Answer:
<em>a. fetch</em>
Explanation:
<em>The device collects a program command from its memory during the run cycle of the fetch.
</em>
It then defines and performs the activities needed for that command. The CPU continuously repeats the cycle of fetching, decoding, and executing a command while the computer is switched on.
Answer:
B. The storage structure requires a clock input.
Explanation:
Logic circuits are circuits in electronics that give output based on the logic gate principle and its inputs. It can be a sequential logic circuit or a combinational logic circuit.
Decoders RS latches are combinational logic circuits because they both comprise of a combination of several sequential circuits to make their systems. The difference between decoders and RS latches is that the RS is a storage structure which is made up of flip-flops which require a clock input
Answer:
Enter a number: 7
Enter a number: 10
Traceback (most recent call last):
File "main.py", line 3, in <module>
print (numi + num2)
NameError: name 'numi' is not defined
Explanation:
The typo in the print statement causes a run-time error, where obviously num1+num2 was expected, and an output of 17.
<em>Intrusion means unauthorized and harmful activities happening in your system. Any irregularities in the system is considered as intrusion and therefore monitored by administrators and can be detected using Intrusion Detection System.
</em>
<em>Examples of Intrusion attacks in a network are:
</em>
- <em>Denial of Service (Dos) - denial of service means flooding the system causing it to crash and unable to respond to a service request. Normally, a DoS attack is facilitated by numbers of hosts sending enormous request to a victim computer. The requests can be in a form of code that would flood the system and making it to unresponsive. </em>
- <em>Man in the Middle Attack (MiM) - a hacker would be in the middle of the communication between a client computer and a server computer. The hacker can mimic IPs within the network and steal information then sends it to the intended receiver. </em>
- <em>SQL Injection - For websites that runs database like SQL, a code by the hacker can be added to the website and making him gained access to the database information successfully.</em>
