Data (computing)
In computing, data (treated as singular, plural, or as a mass noun) is any sequence of one or more symbols. Datum is a single symbol of data. Data requires interpretation to become information. Digital data is data that is represented using the binary number system of ones (1) and zeros (0), as opposed to analog signal, analog representation. In modern (post-1960) computer systems, all data is digital. Data exists in three states: data at rest, data in transit and data in use. Data within a computer, in most cases, Parallel communication, moves as parallel data. Data moving to or from a computer, in most cases, Serial communication, moves as serial data. Data sourced from an analog device, such as a temperature sensor, may be converted to digital using an analog-to-digital converter. Data representing quantities, characters, or symbols on which operations are performed by a computer are data storage device, stored and Record (computer science), recorded on magnetic tape data ...

End User
In product development, an end user (sometimes end-user) is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysop A sysop (; an abbreviation of system operator) is an administrator of a multi-user computer system, such as a bulletin board system A bulletin board system or BBS (also called ''Computer Bulletin Board Service'', ''CBBS'') is a computer server ...s, system administrators, database administrators, information technology experts, software professionals and computer technicians. End users typically do not possess the technical understanding or skill of the product designers, a fact easily overlooked and forgotten by designers: leading to features creating low customer satisfaction. In information technology, end users are not "customer In sales Sales are activities related to selling or the number of goods sold in a given targeted time period. T ...

Scalability
Scalability is the property of a system to handle a growing amount of work by adding resources to the system. In an economic An economy (; ) is an area of the production Production may be: Economics and business * Production (economics) * Production, the act of manufacturing goods * Production, in the outline of industrial organization, the act of making products ... context, a scalable business model implies that a company can increase sales given increased resources. For example, a package delivery system is scalable because more packages can be delivered by adding more delivery vehicles. However, if all packages had to first pass through a single warehouse for sorting, the system would not be as scalable, because one warehouse can handle only a limited number of packages. In computing, scalability is a characteristic of computers, networks, algorithm In and , an algorithm () is a finite sequence of , computer-implementable instructions, typically to solve a ...
