Answers
A sensor is used at traffic lights to identify the presence of automobiles. Either a closed loop or an open loop can exist.
How do open and closed loops differ?
An open-loop control system, commonly referred to as a non-feedback system, solely bases its actions on the input; the control action is unaffected by the output. A closed-loop control system, commonly referred to by the term review system, examines the power capacity and modifies it to produce the desired condition.
What distinguishes an open loop from a closed loop?
The open network and a closed loop system are fundamentally different from one another in that the former can self-correct while the latter cannot. As a result, components are quite often known as non-feedback controls, whereas closed-loop systems are frequently referred to as feedback-controlled systems.

Consider the following recursive algorithm: (a) Prove that Algorithm Weirdsort correctly sorts the elements in the array A. 2 (b) Ignoring ceilings (i.e. we can assume that n is a power of 3 ), write the recurrence in terms of n describing how many calls are made to Weirdsort with an initial call of Weirdsort (A[0…n−1]) ? Hint: write a recurrence whose general form is R(n)= aR(n/b)+f(n) where a,b are rational numbers and f(n) is a function of n. Justify why your recurrence is counting the number of recursive calls. (c) Using this recurrence, prove that R(n) is at most n 3
when n≥2 using induction.
Answers
(a) To prove that Algorithm Weirdsort correctly sorts the elements in the array A, we need to show two things: (1) it terminates and (2) it produces a sorted array. For termination, the algorithm works by repeatedly dividing the array into three equal-sized subarrays and recursively calling itself on each subarray. 1.termination is guaranteed. To show that the algorithm produces a sorted array, we need to prove the correctness of the recursive calls. Let's assume that the Weirdsort algorithm works correctly for arrays of size less than n. Then, we can say that for any array of size n, the algorithm will correctly sort it by recursively sorting the subarrays.
(b) R(n) = 3R(n/3) + f(n) In this recurrence relation, n represents the size of the array and R(n) represents the number of recursive calls made to Weirdsort. The term 3R(n/3) accounts for the three recursive calls made on the three subarrays of size n/3 each. The term f(n) represents any additional operations or calls made outside of the recursive calls.
The recurrence relation accurately counts the number of recursive calls because for each recursive call, the size of the array is divided by 3. The initial call is made on an array of size n, and subsequent calls are made on subarrays of size n/3, n/9, n/27, and so on, until the base case of size 1 is reached.
(c) To prove that R(n) is at most n^3 when n≥2 using induction, we need to show two things: (1) the base case and (2) the inductive step. Base case: For n=2, we have R(2) = 3R(2/3) + f(2). Since n=2, the size of the array is reduced to 2/3 in the recursive call. Therefore, R(2/3) is the number of recursive calls made on an array of size 2/3. Since n<2, the base case holds. Inductive step: Assume that R(k) ≤ k^3 for all k.

the performance of a CPU scheduling algorithm depends on various factors such as the nature of the workload, the size of the processes, and the system configuration. However, some commonly used scheduling algorithms are First Come First Serve (FCFS), Shortest Job First (SJF), Round Robin (RR), and Priority-based scheduling.
In general, the SJF algorithm tends to perform best when the processes have similar arrival times and vary significantly in their execution times. This is because the SJF algorithm prioritizes the shortest jobs first, resulting in lower average waiting and turnaround times. However, if the processes have similar execution times and the system requires responsiveness, the RR algorithm might perform better as it allows for quick switching between processes, providing a fair share of CPU time to each process and ensuring responsiveness. Overall, the choice of scheduling algorithm depends on the specific requirements of the system, and a combination of different algorithms may be used to optimize the system's performance.

