Command line interface (CLI) requires a user to type in instructions to choose options from menus, open software and so on. There are often a number of commands that need to be typed in, for example, to save or load a file. The user therefore has to learn a number of commands just to carry out basic operations.
According to this definition, Which user is more adequate to use a CLI?.
A programmer, analyst or technician
The end-user who doesn't have (or doesn't need) any great knowledge of how the computer works
Graphical user interface (GUI) allows the user to interact with a computer (or MP3 player, gaming device, mobile phone, and so on) using pictures or icons (symbols) rather than having to type in a number of commands
According to this definition, Which user is more adequate to use a GUI?.
A programmer, analyst or technician

A sensor is a device that inputs data to a computer; the data is a measurement of some physical quantity that is continuously changing (for example, temperature, light, moisture, etc.). These physical quantities are analogue in nature. Since computers only understand digital data (Is and Os), the information from the sensors needs to be converted; this is done using an analogue to digital converter (ADC).

Optical character recognition (OCR) is the name given to software that takes scanned text and converts it into a computer-readable form. The text can then be used in various application packages such as word processors, desktop publishing and presentation software.
Think in a situation you could use this software.
Optical mark recognition (OMR) is a device that can read marks written in pen or pencil. The places where the pen or pencil marks can be made are clearly shown in the image on the right (in this example, the numerical lozenge is shaded in each response using a pen). The position of the mark is stored in the computer's memory after being read by the OMR device.
Think when you use this type of technology?
