Introduction to Information Systems and Data

Question 1

What are the Seven Information Processes?

Answer 1

Collecting
Organising
Analysing
Storing and Retrieving
Processing
Transmitting and Recieving
Displaying

Question 2

What is Organising?

Answer 2

The information process by which data is structured into a form appropriate for the use of other information processes.

Question 3

What is Storing and Retrieving?

Answer 3

The process by which data and information is saved and accessed later.

Question 4

What is Processing?

Answer 4

A procedure that manipulates data and information.

Question 5

What is Transmitting and Recieving?

Answer 5

The process that sends and receives data and information within and beyond information systems.

Question 6

What is Displaying?

Answer 6

The process that controls the format or information presented to the participant or user.

Question 7

What is Collecting?

Answer 7

The process by which data is entered into our database, captured by a computer system, including:

Deciding what data is required
How it is sourced
How it is encoded for entry into the system

Question 8

What is Structuring of Data?

Answer 8

The structure is the design that suits the information.

Question 9

What is Representing?

Answer 9

Representing is the coding of every individual essence of data that allows the data to be used by other information systems.

Question 10

What is Analysing?

Answer 10

The process by which data is interpreted, transforming it into information.

Question 11

What does the term ‘multimedia’ involve?

Answer 11

Text
Numbers
Image
Audio
Video

Question 12

What are the two methods commonly used to represent digital text?

Answer 12

ASCII (American Standard Code for Information Interchange)

EBCDIC (Extended Binary Coded Decimal Interchange Code)

Question 13

How does ASCII gets to be represented?

Answer 13

It uses a decimal number range from 0 to 127

Question 14

What do Bitmaps mainly represent?

Answer 14

They represent every single element or dot in a picture

Question 15

How do Vectors represent images?

Answer 15

Vectors represent by building every portion of the Image mathematically

Question 16

How does Audio work in Binary?

Answer 16

Two ways: catching the actual sound at precise intervals of time and describe the sound in terms of the properties of each individual note.

Question 17

What is Sampling?

Answer 17

It’s the Level, or instantaneous amplitude, of the signal that was recorded at precise intervals as each sample is stored as a binary number.

Question 18

What’s an Individual Note?

Answer 18

An Individual Note is basically a representation of a musical note that determines pitch and duration.

Question 19

What’s the most common storage for traditional music?

Answer 19

MIDL (Musical Instructments Digital Interface)

Question 20

How does Binary Representations of musical notes compare to similar sound systems?

Answer 20

Binary Representations are way more smaller and need more processing power to turn the data into sound waves.

Question 21

What is Video?

Answer 21

The combination of Image and Sound to present Information.

Question 22

What is Digital Data?

Answer 22

Digital Data is data that is coded by using numbers
