Computer Input, Processing, Output and Storage Devices
Input: Getting Data from the User to the Computer Keyboard. A keyboard is usually part of a personal computer or part of a terminal that is connected to a computer Mouse. A mouse is an input device with a ball on its underside that is rolled on a flat surface, usually the desk on Trackball. A. Aug 02, · 1. Data entry is the inputting of data or information into a computer using input devices, such as a keyboard, scanner, disk, and voice. 2. Data entry is a job where an employee inputs data into a computer from forms or other non-electronic forms of data.

What computers do: input, process, and output Computers work with inputs, processes and outputs. Watch this video on how to support children to develop their understanding of these. View transcript. Computers ino with inputs, processes, and outputs. An input is data entered into or received by a computer, such as a keypress, mouse click, or sensor reading.
For example, a temperature sensor could gather and input data into a computer, or a message could be wirelessly received by a computer from another device.
A process determines what a computer does with an input, but the same input can be processed in different ways. For example, pressing the A key on your keyboard will display the letter A when using word processing software, or it could be a directional control for moving a character in gaming software. A xata contains the set of instructions that define the process. The output is how the computer presents the results of the process, such as text on a screen, printed materials, or sound from a speaker.
As your pupils develop the understanding of how computers work, you can reflect on the inputs, processes, and outputs of everyday digital adta.
Think about your day. How many times have you used a computer? What were the inputs, processes, and outputs of those devices?

An input is data entered into or received by a computer, such as a keypress, mouse click, or sensor reading. Inputs can give instructions to a computer or provide data to process, but inputs don’t need to be initiated by people. Computer input can simply be defined as the information entered into a computer system including typed text, mouse clicks, etc. Computer Input devices are those responsible for the insertion of data into the computer, that is instructing the computer. They are devices that enter information into a computer from an external source. Aug 29, · In addition to the keys of the main keyboard (used for typing text), keyboards usually also have a numeric keypad (for entering numerical data efficiently), a bank of editing keys (used in text editing operations), and a row of function keys along the top (to easily invoke certain program functions).
Understanding the classification of computer input, processing, output, and storage devices in accordance with their function helps students or computer users clearly distinguish between the various components of the computer system.
Computers devices are components that help to make the computer system interacts within itself and its environment.
A computer system refers to the computer itself and all other components associate with the functionalities of the computer including human beings operating the computer. Computer devices include input, output, processing, and storage. Computer input can simply be defined as the information entered into a computer system including typed text, mouse clicks, etc.
Computer Input devices are those responsible for the insertion of data into the computer, that is instructing the computer. They are devices that enter information into a computer from an external source.
Computer Processing is the means by which computer programs and instructions are being executed. It is actually the process of transforming input data into output information.
Computer Processing devices are those devices directly responsible for the transformation of data into information. The processor is the main component in the System unit capable of interpreting computer program instruction and processes data. Computer Output refers to processed data called information. Output is the process of transmitting the processing data into a form that makes sense to humans.
Computer Output devices are those use to display data that has been processed either in hardware or software form to make sense to an individual or group of persons.
They are simply defined as any device used by a computer to communicate information in a usable form. Information is referred to as the result of processed data that makes sense in life. Computer storage refers to the action of a computer that permits it to store data and information, while computer storage devices refer to those devices responsible for the storing of these data and information.
A computer storage device is a mechanical apparatus that has the ability to store data and also retrieve this data. Those devices that store data for a long time are said to be permanent storage devices while those that store data or information for a short time are referred to as temporal storage devices. This refers to those storage devices which are incorporated with the motherboard of the system.
They have a small storage capacity. It stores information temporarily for the purpose of processing and loses the information in case of power failure. Hence it is the term volatile memory. As the name implies, information or data stored on this device will be lost in case of power failure.
It stores data temporarily in order to feed the processor with data to be processed and also stores information temporarily after processing before onward storage to secondary storage HDD. This memory can permit information to be read from it and to be written to it.
This memory stores information permanently. From the name read-only, information on this memory can only be read, it cannot be added, replace, or deleted. In clear terms read-only means the information cannot be edited. It contains information for starting up the computer. The information is said to be hard-wired on the motherboard of the computer.
These are storage devices that have the ability to store data for a long period of time. They can only store data or information but they cannot carry out any control, logical, or arithmetic function. Their example includes; Hard disk, Flash disk, Memory card, etc. These devices are externally attached to the computer system unit or connected to the computer using a bus cable.
Information on these devices is being stored to be used by a computer user when need be. They will retain their information in case of power failure. They generally have high storage capacity and information or data on it may be edited. NOTE: Some devices such as digital cameras and touch screen functions both as input and output. An information processing system is a system which takes information from one form be it electrical, mechanical or biological and process transform it to another form by an algorithmic process.
An example of such a system is the computer. The diagram below clearly explains the input, processing, and output devices and how they function. Chat With An Agent. Skip to content Menu Close Computer Input, Processing, Output and Storage Devices Understanding the classification of computer input, processing, output, and storage devices in accordance with their function helps students or computer users clearly distinguish between the various components of the computer system.
Computer input devices Examples include; keyboard, mouse, joystick, Webcam, etc. Computer primary and secondary storage devices. Software stored on the ROM is often called firmware because is more like hardware than software. Informative System: An information processing system is a system which takes information from one form be it electrical, mechanical or biological and process transform it to another form by an algorithmic process.
