Personal Infrastructure
Personal infrastructure is the fundamental tools, services and systems serving an individual that are necessary for that individual's function. For example, if a person has built up a great personal infrastructure, say, having a cell phone, he/she would be able to make long-distance calls. A person that has learned how to drive and has a driver license would be able to use this to travel more effectively to work. Some aspects of personal infrastructure can take years to build up, such as education, programming skills and management skills. On the other hand, some aspects of personal infrastructure will take a comparatively shorter amount of time. For example, a cell phone can be bought quickly. To a certain extent, a home is also an aspect of personal infrastructure. Homeless people cannot perform many daily functions due to lack of a strong and solid personal infrastructure. For example, a home with a washing machine would be easier than a home that has no washing ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell Phone
A mobile phone or cell phone is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones ( landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. These include text messaging, multimedia messaging, email, and internet access (via LTE, 5G NR or Wi-Fi), as well as short-range wireless technologies like Bluetooth, infrared, and ultra-wideband (UWB). Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recording, and g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driver License
A driver's license, driving licence, or driving permit is a legal authorization, or the official document confirming such an authorization, for a specific individual to operate one or more types of motorized vehicles—such as motorcycles, cars, trucks, or buses—on a public road. Such licenses are often plastic and the size of a credit card. In most international agreements, the wording "driving permit" is used, for instance in the Vienna Convention on Road Traffic. In American English, the terms "driver license" or "driver's license" are used. In Australian English, Canadian English and New Zealand English, the terms "driver licence" or "driver's licence" are used while in British English the term is "driving licence". In some countries the term "driving license" is used. The laws relating to the licensing of drivers vary between jurisdictions. In some jurisdictions, a permit is issued after the recipient has passed a driving test, while in others a person acquires their p ...

Education
Education is the transmission of knowledge and skills and the development of character traits. Formal education occurs within a structured institutional framework, such as public schools, following a curriculum. Non-formal education also follows a structured approach but occurs outside the formal schooling system, while informal education involves unstructured learning through daily experiences. Formal and non-formal education are categorized into levels, including early childhood education, primary education, secondary education, and tertiary education. Other classifications focus on teaching methods, such as teacher-centered and student-centered education, and on subjects, such as science education, language education, and physical education. Additionally, the term "education" can denote the mental states and qualities of educated individuals and the academic field studying educational phenomena. The precise definition of education is disputed, and there are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematical Programming
Mathematical optimization (alternatively spelled ''optimisation'') or mathematical programming is the selection of a best element, with regard to some criteria, from some set of available alternatives. It is generally divided into two subfields: discrete optimization and continuous optimization. Optimization problems arise in all quantitative disciplines from computer science and engineering to operations research and economics, and the development of solution methods has been of interest in mathematics for centuries. In the more general approach, an optimization problem consists of maximizing or minimizing a real function by systematically choosing input values from within an allowed set and computing the value of the function. The generalization of optimization theory and techniques to other formulations constitutes a large area of applied mathematics. Optimization problems Optimization problems can be divided into two categories, depending on whether the variables ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Homeless
Homelessness, also known as houselessness or being unhoused or unsheltered, is the condition of lacking stable, safe, and functional housing. It includes living on the streets, moving between temporary accommodation with family or friends, living in boarding houses with no security of tenure, and Internally displaced person, people who leave their homes because of civil conflict and are refugees within their country. The legal status of homeless people varies from place to place. Homeless enumeration studies conducted by the Federal government of the United States, government of the United States also include people who sleep in a public or private place that is not designed for use as a regular sleeping accommodation for human beings. Homelessness and poverty are interrelated. There is no standardized method for counting homeless individuals and identifying their needs; consequently, most cities only have estimated figures for their homeless populations. In 2025, approximatel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washing Machine
A washing machine (laundry machine, clothes washer, washer, or simply wash) is a machine designed to laundry, launder clothing. The term is mostly applied to machines that use water. Other ways of doing laundry include dry cleaning (which uses alternative cleaning fluids and is performed by specialist businesses) and ultrasonic cleaning. Modern-day home appliances use electric power to automatically clean clothes. The user adds laundry detergent, which is sold in liquid, powder, or dehydrated sheet form, to the wash water. The machines are also found in commercial laundromats where customers pay-per-use. History Washing by hand Laundering by hand involves soaking, beating, scrubbing, and rinsing dirty textiles. Before indoor plumbing, it was necessary to carry all the water used for washing, boiling, and rinsing the laundry from a pump, Water well, well, or Spring (hydrology), spring. Water for the laundry would be hand-carried, heated on a fire for washing, and then poured i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distribution Of Wealth
The distribution of wealth is a comparison of the wealth of various members or groups in a society. It shows one aspect of economic inequality or heterogeneity in economics, economic heterogeneity. The distribution of wealth differs from the income distribution in that it looks at the Distribution (economics), economic distribution of ownership of the assets in a society, rather than the current income of members of that society. According to the International Association for Research in Income and Wealth, "the world distribution of wealth is much more unequal than that of income." For rankings regarding wealth, see list of countries by wealth equality or list of countries by wealth per adult. Definition of wealth Wealth of an individual is defined as net worth, expressed as: wealth = assets − liability (financial accounting), liabilities A broader definition of wealth, which is rarely used in the measurement of wealth inequality, also includes human capital.
