What is the issue with the continuation line in regards to visual indentation?
Multiple choices:
A) The continuation line is indented too much
B) The continuation line is not indented enough
C) The continuation line is indented correctly
D) The indentation of the continuation line depends on the programming language used
A) The continuation line is indented too much. The continuation line is used when a line of code is too long to fit in a single line and needs to be continued on the next line.
The issue with the continuation line in regards to visual indentation is that it is often indented too much, making the code difficult to read and understand. Over-indentation of the continuation line can make the code look cluttered, and can make it hard to see the overall structure of the code.
To avoid this issue, it is important to follow the correct indentation rules for the programming language being used. In some programming languages, the continuation line is indented with a fixed number of spaces or tabs, while in others, it depends on the context of the code. Proper indentation can make the code more readable and easier to understand, improving its overall quality.

A malicious user launches in attack on a private network, and believe the attack has been successful. However, the target not work is not compromise. What security measure is it most likely using
This private network was successfully attacked but the target system has not been compromised. This indicates that the network is likely using an effective security measure to protect itself.
The most probable security controls in place would be:
Firewall: A firewall acts as a barrier between the private network and outside threats. It is inspecting traffic and blocking malicious access attempts. This is the most likely security measure preventing the attack from reaching its target.VPN: Using a virtual private network adds an extra layer of encryption and security over the network. Only authorized users with VPN access would be able to connect to the private network, shielding it from outsiders.Endpoint protection: Software like antivirus, anti-malware, and intrusion prevention systems installed on network devices and systems. These provide real-time scanning and can detect/block the attack before it infiltrates endpoints.Network monitoring: Tools are in place to actively monitor network activity, Ethernet/Wi-Fi connections, device communications, etc. Abnormal behavior would immediately flag the attack for inspection.User authentication: Strong password requirements, multi-factor authentication, biometrics or other verification ensures only authorized users can access the private network and systems. Attacker access was blocked at the login stage.In summary, the network is protected using a combination of controls like firewalls, VPN, endpoint security, monitoring and authentication. No single measure alone would prevent every attack, but together they are able to stop even sophisticated threats from compromising the network.

What must an application know to make a socket connection in software?
An application must know the destination IP address, destination port number, and the protocol (TCP or UDP) to make a socket connection in software.
To make a socket connection, an application needs the following information:
1. Destination IP address: This is the unique address of the device (host) with which the application wants to establish a connection. The IP address can be in IPv4 or IPv6 format.
2. Destination port number: This is a 16-bit number that identifies a specific process or service running on the destination host. Some well-known port numbers are 80 for HTTP, 443 for HTTPS, and 21 for FTP.
3. Protocol (TCP or UDP): The application must also specify the protocol to be used for the socket connection. TCP (Transmission Control Protocol) is a reliable, connection-oriented protocol, while UDP (User Datagram Protocol) is a connectionless, unreliable protocol. The choice depends on the application's requirements for reliability and speed.
By providing this information, an application can establish a socket connection and exchange data with another device or process running on the destination host.

what database does a router consult before determining the most efficient path for delivering a message?
A router consults the routing table or routing information base (RIB) in order to determine the most efficient path for delivering a message. The routing table is a database of information that contains information about the available paths for sending data packets to their destination.
The routing table is typically maintained by the router's routing protocol, which is responsible for learning about the network topology and exchanging routing information with other routers. The routing protocol updates the routing table with the most up-to-date information about network topology and the availability of different paths.When a router receives a message, it consults the routing table to determine the best path for delivering the message to its destination. The routing table contains information such as the network address of the destination, the next hop router that the message should be sent to, and the cost or metric associated with each available path.

Applying what we know about Referential Transparency, is the following true? An RT function should be so reliable that you could replace the function with the value it returns and not change the outcome of the program. IE: instead of having f(2) everywhere you would just replace f(2) with what was calculated. a. True b. False
Applying what we know about Referential Transparency, it is true that an RT function should be so reliable that you could replace the function with the value it returns and not change the outcome of the program. The correct answer is option a) True.
Referential transparency is a functional programming concept in which an expression or function always produces the same result for a given input value. A function with referential transparency doesn't depend on the state of the system or anything other than the input passed in. It is defined solely by its input-output relationship. Pure functions are also referentially transparent because they don't depend on anything other than their inputs.
For example, consider the following function: const add = (a, b) => a + b; This function is referentially transparent because no matter how many times you call it with the same arguments, you'll always get the same result. That is, adding (2, 3) will always equal 5. The main advantage of referential transparency is that it allows code to be composed more easily. Because the output of a function is solely determined by its inputs, it can be substituted for any other expression that has the same output for the same input.
