What is difference between Asynchronous vs synchronous execution?

Comment

Asynchronous:

In Asynchronous, will not wait to finish first task or response, 
it will jump to another my by before finish, once the task get finish 
simply it will report.
Asynchronous handle more then one task one at a time (Asynchronous work with 2 hands at a time).
Ajax is best example here.

Synchronous: 
In Synchronous, will not take task until finish first.
"No, I'm waiting right here until you finish." This is synchronous.

Synchronous handle task one at a time (Synchronous work with 1 hand at a time).

==========================
  
  
// Example 1 - Synchronous will blocks the task
var result = database.query("SELECT * FROM employee");
console.log("Query finished");
console.log("Next line");


// Example 2 - Asynchronous doesn't block the task 
database.query("SELECT * FROM employee", function(result) {
    console.log("Query finished");
});
console.log("Next line");

Synchronous tasks happen in order—you must complete the current task before moving on to the next. 
Asynchronous tasks are executed in any order or even at once.

Comment

Asynchronous is a non-blocking architecture, so the execution of one task isn't dependent on another. Tasks can run simultaneously. Synchronous is a blocking architecture, so the execution of each operation depends on completing the one before it.
