Aisolates
Bignores
Cblocks
Dconnects
Attempts:

💡 Hint
Common Mistakes
Choosing 'isolates' because it sounds like separation, but the bus matrix enables connection.
Selecting 'blocks' or 'ignores' which prevent access, opposite of the bus matrix's role.
2fill in blank
medium

Complete the sentence to explain how a bus matrix handles simultaneous requests.

ARM Architecture
When multiple masters request access at the same time, the bus matrix [1] these requests to avoid conflicts.

💡 Hint
Common Mistakes
Choosing 'ignores' which would cause some requests to be lost.
Selecting 'duplicates' which would cause errors by repeating requests.
