What is a Hit in Internet

Hit:
A hit is a request to a web server for a file (web page, image, JavaScript, Cascading Style Sheet, etc.). When a web page is uploaded from a server the number of "hits" or "page hits" is equal to the number of files requested. Therefore, one page load does not always equal one hit because often pages are made up of other images and other files which stack up the number of hits counted. Because one page load does not equal one hit it is an inaccurate measure of a website's popularity or web traffic. A more accurate measure of web traffic is how many page views a web site has. Hits are useful when evaluating the requirements of your server, depending on the number and size of files which need to be transferred for one request. Servers should be tested to make sure they meet throughput targets (i.e. they should be capable of processing a certain amount of 'hits' per second).
Unique hits count the number of different individuals who have generated at least one hit.

(1) Also called a page hit. The retrieval of any item, like a page or a graphic, from a Web server. For example, when a visitor calls up a Web page with four graphics, that's five hits, one for the page and four for the graphics. For this reason, hits often aren't a good indication of Web traffic. Compare with page view.
(2) Any time a piece of data matches criteria you set. For example, each of the matches from a Yahoo or any other search engine search is called a hit.
Web Counter/hit counter:
A web counter or hit counter is a computer software program that indicates the number of visitors, or hits, a particular webpage has received. Once set up, these counters will be incremented by one every time the web page is accessed in a web browser.