Using the RSA encryption algorithm, pick p = 11 and q = 7. Find a set of encryption/decryption keys e and d
Answers
To find a set of encryption/decryption keys e and d using the RSA encryption algorithm with p = 11 and q = 7, we need to follow these steps:
Step 1: Calculate n
n = p * q
n = 11 * 7
n = 77
Step 2: Calculate the totient of n (phi)
phi(n) = (p - 1) * (q - 1)
phi(n) = 10 * 6
phi(n) = 60
Step 3: Choose an integer e such that 1 < e < phi(n) and gcd(e, phi(n)) = 1
Let's choose e = 7
Step 4: Calculate d such that (d * e) mod phi(n) = 1
To find d, we can use the extended Euclidean algorithm:
phi(n) = 60
e = 7
60 = 8 * 7 + 4
7 = 1 * 4 + 3
4 = 1 * 3 + 1
1 = 4 - 1 * 3
1 = 4 - 1 * (7 - 1 * 4)
1 = 2 * 4 - 1 * 7
1 = 2 * (60 - 8 * 7) - 1 * 7
1 = 2 * 60 - 17 * 7
d = -17
Since d is negative, we can add phi(n) to it to get a positive value:
d = 43
Therefore, the set of encryption/decryption keys for p = 11 and q = 7 is (e=7, d=43).

What is a ERM Program?
Enterprise risk management (ERM) is a concept that looks at risk management strategically from the perspective of the entire business or organisation. The objective of this top-down strategy is to identify, assess, and prepare for potential losses, dangers, hazards, and other potential sources of harm that could hinder an organization's operations and goals and/or lead to losses.
Enterprise risk management calls for management-level decisions that may not be appropriate for all business units or market sectors when using a comprehensive approach. As a result, corporate oversight takes precedence over the accountability of each business unit for its own risk management.

We are trying to protect a household computer. We have implemented password-based authentication to protect sensitive data. Which levels of attacker motivation can this authentication typically protect against in this situation
Answers
Password-based authentication can typically protect against attackers with low to moderate levels of motivation. In the case of a household computer, the primary concern is typically unauthorized access by individuals who may have physical access to the computer, such as family members, friends, or visitors.
Password-based authentication can effectively deter casual attackers with low motivation, such as curious family members or friends, who may attempt to access the computer out of curiosity or without malicious intent. It can also provide a basic level of protection against attackers with moderate motivation, such as individuals who may want to access sensitive personal information, steal data or engage in identity theft.
However, it is important to note that password-based authentication may not be sufficient to protect against attackers with high levels of motivation, such as professional hackers or cybercriminals who are well-versed in hacking techniques and have the resources and skills to crack passwords or bypass authentication measures. These attackers may use advanced techniques such as phishing, social engineering, or brute-force attacks to gain access to the computer or steal sensitive data.
Therefore, it is important to complement password-based authentication with other security measures such as regular software updates, anti-virus software, and firewall protection, as well as following best practices such as avoiding suspicious links, using strong passwords, and keeping sensitive information encrypted.

which port should be filtered (or blocked) to disallow netbios traffic?
Answers
To disallow NetBIOS (Network Basic Input/Output System) traffic, you should filter or block the port: Port 137 (UDP)
NetBIOS operates primarily over UDP (User Datagram Protocol) on port 137. This port is used for NetBIOS name service, which is responsible for name resolution and identification of devices on a network. Blocking or filtering port 137 effectively restricts NetBIOS traffic from passing through the network.
NetBIOS is an older networking protocol primarily used in Windows-based systems for sharing files, printers, and other resources. It operates at the session layer of the OSI model and has been largely replaced by more modern protocols such as SMB (Server Message Block) in newer Windows versions.
Blocking or filtering port 137 prevents NetBIOS traffic from traversing the network, helping to enhance security and reduce potential vulnerabilities associated with the protocol. It can also prevent certain types of network-based attacks and reduce network congestion caused by unnecessary NetBIOS traffic.
Implementing port filtering or blocking can be done using various network security mechanisms such as firewalls, access control lists (ACLs), or other network devices capable of enforcing traffic restrictions. Configuring these devices to block inbound and outbound traffic on port 137 effectively disallows NetBIOS traffic in the network.
