robots.txt: It is a notepad file in which we write commands to instruct web crawler to not visit the link or webpage which we do not want it to.

Spider: It is a crawler of the search engine which visits, crawls, indexes and saves the website in its database. It also gives ranks to the website which has good content and quality back-links.

They are just different names for the same thing. "Spiders" are "Crawlers" and "Robots" is a word commonly used when talking of robot text which is where you put exclusions for the spiders not to find.

Spider are called google bot or crawlers. They are the agents of google that collect the data and help in indexing the data in google data base.

Robots.txt is a file which is used to restrict the permission on access of data for crawlers. If you dont want to crawl the data of your webpage or any specific section of your website then you can block the access of that section for google bot/crawlers by using robots.txt file.
