Answer:
An assembler.
Explanation:
Input is (as with any programming language) files with lists of instructions (typically assembler mnemonics), output is a binary format representing these instructions in machine language.
I'd go with command-line interface.
A CLI enables users to type commands in a console or a terminal window expressed as a sequence of characters and presses the enter key on the keyboard to execute that command. And in this case, Sarah is typing an “open document 3” command to the command-line interface to open a file in her computer.
Answer:
graph screen is the correct answer
Digital vs Analog Audio is completely personal preference and there is no clear winner on which is better.
But there are some pros and cons about both, Analog sometimes distorts when playing and can be easily scratched and ruins the grooves. Analog is believed to be the true representation of the sound when it was recorded. Digital is not the actual recording of the sound, it's actually a combination of binary code. It is also sometimes mixed or remastered in Digital and sounds a bit different to make it sound better. It also depends on the system you are listening it from. You could have a horrible Digital system its playing through and an amazing Analog system playing, of course the Analog system will sound better in that case. Some believe that Digital is on par to overtake Analog in the "true picture of sound" category but some also say Analog will forever be the best at playing sound and Digital will always be the alternative.
But, in the end it's all personal preference and the pros and cons don't overweigh to make one better than the other.
