The terminal implements a client-server architecture with the server running on a multiprocessor [[Unix]] platform. The client, used by end users to interact with the system, is a [[Microsoft Windows|Windows]] application that typically connects directly through a router provided by Bloomberg and installed on-site. End users can also make use of an extra service (''Bloomberg Anywhere'') to allow the Windows application to connect via internet/IP, or Web access via a [[Citrix]] client. There are also applications that allow mobile access via [[Android (operating system)|Android]] and [[iOS (Apple)|iOS]]. The server side of the terminal was originally developed using mostly the [[programming language]]s [[Fortran]] and [[C (programming language)|C]]. Recent years have seen a transition towards [[C++]] and embedded [[JavaScript]] on the clients and servers.

Each server machine runs multiple instances of the server process. Using a proprietary form of context-switching, the servers keep track of the state of each end user, allowing consecutive interactions from a single user to be handled by different server processes. The [[graphical user interface]] (GUI) code is also proprietary.
