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
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. Five factors you should consider when assessing the suitability of hardware device for connecting to a computer is;
2. When installing a new component into a computer system the tasks involved are;

This paper will be explaining four examples of the United States federal government expansion between the beginning of the Civil War and the end of the Civil Rights Era. This paper will have three contexts that are important to the development of the United States. These contexts are poli
Gesture detection – the detection of human movements – may be used to enable advanced, differentiated smart features in portable electronics such as smart phones. Many of these features save energy by enabling electronics to expend the minimum amount of energy neces
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

Methods of Data Input, Output, Storage and Speed
We all should know and understand that accuracy of data input is important. In today’s soci
Data is factual information and it needs to be accurately captured in order to be processed. There are many methods to input data and each situation warrants a different method. There can be several different ways to input the information and it can be done in an automatic fashion, as with
The need for accurate data is evident. Systems and procedures are needed to ensure the accuracy and completeness of the information being recorded and understanding the role hardware as well as software plays is important in acquiring the correct resources for any project.
Accuracy of Data
Thus the basic functions of an OS are –
1. Process Management – Managing the programs that are running.
2. Memory Management – Managing and rationing the memory between processes and data.
3. Storage Management – Managing the permanent Storage of data on disks or other media
