Computer science

Two common ways to collect data is via conducting interviews or surveys.  Interviews provide a free form of the answers to provided questions. Such data is not easily consumed by computers. Surveys have a rating system associated with questions, or true and false choices. The data from surveys can easily be consumed by a computer. Surveys have a problem over interviews, that it is impossible to get a response from the user, that does not fit the given options.

A good example of the output data that can easily be consumed is a chart. A chart will show low and high point, and a change over a specific change of one variable.

Input data is the data that is entered into a computer, output data is the data that comes out of a computer or final result, after the processing of the input data is done. For example for a self driving car the input can be a presence of obstacles, the output will be decision if it is safe to drive or not.

Data is a set of numbers, that don't have a particular meaning, information is making sense of that data. For example 20-25 feet is the example data, but if the same is tied to height of the building this data becomes the information. For example, if someone says that the average height of a two story building is 20-25 feet, it is already the information.

​It is important to keep in mind what users actually want when developing a program. There a couple of term that can describe a program. First term is usability. Usability is a description of how well that code is useable by other people. Accessibility defines what is needed to use that code.

​Readme file describes of how a program can be used, and describes it’s program functionality.
