Init() function in ColdFusion

init() is just a standard convention most people adopt with components. The init() function initializes any variables needed by the component's functions. Then returns a reference to the current component.
ie
    

  1. Test.cfm
    2. 

  2. <cfset myObj = createObject("component", "MyComponent").init(dsn="My DSN")>
    3. 

    4. 

  4. MyComponent.cfc
    5. 

  5. <cfcomponent>
    6. 

  6.     <cffunction name="init" output="false" returntype="MyComponent">
    7. 

  7.          <cfargument name="dsn" type="string">
    8. 

  8.          <!--- initialize variables used within this component --->
    9. 

  9.          <cfset variables.dsn = arguments.dsn>
    10. 

  10.          <!--- return a reference to this component --->
    11. 

  11.          <cfreturn this>
    12. 

  12.     </cffunction>
    13. 

  13. </cfcomponent
    14.

What is the difference between asynchronous and synchronous execution?

When you execute something synchronously, you wait for it to finish before moving on to another task. When you execute something asynchronously, you can move on to another task before it finishes. That being said, in the context of computers this translates into executing a process or task on another "thread." A thread is a series of commands (a block of code) that exists as a unit of work. The operating system can manage multiple threads and assign a thread a piece ("slice") of processor time before switching to another thread to give it a turn to do some work. At its core (pardon the pun), a processor can simply execute a command, it has no concept of doing two things at one time. The operating system simulates this by allocating slices of time to different threads. Now, if you introduce multiple cores/processors into the mix, then things CAN actually happen at the same time. The operating system can allocate time to one thread on the first processor, then a...
