Answer:

Following are the responses to the given question:  

Explanation:

This list is based mostly on the processor. Then you'll be ordered. An interrupt of a particular cable (wire) is produced for PC-ish CPUs (IRQ 0 - 31 for some intel processors). The bigger challenge is a lower number.

Strange factors have included a system clock, power business, 0, some reserved for use by CPU testing, serial/parallel/... ports and also some terminated/error/state/new devices requests device Thus a key touch on the keyboards could create an interrupt that was direct on old devices.

Answers

Answer: Data Transmission mode defines the direction of the flow of information between two communication devices.

Explanation:

It is also called Data Communication or Directional Mode. It specifies the direction of the flow of information from one place to another in a computer network.

A channel or path through which the data or information is transferred form one place to another in a computer network is called communication channel.

What is communication channel?

Information is transported from one network device to another over a communication channel.

Data is transported across wired channels using cables and wires. Without using cables or wires, wireless channels transmit data from one device to another.

Data communication is the process of transferring data from one device to another via a transmission medium of some kind.

The system bus is a network of wires and connectors that carries data between a computer's primary memory and its processors.

For data and control signals travelling between the main parts of the computer system, the bus offers a communication path.

Thus, communication channel is the path for data transfer.

Question:

The remove() method in the Queue interface ________.

A. retrieves, but does not remove, the head of this queue, returning null if this queue is empty

B. retrieves and removes the head of this queue, or null if this queue is empty

 

C. retrieves, but does not remove, the head of this queue, throwing an exception if this queue is empty

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

Answer:

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

Explanation:

In Java, the Queue interface is found in the java.util package and inherits from the Collection interface. It is used to store elements which are processed in the order in which they are inserted. This means that the first element will be processed first.

The Queue interface has many methods. Some of them are;

i. add(): allows elements to be added to the queue.

ii. remove(): retrieves and removes elements from the head of the queue. The head of the queue points to the first element of the queue. If the queue is empty, the remove() method throws an exception called the NoSuchElementException

iii. poll(): retrieves and removes the element at the head of the queue. Unlike the remove() method, if the queue is empty, a null is returned.

iv. peek(): retrieves but does not remove the element at the head of the queue. Just like the poll() method, a null is returned if the queue is empty.

Answers

Answer:

NIST SP 800 30

Explanation:

Cyber security can be defined as a preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

Risk management can be defined as the process of identifying, evaluating, analyzing and controlling potential threats or risks present in a business as an obstacle to its capital, revenues and profits.

This ultimately implies that, risk management involves prioritizing course of action or potential threats in order to mitigate the risk that are likely to arise from such business decisions.

NIST is acronym for National Institute of Standards and Technology and it's under the U.S. Department of Commerce. The NIST cybersecurity framework (CSF) is a powerful tool that provide guidelines for both the external and internal stakeholders of organization on how they can effectively and efficiently organize, manage, and improve their cybersecurity programs, so as to mitigate the risks associated with cybersecurity.

The NIST SP 800 30 is a risk mitigation framework that provide guidance for conducting or allows scope for research, assessment and acknowledgement for risk mitigation of federal information systems and organizations.

Typically, NIST SP 800 30 is used for translating cyber risk so that it can easily be understood by the chief executive officer (CEO) and board of both a public and private organization.
