Maggie Lena Walker (July 15, 1864 – December 15, 1934) was an African-American teacher and businesswoman. Walker was the first African American woman to charter a bank and serve as its president in the United States. As a leader, she achieved successes with the vision to make tangible improvements in the way of life for African Americans and women. Disabled by paralysis and limited to a wheelchair later in life, Walker also became an example for people with disabilities. Walker's restored and furnished home in the historic Jackson Ward neighborhood of Richmond, Virginia has been designated a National Historic Site, operated by the National Park Service.

Medicaid in the United States is a federal and state program that helps with medical costs for some people with limited income and resources. Medicaid also offers benefits not normally covered by Medicare, including nursing home care and personal care services. The Health Insurance Association of America describes Medicaid as 'a government insurance program for persons of all ages whose income and resources are insufficient to pay for health care.' Medicaid is the largest source of funding for medical and health-related services for people with low income in the United States, providing free health insurance to 74 million low-income and disabled people (23% of Americans) as of 2017. It is a means-tested program that is jointly funded by the state and federal governments and managed by the states, with each state currently having broad leeway to determine who is eligible for its implementation of the program. States are not required to participate in the program, although all have since 1982. Medicaid recipients must be U.S. citizens or qualified non-citizens, and may include low-income adults, their children, and people with certain disabilities. Poverty alone does not necessarily qualify someone for Medicaid. The Patient Protection and Affordable Care Act (PPACA) significantly expanded both eligibility for and federal funding of Medicaid. Under the law as written, all U.S. citizens and qualified non-citizens with income up to 133% of the poverty line, including adults without dependent children, would qualify for coverage in any state that participated in the Medicaid program. However, the Supreme Court of the United States ruled in National Federation of Independent Business v. Sebelius that states do not have to agree to this expansion in order to continue to receive previously established levels of Medicaid funding, and many states have chosen to continue with pre-ACA funding levels and eligibility standards.Research suggests that Medicaid improves recipients' financial security. However, the evidence is mixed regarding whether Medicaid actually improves health outcomes, although 'the best existing evidence says [having health insurance] improves health'.Medicaid and Medicare are the two government sponsored medical insurance programs in the United States and are administered by the U.S. Centers for Medicare & Medicaid Services in Baltimore, Maryland.

Stands for 'MPEG-1 Audio Layer-3.' MP3 is popular compressed audio file format that helped popularize digital music downloads beginning in the late 1990s. MP3 files are typically about one tenth the size of uncompressed WAVE or AIFF files, but maintain nearly the same CD-quality sound. Because of their small size and good fidelity, MP3 files have become a popular way to store music files on both computers and portable devices like the iPod.

Stands for 'Moving Picture Experts Group.' The term MPEG refers to a type of multimedia file, which is denoted by the file extension '.mpg' or '.mpeg.' These files are compressed movies that can contain both audio and video. Though they are compressed, MPEG files maintain most of the original quality of the uncompressed movie. This is why many videos on the Web, such as movie trailers and music videos, are available in the MPEG format.

As the name implies, multimedia is the integration of multiple forms of media. This includes text, graphics, audio, video, etc. For example, a presentation involving audio and video clips would be considered a 'multimedia presentation.' Educational software that involves animations, sound, and text is called 'multimedia software.' CDs and DVDs are often considered to be 'multimedia formats' since they can store a lot of data and most forms of multimedia require a lot of disk space.

Music hall is a type of British theatrical entertainment that was popular from the early Victorian era, beginning around 1850. It ended, arguably, after the First World War, when the halls rebranded their entertainment as variety. Perceptions of a distinction in Britain between bold and scandalous Victorian Music Hall and subsequent, more respectable Variety differ. Music hall involved a mixture of popular songs, comedy, speciality acts, and variety entertainment. The term is derived from a type of theatre or venue in which such entertainment took place. In North America vaudeville was in some ways analogous to British music hall, featuring rousing songs and comic acts.
