IB Computer Science Topic C.4.6 Future of Web Infrastructure Revision Notes (SL/HL) | RevisionDojo

Definition

Network Architecture

The design and structure of a computer network, including its physical and logical layout, communication protocols, and data transmission methods.

Definition

Protocol

A set of rules that defines how data is transmitted and received over a network.

Definition

Standards

An agreed-upon specification that ensures compatibility and interoperability between different systems and technologies.

The future of the web depends on the evolution of its underlying infrastructure, which includes network architecture, protocols, and standards.
These components ensure the web remains scalable, secure, and accessible as it grows.

Network Architecture

Scalability

As the number of internet users and connected devices grows, network architecture must support scalability.
This involves:
1. Decentralization: Reducing reliance on central servers to prevent bottlenecks.
2. Edge Computing: Processing data closer to the source to reduce latency.

Note

Edge computing is becoming essential for applications like autonomous vehicles and smart cities, where real-time data processing is critical.

Security

Security is a major concern in network architecture.
Future developments include:
1. Zero Trust Models: Assuming no device or user is trusted by default.
2. Quantum-Resistant Encryption: Preparing for the potential threat of quantum computers breaking current encryption methods.

Common Mistake

Note

Many students assume that encryption is a one-time solution.
In reality, encryption methods must evolve to counter new threats, such as quantum computing.

Energy Efficiency

With the rise of data centers and cloud computing, energy efficiency is crucial.
Techniques include:
