Answer:
Ok, so it's not letting me submit a text response, so I'll attach an image of my answer.
Explanation:
The answer is B. A only. The optimum valve timing is found through experimentation using an engine dynamometer. The timing of the opening and closing of the valves is called valve timing. So the use of dynamometer measures the power output of a machine that is why it can measure the optimum valve timing.
Answer:
Implement better protection and inform the staff.
Explanation:
The situation given in the question can be very alarming for a healthcare organization since the laptops contain critical information and details about the employee's work.
To prevent this from occuring again in the future, the organization should educate their employees on cyber security and having a strong password. They also should implement softwares on the computers against such incidents, which can be softwares that can lock the computers and delete files that are important to the organization if an unauthorized entry is detected. In order to protect the information, they can also use a backup system for every computer the employee's use.
I hope this answer helps.
Answer:
I. Algorithms can be written using pseudocode.
II. Algorithms can be visualized using flowcharts.
Explanation:
An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.
The two statements which are true about algorithms are;
I. Algorithms can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.
II. Algorithms can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
Basically, a flowchart make use of standard symbols such as arrows, rectangle, diamond and an oval to graphically represent the steps associated with a system, process or workflow sequentially i.e from the beginning (start) to the end (finish).
Answer:
Stateful protocol analysis detection.
Explanation:
IDS and IPS are acronym for intrusion detection system and intrusion prevention system respectively. IDS is a security system which monitors the network traffic and notifies the engineer when there's a malicious activity. IPS is a security system which monitors the network traffic and blocks malicious activity as well as keeping logs.
Generally, the detection methods used by the Intrusion Prevention Systems (IPS) are;
1. Statistical anomaly-based detection.
2. Signature-based detection.
3. Stateful protocol analysis detection.
Stateful protocol analysis detection is an IDS/IPS detection method that uses previously gained connection attributes to match traffic against predetermined profiles.
Basically, these predetermined profiles comprises of benign activities and suspicious activities that have been developed by industry leaders and vendors as abnormal systems or network behaviors.
