Each Class C IP address supports up to 254 host computers.

Each device connecting to the internet is given an individual identity known as an IP address. Class C is one of the many classes of IP addresses. Class C addresses only include an 8-bit host part since they have a 24-bit network prefix. The host part of the address has 8 bits in binary, giving rise to 256 potential permutations. There are only 254 addresses available for hosts since two of these combinations are set aside for the network address and broadcast address. As a result, 254 host computers can use a Class C IP address. This qualifies it for small- to medium-sized networks, including those in residences, startups, and educational institutions. For bigger networks, such those in businesses or In academic institutions, Class B or Class A addresses may be utilised to support more hosts.

The given statement "In general, a variable name must begin with either a letter or an underscore(_)" is true because, in most programming languages, a variable name must begin with either a letter or an underscore (_).

This is because variables are used to represent values in the program, and their names should be descriptive and easy to understand. In addition, variable names may not include spaces or special characters with the exception of the underscore character.

Variable names should also be case-sensitive, meaning that uppercase and lowercase letters are treated as distinct. By following these conventions, programmers can create variable names that are easy to read and understand, which can improve the readability and maintainability of their code.

Java provides a mechanism known as variable-length argument lists, which makes it possible to write a method that takes a variable number of arguments.

Java provides a mechanism known as "variable-length argument lists", which makes it possible to write a method that takes a variable number of arguments. This allows for flexibility in the number of arguments that can be passed to the method, making it more adaptable to different use cases. This feature is supported by the use of "polymorphic byte codes" in the Java Virtual Machine, which allows for efficient handling of methods with varying numbers of arguments.Variable-length arguments, abbreviated as varargs, are defined as arguments that can also accept an unlimited amount of data as input. The developer doesn't have to wrap the data in a list or any other sequence while using them.A method with variable length arguments(Varargs) in Java can have zero or multiple arguments. Variable length arguments are most useful when the number of arguments to be passed to the method is not known beforehand. They also reduce the code as overloaded methods are not required.

ARP Spoofing is a technique used by attackers to send fake Address Resolution Protocol (ARP) messages to other hosts in the Local Area Network (LAN).

The main objective of this attack is to associate the IP addresses of the victim's computer to the wrong Media Access Control (MAC) addresses. By doing this, the attacker can intercept the data packets meant for the victim's computer and redirect them to their own computer, which allows them to monitor, steal, or manipulate the data transmitted over the network.

To perform an ARP Spoofing attack, the attacker sends fake ARP messages to the LAN, which associates their MAC address with the IP address of the victim's computer. Once the attacker's MAC address is associated with the victim's IP address, the attacker can intercept the victim's network traffic by pretending to be the victim's computer.

To prevent ARP Spoofing attacks, network administrators can implement several measures such as using secure ARP protocols, monitoring network traffic for suspicious activities, and using network intrusion detection and prevention systems. It is also recommended to keep software and operating systems up-to-date to reduce the chances of successful ARP Spoofing attacks.

A switch may record multiple entries for a single switch port in its MAC address table in the following scenarios:

Multiple devices are connected to the same switch port: If a hub or switch is connected to a switch port, and multiple devices are connected to that hub or switch, then the switch will learn the MAC addresses of all those devices and record them against the same switch port in its MAC address table.

Virtual local area network (VLAN) tagging: If VLAN tagging is enabled on the switch port, then the switch may learn multiple MAC addresses associated with different VLANs on the same switch port.

Port channeling or link aggregation: If multiple physical links are aggregated into a single logical link using link aggregation or port channeling, then the switch may learn multiple MAC addresses associated with that logical link, and record them against the same switch port in its MAC address table.

In all these cases, the switch maintains separate entries for each MAC address learned on the same switch port, and uses this information to forward traffic to the appropriate destination.

Base addressing mode is a type of memory addressing mode where the address of the operand is calculated by adding a constant value (base) to the contents of a register. In other words, the base register holds a memory address that is used as a starting point for addressing operands.

Displacement addressing mode, on the other hand, involves adding a constant value (displacement) to the contents of a register to calculate the memory address of an operand. The displacement is usually a small value that is added to the contents of a register to point to a specific location in memory.

Offset addressing mode is a combination of base and displacement addressing modes, where the address of an operand is calculated by adding a constant value (displacement) to the contents of a register (base) and then accessing the memory location pointed to by the resulting address.

In summary, base, displacement, and offset addressing modes are all used to calculate the memory address of an operand in different ways. Base addressing mode uses a fixed starting point, displacement addressing mode adds a fixed value to a register, and offset addressing mode combines the two by adding a fixed value to a register that points to a starting point.

An instance member variable is a variable that is unique to each instance of a class,

Meaning that each object created from the class will have its own copy of the variable. On the other hand, a static member variable is a variable that is shared by all instances of a class, meaning that there is only one copy of the variable for all objects created from the class.

The main difference between the two types of variables is that instance member variables are specific to each object and can have different values, while static member variables are shared and have the same value across all objects.

The difference between an instance member variable and a static member variable can be described as follows:

1. Instance Member Variable: An instance member variable is associated with a specific instance of a class. Each object created from the class has its own copy of the instance variable, allowing it to store its own state. Instance member variables can only be accessed through an instance of the class.

2. Static Member Variable: A static member variable, on the other hand, is associated with the class itself, rather than with individual instances.

There is only one copy of a static variable, shared by all instances of the class. It can be accessed directly through the class name, without needing to create an object of the class.

In summary, the difference between the two lies in their association and accessibility. Instance member variables are tied to specific instances of a class, while static member variables are tied to the class itself and shared among all instances.

False. Acquiring a lock by one thread before accessing a shared memory location prevents other threads from being able to access the same shared memory location, even if the other threads do not acquire a lock.

Acquiring a lock by one thread before accessing a shared memory location ensures mutual exclusion and prevents other threads from accessing the same shared memory location simultaneously without a lock, but it does not prevent other threads from accessing the shared memory location if they acquire the same lock. In other words, the use of locks provides synchronization between threads and ensures that they don't access the shared memory location simultaneously, which can cause data inconsistencies and race conditions. However, other threads can still access the shared memory location if they acquire the same lock before accessing it.

The statement "Mutexes enforce an order among the threads" isTrue Mutexes are synchronization objects that are used to ensure that only one thread can access a shared resource at any given time.

When a thread acquires a mutex, it gains exclusive access to the resource, and other threads that attempt to acquire the same mutex will be blocked until the first thread releases it.

In addition to providing mutual exclusion, mutexes also enforce an order among the threads. When multiple threads are waiting to acquire a mutex, the order in which they are granted access is determined by the underlying operating system scheduler. This ensures that threads are given access to the resource in a predictable and orderly fashion, which can be important for ensuring the correctness and efficiency of concurrent programs.
