Automatic Data Capturing Techniques
Definition:
Automatic identification and data capture (AIDC) refers to the methods of automatically identification objects, collecting data about them, and entering them directly into computer system, without human involvement.
Types of Automatic Data Capturing:
By using these devices, data is captured without the human involvement. Important Automatic Data Capture Devices & Methods are discuss below:
1: Optical Character Recognition: (OCR)
OCR technology is used to convert different types of machine-printed documents including image files, PDF files or scanned paper documents, into searchable and editable data.
2: Intelligent Character Reorganization: (ICR)
ICR technology helps to recognize and capture handwritten printed characters from image files. As handwritten text caries significantly, so ICR is less accurate and complicated as compared to other technologies. However, the technology evolves continuously by itself and as the number of samples processed increases, the accuracy increases. This self-learning process differentiates it from others and gives it the name of ‘intelligent’.
3: Optical Mark Reading: (OMR)
OMR technology is used to capture human marked data from documents such as forms and surveys. The technology has the capacity to differentiate between marked and unmarked boxes and so, is used for capturing data through boxes that are checked manually on documents.
4: Magnetic ink character recognition: (MICR)
It is a data capture technology capable of recognizing characters. It involves the recognition of specially formatted characters that are printed in magnetic ink, by a machine. The technology is mainly used by banking industry to speed up the processing of cheques and other documents. The added advantage of this method is that humans can also read the data as well.
5: Magnetic stripe card:
Magnetic stripe cards store data using magnetic properties of certain materials. They possess stripes of iron-based magnetic materials on the card. They are used for electronically storing particular numbers related to credit cards, identity cards and they enable automated data transfer when they re-swiped in magnetic readers.
6: Web data capture:
Data capture from web involves the capture of data from electronic forms through internet.


7: Radio Frequency Identification: (RFID)
Radio frequency identification used for automatic data capture which allow contact-less identification of objects via Radio frequency (RF).
8: Bar Code:
•        Bar code is a predefined format of dark black and white spaces.
•        Represents alphabets and numeric data.
•        Structured to contain specific piece of information.
•        Allow real time data to be collected accuracy and rapidly.

•        Improves performance, profitability and productivity.

(1) Additive Property When a property of a substance is equal to the sum of the Corresponding properties of the constituent atoms, it is called an additive property . For example, molecular mass of a compound is given by the sum of the atomic masses of the constituent atoms. (2) Constitutive Property A property that depends on the arrangement of atoms and bond structure, in a molecule, is referred to as a constitutive property . Surface tension and viscosity and optical activity are examples of constitutive property. (3) Additive and Constitutive Property An additive property which also depends on the intermolecular structure is called additive and constitutive property. Surface tension and viscosity are such properties. (4) COLLIGATIVE PROPERTIES Colligative Properties (Greek colligatus = Collected together). A colligative property may be defined as one which depends on the number of particles in solution and not in any way on the size or chemical nature of

Ø SPEED: Computer is very fast calculating device It can execute basic operations like addition, multiplication, subtraction and division at a few microseconds. Ø ACCURACY: The accuracy of computer does not go down when they are used continuously for hours together. It always gives accurate results. Ø STORAGE: Computer has a very large storage capacity. It has an in-built memory where it can store a large amount of data. We can also store data in secondary storage devices like Floppy disk, Hard disk etc. Ø VERSATILITY: It means computer can perform different types of job efficiently. Computer can work with different types of data and information such as visuals, text, graphics & video etc. at same time. Ø PAPER WORK REDUCED: The computer reduces the paper work of any organization. The required data which was earlier stored in files, drawers and cabinets is now stored in the memory of computer. So Organization can reduce the paper work.  Ø MANP

Two Stroke vs Four Stroke Enigne – Advantages and Disadvantages of Two Stroke over Four Stroke Cycle Engines. In a two stroke engine, the working cycle is completed in two strokes of the piston or one revolution of the crankshaft. In a four stroke engine, the working cycle is completed in four strokes of the piston or two revolutions of the crankshaft. The following are the advantages and disadvantages of two stroke over four stroke cycle engines: Advantages: 1.   A two stroke cycle engine gives twice the number of power strokes than the four stroke cycle engine at the same engine speed. Theoretically, a two stroke cycle engine should develop twice the power as that of a four stroke cycle engine. 2.    For the same power developed, a two stroke cycle engine is lighter, less bulky and occupies less floor area. 3.    A two stroke cycle engine has a lighter flywheel and gives higher mechanical efficiency than a four stroke cycle engine. Disadvantages: 1.   The thermal
