IT glossary
Dictionary of IT terms, jargon-free.
Clear definitions of the terms we use in our work: AI, development, infrastructure, Mercado Público, and SEO. Written for humans.
Artificial intelligence
LLM (Large Language Model)
Large language model trained to understand and generate text, like ChatGPT, Claude, or Gemini.
RAG (Retrieval-Augmented Generation)
Technique that connects an LLM to your own documents so it answers with your information, not its training.
AI Agent
Program with an LLM that makes decisions and executes actions — search, write, call APIs — to fulfill a goal.
Prompt
The text instructions an LLM receives to generate its response. Well-designed, they make all the difference.
Vector database
Specialized storage for semantic similarity search, not exact word match. A pillar of RAG.
MCP (Model Context Protocol)
Open standard to connect AI agents with external tools and data. Driven by Anthropic.
SEO & discoverability
LLM SEO (LLM optimization)
Set of practices to get a site cited by LLMs like ChatGPT, Perplexity, Claude, or Gemini.
llms.txt
Text file at the site root that tells an LLM what you are and where the important information lives.
Schema.org / JSON-LD
Standard vocabulary to describe entities (company, product, person) that search engines and LLMs understand.
Software development
MVP (Minimum Viable Product)
Simplest possible version of a product that already delivers real value and lets you learn from the market.
Sprint
Short development cycle (typically 1-2 weeks) with a concrete goal and a demonstrable deliverable.
Discovery
Initial project phase where business, constraints, and real scope are understood.
API
Interface that lets two systems talk to each other — the foundation of every modern integration.
Webhook
HTTP call one system sends to another when an event occurs. An efficient alternative to polling.
System integration
Making two or more systems talk so your team doesn't have to do repetitive manual work.
Infrastructure
SLA (Service Level Agreement)
Formal agreement on service level: guaranteed uptime, incident response times, etc.
Uptime
Percentage of time a service is available. 99.9% monthly ≈ 43 min of allowed downtime.
Monitoring
Continuously observing system health (uptime, errors, performance) to detect issues before users do.
Mercado Público
Mercado Público (Chile)
Chilean state platform for public procurement and tenders. Mandatory channel for selling to the public sector.
ChileProveedores
Official electronic registry of suppliers to the Chilean state. Free registration required to bid.
DTE (Electronic Tax Document)
Electronic invoices, receipts, and credit notes required by Chile's SII.
