Answer: Option A
Solution (By Examveda Team)
This question is asking about the relationship between indexes and loading speed in a MySQL table.Let's break it down:
Indexes are like a table of contents for your data. They help MySQL quickly find specific rows in a large table. Think of it like looking for a word in a dictionary.
Loading means adding new data to the table.
Now, if a table has no indexes, MySQL has to scan through all the data every time it needs to find something. It's like looking for a word in a huge novel without any page numbers.
But if the table has indexes, MySQL can use those indexes to jump straight to the right data. This is like using the table of contents in a book to quickly find the page you want.
So, which is faster?
Loading a table without indexes is faster!
Because there's no extra work involved in maintaining and using indexes.
But here's the catch:
Although loading is faster without indexes, searching and retrieving data is much slower.
Think of it this way: Indexes make searching faster but slow down loading.
So, the answer to the question is Option A: True.
