Explanation / Answer
An information system (IS) is an organized system for the collection, organization, storage and communication of information. More specifically, it is the study of complementary networks that people and organizations use to collect, filter, process, create and distribute data.[according to whom?]
"An information system (IS) is a group of components that interact to produce information."[1]
A computer information system is a system composed of people and computers that processes or interprets information.[2][3][4][5] The term is also sometimes used in more restricted senses to refer to only the software used to run a computerized database or to refer to only a computer system.
Information Systems is an academic study of systems with a specific reference to information and the complementary networks of hardware and software that people and organizations use to collect, filter, process, create and also distribute data. An emphasis is placed on an information system having a definitive boundary, users, processors, storage, inputs, outputs and the aforementioned communication networks.
The term educational technology refers to the use of technology in educational settings, whether it be elementary and secondary schools, colleges and universities, corporate training sites, or independent study at home. This discussion, however, will focus on educational technology in grades K—12.
Educational technology has both general and specialized meanings. To the lay public and to a majority of educators, the term refers to the instructional use of computers, television, and other kinds of electronic hardware and software. Specialists in educational technology, in particular college and university faculty who conduct research and teach courses on educational technology, prefer the term instructional technology because it draws attention to the instructional use of educational technology. This term represents both a process and the particular devices that teachers employ in their classrooms. According to the Association for Educational Communications and Technology, one of the principal professional associations representing educational technologists, "Instructional Technology is a complex, integrated process involving people, procedures, ideas, devices, and organization for analyzing problems, and devising, implementing evaluating, and managing solutions to these problems, in situations in which learning is purposive and controlled."(p. 4). Educational technologists often employ the term instructional media to represent all of the devices that teachers and learners use to support learning. However, for many educators the terms educational technology, instructional media, and instructional technology are used interchangeably, and they are used so here. In addition, the principal focus will be upon the most modern computational and communication devices used in schools today.
Input Devices
The devices which are used to give data and instructions to the computer are called Input Devices. Various types of input devices can be used with the computer depending upon the type of data you want to enter in the computer, e.g., keyboard, mouse, joystick, light pen, etc
Keyboard
It is the most commonly used input device. It is used to enter data and instructions directly into the computer. There are 104 buttons on the keyboard which are called keys.
Joystick and Game-pad
Joystick and game-pad are also input devices which are also input devices which are used to control the movement of object on the screen. Just like mouse, these are also pointing devices. Mostly they are used for playing games on the computer.
The joystick has a vertical stick with a track ball at its bottom. While playing the games on the computer, the userneeds to move the objects quickly on the screen. With the movement of this vertical stick the objects can be moved in all the directions easily.
A game-pad is a type of game controller held in two hands, where the fingers (especially thumbs)are used to provide input by pressing buttons on it. It is also known as Control Pad.
Mouse
Mouse is another input device which is commonly found connected with the computers. It is basically a pointing device which works on the principle of Point and Click. When the mouse is moved on the mouse pad, a light beam underneath reflect to give motion to the pointer on the screen
Light Pen
Light pen is another pointing type input device. It is a pen shaped device which can be used by directly pointing the objects on the screen. It can also be used for making drawings directly on the monitor screen.
Scanner
We can store pictures, photographs, diagrams into the computer with the help of scanner. The scanner reads the image and saves it in the computer as a file
Touchscreen
Touchscreen is a special computer screen that takes the input by sensing the touch of a human finger, gloved hand, stylus, pen or any other pointing device. The user gives instructions to the computer just by touching the screen
Microphone
This is an input device which is used to record sound or voice into the computer system. You can store voice data in the computer by speaking in front of this device.
A trackball is similar to a mouse but is mounted in a fixed position. The user spins the ball with fingers to move the pointer on the screen.
A Trackball technology was used in earlier laptop computer which is now replaced with track-pad.
Output Devices
The devices which are used to display the results or information are called Output Devices. You can view the output on the monitor or you can print it on a paper using a printer. Monitor and the printer are the commonly used output devices.
Monitor
This is the most common output device connected with the computer to display the processed information. It looks like a TV and is also know as VDU(Visual Display Unit). Pictures are displayed by using a large number of very small dots on screen called pixels. The number of pixels that a monitor can show on its screen is referred to as the resolution of the screen.
The two commonly used monitor types are:
The output produced on the screen is called Soft Copy Output because it cannot be retained for a long time.
Nowadays LCD monitors are more popular as their sharp picture quality. They are light weighted and flat screen monitors.
Printer
This is an important output device of the computer system. It gives a printed output of the results that appears on the monitor screen. Printed output is also called Hard Copy output because unlike monitor, this output can be preserved even if the computer is switched off.
Printers are of different types. On the basis of their printing techniques, printers are grouped as follows:
1.Character printer
2.Line printer
3.Page printer
Character Printer
Character printer prints one character at a time; it prints at the speed of around 30 to 600 characters per second.
Dot Matrix printer is an example of a character printer.
Dot Matrix Printer
This type of printer works like a typewriter. It creates an impression on the paper by pressing the end of pins fixed in its print heads, against an inked ribbon. This printer is noisy with a low print quality. Its speed is measured in CPS(Characters Per Second).
Line Printer
This is high speed printer that prints one line at a time. It is used when large quantity of output is required as it produces the quick output. Examples of a Line printer are Drum printer and the Chain printer. The noise level of these printers is high and speed ranges from 200 to 2000 LPM(Lines Per Minute).
Page Printer
Page Printer prints a whole page at a time. Examples of these printers are inkjet printer or a Line printer because it has to store each page in memory before printing it.
Inkjet Printer
This type of printer prints by spraying tiny ink droplets on the paper. It can print in both, color as well as black and white. The print quality of this printer is better than that of Dot Matrix Printer and it prints without making any noise. Its speed is measured in PPM(Pages Per Minute).
Laser printer
In this type of printer, laser beam technology is used to print the text or graphics on the paper. The speed of this printer is very fast and it gives out very fine quality prints. It’s speed is also measured in PPM
Laser printer
In this type of printer, laser beam technology is used to print the text or graphics on the paper. The speed of this printer is very fast and it gives out very fine quality prints. It’s speed is also measured in PPM
Plotter
We can get the print of a photograph, drawing, image stored in the computer, by using a plotter. It is an output device which provides a high quality of printed output. It is generally used by engineers and architects
