I need an explanation for this Computer Science question to help me study.
1. What is an analog signal? what is a digital signal? (min. 1 page long)
2. What is the relationship between data and the signal in the network physical layer? (min. 1 page long)
3. Data can be analog or digital. Analog data refers to continuous. Digital data are discrete. Signals can be either analog and digital. An analog signal has infinitely many levels of intensity over a period of time. A digital signal can have only a limited number of defined values, often as 0 and 1. Please understand these basic concepts and share your understanding.
Please submit at least 2.5 pages long. Thank you.
