Transport Triggered Architecture (TTA) is a way of building computer systems. It's like a pipeline that moves data through different 'stages' or steps. At each step, different parts of the system can do different things with the data. This makes it easier to separate tasks, so that the computer can do more complicated things. For example, a modern computer has many different parts - like the memory, the CPU, and the network - that all need to be able to send and receive data, but they can't all talk to each other directly. With TTA, the data can be sent to each part in turn and it will only do what it's supposed to do with the data. The data then gets sent to the next part, until the task is finished. In this way, the different parts of the system can work together easily and it's easy to build new tasks quickly.
