IT learning tools, quizzes, and operational templates for IT professionals
Learning and checklist tools on it.you bridge the gap between reference material and operational knowledge. The daily IT quiz tests and reinforces foundational knowledge across six topic areas — networking, Linux, security, web, DevOps, and databases — with explanations after every answer. The template builders generate structured, ready-to-use documents for incident postmortems, runbooks, server room audits, and onboarding workflows.
These tools are designed for both individual learning and team operations. A junior sysadmin can use the daily quiz to build knowledge systematically. A senior engineer can use the runbook builder to generate documentation that keeps incidents manageable. An IT manager can use the onboarding checklist to ensure every new team member is set up consistently.

Key concepts
Runbook — A step-by-step operational procedure for a specific task, service, or incident scenario. Good runbooks include prerequisites, steps, expected outcomes, and rollback procedures. They reduce cognitive load during incidents.
Postmortem (incident review) — A structured analysis of an incident after it is resolved, focused on understanding root causes and implementing systemic improvements. Blameless postmortems focus on processes and systems, not individual fault.
Onboarding checklist — A structured list of tasks and resources for new team members. Covers account access, tool setup, documentation reading, introductions, and first-week objectives. Reduces time-to-productivity.
Server room checklist — A periodic audit of physical and environmental infrastructure: power redundancy, cooling, cabling, labelling, security access, and disaster recovery readiness.
Spaced repetition — A learning technique that schedules review of material at increasing intervals based on how well you know it. The IT quiz implements a form of spaced repetition by tracking which questions you've seen and surfacing unseen ones first.
Frequently asked questions
What topics does the IT quiz cover?
The quiz covers six categories at three difficulty levels: Networking (DNS, CIDR, protocols), Linux (commands, permissions, processes), Security (hashing, encryption, vulnerabilities), Web & HTTP (status codes, REST, CORS), DevOps (Docker, Kubernetes, CI/CD), and Databases (SQL, ACID, CAP theorem). 120+ questions total with no repetition until you've seen them all.
What is a runbook and why is it important?
A runbook is a step-by-step guide for performing a specific operational task or responding to a specific incident type. Good runbooks reduce the cognitive load during high-stress incidents, enable less experienced team members to handle routine tasks, and ensure consistency across team members.
What should be in a blameless postmortem?
A good postmortem includes: incident timeline, impact assessment, root cause analysis, contributing factors, what went well, what went wrong, action items with owners and due dates, and lessons learned. The "blameless" aspect means focusing on systemic issues rather than individual mistakes.
How do I prepare for CompTIA certifications using it.you?
The IT quiz covers topics across CompTIA A+, Network+, Security+, and Linux+ syllabuses. Use the category filter to focus on specific domains, and the difficulty filter to advance from beginner to intermediate to advanced questions. The Linux Commands Reference and HTTP Status Code Reference are useful companion study materials.
What is the difference between a runbook and a playbook?
A runbook covers a specific operational procedure for a known task (e.g., "How to deploy a new release"). A playbook covers broader response strategies for a class of incidents (e.g., "How we respond to a data breach"). Runbooks are tactical; playbooks are strategic.
