Each component describes the inputs, outputs, and implementation of the\ncomponent. For example, `train_op` is a component in the following code sample.\n\nFor example, a training component could take a CSV file as an input and use it\nto train a model. By setting the machine type parameters on the pipeline step,\nyou can manage the requirements of each step in your pipeline. If you have two\ntraining steps and one step trains on a huge data file and the second step\ntrains on a small data file, you can allocate more memory and CPU to the first\ntask, and fewer resources to the second task.\n\nBy default, the component will run on as a Vertex AI\n[`CustomJob`](/vertex-ai/docs/reference/rest/v1/projects.locations.customJobs)\nusing an **e2-standard-4** machine, with 4 core CPUs and 16GB memory.
