1. Keyboard - The keyboard is a way to input letters or numbers into different applications or programs. A keyboard also has special keys that help operate the computer.
2. Mouse - The mouse is used to open and close files, navigate web sites, and click on a lot of commands (to te
There are many input formats which enable us to gather up and collect information, and enter data and instructions into the computer.
Input devices can be manual or automatic.
Manual input devices include:
Keyboard - including concept keyboard. This is a flat board...
Input and output devices
What are input and output devices? Why do we need them?
Input devices are things that are needed to work the computer, things like a: mouse, keyboard etc. or for a console, controller and gamepad. Output devices are things you can plug in and are not necessarily needed i
INPUT AND OUTPUT DEVICES
In computing, input/output, or I/O, refers to the communication between an information processing system (such as a computer), and the outside world possibly a human, or another information processing system. Inputs are the signals or data received by the system, and output
A THOROUGH OVERVIEW OF INPUT AND OUTPUT DEVICES
PRESENTED BY THE MEMBERS OF GROUP B COMPUTER SCIENCE DPT.
• The I/O devices as parts of the components of an information processing system or a computer system are those devices which enables the computer system to communicate with

1. Scanning devices
An optical scanner is a hardware input device that allows a user to take an image or text and convert it into a digital file, allowing the computer to read or display the scanned object. Features of the optical scanner include-its design, software compatibility
INPUT OUTPUT MODEL
In economics, an input-output model is a quantitative economic technique that represents the interdependencies between different branches of national economy or between branches of different, even competing economies. Wassily Leontief (1905-1999) developed this type
Central Processing Units
Once data have been captured, they usually must be processed to be valuable to decision makers and these processing tasks are performed by the central processing unit (CPU) of a computer system. A central processing unit (CPU), also referred to as a central processor unit,
Importance of Input/Output
However, music stored on a CD is read sequentially, so rotation speed is not an issue. Data on floppy disk Refers to the 3½", 5¼" and 8" floppy disks, because when waved around they are floppy (at least the 5¼" discs were very flexible). Floppy discs are Computers a
Input/ Output Storage Paper
Accuracy of data input is important. It is important to know, not so much where the data comes from or how it is processed but whether the results are useful and valuable. There are many different applications to consider when deciding which method is best for data i
This paper will take a closer look at data input and also data output considerations. There are many different choices when it comes to data input/output options. While it is good to have many choices, there are usually some considerations that are required to make the best possible de
Data Input, Output, Storage and Access Methods
The purpose of this paper is to highlight some best practices for data input and output. In addition, this paper will highlight appropriate uses of various storage means. Lastly, it will address the effect certain components of a computer have on its
