Since a year and a half I am trying to figure out how some websites update their content in real time without AJAX method.
Please see this example website: https://pro.btcturk.com/en/basic/exchange/BTC_TRY
That website is changing many texts within content in different timing.
It means that when the server is updated with new values in the database then the website is listening to database changes and then reflecting/delivering inside content without ajax calls.
Can someone give an example how to achieve such functionality possibly using Javascript or PHP normal hand-code appreciated?
Thank you
You can see the process here:

I have created a simple project with two HTML page 'home' and 'details'. I have a spreadsheet of some data I want to show as list in 'home' page and on clicking shows associated details. I tried searching in internet but I was left with even more question than before. The data consist of 10 column and 1000 rows and might reach 5000 rows.
If you are facing trouble while learning DataBase, there is an alternative you can try and it is very easy to understand and implement in your code.
You can learn about JSON (JavaScript Object Notation), Simply you have to create a JSON file in which you can store the detail of all those 1000-5000 rows and render them on your Web page using JavaScript

You can try to work with long polling or comet or web socket features for auto-updating your chat system, while you want to check the user, starts typing or no.

I am using infinite scroll and would like to post an image after every 3 times an article is loaded. Preferably a WordPress function would be best. Can anyone direct me to an article which covers this or perhaps offer a solution.
If I understood your problem, a good solution is AJAX.
Once an article is loaded, call a JS function which call your Wordpress function.
I am not a Wordpress expert but AJAX is an hint to achieve that.

I have built an Admin section where i can see all the contents from database in a table. everything is fine but if the database table has thousands of rows I have to scroll down very deep. is there any way I can make links like `1,2,3.Next the way google search results do? or is there any even better way?
Isn't is going to be something like:
if($(document).height>2000){
//what should i do?
}
Looks like you are using jquery. If you are going to implement everything on your own it may be time consuming - although it would be fun!
To save some time, there are quite a few plugins available to achieve this. Refer:
https://datatables.net/
http://www.jqueryscript.net/table/Client-side-HTML-Table-Pagination-Plugin-with-jQuery-Paging.html
Since you may have huge data you should be using server side pagination instead of client side. Here is another SO link which explains the difference between them : Pagination: Server Side or Client Side?

I have created a webpage that takes a skill survey of students of a particular college but they are not ready to give me server yet they would want to see the prototype first how to show them the prototype without using the server but just using the web page that I have created?
A prototype shows how it works without actually working. So instead of getting real data, it can show fake data.
Your survey can show just two or three questions, and these questions can be hard-coded or loaded from a mock object, instead of loaded from the server. Also, instead of actually saving anything, it can just jump to the next question and show a text saying 'Thanks' when you are done.
That way, you can see if your survey has the right look and feel, and they can see that too. Also, it may make it a bit more clear to the server-builders what kind of implementation they need to make. A visible, 'clickable' prototype makes it easier to discuss details in the implementation.
