Q

What are the Seven Information Processes?

A
Collecting
Organising
Analysing
Storing and Retrieving
Processing
Transmitting and Recieving
Displaying
2
Q

What is Organising?

A

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

3
Q

What is Storing and Retrieving?

A

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

4
Q

What is Processing?

A

A procedure that manipulates data and information.

5
Q

What is Transmitting and Recieving?

A

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

6
Q

What is Displaying?

A

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

7
Q

What is Collecting?

A

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

8
Q

What is Structuring of Data?

A

The structure is the design that suits the information.

9
Q

What is Representing?

A

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

10
Q

What is Analysing?

A

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

11
Q

What does the term ‘multimedia’ involve?

A
Text
Numbers
Image
Audio
Video
12
Q

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

A

ASCII (American Standard Code for Information Interchange)

EBCDIC (Extended Binary Coded Decimal Interchange Code)

13
Q

How does ASCII gets to be represented?

A

It uses a decimal number range from 0 to 127

14
Q

What do Bitmaps mainly represent?

A

They represent every single element or dot in a picture

15
Q

How do Vectors represent images?

A

Vectors represent by building every portion of the Image mathematically

16
Q

How does Audio work in Binary?

A

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

17
Q

What is Sampling?

A

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.

18
Q

What’s an Individual Note?

A

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

19
Q

What’s the most common storage for traditional music?

A

MIDL (Musical Instructments Digital Interface)

20
Q

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

A

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

21
Q

What is Video?

A

The combination of Image and Sound to present Information.

22
Q

What is Digital Data?

A

Digital Data is data that is coded by using numbers
