server provides core services, such as authentication and data storage, while mobile devices communicate and share resources directly with each other for specific tasks. This architecture offers a balance between centralized control and distributed processing.
Mobile Cloud Computing Architecture:
Mobile cloud computing architectures leverage the cloud to provide computing resources, storage, and services to mobile devices. In this model, mobile devices offload computationally intensive tasks and data storage to the cloud, enabling them to access and utilize powerful resources and services without the need for local processing and storage capabilities.
Understanding these mobile computing architectures is crucial for students to grasp the underlying principles and design considerations for developing and deploying mobile applications and services.
Mobile Application Development:
Mobile application development is a critical aspect of mobile computing, enabling the creation of software applications specifically designed for mobile devices. The R20 syllabus covers the following key aspects of mobile application development:
- Mobile Application Platforms:
This section introduces the various mobile application platforms, including Android, iOS, and Windows Phone, and their respective development environments and tools.
- Mobile Application Design Principles:
Students learn about the fundamental principles and best practices for designing user interfaces and user experiences tailored for mobile devices, considering factors such as screen size, touch input, and context-awareness.
