WAF (Web Application Firewall)

A WAF filters, monitors, and blocks HTTP traffic to and from a web application. A WAF is differentiated from a regular firewall in that a WAF is able to filter the content of specific web applications while regular firewalls serve as a safety gate between servers.

VPN (Virtual Private Network)

An isolated network of computers using existing infrastructure, such as a Local Area Network (LAN) or Wide Area Network (WAN or Internet) to securely connect to each other. When you use a public WiFi network, for instance, your device and data are theoretically accessible by everyone else on the network. When using a VPN, you’re still able to access the internet through the public network, but are shielded by the VPN. 

TXC (TransXChange)

The UK national standard for exchanging bus schedules and related data. It is used for:

  • the electronic registration of bus routes
  • the Traffic Area Network
  • the exchange of bus routes with other computer systems such as journey planners and vehicle real-time tracking systems.

TNDS (Traveline National Dataset)

The Traveline National Dataset (TNDS) contains public transport timetables for bus, light rail, tram and ferry services in Great Britain. It does not include national rail or coach services.

It is managed by Traveline Information Ltd (TIL) who work with local authorities to bring all public transport timetables into a single dataset.

The dataset provides the basis for public transport information in popular apps like Google Maps.

Staging environment

A staging environment is a copy of your production environment (your current live website or app) on a private server. This is a safe place that will allow you to test any changes – major or minor – that you plan on implementing in a secure environment preventing any unexpected errors on your live website or app. 

TLS (Transport Layer Security – formerly SSL)

The standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. TLS is an industry standard and replaced SSL (Secure Sockets Layer) in 1999. SSL (now considered insecure) is still in use as a general term.

SIRI (Service Interface for Real Time Information)

In order to make real-time transport information compatible between different systems, several European countries joined efforts to create a standard protocol known as Service Interface for Real Time Information (SIRI). This protocol describes (at length!) how different systems can share real-time passenger information, allowing different suppliers, operators and local authorities to work together without costly development bills every time one of the party is swapped out.

SERP (Search Engine Results Page)

The list of web pages served to users when they look for something online using a search engine, such as Google. The user enters their search query (using specific terms or phrases known as keywords), upon which the search engine presents them with a SERP.

RTPI (Real Time Passenger Information)

Provides you with information about public transport services in ‘real time’. This allows you to see which services are due to arrive at stops and what time they are expected.

PSP (Payment Service Provider)

Offers retailers online services for accepting electronic payments by a variety of methods including credit card, bank-based payments such as direct debit, bank transfer, and real-time bank transfer based on online banking.
