We use analog and digital signals in our everyday lives with the radio, the cell phone and with our own computers. our computers and our cell phones are all digital now but radio's are still considered analog. Radio telescopes explore space by using radio waves and signals to almost like scan space and collect data like a sonar in a submarine.

Radio telescopes are specialized “antenna” and a “radio receiver”. This is used to receive radio waves. It observes space by receiving radio signals.

Analog signal transmit data in the form of wave

Digital signal will be in the form of ones and zeros. High value represents 1 and low value represents 0. It is like on and off switch.

Eg.

Analog signal & Digital signal:

Aneriod barometer

digital signature

Digital photography

Digital Satellite system

Digital television

Cell phones

Analog computer

When you're working with a word processing document and you press the del key, what happens?
Svetach [21]

The <DEL> or <Delete> key makes the first character AFTER the cursor
disappear, and everything after it then moves back one space to close up
the hole.

Example: 

If I have this in my document ...                          Most trees are green.

And my cursor is after the 'a', like this:                Most trees a|re green.

Now, if I hit the <delete> key, it deletes the
'r' after the cursor, and the hole closes up,
and the cursor stays where it is:                          Most trees a|e green.

Write a program that prompts the user to enter a series of numbers between 0 and 10 asintegers. The user will enter all numbers
Anna71 [15]

Answer:

The program in Python is as follows:

import collections

from collections import Counter

from itertools import groupby

import statistics

str_input = input("Enter a series of numbers separated by space: ")

num_input = str_input.split(" ")

numList = []

for num in num_input:

         if(num.lstrip('-').isdigit()):

                   if num[0] == "-" or int(num)>10:

                             print(num," is out of bound - rejecting")

                   else:

                             print(num," is valid - accepting")

                             numList.append(int(num))

         else:

                   print(num," is not a number")

print("Largest number: ",max(numList))

print("Smallest number: ",min(numList))

print("Range: ",(max(numList) - min(numList)))

print("Mode: ",end = " ")

freqs = groupby(Counter(numList).most_common(), lambda x:x[1])

print([val for val,count in next(freqs)[1]])

count_freq = {}

count_freq = collections.Counter(numList)

for item in count_freq:

         print(item, end = " ")

         lent= int(count_freq[item])

         for i in range(lent):

                   print("#",end=" ")

print()

Explanation:

See attachment for program source file where comments are used as explanation. (Lines that begin with # are comments)

The frequency polygon is printed using #'s to represent the frequency of each list element
