# Defining tasks with `#[task]`
Tasks, defined with `#[task]`, are the main mechanism of getting work done in RTIC.
Tasks can
-* Be spawned (now or in the future, also by themselves)
-* Receive messages (passing messages between tasks)
-* Be prioritized, allowing preemptive multitasking

* Optionally bind to a hardware interrupt
-RTIC makes a distinction between “software tasks” and “hardware tasks”.

-*Hardware tasks* are tasks that are bound to a specific interrupt vector in the MCU while software tasks are not.

-This means that if a hardware task is bound to, lets say, a UART RX interrupt, the task will be run every
-time that interrupt triggers, usually when a character is received.
+RTIC makes a distinction between “software tasks” and “hardware tasks”. Hardware tasks are tasks that are bound to a specific interrupt vector in the MCU while software tasks are not.
-*Software tasks* are explicitly spawned in a task, either immediately or using the Monotonic timer mechanism.
+This means that if a hardware task is bound to an UART RX interrupt the task will run every time this interrupt triggers, usually when a character is received.
In the coming pages we will explore both tasks and the different options available.
