Answer:

Passive security attack are the unauthorized disclosure in the network attack. In this type of security attack a system are use for monitoring and sometimes scanning the open port. It basically include the monitoring the unprotected data and traffic analysis.

On the other hand, active security system modify the transmitted data and gain the unauthorized access from the computer system.

This type of security attack basically monitor the file transfer and electronic mail from the attacks which can be pass in the form of viruses in the computer system.

Hope this helps.

Develop an sec (single error correction) code for a 16-bit data word. generate the code for the data word 0101000000111001. show

Kipish [7]

Answer:

code = 010100000001101000101

Explanation:

Steps:

The inequality yields $2^{k} - 1 > = M+K$ , where M = 16. Therefore,

The second step will be to arrange the data bits and check the bits. This will be as follows:

Bit position number Check bits Data Bits

21 10101

20 10100

The bits are checked up to bit position 1

Thus, the code is 010100000001101000101

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)
