Week 5

Question 1

• increase dramatically the more often a human being is involved in identifying an object, inputting that information into a database, and then modifying the knowledge to keep track of changes in location, pack size, quantity, and so on.

Answer 1

Errors and time

Question 2

Is a major tool in capturing critical data quickly and accurately.

Answer 2

Bar coding

Question 3

is an optical method of achieving automatic identification. It relies on visible or invisible light being reflected off a printed pattern.

Answer 11

Bar code symbol

Question 12

A bar code symbol typically consists of five parts:

Answer 12

Leading quiet zone
Start character
Data character
Stop character
Trailing quiet zone

Question 13

refers to the width of the narrowest line or bar in a bar code.

Answer 13

X dimension

Question 14

refers to the “clear” area preceding the Start character and the area immediately following the Stop character of the bar code.

Answer 14

Quiet zone

Question 15

refers to the human understood text used alongside bar code symbols. Corning Life Sciences places this human readable left of the bar code symbol.

Answer 15

Human readable

Question 16

The portion of the bar code that can be read and understood by humans.

Answer 16

Human readable

Question 17

This readable part of the symbology represents the

Answer 17

bar code contents.

Question 18

When the sequence number continues with the customer’s next order regardless of if they are ordering a new product or reordering a previous product.

Answer 18

Shared sequences

Question 19

A distinct character or pattern of bars used at the beginning and end of each bar code symbol, which identifies to the scanner the beginning and end of the data and direction of read information to the decoding logic. These characters are embedded in the bar code and are not visible in the human readable.

Answer 19

Start/stop Characters or patterns

Question 20

The area preceding the beginning of a bar code and following the end of the bar code, sometimes called the clear area.

Answer 20

Quiet zone

Answer 21

X-dimension

Question 22

are generally referred to as multiples of the X-dimension

Answer 22

wider elements

Question 23

Bar Coding Structural Rules

Answer 23

Symbologies

Question 24

controls how information will be encoded in a bar code symbol. Just as there are different languages such as French, English, Spanish, Italian, Russian, Japanese, and Chinese, there are different symbologies.

Answer 31

Character set

Question 32

This symbology is the most widely used bar code in nonretail applications. It was first introduced in 1975.

Answer 33

Code 39

Question 34

Code 39 is sometimes referred to as
