A non-busy wait method used to handle tasks at rendezvous points is called a conditional synchronization.
This method works by having the tasks wait until the conditions for their continuance become true. This method is used because it allows for efficient use of resources. It avoids the constant checking of the condition, which is known as busy waiting, and instead allows the tasks to wait until the condition becomes true and then they can continue. The use of conditional synchronization also allows for tasks to be executed in parallel as the waiting tasks can be released as soon as the condition is met, making use of all available resources. Moreover, this method is not limited to rendezvous points, it can also be used for other synchronization tasks.

In C++, class is a reserved word and it defines only a data type. T/F?
True. In C++, the class keyword is used to define a new user-defined data type.
A class is essentially a blueprint or a template that defines the attributes and behaviors of a type of object. The class keyword is used to define a new class, which encapsulates data and functions that operate on that data.
Once a class is defined, you can create instances or objects of that class, which are actual instances of the class that have their own set of member variables and member functions. These objects can be created and manipulated in your code just like any other built-in data type.
It's important to note that class defines only a data type and doesn't create any objects or variables. To create an object of a class, you need to use the new keyword to allocate memory for the object on the heap, or declare an instance of the class on the stack.
In summary, class is a reserved keyword in C++ used to define a new user-defined data type that encapsulates data and functions that operate on that data. It doesn't create any objects or variables; instead, it defines a blueprint for creating them.

what is a set of numbers that represents each possible value or outcome in a computer simulation?
The set of numbers that represents each possible value or outcome in a computer simulation is known as the sample space.
The sample space is a fundamental concept in probability theory and statistics. It refers to the set of all possible outcomes that can occur in a given situation or event. In a computer simulation, the sample space is defined by the range of values that can be generated by the simulation model. These values can represent anything from the probability of an event occurring to the performance of a system under different conditions.
When designing a computer simulation, it is important to define the sample space accurately in order to obtain reliable results. This requires careful consideration of all possible outcomes that can occur, as well as the probability of each outcome. For example, if you are simulating the performance of a car engine, the sample space may include variables such as engine temperature, fuel consumption, and exhaust emissions. By defining the sample space in this way, you can generate a range of values for each variable and use statistical analysis to determine the most likely outcome. In summary, the sample space is a crucial component of any computer simulation. It defines the set of all possible outcomes that can occur and allows for the generation of reliable data and statistical analysis. By understanding the concept of sample space and how it is used in computer simulations, you can improve your ability to model complex systems and make informed decisions based on the data.

every computer connected to the internet uses the ____ suite to communicate between networks.
Every computer connected to the internet uses the Internet Protocol (IP) suite to communicate between networks. The IP suite is a set of communication protocols that governs how data is transmitted across the internet. It includes several protocols, such as Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Internet Control Message Protocol (ICMP), and Internet Group Management Protocol (IGMP).
TCP is the most commonly used protocol in the IP suite. It establishes a connection between two computers and ensures reliable transmission of data. UDP, on the other hand, is a simpler protocol that does not establish a connection before transmitting data. This makes it faster than TCP, but also less reliable. ICMP is used for error reporting and diagnostic purposes, while IGMP is used for multicasting. The IP suite is the foundation of the internet and enables communication between computers across different networks. It allows computers to send and receive data packets, which are small units of information that are transmitted over the internet. These packets are routed through various networks until they reach their destination. The IP suite ensures that the packets are transmitted in the correct order and reassembled into the original data at the destination. In conclusion, the IP suite is essential for communication between computers on the internet and enables the reliable transmission of data across networks.

True/False: It is possible for a structure to contain as a member a pointer to its own structure type.
True, it is possible for a structure to contain as a member a pointer to its own structure type. This is commonly used in linked lists and tree data structures where each element (node) contains a reference (pointer) to another element of the same structure type.
Using a pointer to its own structure type enables a data structure to be constructed as a series of interconnected nodes. Each node contains data and a pointer to the next node in the structure. By defining the pointer as a member of the structure, a new node can be dynamically allocated and connected to the previous node by updating the pointer. This allows for the creation of dynamic data structures that can grow or shrink in size during program execution. However, it is important to manage the pointers carefully to prevent issues such as segmentation faults and infinite loops.

In SQL (Structured Query Language), the command "DROP TABLE" is used to delete a table from a database. The syntax for the command is: sql
DROP TABLE table_name;
In this case, "smaller" is the name of the table that is being removed. It is important to note that once a table is dropped, all of the data and schema associated with that table is permanently deleted and cannot be recovered. Therefore, it is important to exercise caution when using the DROP TABLE command and to ensure that the table being dropped is the intended target.

ERP-OFDM stations can not connect with OFDM AP's because the use different __________. freq
ERP-OFDM stations cannot connect with OFDM APs because they use different frequency bands, which prevents them from being able to communicate with one another.
ERP-OFDM stations and OFDM AP's are two types of wireless communication devices that operate on different frequencies. The ERP-OFDM stations use frequencies in the range of 2.4 GHz to 2.4835 GHz, whereas the OFDM AP's operate in the frequency range of 5 GHz. This means that ERP-OFDM stations and OFDM AP's cannot connect with each other due to the difference in their operating frequencies.
In conclusion, the reason why ERP-OFDM stations cannot connect with OFDM AP's is because they use different frequencies. While ERP-OFDM stations operate in the 2.4 GHz to 2.4835 GHz frequency range, OFDM AP's operate in the 5 GHz frequency range. As a result, these two types of wireless communication devices are incompatible with each other.
