Deck 16: Input Design and Prototyping

Question 1

Data capture is the identification and acquisition of new data.

Answer 1

True

Question 2

Source documents are forms used to record business transactions in terms of data that describes those transactions.

Answer 2

True

Question 3

Data entry is the identification and acquisition of new data.

Answer 3

False

Question 4

In batch processing, the entered data is collected into files called batches. Each file is processed as a batch of many transactions.

Question 5

In on-line processing, the captured data is processed immediately.

Question 6

In on-line processing, the entered data is collected into files. Each file is stored on-line, and processed as a unit to update all of the entered transactions at the same time.

Question 7

Batch processing is barely used anymore.

Question 8

In remote batch processing, data is entered using on-line editing techniques; however, the data is collected into a batch instead of being immediately processed. Later, the batch is processed.

Question 9

A simple example of remote batch processing uses a PC-based front-end application to capture and store the data. The data can later be transmitted across a network for batch processing.

Question 10

Keyboard data entry remains the most common form of input.

Question 11

A mouse is a pointing device used in conjunction with graphical user interfaces. It has made it easy to navigate on-line forms and click on commands and input options.

Question 12

An emerging technology that will greatly impact input design is the touch screen display. Such displays are common in handheld and palm-top computers that are finding their way into countless information system applications.

Question 13

Point of sale terminals are used to capture data at the point of sale and provide time-saving ways to enter data, perform transactional calculations, and produce some output. Most can scan and read bar codes to eliminate keying errors.

Question 14

Automatic teller machines (ATMs), another form of point of sale terminal, are operated by the consumer.

Question 15

Automatic teller machines (ATMs) are remote batch processing devices.

Question 16

Automatic data capture (ADC) techniques are designed with the goal of eliminating human intervention associated with data input methods.

Question 17

The most common example of automatic data capture (ADC) is the use of a keyboard.

Question 18

The classic example of optical mark recognition is the use of optical mark forms for objective-based questions on examinations.

Question 19

Optical character recognition (OCR) is less prevalent despite its maturity.

Question 20

Optical mark recognition requires the user or customer to carefully handwrite input data on a business form.

Question 21

MICR is most widely used in the banking industry.

Question 22

Electromagnetic ADC technology is based on the use of radio frequency to identify physical objects. It involves attaching a tag and antenna to the physical object that is to be tracked. The tag contains memory that is used to identify the object being tracked.

Question 23

Electromagnetic ADC technology is based on the use of television frequency to identify physical objects.

Question 24

Smart cards are slightly thicker than credit cards and contain a microprocessor, memory circuits and a battery. They represent a portable storage medium from which input data can be obtained.

Question 25

Smart card applications are particularly promising in the area of health records where a person's blood type, vaccinations, and other past medical history could be made readily available.

Question 26

Biometric ADC technology is based on unique human characteristics or traits, for example, fingerprints, voice pattern, retinal pattern.

Question 27

Biometric automatic data capture is popular because it offers the most accurate and reliable means for identification. This technology is particularly popular for systems that require security access.

Question 28

Because inputs originate with system users, human factors play a significant role in input design.

Question 29

Human factors play only a minor role in input design.

Question 30

One of the general principles for input design is: "Capture only variable data."

Question 31

"Capture only static data" is one of the general principles for input design.

Question 32

"Do not capture data that can be calculated or stored in computer programs" is one of the general principles for input design.

Question 33

"Capture data that can be calculated or stored in computer programs" is one of the general principles for input design.

Question 34

The volume of data input should be minimized as much as possible.

Question 35

The volume of data input should be maximized as much as possible.

Question 36

If source documents are used to capture data, they should be easy for system users to complete and subsequently enter into the system.

Question 37

A suggestion to help with the use of source documents to capture data is to include instructions for completing the form, preferably at the beginning of the form.

Question 38

A suggestion to help with the use of source documents is to minimize the amount of handwriting required to complete the form.

Question 39

A suggestion to help with the use of source documents is to maximize the amount of handwriting required to complete the form.

Question 40

A suggestion to help with the use of source documents is that data should be sequenced on paper so that it can be read much like a book, from top to bottom, left to right. The system user should not have to move from right-to-left or jump around on the form.

Question 41

When possible, use input designs based on known metaphors. Not all inputs lend themselves to metaphors (such as a checkbook), but some are greatly enhanced by the imitation.

Question 42

Internal input controls ensure that the data input to the computer is accurate and that the system is protected against accidental and intentional errors and abuse, including fraud.

Question 43

An internal input control guideline is: "The number of inputs should be monitored." This is especially true with the batch method because source documents may be misplaced, lost or skipped.

