Wi-Fi standards and security in Intro to Computing - Flowchart & Logic Diagram

Process Overview

This flowchart explains how Wi-Fi devices connect securely using different Wi-Fi standards and security methods. It shows the steps a device takes to choose the right Wi-Fi standard and apply security to protect the connection.

Step-by-Step Trace - 8 Steps

Step 1: Device scans for Wi-Fi networks nearby.

Step 2: Device detects Wi-Fi standards each network uses (e.g., 802.11n, 802.11ac).

Step 3: Device checks if it supports the network's Wi-Fi standard.

Step 4: If compatible, device selects the strongest Wi-Fi standard available.

Step 5: Device checks the network's security type (WEP, WPA, WPA2, WPA3).

Step 6: Device verifies if it supports the network's security protocol.

Step 7: If supported, device applies the security protocol (e.g., WPA2 encryption).

Step 8: Device connects securely to the Wi-Fi network.
