Multiple answers. Attachment and practice of sending unwanted messages
<em>Hey there!</em>
Just to be corny, what does a spider use to navigate the internet? <em>The World Wide Web! </em>Did you catch that? Hopefully you did...
Anyway, enough with my jokes, here's your answer.
Transmitting information through computers are cheap and fast because of multiple things. The first reason is because they don't require a deliverer or shipping. They can literally be sent from anywhere and be delivered within 10 seconds-5 minutes, way faster than any mailman or delivery. How does it move that fast? Smaller files tend to move quicker among the invisible online delivery lines, most commonly known as cell towers. To get online info from your phone/computer to someone else's device, the file bounces from tower to tower to finally reach the destination.

Signal processing deals with the analysis and operation of a. mechanical signals b. electrical signals c. biological signals. These can be b. digital c. analog which vary across a range of values or b. digital with only two possible values.
Explanation:
- In signal processing, a signal is a function that conveys information about a phenomenon. In electronics and telecommunications, it refers to any time varying voltage, current or electromagnetic wave that carries information.
- A signal may also be defined as an observable change in a quality such as quantity...
- A signal can be audio, video, speech, image, sonar and radar-related
- Signal processing deals with the analysis and operation of mechanical signals, electrical signals and biological signals.
- The value of the signal is an electric potential which is voltage is also a signal.
- The term analog signal usually refers to electrical signals. Analog signals may also be other mediums such as mechanical, pneumatic or hydraulic.
- An analog signal signifies a continuous signal that keeps changes with a time period. A digital signal signifies a discrete signal that carries binary data and has discrete values. Analog signals are continuous sine waves. Digital signal is square waves
