2 answers:

8 0

A modem is the internal or external device its function is to transfer data over communication lines
modems use two different types of data transmission
synchronous and asynchronous
The functions of modem have changed over years it was first used for telegrams and to transmit data in 1950s.
Modems were used with computers in 1977 for first time to transmit data between computers firstly it was used for small amount of computers
As modem improves day by day and were able to transmit information fastly between two or more hosts and the internet network slowly spreads
There are four types of modems ,
1 Fax Modems which solely transfer data between fax machines
2 The traditional ISDN modem
3 the Digital Subscribers Line
4 the Cable Modem

A modem is an external and/or internal device thats function is to transmit digital data over communication lines. Traditional modems used frequently with dial-up networks to change analog data from telephone lines into computer digital data. Broadband modems transfer digital data between digital devices, specifically two.

1. Separate valid and invalid variables:

DedPeter [7]

Firstly we explain the variable and the declaration rule for the variable and further separating the valid and invalid variables.

Whenever a user is given a question, variables are data values that can vary. for example age, CSL, etc.
It may alter and during the execution of the program.
It's a storage space for memories.
It has a name that corresponds to the location.
Data is stored in the memory location.

The rule for variable declaration:

The names of your variables should be based on the phrases used in the subject area, and they should reflect the variable's function.
By removing spaces between the words, you can make variable names. Each word in the name should be capitalized, including prepositions and pronouns that are one letter long.
An underscore should never be used to start a variable name.
Single-character variable names should be avoided. For loop counters, only short variable names are permitted.
After the state that equals the "true" value, name variables that describe binary states ("true" or "false").

The valid variable is:

CSL, Age,CLS,SEE,Stop5for,Give, $shopping, and United.

The invalid variable is:

Mark-sheet, Tel $, Simple Interest, and 545Newton.

Determine whether the compound condition is True or False.

Vlada [557]

The compound condition are:

7<12 or 50!=10 is false
7<12 and 50<50 is false
not (8==3) is true

<h3>What is compound condition?</h3>

A compound statement is known to be one that shows up as the body of another statement, e.g. as in if statement.

The compound condition are:

7<12 or 50!=10 is false
7<12 and 50<50 is false
not (8==3) is true

Write a program with 2 separate functions which compute the GCD (Greatest Common Denominator) and the LCM (Lowest Common Multipl

Maru [420]

Answer:

The program written in Python is as follows

def GCD(num1, num2):

small = num1

if num1 > num2:

small = num2

for i in range(1, small+1):

if((num1 % i == 0) and (num2 % i == 0)):

gcd = i

print("The GCD is "+ str(gcd))

def LCM(num1,num2):

big = num2

if num1 > num2:

big = num1

while(True):

if((big % num1 == 0) and (big % num2 == 0)):

lcm = big

break

big = big+1

print("The LCM is "+ str(lcm))

print("Enter two numbers: ")

num1 = int(input(": "))

num2 = int(input(": "))

GCD(num1, num2)

LCM(num1, num2)

Explanation:

This line defines the GCD function

def GCD(num1, num2):

This line initializes variable small to num1

small = num1

This line checks if num2 is less than num1, if yes: num2 is assigned to variable small

if num1 > num2:

small = num2

The following iteration determines the GCD of num1 and num2

for i in range(1, small+1):

if((num1 % i == 0) and (num2 % i == 0)):

gcd = i

This line prints the GCD

print("The GCD is "+ str(gcd))

This line defines the LCM function

def LCM(num1,num2):

This line initializes variable big to num2

big = num2

This line checks if num1 is greater than num2, if yes: num1 is assigned to variable big

if num1 > num2:

big = num1

The following iteration continues while the LCM has not been gotten.

while(True):

This if statement determines the LCM using modulo operator

if((big % num1 == 0) and (big % num2 == 0)):

lcm = big

break

big = big+1

This line prints the LCM of the two numbers

print("The LCM is "+ str(lcm))

The main starts here

This line prompts user for two numbers

print("Enter two numbers: ")

The next two lines get user inputs

num1 = int(input(": "))

num2 = int(input(": "))

This calls the GCD function

GCD(num1, num2)

This calls the LCM function

LCM(num1, num2)
