Port unreachable and TTL (Time to Live) Expired messages are received at the sending host.
In cases when a packet reaches an end-host destined for a UDP port for which no host is associated, it generates an ICMP port unreachable in response. Also, an ICMP Port unreachable message can be generated in instances where the router could not find the server.
TTL expired on the other hand is used upon the execution of traceroute command. An ICMP message is sent out with a TTL value of 1 set in the IP header. The end host receiving a traceroute probe would send a TTL Expired ICMP when a single probe finally reaches it.
Final answer:
The "Time Exceeded" and "Destination Unreachable" messages are two types of ICMP messages received by a host running traceroute when a packet's TTL expires or the packet cannot be delivered.
Explanation:
The two types of ICMP messages received at the sending host executing the traceroute program are "Time Exceeded" messages and "Destination Unreachable" messages. The "Time Exceeded" message is received when a packet's time-to-live (TTL) value has reached zero before reaching its destination, prompting the intermediary router to send this message back to the source. The "Destination Unreachable" message is sent back if, for some reason, the packet could not be delivered to the destination host or if a communication port is not available.

Kenneth's manager has been receiving complaints that Kenneth is rude when he's conversing over email. Which email etiquette has Kenneth violated?
A He sent big files as attachments.
B He hasn't specified the intent of the email in the subject field.
C He hasn't been direct while writing his email.
D He didn't check for grammatical and spelling errors.
E He didn't use the proper tone in the emails he writes.
The correct answer is E. He didn't use the proper tone in the emails he writes.
Explanation:
Etiquette in email communication and similar contexts includes a set of rules that guarantee communication is effective and polite. In the case of proper tone, this refers to the attitude the person writing the message conveys, this can be polite, unpolite, honest, rude, etc. Additionally, the tone depends on the words used as well as other elements, for example not including a salutation might be interpreted as rude for many people.
According to this, Kenneth has probably violated the rule of using a proper tone because people complaints he seems rude in his email messages. This means, he probably did not use the appropriate words or elements and convey a negative attitude or tone.

What do you feel are the limitations of a computer that has no operating system? how would a user load and execute a program?
A computer without an operating system has significant limitations in user interaction and program execution, requiring manual and intricate knowledge of hardware for any operation.
Explanation:A computer without an operating system (OS) faces significant limitations. The OS acts as a mediator between the user and the computer's hardware, managing software resources and simplifying application programming. Without an operating system, a user would have to manually control the hardware, which is exceptionally complex and impractical for general users.
Without an OS, loading and executing a program would involve writing code directly to the hardware, typically using machine language or assembly language. This process is both error-prone and time-consuming, only feasible for advanced users with a deep understanding of computer architecture. For the average user, a computer without an OS would be nearly unusable for regular tasks.

“When using a public computer for browsing the Internet, try to use for________ transactions. Also, use__________ browsing whenever you can.”
FILL IN THE BLANK
Final answer:
Use non-sensitive transactions on public computers and engage in private browsing. Disconnect from the internet before opening downloaded documents. For security, use a personal device with Chrome.
Explanation:
When using a public computer for browsing the Internet, try to use non-sensitive transactions. Also, use private or incognito browsing whenever you can. It's important to be cautious about entering identifying information into a website, such as your address, and be wary of downloading documents that could access the internet, like photos, Word documents, or PDFs. If necessary, disconnect from the internet before opening such a document. Remember that the most basic version of encrypted communications is in-transit encryption, which protects the content of your communications when browsing the web. For essential online activities, it is recommended that users complete these using a desktop or laptop computer and in Chrome for better security and performance.
what is NOT powered by the PSU of your computer?
The PSU does not directly power peripheral devices like the keyboard or mouse, which are powered via USB ports.
The PSU (Power Supply Unit) of a computer is responsible for powering most of the internal components. This includes the motherboard, CPU (Central Processing Unit), RAM (Random Access Memory), GPU (Graphics Processing Unit), hard drives, and SSDs (Solid-State Drives). However, one component that is not powered directly by the PSU is the peripheral devices, such as a keyboard or mouse. These devices instead receive power through the computer's USB ports.
Components Not Powered by the PSU
Keyboard MouseThese examples illustrate how the PSU functions primarily to power core internals of the computer, leaving the task of powering peripherals to other means.

If a submarine's viewing port has a surface area of 0.0100 m2, the force exerted by the water on it at this depth will be 416,000 N in magnitude.
What is submarine's viewing port?If a submarine's viewing port has a surface area of 0.0100 m2, the force exerted by the water on it at this depth will be 416,000 N in magnitude. The two fluid pressures that are in play are the internal atmospheric air pressure and the external water pressure, which includes the atmosphere operating on it at the surface.
The net force due to fluid pressure can be calculated by using the gauge pressure of the water since the atmospheric pressure acts both internally and is also included in the water pressure and the air pressures virtually cancel each other out.
A force is a vector quantity since it has b0th magnitude and direction. It is calculated using newtons as the SI unit of mea.sure (N). F stands for force (formerly P).
Therefore, If a submarine's viewing port has a surface area of 0.0100 m2, the force exerted by the water on it at this depth will be 416,000 N in magnitude.

What is the name of the redesign heuristic that suggests checking the completeness and correctness of incoming materials?
The heuristic is called the **"Ingestion Heuristic,"** focusing on verifying completeness and correctness of incoming materials before processing.
The heuristic you're referring to is known as the **"Ingestion Heuristic."** This concept is particularly relevant in redesigning systems or processes where materials, data, or information are received or ingested from external sources.
The main focus of the ingestion heuristic is to ensure that the incoming materials are complete and correct before they are processed further or utilized within the system.
In practical terms, applying the ingestion heuristic involves establishing clear criteria or checks to verify the completeness and correctness of incoming materials. This may include checking for missing data, validating the format or structure, ensuring data integrity, and verifying the accuracy of content.
By implementing robust ingestion processes guided by this heuristic, organizations can minimize errors, reduce processing delays, and enhance overall reliability and quality of operations.
Overall, the ingestion heuristic underscores the importance of proactive validation and quality assurance at the point of material intake, thereby promoting efficiency and reliability throughout the system's workflow.
