Differences between barcode reader and character recognition devices​

Computers and Technology

A barcode reader is an optical scanner that reads printed barcodes. Barcodes are visual representations of data that convey information by varying the widths and spacings of parallel lines. Barcode readers consist of a light source, a lens and a light sensor. On the other hand, an optical character recognition device is a device that converts images of typed or handwritten text into machine-encoded text.

These systems are similar because they both use optical recognition. They are also similar in the sense that they both scan data. However, they can be quite different. A barcode reader is simply designed to obtain a single piece of data from a barcode, while a character recognition device can gather extensive information about text, including formatting. Moreover, a barcode reader can only read a barcode made with the correct specifications. Character recognition devices are more flexible and versatile, being able to read printed material, billboards, subtitles on images, etc.

<u><em>Differences between barcode reader and character recognition devices​:</em></u>

Barcode Reader or Barcode Scanner:  

  • Barcode Scanner scans the data by brightening the barcodes usingSensor
  • The analog signal is then converted into digital signal by Converter.
  • The Decoder calculates the converted data and sends valid data to the computer.  

Character Recognition Devices (OCR):

  • OCR scans the physical document and converts them into two-coloured format.
  • The darker and lighter area are identified as characters and blanks respectively.
  • The common methods used are: Pattern Recognition and Feature Detection.

Write a recursive function sumAll that accepts an integer argument and returns the sum of all the integers from 1 up to the numb
slavikrds [6]

Answer:

int sumAll(int n)//function definition.

{

   if(n==1)//if condition.

   return 1;

   else//else condition.

   {

       return n+sumAll(n-1);//return the value and call the function in recursive manner.

   }

}

Explanation:

  • The above-defined function is a recursive type function that is written in the c language, which holds the if and else condition.
  • When the user passes the largest value from 1, then the else condition will be executed which adds the largest value and pass the value after the decrement of the value as an argument.
  • When the value will become 1, then the function if-block will be executed which returns the value and ends the calling function recursively.

Intro to cs 3.7 edhesive g=float(input("Enter your English test grade:")) if(g&lt;=64): print("F") if (g&gt;=65 and g&lt;69): pr
qwelly [4]

Answer:

The correct code for this question:

g=float(input("Enter your English test grade:")) #take input from user.

#check conditions

if (g>=100 and g<=90):

print ("A")

#g greater then equal to 100 and less then equal to 90.

if (g>=89 and g<=80):

print("B")

#g greater then equal to 89 and less then equal to 80.

if (g>=79 and g<=70):

print("C")

#g greater then equal to 79 and less then equal to 70.

if (g>=69 and g<=65):

print("D")

#g greater then equal to 69 and less then equal to 69.

if(g<=64):

print("F")

#g less then equal to 64.

else:

print ("Not a grade")

#not a grade or fail.

Explanation:

In this program, we use to take a value from the user and check the value from the various conditions. To check all the condition we use if-else statement and AND operator that check to the range to together.

If -else is a conditional operator. In that, If block is used to check the true part and else part takes false value, and AND is a logical operator that check the two range together

What two actions does the RETI instruction perf orm? Why must these two actions be done in a single instruction, as opposed to a
Bas_tet [7]

Answer:

In assembly language, two instructions control the use of the assembly language procedure.

  • CALL
  • RET

CALL pushed the control to the return address onto the stack and transferred the control.

RET instruction returns the address that placed on the stack by a call instruction.

Explanation:

Action RET instruction

  • The RET instruction pops the address and returns off the stack, which is pointed by the stack pointer.
  • The stack is LIFO in memory at a particular location, and the pointer points offset from the stack location.

RET instruction does its job by consulting the register and memory state at the point when it is executed.

In RET instruction, only register and memory state is executed. Call instruction must save that address that figure out in a register and memory location.
