Secondary education normally takes place in secondary schools, taking place after primary education and may be followed by higher education or vocational training. In some countries, only primary or basic education is compulsory, but secondary education is included in compulsory education in most countries.

A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet. Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server.

Shareware is a type of proprietary software which is initially provided free of charge to users, who are allowed and encouraged to make and share copies of the program. Shareware is often offered as a download from a website or on a compact disc included with a magazine. Shareware differs from open-source software, in which the source code is available for anyone to inspect and alter; and freeware, which is software distributed at no cost to the user but without source code being made available. There are many types of shareware, and while they may not require an initial up-front payment, many are intended to generate revenue in one way or another. Some limit use to personal non-commercial purposes only, with purchase of a license required for use in a business enterprise. The software itself may be limited in functionality or be time-limited, or it may remind the user that payment would be appreciated.

Shingled magnetic recording (SMR) is a magnetic storage data recording technology used in hard disk drives (HDDs) to increase storage density and overall per-drive storage capacity. Conventional hard disk drives record data by writing non-overlapping magnetic tracks parallel to each other (perpendicular magnetic recording, PMR), while shingled recording writes new tracks that overlap part of the previously written magnetic track, leaving the previous track narrower and allowing for higher track density. Thus, the tracks partially overlap similar to roof shingles. This approach was selected because physical limitations prevent recording magnetic heads from having the same width as reading heads, leaving recording heads wider.

The Smithsonian Institution ( smith-SOH-nee-ən), also known simply as the Smithsonian, is a group of museums and research centers administered by the government of the United States. It was founded on August 10, 1846, 'for the increase and diffusion of knowledge'. The institution is named after its founding donor, British scientist James Smithson.

Sojourner Truth (; born Isabella [Belle] Baumfree; c. 1797 – November 26, 1883) was an African-American abolitionist and women's rights activist. Truth was born into slavery in Swartekill, Ulster County, New York, but escaped with her infant daughter to freedom in 1826. After going to court to recover her son in 1828, she became the first black woman to win such a case against a white man.

She gave herself the name Sojourner Truth in 1843 after she became convinced that God had called her to leave the city and go into the countryside 'testifying the hope that was in her'. Her best-known speech was delivered extemporaneously, in 1851, at the Ohio Women's Rights Convention in Akron, Ohio. The speech became widely known during the Civil War by the title 'Ain't I a Woman?,' a variation of the original speech re-written by someone else using a stereotypical Southern dialect, whereas Sojourner Truth was from New York and grew up speaking Dutch as her first language. During the Civil War, Truth helped recruit black troops for the Union Army; after the war, she tried unsuccessfully to secure land grants from the federal government for former slaves (summarized as the promise of 'forty acres and a mule'). In 2014, Truth was included in Smithsonian magazine's list of the '100 Most Significant Americans of All Time'.

Stands for 'Secure Sockets Layer.' SSL is a secure protocol developed for sending information securely over the Internet. Many websites use SSL for secure areas of their sites, such as user account pages and online checkout. Usually, when you are asked to 'log in' on a website, the resulting page is secured by SSL.

An SSL certificate, or secure certificate, is a file installed on a secure Web server that identifies a website. This digital certificate establishes the identity and authenticity of the company or merchant so that online shoppers can trust that the website is secure and reliable. In order to verify that these sites are legitimate (they are who they say they are), the companies and their websites are verified by a third party, such as Verisign or Thawte.

Stigma or plural stigmata, stigmas may refer to: Social stigma, the disapproval of a person based on physical or behavioral characteristics that distinguish them from others

A computer storage device is any type of hardware that stores data. The most common type of storage device, which nearly all computers have, is a hard drive. The computer's primary hard drive stores the operating system, applications, and files and folders for users of the computer.

The Student Nonviolent Coordinating Committee (SNCC, often pronounced SNIK) was the principal channel of student commitment in the United States to the Civil Rights Movement during the 1960s.

Emerging in 1960 from the student-led sit-ins at segregated lunch counters in Greensboro, North Carolina and Nashville, Tennessee, the Committee sought to coordinate and assist direct-action challenges to the civic segregation and political exclusion of African-Americans. From 1962, with the support of the Voter Education Project, SNCC committed to the registration and mobilization of black voters in the Deep South.

Women's suffrage is the right of women to vote in elections. Beginning in the late 19th century, besides women working for broad-based economic and political equality and for social reforms, women sought to change voting laws to allow them to vote. National and international organizations formed to coordinate efforts towards that objective, especially the International Woman Suffrage Alliance (founded in 1904 in Berlin, Germany), as well as for equal civil rights for women.

Sunni Islam is the largest branch of Islam; and makes up more than half of the Muslims in the world.
