Question 1

Explain Indexing

Answer 1

2. They follow internal and external links in and out of web pages
3. They also read metadata inside web pages to pull out keywords and other data that can be used to help find and index the webpage
4. All this information gets stored in the index of a search engine.
   5.This index needs to be constantly updated so broken links are removed and new web pages are added.
   6.When you carry out a search in a search engine, it is the index that is searched, not the world wide web.
   7.The information in the index can be searched quickly and returns your results list.

Question 3

What does Client Side Mean?

Answer 3

In web development, ‘client side’ refers to everything in a web application that is displayed or takes place on the client (end user device). This includes what the user sees, such as text, images, and the rest of the UI, along with any actions that an application performs within the user’s browser.

Question 4

What does Sever Side Mean?

Answer 4

Sever Side means everything that happens on the server, instead of on the client. In the past, nearly all business logic ran on the server side, and this included rendering dynamic webpages, interacting with databases, identity authentication, and push notifications.
