Question 16

Define a Graphical User Interface and give one use of the this type of HCI.

Answer 16

With a GUI, the end-user points and clicks on icons, buttons and menus using their mouse, touch screen, keyboard or other device.
A GUI is the most common interface for software applications, mobile apps, and operating systems. It is designed to be very intuitive to use, without needing much text.

Question 17

What is the interface used for software applications, mobile apps, and operating systems?

Answer 17

Graphical User Interface (GUI)

Question 18

What does GUI stand for?

Answer 18

Graphical
User
Interface

Question 19

Define a Command-Line Interface (C/LI) and give one use of this type of HCI.

Answer 19

A Command-Line Interface is text-only and is used to create sequential lines of code. The user has to type in commands in a programming language. The code runs when they press enter.
An experienced technical person would use a CLI when they need to run commands quickly. For example, to find information about network configuration.

Question 20

An experienced technical person would use what when they need to run commands quickly?

Answer 20

A Command-Line Interface (C/LI)

Question 21

What does C/LI stand for?

Answer 21

Command
Line
Interface

Question 22

Define a form-driven interface and give one use of this type of HCI.

Answer 22

With a form-driven interface, the user is presented with a list of options and fields to fill in. Each field is likely to have validation checks.
A user registration webpage is an example of a form-driven interface. The user has to fill in their name, address and other personal details. Some fields, such as country, may be available as a drop-down menu.

Question 23

A user registration webpage is an example of what?

Answer 23

A form-driven interface.

Question 24

Describe an advantage of a Graphical User Interface (GUI).

Answer 24

A GUI makes the operation of the computer as friendly as possible by using high resolution graphics and pointers. Instead of typing in commands you enter them by pointing and clicking.

It should be intuitive and fun to use without additional instructions. There is no need to know programme commands. It is easier to customise an application or environment using a GUI.

Question 25

What makes the operation of the computer as friendly as possible by using high resolution graphics and pointers?

Answer 25

Graphical User Interface (GUI)

Question 26

What should be intuitive and fun to use without additional instructions?

Answer 26

Graphical User Interface (GUI)

Question 27

Describe an advantage of a Command Line Interface (C/LI).

Answer 27

A Command Line Interface uses very little processing power and is therefore fast to execute (run). You don’t have to go through lots of menus, so it is a quicker way to enter commands.

Question 28

What uses very little processing power and is therefore fast to execute (run)?

Answer 28

Command Line Interface (C/LI)
