Hi! I have been posted content of ccna1 final exam (latest and only question.) I will post the answer and insert image on sunday. If you care, please subscribe your email an become a first person have full test content. Subcribe now Some question have not content because this question have images content. So that can you wait for me? SUNDAY 1. A user sees the command prompt: Router(config-if)# . What task can be performed at this mode? Reload the device. Perform basic tests. Configure individual interfaces. Configure individual terminal lines. 2. Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured with the source MAC address 0050.7320.D632 and the destination MAC address 0030.8517.44C4. The packet inside the captured frame has an IP source address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured? leaving host A leaving ATL leaving...
You can use the setTimeout or setInterval functions.
ReplyDeleteIf you are looking to block the execution of code with call to 'sleep', then no, there is no method for that in JavaScript.
ReplyDeleteJavaScript does have setTimeout method. setTimeout will let you defer execution of a function for x milliseconds. E.g.
setTimeout(myFunction, 3000);// if you have defined a function named myFunction it will run after 3 seconds (3000 milliseconds)
Remember, this is completely different from how 'sleep' method, if it existed, would behave.
function test1()
{
//some code
//Let's say JS did have a sleep function.
sleep(3000); //sleep for 3 seconds,
alert('hi');
}
If you run the above function, you will have to wait for 3 seconds (sleep method call is blocking) before you see the alert 'hi'. Unfortunately, there is no sleep function like that in JavaScript.
function test2()
{
setTimeout(function() { alert('hello');}, 3000); //defer the execution of anonymous function for 3 seconds and go to next line of code.
alert('hi');
}
If you run test2, you will see 'hi' right away (setTimeout is non blocking) and after 3 seconds you will see the alert 'hello'.
f you run the above function, you will have to wait for 3 seconds (sleep method call is blocking)

doSomethingElse();