Question 44

It is not necessary to monitor the number of inputs to a batch, because the computer is more capable of tracking and counting them.

Question 45

Two types of errors can infiltrate entered data: data entry errors and invalid data recorded by system users.

Question 46

Existence checks determine whether the input data for each field falls within the legitimate set or range of values defined for that field.

Question 47

Data type checks ensure that the correct type of data is input. For example, alphabetic data should not be allowed in a numeric field.

Question 48

Data type checks determine whether all required fields on the input have been entered. Required fields should be clearly identified as such on the input screen.

Question 49

Domain checks determine whether the input data for each field falls within the legitimate set or range of values defined for that field.

Question 50

Domain checks determine whether a known relationship between two fields is valid.

Question 51

Combination checks determine whether a known relationship between two fields is valid. For example, if the vehicle make is Pontiac, the vehicle model must be one of a limited set of values that comprises cars manufactured by Pontiac.

Question 52

Combination checks determine whether all required fields on the input have actually been entered.

Question 53

Self-checking digits determine whether the input data for each field falls in the legitimate set or range of values defined for that field.

Question 54

Format checks compare data entered against the known formatting requirements for that data.

Question 55

Format checks determine data entry errors on primary keys. A format check digit is a number or character that is appended to a primary key field.

Question 56

In repository based programming, a repository contains input controls and code. The developers can, in a single location, define most of the properties and constraints for a reusable field and the data validation code for that field. Once defined, the object or control can be used by any number of other systems analysts and programmers in the organization. This approach guarantees that every instance of the field will be used in a consistent manner. Furthermore, the repository entries can be changed if business rules dictate and no additional changes to the applications will be required.

Question 57

A text box requires the user to type the data inside the box. It can allow for single or multiple lines of data characters to be entered.

Question 58

A text box is most appropriately used when the input data values are unlimited in scope and the analyst is unable to provide the users with a meaningful list of values from which they can select.

Question 59

A text box should be accompanied by a descriptive, meaningful caption.

Question 60

It is not necessary to provide a caption for a text box, since the content should be obvious by its placement on a screen or form.

Question 61

A caption for a text box should be located to the left of the actual text box or left-aligned immediately above the text box.

Question 62

A caption for a text box should be located to the right of the actual text box or right-aligned immediately above the text box.

Question 63

Generally, the size of the text box should be large enough for all characters of the fixed-length input to be entered and viewed by the user. When the length of the data to be input is variable and could become quite long, the text box's scrolling and word-wrapping features should be applied.

Question 64

Generally, the size of a text box does not matter.

Question 65

Radio buttons provide the user with an easy way to quickly identify and select a particular value for a value set.

Question 66

Radio buttons normally appear in groups - one radio button per value choice.

Question 67

Radio buttons are most appropriate when a user may be expected to input data that has a limited predefined set of mutually exclusive values.

Question 68

Radio buttons are most appropriate when a user may be expected to input data that has a large predefined set of choices, especially where more than one choice can be selected simultaneously.

Question 69

Radio buttons should present the alternatives vertically aligned and left-justified to aid the user in browsing.

Question 70

Radio buttons should present the alternatives horizontally aligned and right-justified to aid the user in browsing.

Question 71

With radio buttons, the group of choices should be visually grouped to set them off from other input controls appearing on the screen.

Question 72

Radio buttons should be used when you want to select a value that is simply a Yes/No.

Question 73

A check box consists of two parts: a square box followed by a description of the input field for which the user is to provide the Yes/No value.

Question 74

A check box acts as a toggle switch on an input value.

Question 75

A radio button acts as a toggle switch on an input value.

Question 76

A list box is a control that requires the user to select a data item's value from a list of possible choices. A list box is rectangular and contains one or more rows of possible data values. The values may appear as either a textual description or graphical description.

Question 77

Scrolling capabilities make list boxes appropriate for use in those cases where there is limited screen space available and the input data item has a large number of predefined, mutually exclusive values from which to choose.

Question 78

Scrolling capabilities make radio buttons appropriate for use in those cases where there is limited screen space available and the input data item has a large number of predefined, mutually exclusive values from which to choose.

Question 79

A drop-down list is a control that requires the user to select a data item's value from a list of possible choices. A drop-down list consists of a rectangular selection field with a small button connected to its side (that contains a picture of a downward arrow). The downward arrow button is to suggest to the user the existence of a hidden list of possible values for a data item.

Question 80

A drop-down list should be used in those cases where the data item has a large number of predefined values and screen space availability prohibits the use of a list box.
