 | task driver               | Task drivers are used by nomad clients to execute a task and provide resource isolation.                                                                                                                                                                                          |

 | job_specification/jobspec | A job specification, also known as a jobspec defines the schema for nomad jobs. This describes the type of the job, the tasks and resources necessary for the job to run, job information like which clients it can run on, or more.                                              |
 | allocation                | An allocation is a mapping between a task group in a job and a client node. When a job is run, Nomad will chose a client capable of running it and allocates resources on the machine for the ask(s) in the task group defined for the job.                                       |
 | workload artifact         | The runnable blob to be scheduled on a task driver. Examples include docker images, raw binaries, java applications, and VMs using QEMU.                                                                                                                                          |
