History List
A menu in a web browser which displays recently visited sites. The same mechanism makes it possible for servers to track where a browser was before visiting a particular site.
Hits
Contrary to popular belief, a hit does not represent a single visitor to a website. A hit is actually a request for a single file from your web server. This means one page can actually generate multiple hits, as each page generally has more than one file (an html or other base file, a css file, multiple images, etc.) and each one is requested from the server whenever the page is loaded. Some marketing people like to quote hits to unknowing consumers as the number makes their site sound like it’s getting a whole lot more traffic than it actually is.
HomePage
It is a first page (also referred as an opening page, start page or main page) of a Web site. This would technically be your index page or default page of your directory.
HTML

HTTP
Stands for HyperText Transfer Protocol. HTTP is a set of rules for transferring hypertext requests between a web browser and a web server.
HTTPS
Similar to HTTP, HTTPS stands for HyperText Transfer Protocol over SSL (Secure Socket Layer) or, alternately, HyperText Transfer Protocol Secure. Like HTTP, it’s a set of rules for transferring hypertext requests between browsers and servers, but this time it’s done over a secure, encrypted connection.
