= Component: Computer =

Computers provide a couple of API callbacks. Note that these can only be called by the computer itself, or its direct neighbors (i.e. other computers that share a face with that computer). Also note that since robots cannot interact with external components they cannot start/stop/query computers, but computers can interact with robots sitting next to them.

Component name: `computer`. Callbacks:

* `start(): boolean`

<pre>Tries to start the computer. Returns `true` on success, `false` otherwise. Note that this will also return `false` if the computer was already running. If the computer is currently shutting down, this will cause the computer to reboot instead.
</pre>
* `stop(): boolean`

<pre>Tries to stop the computer. Returns `true` on success, `false` otherwise. Also returns `false` if the computer is already stopped.
</pre>
* `isRunning(): boolean`

<pre>Returns whether the computer is currently running.
</pre>
* `beep([frequency:number[, duration:number]])`

<pre>Plays a tone, useful to alert users via audible feedback. Supports frequencies from 20 to 2000Hz, with a duration of up to 5 seconds.
</pre>
* `getDeviceInfo(): table`

<pre>Returns a table of device information. Note that this is architecture-specific and some may not implement it at all.
</pre>
* `crash(reason: string)`

<pre>Attempts to crash the computer for the specified reason.
</pre>
* `getArchitecture(): string`

<pre>Returns the computer's current architecture.
</pre>
* `isRobot(): boolean`

<pre>Returns whether or not the computer is, in fact, a robot.
</pre>
== Example use: ```lua local component = require("component") local c = component.computer -- get primary computer, e.g. self print(c.isRunning()) -- definitely true if it's this computer c.stop() -- basically like computer.shutdown() if it's this computer ``` ==
