Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered user of Facebook, though this may vary depending on local laws.

Facebook makes most of its revenue from advertisements that appear onscreen and in users' News Feeds.The Facebook service can be accessed from devices with Internet connectivity, such as personal computers, tablets and smartphones. After registering, users can create a customized profile revealing information about themselves. They can post text, photos and multimedia which is shared with any other users that have agreed to be their "friend".

2003–2006: Thefacebook, Thiel investment, and name change

Zuckerberg built a website called "Facemash" in 2003 while attending Harvard University.

Zuckerberg faced expulsion and was charged with breaching security, violating copyrights and violating individual privacy. Ultimately, the charges were dropped. Zuckerberg expanded on this project that semester by creating a social study tool ahead of an art history final exam. He uploaded all art images to a website, each of which was accompanied by a comments section, then shared the site with his classmates.WEB, Jason, Kincaid, Startup School: An Interview With Mark Zuckerberg,weblink TechCrunch, AOL, October 24, 2009, June 24, 2017, File:Thefacebook.png|thumb|Original layout and name of Thefacebook in 2004, showing actor Al Pacino's face superimposed with binary numbers as Facebook's original logo, designed by co-founder Andrew McCollumNEWS,weblink This Person Was The First Face of Facebook, Shontell, Alyson, May 16, 2011, Business InsiderBusiness InsiderA "face book" is a student directory featuring photos and personal information.

Facebook Ireland is subject to the US GILTI tax of 10.5% on global intangible profits (i.e. Irish profits). On the basis that Facebook Ireland is paying some tax, the effective minimum US tax for Facebook Ireland will be circa 11%. In contrast, Facebook Inc. would incur a special IP tax rate of 13.125% (the FDII rate) if its Irish business relocated to the US. Tax relief in the US (21% vs. Irish at the GILTI rate) and accelerated capital expensing, would make this effective US rate around 12%.WEB,weblink KPMG Report on TCJA, KPMG, February 2018, MAGAZINE,weblink Breaking Down the New U.S. Corporate Tax Law, Harvard Business Review, December 26, 2017, NEWS, US corporations could be saying goodbye to Ireland,weblink Irish Times, January 17, 2018, The insignificance of the US/Irish tax difference was demonstrated when Facebook moved 1.5bn non-EU accounts to the US to limit exposure to GDPR.WEB,weblink Exclusive: Facebook to put 1.5 billion users out of reach of new EU privacy law, April 19, 2018, Reuters News, NEWS,weblink Facebook moves 1.5bn users out of reach of new European privacy law, The Guardian, London, April 19, 2018,

2012 architecture

Facebook is developed as one monolithic application. According to an interview in 2012 with Chuck Rossi, a build engineer at Facebook, Facebook compiles into a 1.5 GB binary blob which is then distributed to the servers using a custom BitTorrent-based release system. Rossi stated that it takes about 15 minutes to build and 15 minutes to release to the servers. The build and release process has zero downtime. Changes to Facebook are rolled out daily.Facebook used a combination platform based on HBase to store data across distributed machines. Using a tailing architecture, events are stored in log files, and the logs are tailed. The system rolls these events up and writes them to storage. The user interface then pulls the data out and displays it to users. Facebook handles requests as AJAX behavior. These requests are written to a log file using Scribe (developed by Facebook).WEB,weblink Facebook's New Real-time Analytics System: HBase To Process 20 Billion Events Per Day,, March 22, 2011, December 26, 2012, Data is read from these log files using Ptail, an internally built tool to aggregate data from multiple Scribe stores. It tails the log files and pulls data out. Ptail data are separated into three streams and sent to clusters in different data centers (Plugin impression, News feed impressions, Actions (plugin + news feed)). Puma is used to manage periods of high data flow (Input/Output or IO). Data is processed in batches to lessen the number of times needed to read and write under high demand periods (A hot article generates many impressions and news feed impressions that cause huge data skews). Batches are taken every 1.5 seconds, limited by memory used when creating a hash table.Data is then output in PHP format. The backend is written in Java. Thrift is used as the messaging format so PHP programs can query Java services. Caching solutions display pages more quickly. The data is then sent to MapReduce servers where it is queried via Hive. This serves as a backup as the data can be recovered from Hive.

Additionally, while Facebook users have the ability to download and inspect the data they provide to the site, data from the user's "shadow profile" is not included, and non-users of Facebook do not have access to this tool regardless. The company has also been unclear whether or not it is possible for a person to revoke Facebook's access to their "shadow profile."
