Answer:
The first thing that the browser checks is the cache for the DNS record to find the corresponding IP address.
Explanation:
After the technician sets up the internal DNS server for his local network, the first thing that is checked when he types a website into the url of a browser is the cache to look for corresponding IP addresses.
DNS which means Domain Name System is a database that maintains the website name (URL) and the IP address that it is linked to. There is a unique IP address for every URL (universal resource locator).
Internal DNS servers store names and IP addresses for internal or private servers
Answer:
- function processNumbers(numList){
- try{
- for(let i=0; i < numList.length; i++){
- if(isNaN(numList[i])){
- throw "All elements in the list should be numbers.";
- }
-
- }
- }
- catch(err){
- console.log(err);
- }
- }
-
- let myList = [4, 6, 1, "abc", 9];
- processNumbers(myList);
Explanation:
The solution code is written in JavaScript as the isNaN() is an in-built function in JavaScript.
Firstly, create a function processNumbers that takes one input number list, numList (Line 1).
To handle the possible Not a Number (NaN) error, create a try and catch block. In the try block, create a for-loop to traverse through the numList array and use isNaN function to check if the current value is a number (Line 3 - 4). If it is not a number, isNaN will return true and the program will run the throw statement (Line 5). The throw message will be passed to the catch block and display it on console (Line 10 - 12).
We can test the function by using the sample list (Line 15 - 16) and we shall see the thrown error message is displayed.
