PC games, also known as computer games or personal computer games, are video games played on a personal computer rather than a dedicated video game console or arcade machine.

Their defining characteristics include a lack of any centralized controlling authority, a greater degree of user control over the video-gaming hardware and software used and a generally greater capacity in input, processing, and output.

An open-source video game, or simply an open-source game, is a video game whose source code is open-source.

They are often freely distributable and sometimes cross-platform compatible.

Many are included in Linux distributions as a result..

An online game is a video game that is either partially or primarily played through the Internet or another computer network.

Online games are ubiquitous on modern gaming platforms, including PCs, consoles and mobile devices, and span many genres, including first-person shooters, strategy games and massively multiplayer online role-playing games (MMORPG).

In computer networks, to download is to receive data from a remote system, typically a server such as a web server, an FTP server, an email server, or other similar systems.

This contrasts with uploading, where data is sent to a remote server.

Advertising is an audio or visual form of marketing communication that employs an openly sponsored, nonpersonal message to promote or sell a product, service or idea.

Sponsors of advertising are often businesses who wish to promote their products or services.

Advertising is differentiated from public relations in that an advertiser usually pays for and has control over the message.

It is differentiated from personal selling in that the message is nonpersonal, i.e., not directed to a particular individual.
