How many input modes are there?
In addition to multiple types of logical input devices, we can obtain the measure of a device in three distinct modes: 1) Request mode, 2) Sample mode, and 3) Event mode.
It defined by the relationship between the measure process and the trigger.
Normally, the initialization of an input device starts a measure process..
What is input data and output data?
An input is data that a computer receives. An output is data that a computer sends. Computers only work with digital information. Any input that a computer receives must be digitised. Often data has to be converted back to an analogue format when it’s output, for example the sound from a computer’s speakers.
What are the modes of data input?
Data is entered directly into the computer one transaction at a time (also known as transaction processing) under program control. The main types of on-line data entry device are: VDUs, teletypes, light pens, voice input and shop-floor data collection devices. They can be used off-line also for bulk data collection.
How does operating system handle input and output?
In other words, an operating system handles input and output devices. Operating systems use device drivers written by hardware creators to communicate with their devices. … The operating system sits in between the applications you run and the hardware, using the hardware drivers as the interface between the two.
What is input with example?

What is main input data?
Whenever you enter data into your computer, it is referred to as input. This can be text typed in a word processing document, keywords entered in a search engine’s search box, or data entered into a spreadsheet. … Devices such as the keyboard, mouse, scanner, and even a digital camera are considered input devices.
What is the difference between data entry and data input?
Data entry is the input and storage of text and numbers from a document into an electronic system. … When data sources include handwriting, it gets trickier to utilize automated processing methods. Handwritten data requires manual data entry which is more expensive and time consuming than automated software.
What is input and output examples?
Examples of input devices include the following. Keyboard and Mouse – Accepts input from a user and sends that data (input) to the computer. They cannot accept or reproduce information (output) from the computer. Microphone – Receives sound generated by an input source, and sends that sound to a computer.
What is input and output of a program?
