Circuit switching is a widely used method for connecting nodes on a network. It involves establishing a dedicated communication path between two nodes for the duration of a connection, ensuring a consistent and uninterrupted transmission.

Circuit switching works by reserving network resources, such as bandwidth, for the entire duration of a communication session. When a connection is established, a dedicated path is established between the sender and receiver, enabling the direct exchange of data packets. This method guarantees a fixed transmission capacity and low latency, making it suitable for real-time applications like voice and video calls. However, circuit switching requires significant resources even when the connection is idle, making it less efficient for sporadic or bursty traffic. Nevertheless, its reliability and consistent performance have made it popular for traditional telephone networks and certain dedicated communication systems.

An application-level protocol implementing streaming video in the internet would most likely use the Transmission Control Protocol (TCP) as its transport-layer protocol.

When it comes to streaming video over the internet, TCP is the preferred choice for the transport-layer protocol. TCP offers reliable and ordered delivery of data, which is crucial for streaming applications that require the continuous and uninterrupted transmission of video content.

Streaming video involves sending a continuous stream of data packets from a server to a client. TCP provides features such as error correction, congestion control, and flow control, ensuring that the video data is transmitted reliably and efficiently across the network. It guarantees that packets are delivered in the correct order, retransmitting any lost or corrupted packets to maintain the integrity of the video stream.

UDP (User Datagram Protocol) is another transport-layer protocol commonly used for streaming applications. However, UDP does not offer the same level of reliability as TCP. It is connectionless and does not perform error correction or retransmission, which can result in packet loss or out-of-order delivery. While UDP is often chosen for real-time streaming or low-latency applications, TCP is more suitable for high-quality, uninterrupted streaming video where data integrity is paramount.

Therefore, an application-level protocol implementing streaming video in the internet would most likely rely on TCP as its transport-layer protocol.

Attempting to use a local variable outside the function in which it is declared typically results in an error. Local variables are only accessible within the scope of the function in which they are declared.

In most programming languages, local variables have a limited scope and lifetime within the function in which they are declared. They are typically allocated on the stack and exist only while the function is executing. Once the function finishes executing, the local variables are destroyed, and their memory is deallocated.

Attempting to use a local variable outside its scope, such as in another function or outside any function, will likely result in a compilation error or runtime error. The variable is not accessible or recognized outside its declared function's scope, and referencing it would lead to undefined behavior.

To access a variable outside its function's scope, it needs to be declared as a global variable or passed as a parameter to other functions. Global variables have a wider scope and can be accessed from any part of the program, but they may introduce issues like name clashes or reduced code maintainability.

The statement is true. The strongest predictors of multitasking are observing others engaging in electronic multitasking and beliefs about what others in the workplace would think about someone who multitasks.

Research in the field of psychology and workplace behavior has found that the observation of others engaging in electronic multitasking and beliefs about social perceptions play significant roles in predicting individual multitasking behavior. People tend to mimic the behaviors they observe in others, and if they see their colleagues or peers multitasking with electronic devices, they are more likely to engage in similar behavior. Furthermore, individuals' beliefs about what others in the workplace would think about someone who multitasks also influence their own multitasking behavior. Social norms and expectations can shape individuals' choices and actions. If someone believes that multitasking is perceived positively in their workplace or that it is expected of them to multitask, they are more likely to engage in multitasking behaviors.

These two factors, observation of others engaging in electronic multitasking and beliefs about social perceptions, can be strong predictors of an individual's inclination to multitask. By understanding these influences, organizations can develop strategies to promote focused work, minimize distractions, and establish clear communication about multitasking norms in the workplace.

The portion of the operating system that selects the next process to run is called the scheduler. The scheduler is a vital component of an operating system that is responsible for determining which process or thread should be executed next on the CPU.

Its primary role is to allocate the available system resources efficiently and fairly among the running processes. The scheduler plays a crucial role in multitasking environments where multiple processes are competing for CPU time. There are different types of schedulers, including long-term scheduler (also known as admission scheduler), short-term scheduler (also known as CPU scheduler), and medium-term scheduler. The long-term scheduler selects processes from the job queue and brings them into the main memory for execution. The short-term scheduler selects the process from the ready queue to run on the CPU, based on priority, time quantum, or other scheduling algorithms. The medium-term scheduler manages processes that are in a suspended state and decides whether to keep them in memory or swap them out to secondary storage.

The scheduler's main objective is to optimize resource utilization, enhance system performance, and ensure fairness in process execution. Different scheduling algorithms, such as First-Come, First-Served (FCFS), Round Robin (RR), Shortest Job Next (SJN), and Priority Scheduling, are employed by the scheduler to determine the order of process execution.
