When an attacker moves to a new machine and scans the network to look for machines not previously visible, the technique is called Network Scanning. This technique is used by hackers to identify targets in a network that are vulnerable to their attacks.
It is an automated process of gathering information about the hosts and the services running on them. It involves probing the network to find out what services are running, what operating system is running, and what vulnerabilities exist on the target machines.Network scanning techniques allow the attacker to gather information about the hosts that they are targeting. Some of the most common techniques include ping sweeps, port scans, and OS detection scans. Ping sweep involves sending an ICMP (Internet Control Message Protocol) packet to every host on the network to determine which hosts are active.Port scans are used to identify open ports on the target hosts.
These scans help hackers to determine what services are running on a machine, and what vulnerabilities might be present.OS detection scans are used to identify the operating system that is running on the target machine.
This information is useful to hackers because different operating systems have different vulnerabilities and security weaknesses. Once the attacker has identified vulnerable machines, they can then begin their attack using a variety of methods.

write a function named remove range that accepts three parameters: a set of integers, a minimum value, and a maximum value. the function should remove any values from the set that are between that minimum and maximum value, inclusive. for example, if a set named s contains {3, 17, -1, 4, 9, 2, 14}, the call of remove range(s, 1, 10) should modify s to store {17, -1, 14}.
Here is the code for the "remove_range" function:
```python
def remove_range(nums, min_val, max_val):
nums.difference_update(set(range(min_val, max_val+1)))
```
The "remove_range" function takes three parameters: "nums" (a set of integers), "min_val" (the minimum value), and "max_val" (the maximum value). The function uses the "difference_update" method to remove any values from the "nums" set that fall within the range defined by "min_val" and "max_val", inclusive.
The "range" function generates a sequence of numbers from "min_val" to "max_val+1" (since the end value is exclusive in the range function). By converting this sequence to a set, we can easily determine which values need to be removed from the original set.
The "difference_update" method modifies the original set by removing any common elements between the set generated from the range and the original set "nums". In other words, it removes the values that fall within the specified range.
The code uses the "+1" in the range function to include the maximum value in the range. For example, if the range is defined as (1, 10), it will include both 1 and 10 in the range. If we only used "max_val" in the range function, the maximum value would be excluded.

What is programming?Computer programming is the process of performing specific computations, typically through the design and development of executable computer programmes.
Here is the implementation of the BloodData class as described:
public class BloodData {
private String bloodType;
private char rhFactor;
public BloodData() {
this.bloodType = "O";
this.rhFactor = '+';
}
public BloodData(String bloodType, char rhFactor) {
this.bloodType = bloodType;
this.rhFactor = rhFactor;
}
public String getBloodType() {
return bloodType;
}
public char getRhFactor() {
return rhFactor;
}
public void setBloodType(String bloodType) {
this.bloodType = bloodType;
}
public void setRhFactor(char rhFactor) {
this.rhFactor = rhFactor;
}
}
Thus, this implementation demonstrates the creation of BloodData objects with default and custom values.

sequential is a type of ________blank structure in which one program statement follows another.
It is incorrect to say that one program statement follows another program statement in a sequential structure. A REPEAT or LOOP STRUCTURE describes a process that can be repeated as long as certain conditions are met.
What kind of structure is sequential?A sequential structure shows the order of a process, sequence of steps, or events.
Is Do While an example of a sequential structure?Yes DO WHILE is used as a sequential structure. Reports at the end of the program design step usually consist of pseudocode, flow charts, and logical structures. Coding is just one of the six programming steps.
What distinguishes case structure and sequence structure?Unlike sequence structs, case structs can pass data and exit the while loop at any time. For example, if an error occurs while executing the first test, the Case structure can pass FALSE to the conditional terminal to exit the loop.

A language is considered to be ____ when format has no effect on the program structure (other than to satisfy the principle of longest substring).
A language is considered context-free if the format has no effect on the program structure (other than to satisfy the principle of the longest substring).
Context-free languages can be expressed as a context-free grammar, which is a formal language that can be used to define languages that are not context-free. A context-free language is a language that can be created by starting with a symbol called the start symbol, then using a set of rules to replace symbols with strings of symbols.
In contrast, regular languages, which are a subset of context-free languages, can be defined by a set of rules or expressions that only include basic operations such as concatenation, union, and closure. A language is said to be context-free if it can be generated by a context-free grammar. Therefore, the main answer is context-free.

the use of generic methods and classes have two primary primary advantages over code that is written to simply use object references for the data type instead. describe these two significant advantages.
Generics are a vital tool for developers because they help them create more dependable, efficient, and readable code.
What is the use of generic methods ?The first key benefit of utilising generics in coding is that it makes the code more efficient and reliable by enabling the usage of more complicated data types without the requirement for pointless type-casting.Because the compiler can now automatically identify type mismatches, the code is more robust and less likely to produce mistakes. Since the same code can be used for several data types, employing generics also makes the code easier to maintain and reuse.Better readability and clarity is the second benefit of employing generics. Generics make the code more evocative and understandable, which helps engineers spot and troubleshoot issues more quickly.The code is already built to be generic and self-documenting, so this improved readability makes it simpler to adapt it for other data types as needed.Generics are a useful tool for developers, enabling them to create more reliable, effective, and readably structured code.

A possible solution to a laptop whose global positioning system (GPS) is not functioning is to: verify that airplane mode is not activated on the laptop.
A laptop can be defined as a small, portable computer that is embedded with a keyboard and monitor, which is light enough in terms of weight, to be placed on the user's lap while working.
Assuming, the technician has verified that all the wireless settings on the laptop are correct.
Hence, the most likely problem for the laptop's global positioning system (GPS) not to function is that it is in airplane mode.
Generally, when an airplane mode is activated (turned on) on a laptop, all the software programs that uses wireless technology would not function, until it is disabled (turned off)
In conclusion, a possible solution to a laptop whose global positioning system (GPS) is not functioning is to verify that airplane mode is not activated (turned on) on the laptop.
