What does ROM stand for?

• Random Access Memory

• Random Ordinary Memory

• Repeated Ordinary Memory

• Read-Only Memory

Answer explanation

ROM memory is fixed and non-volatile, which means it is NOT lost when the computer is turned off.

Which of these is NOT some kind of computer storage?

• GPU

• RAM

• SSD

• ROM

Answer explanation

A GPU (Graphics Processing Unit) is primarily used for rendering graphics and performing parallel processing tasks, not for storage. In contrast, RAM, SSD, and ROM are all types of computer storage.

Which is an example of a serif font?

• Wing Dings

• Arial

• Helvetica

• Times New Roman

Answer explanation

Helvetica & Arial are both sans serif fonts, which means they DON'T have any cursive extra bits like tails and feet. Wing dings is a picture font, like emojis.

Realistic human motion is required for a 3D animation. Which of the following techniques would be the most useful in helping to develop this aspect of the film?

• Modelling

• Motion Capture

• Rigging

• Tweening

Answer explanation

Motion capture films live action and translates it into digitised movement.

What is one of the STANDARD frame rates for video?

• 8

• 12

• 24

• 60

Answer explanation

24, 25, & approximately 30 are all standard frame rates. 12 fps can be used for stop-motion animation, while 60, 120, & 240 fps can be used for slow-motion filming.

What is the audio format that stores digital notations of a music track?

• AIFF

• AAC

• MIDI

• MP3

Answer explanation

Musical Instrument Digital Interface (MIDI) is where the notes are recorded, rather than the sounds. It allows for much smaller files and for the swapping of one instrument for another.

Which of the following will affect the file size of an image?

• colour depth

• hard drive space

• processor speed

• the size of your screen

Answer explanation

The size of an image (in bits) = resolution x colour depth (or bit depth)

In what type of animation is tweening used?

• Cel-based

• Path-based

• Still-based

• Stop-based

Answer explanation

Cel-based is frame-by-frame animation, whereas path-based requires the user to create keyframes and the program fills in the in between frames, a process known as tweening.

How does lossless audio compression reduce file size?

• By using algorithms.

• By lowering bit depth.

• By reducing the sample rate.

• By changing bit rates.

Answer explanation

Lowering any information settings will result in lossy compression, that is the file loses data. Lossless occurs through identifying and consolidating areas of "sameness".

What unit of measurement is used to determine the sample rate of a digital sound file?

• bytes

• decibels

• kHz

• Mb/sec

Answer explanation

Hertz is a measure of how many slices (or samples) are taken of a sound per second.
