About Itchen Tech Guide
Independent plain-language guides to IT careers, help desks, security basics, data, cloud and how technology is used in organizations.
Who this site is for
Newcomers, students and working professionals who want clear general explanations of IT topics.
How the guides are written
- Answer first. Each guide leads with the direct answer, then explains the why and the how.
- Practical numbers. Concrete values you can use, with ranges rather than false precision.
- Connected, not repeated. Short, focused articles link to the in-depth guide for their topic, so you can go as deep as you need.
- Dated. Every article shows when it was published.
Please note
General information, not professional advice; check security and compliance decisions against your own situation and qualified guidance.
