I suppose people are downvoting you because this is a very general question without much context about what you really want/need to know. It is the kind of thing someone without any knowledge of computers would ask. – Lordsandladies

Answer 4

The 1st answer (Ramesh Soni's answer) is simple and concise. I also wanna share a useful terms distinction that's relevance to this.

What's the difference between request and query???

• First of all, query and request can both be nouns and verbs. E.g:

  • I requested a refund.
  • We received a request for a refund.
  • I queried the price.
  • We received a query about the price.

• To request something is to ask for something, an object or a favour etc. A request is a polite demand. To query is to ask about something i.e. you are wanting information. A query is a question.

• Also, QUERY is an inquiry(Query and inquiry are synonyms) They are both requests but the difference is that the QUERY is a precise request. In informatics, if you need information about something you need to send a specific request with precise information.

"I queried information about user account Maxim Pavlov" = "I need to know about this website users. In particular, I need to know if there is any Maxim Pavlov registered on this site".

• If you are Arabic, best translations in Arabic would be, request = طلب and query = إستعلام)
