What is an input component?
The input components would consist of digital devices such as, switches, push buttons, pressure mats, float switches, keypads, radio receivers etc.
The most obvious choice then for the microcontroller is how many digital inputs, analogue inputs and outputs does the system require..
What is an output component?
The visually larger Input and Output components represent service’s HTTP request and response. You should place your service logic in between the two components. Input and Output are two special components of Data Service REST job. … The Input component provides you with a stream of input data.

ngModel is a directive which binds input, select and textarea, and stores the required user value in a variable and we can use that variable whenever we require that value. It also is used during validations in a form.
What is EventEmitter in angular?
EventEmitter is an angular2 abstraction and its only purpose is to emit events in components. Quoting a comment from Rob Wormald. […] EventEmitter is really an Angular abstraction, and should be used pretty much only for emitting custom Events in components. Otherwise, just use Rx as if it was any other library.
What are the 2 types of input devices?

What is the use of @input and output?
They are a mechanism to send/receive data from one component to another. Input is used to receive data in whereas Output is used to send data out. Output sends data out by exposing event producers, usually EventEmitter objects. by the way, I will produce and send data out via the onChange property.
Is hard disk input or output?
Floppy and hard disk drives are both input and output devices because the CPU can either read data from them or write data to them. A CDROM drive, on the other hand, is an input device only because it cannot be written to by the CPU.
What is input () in angular?
A common pattern in Angular is sharing data between a parent component and one or more child components. … @Input() allows a parent component to update data in the child component.
What is the primary output device?

What is @ViewChild in angular?
A ViewChild is a component, directive, or element as a part of a template. If we want to access a child component, directive, DOM element inside the parent component, we use the decorator @ViewChild() in Angular. To understand this, suppose we have two components, a child and a parent one.
