I’m planning to use jquery frequently in my web pages. If my knowledge is correct , the file size of jquery is roughly 200K.Does the size imply that 200K bytes are downloaded for each my web page?
Thank you in advance.

No; if each of your pages links to jQuery using the same URL, it’ll be downloaded just once, and the browser will reuse the cached copy.
Note that many web sites link directly to the published copy of jQuery at Google; saves everybody bandwidth, as the browser can then share one copy across multiple sites! The URL is, e.g., https://ajax.googleapis.com/ajax/libs/jquery/1.2.3/jquery.min.js .
