2. analog~ computer

3. analog~ record player

1. digital~ cd

2. digital~ clock

3. digital~ smartphones

3 differences between analog and digital signals

1. analog: could be any number, including infinity.

digital: any two numbers, besides infinity. for example: 8,987,964,123 and 18.

2. analog: continuous signal with physical increments (like a record player)

digital: individual signals marked digitally (like a cd)

3. analog: can hold limited amounts of data

digital: lots of space to hold information (take an iPhone for example)

3 differences between analog and digital technology

1. analog technology is not as good quality, as to where digital is much better.

2. analog is shown in shades of gray, and digital is many different colors.

3. analog works slower, where as digital moves and transitions much faster

3 reasons why I prefer digital over analog

1. digital is more space efficient, because its usually smaller and takes up more space than an analog device typically would (cd vs. record player for example)

2. analog technologies are harder to find in our generation, because they are considered to be old school. And since they are harder to find because their older, analog costs more. Therefore digital is the cheaper, easier to find, and the better more advanced technology.

3. Digital usually has better quality than analog, like better quality sound in a cd player vs. a cassette tape.
