IB Computer Science Topic C.3.4 Role of Distributed Systems in Web Growth Revision Notes (SL/HL) | RevisionDojo

Distributed Systems and Web Growth

The centralized web, where data and control reside in a few powerful entities, faces challenges such as:
1. Single points of failure
2. Limited scalability
3. Concerns over privacy and control
Distributed systems are catalyzing a shift towards a more decentralized web, where power is spread across many independent nodes.

Distributed Systems Enable Decentralization

Distributed systems are inherently decentralized by design, operating without a single point of control.
This architecture aligns perfectly with the goals of a decentralized web, where users have more control over their data and interactions.

Key Features of Distributed Systems Driving Decentralization

Peer-to-Peer Networks:
1. Distributed systems often rely on peer-to-peer (P2P) networks, where nodes communicate directly without intermediaries.
2. This eliminates the need for central servers, reducing the risk of censorship and single points of failure.
Redundancy and Fault Tolerance:
1. Data and services are replicated across multiple nodes, ensuring that the system remains operational even if some nodes fail.
