Learn Networking vs PAKEDOU

This app is a great resource to learn about Computer Networking and Cisco Switches. The app is engineered to make users perfect understanding common Computer Networking questions by studying for a very short amount of time. Audio functionality and bookmarking is available throughout the app on chapter, section, study mode and quiz modes. The app will help you learn the correct pronunciation of terminologies used in Computer Networking using English language. Following are the main features of this app 1. Supports pronouncing Computer Networking terminologies in English Language 2. Uses Text to Speech Engine for Audio Functionality 3. Quizzes 4. Study Mode 5. Bookmarking Study Flashcards and Quiz Questions 6. Progress Indicators for Every Chapter 7. Visualization for Overall Progress

PAKEDOU is a simulation app that visualizes network packet flow in real time. Place and connect 14 types of network devices - Router, L2 Switch, Firewall, Load Balancer, NAT, DNS Server, WAF, CDN, and more - on a canvas, and watch HTTP, DNS, ICMP, ARP, and TCP packets flow through your topology with animations. [Who is this for?] - Anyone who wants to visually understand how networks work - Students preparing for CCNA, CompTIA Network+, or similar certifications - Trainers looking for hands-on teaching material for new engineers - Anyone who wants to learn routing, NAT, and VLAN by doing [Two modes for progressive learning] Simple Mode: Packets are delivered just by connecting cables. Routing and MAC resolution are automatic. Even networking beginners can start exploring immediately. Realistic Mode: Simulates real network behavior. Requires routing table configuration, default gateways, ARP resolution (broadcast request -> unicast reply), TCP 3-way handshake (SYN -> SYN+ACK -> ACK), and DNS name resolution. [Educational feedback] When a packet is dropped, the app shows "Why it failed" with an explanation and a hint to fix it. On timeout, a device-type-specific explanation is auto-generated based on where the packet got stuck. [Key Features] - 14 network device types (Client, Server, Router, L2/L3/VLAN Switch, Firewall, LB, NAT, DNS, WAF, CDN, Proxy, Internet) - Color-coded protocol display: HTTP, DNS, ICMP, ARP, TCP - Device configuration (IP/subnet, routing table, ACL rules, VLAN ID, DNS A records, NAT rules, etc.) - Tap a log entry to expand L2-L7 packet details - Manual/auto packet send (choose protocol, source, destination) - Domain-based send (auto DNS query -> HTTP send for real-world flow experience) - SQL injection and XSS attack packets (for WAF testing) - Save/load topology (Free 1 slot / Pro 5 slots) - Playback speed control (0.25x-10x) - Pinch-zoom and pan navigation - First-launch tutorial (6 swipeable pages, each with a built-in Canvas animation) - Starter topology auto-load (Client -> L2 Switch -> Server placed right after the tutorial) - UI in 16 languages (Japanese, English, Simplified Chinese, Traditional Chinese, Korean, Spanish, Brazilian Portuguese, German, French, Hindi, Indonesian, Russian, Italian, Turkish, Thai, Vietnamese) auto-detected from device locale [Today's Outage] Every day, one broken network arrives. Send packets, read the logs, fix the settings, then check your answer. Every challenge is verified by the simulator itself before it is published: it is guaranteed to be broken and guaranteed to be fixable. Inside the day's challenge, Free users can also operate Pro devices (Firewall, DNS Server, VLAN Switch, Load Balancer, WAF). After clearing it, share your move count, hints used and time. Offline, 14 bundled challenges are always available. Story, hints and explanation come in all 16 languages. Pro users can also replay the past 30 days. [Free / Pro] Free: 5 device types, max 5 devices, 1 save slot, with ads Pro (one-time purchase, price shown in the store): all 14 device types, unlimited devices, 5 save slots, no ads, detailed logs, past 30 days of Today's Outage Already purchased? Tap "Pro" in the toolbar, then "Restore Purchase". [Privacy] Topologies you create are stored locally on the device, and the app itself does not send your data to external servers. The Free version displays Unity Ads, whose SDK collects device identifiers and similar data. See our privacy policy for details. Ads are shown only after you choose whether to allow personalized ads on first launch, and you can turn personalized ads off at any time under "?" > "Ad settings".
