|
What is compilation error? |
Compilation error - error in the syntax of the code which why the program will not compile
|
|
|
What Run-time error? |
Run-time error - error in the program during run-time E.g. invalid user input |
|
|
What is Logic error? |
Logic error - error in the outcome of the program. The programmer may have wanted it to do one thing and it did something else |
|
|
What is sampling resolution? |
Sampling resolution - number of bits used to sample the data
|
|
|
What is a fixed value variables |
Fixed value - a variable in which its value does not change - stays fixed throughout the whole program |
|
|
What is a Stepper variable? |
Stepper - a variable which is used to count the number iterations of a loop during a program
|
|
|
What is a most recent holder variable? |
Most recent holder - a variable which is the most recent one out of many other variables |
|
|
What is a Follower variable? |
Follower - a variable which takes the value of another variable
|
|
|
What is Gatherer variable? |
Gatherer - a variable used to calculate the sum of something |
|
|
What is MIDI? |
MIDI:
- Uses digital media to replicate the sounds of an instruments. It can be used to change the key, instruments ect.
|
|
|
What is advantage of MIDI? |
Advantage of MIDI - compact form of holding the digital data and can manipulate the data easily by changing the instrument or key |
|
|
What a Streaming audio? |
Streaming audio allows a client to listen to an audio without having the wait for the whole sound file to load. The client can start listening to the audio as soon as the buffer fills with audio but when the buffer runs out of the audio data - the client has to wait for the buffer to fill again to be able to listen to it. This saves a lot of time because the buffer can fill while the client listens to the audio file |

|
Describe how a vector graphics program stores the data about the image? |
Mathematical formulae are used to recreate the vector graphics and objects, like circles and triangles are used from a list of drawing commands |
|
|
What are the properties of an object |
Properties of an object - increase radius, uses a fill colour of an object.
|
|
|
Why do programs have procedures/functions?
|
Programs have procedures and functions as its easier to debug, test, don't have to repeat lines of code throughout the program and it encourages the uses
|
|
|
|
Gray code is better than binary because Gray code counters use less electrical power and there are fewer errors because only one output bit changes at a time so we would know if there is a mistake if more than one bit change at a time |
|
|
Why is Vector graphics better than bit map? |
Vector graphic usually store the image with a lower number of bytes. Vector graphics do not become distorted when they are scaled unlike bitmaps because they do not have pixels. |
|
|
What is the advantage of using a constant instead of named variables? |
Advantage of using constants instead of named variables for fixed values because you can just change one value and the value can be use and will change throughout the program |
