A client is a resource or service requester that makes a request
to a server to obtain a resource or have a service performed.
A server is a resource or service provider that either provides a
requested resource to a client or performs a requested service for the client.
HTTP , or the Hypertext Transfer Protocol, is the set of communication
rules that defines how web browsers and webservers interact on the Internet.
Uniform Resource Locators, or URLs , are used on the Internet to specify
the location of a desired resource along with the means of retrieving it.
PHP is a server-side scripting language that gives a webserver the ability
to run executable code each time a web client requests a particular resource.
PHP executable code can be intermingled with HTML markup.
