The C102-1.00/M part of Tasker is a task scheduler used to coordinate and manage tasks in computer systems. It is an open source task scheduling tool that provides users with the ability to manage and control workflows within a computer system. It allows users to set up tasks, such as creating documents, launching applications, printing files, or running scripts, and then schedule them to run at certain times or on certain events. The system can also pause and resume tasks, so it can be used for job scheduling, batch processing, and automation.
