The Ignition Gateway is a service that runs in the background of your server's operating system. When running, it is accessed from a web browser. Any computer on the same network can access the Gateway, depending on the Gateway security settings, by using the IP Address or Host Name of the computer where Ignition is installed.
The Gateway Control Utility (GCU) is a lightweight standalone application which provides information about the Gateway. It also provides some basic functionality such as starting and stopping the Gateway, opening the Gateway webpage, performing a Gateway Backup and Restore, resetting the Gateway password, and more.
The Gateway Webpage (or Gateway Web Interface) is a series of pages hosted on Ignition's web server, and is the hub for accessing all functions of the Gateway server. It is where you setup licensing, Gateway configuration settings, database connection, devices connections, modules, projects, security, and more. When the Gateway server is running, you can connect to a device, connect to a database, launch the Designer, and launch a client. You can also check the status of your local Ignition system, agents, sessions, tasks, reports, alarms, and more.

A Graphical User Interface (GUI) (pronounced "gooey") enables a user to interact with a software application through graphics instead of text. The runtime (client) of Ignition is sometimes referred to as the GUI.
In scripting, "The GUI Thread" is referring to the processing power being used to draw the tables, buttons, displays, and everything else on a client. By default most event scripting is run here, but for special tasks there are ways to move the heavy work to a different area.
