Algorithm Laboratory

This module addresses the core weakness identified in Q4. Practice Binary Search (for sorted lists) vs. Linear Search (for any list) to understand efficiency and trace logic.

1. Select Algorithm

2. Select Scenario

Binary Search requires the array to be sorted. Linear Search does not, but it is much slower for large datasets.

🏗️ Infrastructure Scenarios

Small Office Floor

Star Topology + Cat6 Copper

Justification: A central switch allows high-speed 1Gbps connections. If one cable fails, the rest of the network stays online. Copper is cost-effective for distances under 100m.

Inter-Building Link

Point-to-Point + Fiber Optic

Justification: Fiber uses light pulses, making it immune to electrical interference between buildings. It supports 10Gbps+ speeds over many kilometers without signal loss.

Hospital/School Campus

Mesh Topology + Wi-Fi 6

Justification: Provides high mobility for users. Mesh topology allows nodes to route traffic around dead zones or failed units, ensuring constant uptime for critical applications.
