An alternative to hexadecimal notation for representing bit patterns is dotted decimal notation in which each byte in the pattern is represented by its base ten equivalent. In turn, these byte representations are separated by periods. For example, 12.5 represents the pattern 0000110000000101 (the byte00001100 is represented by 12, and 00000101 is represented by 5), and the pattern 100010000001000000000111 is represented by 136.16.7. Represent each of the following bit patterns in dotted decimal notation,
a. 0000111100001111 b. 001100110000000010000000c. 0000101010100000
Answer:
The program to this question as follows:
Program:
targetValue = 0.3333 #defining variable targetValue and assign value
sensorReading = 0.0 #defining variable sensorReading and assign value
sensorReading = 1.0/3.0 #calculate value in sensorReading variable
Val=sensorReading - targetValue
#calculate the difference and store in Val variable
if (Val < 0.0001): #use of if block to check condition
print ("Equal") #print value
else: #else block
print ("Not equal") #print value
Output:
Equal
Explanation:
In the above Python program code, there are two variables "targetValue and sensorReading" is defined, in which targetValue store a value, that is "0.3333", and sensorReading holds a value, that is "0.0".
- In the next step, the "Val" variable is defined, that calculate the difference between both variable, that conditional statement is used.
- In if block, if the value is less then "0.0001", it will print value "Equal", otherwise, it will go to the else block, that will print "Not equal".
Answer:
Port scanner
Explanation:
The penetration tester would most likely use a port scanner. A port scanner can be explained to be an application that is made to check a server or host for ports that are open. This application can also be used by administrators to check their security networks so as to know those network services that are running on a host and also to know existing vulnerabilities. Attackers also use this to exploit victims.
