Technical Glossary

A structured set of protocols and definitions allowing software applications to communicate and exchange data and commands.

A Layer 2 communication protocol that resolves local IP addresses into physical MAC hardware addresses on local area networks.

A globally distributed system of proxy edge servers caching assets close to users to reduce latency and origin server load.

An IP address allocation scheme using slash notation (e.g. /24) to create variable-length subnet masks flexibly.

A browser security mechanism that uses HTTP response headers to allow scripts on one domain to access resources on another domain safely.

The hierarchical naming system that translates human-readable hostnames into numerical IP routing addresses.

The stateless, application-layer client-server request and response protocol foundational to the World Wide Web.

The secure version of HTTP that encrypts web sessions using Transport Layer Security (TLS) cryptography.

The fundamental network layer protocol that defines packet header addressing and routing across internetworks.

A networking method that maps multiple local private IP addresses to a single public IP address to conserve IPv4 space.

An architectural style for designing networked APIs based on stateless operations and standardized HTTP methods.

A web security vulnerability where a backend server is manipulated into making unauthorized network requests to internal systems.

A connection-oriented transport layer protocol guaranteeing reliable, ordered packet delivery via handshake mechanisms.

The cryptographic protocol providing end-to-end encryption, data integrity, and server authentication over computer networks.

A field in DNS records and IP headers specifying the timeframe in seconds that cached data remains valid before refresh.

A connectionless, lightweight transport protocol prioritized for low-latency streaming and real-time gaming without handshake delays.

A formatted address string that identifies a web resource and specifies the protocol used to access it.

An encrypted point-to-point network tunnel extending a private network across public internet infrastructure.
