Level 0: Absolute IT and Networking Basics

This page exists so the roadmap truly starts from zero. No Cisco command is useful until the basic language of computers, networks, IP addresses, ports, and troubleshooting is clear.

# Goal

Level 0 pass condition: I can explain a small network, assign IP addresses, test connectivity, use basic Windows and Linux commands, and document one broken-network ticket without guessing.
Proof rule: every task must include a written note. Add a screenshot when the task has a visible result. Add a short video when the task is a process, such as opening Device Manager, using terminal commands, or explaining what you checked.

# Proof-of-Work Tasks

Use these cards to prove that each foundation task was actually done. Notes and small attachment previews save locally in your browser. For permanent proof, export the note and commit the screenshot/video files into the GitHub repo.

Task 01 — Computer, CPU, RAM, disk, NIC and OS

Explain what each part does and why a network issue can still be caused by the device itself.

Not saved yet.

Task 02 — Windows basics

Open Settings, Device Manager, Services, Event Viewer and Network adapters. Record what each tool is used for during troubleshooting.

Not saved yet.

Task 03 — Linux basics

Use terminal basics, check files, permissions and services. This prepares you for servers, routers, cloud labs and logs.

Task 04 — Files, folders, paths, logs and screenshots

Create a simple folder structure for evidence and prove you can save notes, screenshots and logs cleanly.

# Move Forward Gate

Before CCSTI must be able to prove
ExplainIP, DNS, DHCP, gateway, router, switch, firewall, port, protocol.
Use commandsRun ping, ipconfig, nslookup and traceroute, then explain the result.
FixOne broken IP or DNS ticket with root cause and verification.
DocumentWrite a simple ticket note: symptom, checks, fix, proof.
