The set of input values is called the domain, and the set of output values is called the range. This set contains five ordered pairs, each with an x-coordinate of 5 and different y-coordinates as outputs. This is not a function, since a function requires each input to have only one output. In another set of ordered pairs, (3, −1),(5, −2),(3, −3),(−3, 5), one of the inputs, 3, can produce two different outputs, −1 and −3. You know what that means—this set of ordered pairs is not a function.
GDP (gross domestic product) is the most popular measure of national output. The main challenge in using this method is how to avoid counting the same product more than once. Output is the result of an economic process that has used inputs to produce a product or service that is available for sale or use somewhere else. An input/output device can receive data from users, or another device (input), and send data to another device (output).
A function is a specific type of relation in which each input value has one and only one output value. An input is the independent value, and the output value is the dependent value, as it depends on the value of the input. All of these aspects of a system play an important role.
In turn, each senator can be matched with one specific state that he or she represents. The computer processes the input and then sends a new signal to the output device (e.g. the monitor and speakers). In fact, the computer will still consume all the resources and process the data required to run the video regardless of the presence of the output device (the monitor).
Let’s look back at our examples to determine whether the relations are functions or not and under what circumstances. Remember that a relation is a function if there is only one output for each input. The first value of a relation is an input value and the second value is the output value.
The set of input values is called the domain of the function. And the set of output values is called the range of the function. By definition, the inputs in a function have only one output. Relations are simply correspondences between sets of values or information.
A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs.
What is output example?
Output is defined as the act of producing something, the amount of something that is produced or the process in which something is delivered. An example of output is the electricity produced by a power plant. An example of output is producing 1,000 cases of a product.
Typical examples of output devices are monitors and projectors (video), headphones and speakers (audio), or printers and plotters (physical reproduction in the form of text or graphics). Usually, most output peripherals are meant for human use, so they receive the processed data from the computer and transform it in the form of audio, video, or physical reproductions. It is national output that makes a country rich, not large amounts of money.
- By examining the inputs (x-coordinates) and outputs (y-coordinates), you can determine whether or not the relation is a function.
- Relations can be written as ordered pairs of numbers or as numbers in a table of values.
One interesting component of the conceptual idea of output also is that it may come from the result of input to a successor process. Output can come in a multitude of formats from written long form reports, written short form reports, other verbal means of output. Output may also be a formalized type of material or it can be inform and in some cases discretionary and or informational only.
The following are common examples of process requirements. When we know an output value and want to determine the input values that would produce that output value, we set the output equal to the function’s formula and solve for the input. Solving can produce more than one solution because different input values can produce the same output value. There is a name for the set of input values and another name for the set of output values for a function.
The pairing of each member of your family and their age is a relation. Each family member can be paired with an age in the set of ages of your family members. Another example of a relation is the pairing of a state with its United States’ senators. Each state can be matched with two individuals who have been elected to serve as senator.
Requirements for integration between processes, systems and data repositories. For example, a specification of how data will be mapped from a sales system to a billing system. Process requirements are documented expectations, targets and specifications for business processes. They may be collected from multiple groups of stakeholders such as business units, customers, internal customers, users and subject matter experts.
output – Computer Definition
For example, as you can see in the top half of the image, a keyboard sends electrical signals, which are received by the computer as input. Those signals are then interpreted by the computer and displayed, or output, on the monitor as text or images. In the lower half of the image, the computer sends, or outputs, data to a printer, which will print the data onto a piece of paper, also considered output. The sum total of the deliverables as well as other unique post project outlays are referred to by the project management term output.
Relations can be written as ordered pairs of numbers or as numbers in a table of values. By examining the inputs (x-coordinates) and outputs (y-coordinates), you can determine whether or not the relation is a function. Remember, in a function each input has only one output. Input-output analysis is “a technique used in economics for tracing resources and products within an economy. The system of producers and consumers is divided into different branches, which are defined in terms of the resources they require as inputs and what they produce as outputs.
Examples of input/output devices include the following. Monitor – Receives data from a computer (output) and displays that information as text and images for users to view. It cannot accept data from a user and send that data to another device.
A system may be required to present the user with a display of the number of records in a database. How current this number needs to be, is a non-functional requirement.
For example, an information security subject matter expert may contribute security requirements for a process. In real life and in Algebra, different variables are often linked. When a change in value of one variable causes a change in the value of another variable, their interaction is called a relation.
An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device. A display device is the most common form of output device. The output appears temporarily on the screen and can easily altered or erased, it is sometimes referred to as soft copy also. The display device for a desktop PC is called monitor.
The plan for implementing non-functional requirements is detailed in the system architecture, because they are usually architecturally significant requirements. Non-functional requirements is a catch-all term for requirements that don’t relate to functions and features.
They are contrasted with functional requirements that define specific behavior or functions. The plan for implementing functional requirements is detailed in the system design.
