What's the difference between a browser and a server?

[Elgo]

A browser, typically an internet browser, is any piece of software that is used to connect to websites and generally browse the internet. The default browser for Windows is Internet Explorer and the default browser for OS X is Safari. Other popular options for browsers are Google Chrome and Mozilla Firefox. There are also things called file browsers, which is what Windows uses whenever you look for a document in My Documents. This is called Windows Explorer.
A server is any computer that is being used as a central source for connections. Your computer, the client, sends a request to the central computer, the server, and then the server processes it and send back a result. This can be like sending for a page to print, downloading a file or even just viewing a website.
