Mobile Computing
Mobile Computing
Refers to the ability to access and process data or perform computing tasks using portable devices such as smartphones, tablets, and laptops.
Key Features
- Portability: Devices like smartphones, tablets, and laptops can be used anywhere.
- Wireless Connectivity: Relies on Wi-Fi, cellular networks, and Bluetooth for communication.
- Battery Dependency: Devices operate on limited battery power.
- Resource Constraints: Limited processing power and storage compared to traditional computers.
Advantages and Challenges
- Advantages:
- Flexibility: Users can work from any location.
- Real-Time Access: Immediate access to information and services.
- Challenges:
- Security Risks: Mobile devices are prone to theft and unauthorized access.
- Connectivity Issues: Performance depends on network availability.
Using a smartphone to check emails, navigate with GPS, or stream videos while on the move.
Ubiquitous Computing
Ubiquitous computing
Also known as pervasive computing, is the concept of embedding computing technology into everyday objects and environments, making it seamlessly integrated and accessible.
Key Features
- Invisibility: Devices operate seamlessly in the background.
- Context-Awareness: Systems adapt to the user's environment and behavior.
- Interconnected Devices: Relies on the Internet of Things (IoT) for communication.
Advantages and Challenges
- Advantages:
- Automation: Reduces manual intervention in daily tasks.
- Personalization: Systems adapt to individual preferences.
- Challenges:
- Privacy Concerns: Continuous data collection can lead to privacy issues.
- Complexity: Integrating diverse devices requires robust infrastructure.
Smart homes where lights, thermostats, and security systems are controlled automatically based on user preferences and behaviors.
Peer-to-Peer Network
Peer-to-peer (P2P)
A decentralized network architecture where each participant (peer) acts as both a client and a server, sharing resources directly with other peers without relying on a central server.
Key Features
- Decentralization: No central server, all nodes are equal.
- Resource Sharing: Peers share files, processing power, or bandwidth.
- Scalability: Easily accommodates more nodes without significant changes.
