how does the session ID differ from port number?
A session ID is a unique number that a Web site's server assigns a specific user for the duration of that user's visit (session). The session ID can be stored as a cookie, form field, or URL (Uniform Resource Locator). Some Web servers generate session IDs by simply incrementing static numbers. However, most servers use algorithms that involve more complex methods, such as factoring in the date and time of the visit along with other variables defined by the server administrator.
while,A port number is a way to identify a specific process to which an Internet or other network message is to be forwarded when it arrives at a server. For the Transmission Control Protocol and the User Datagram Protocol, a port number is a 16-bit integer that is put in the header appended to a message unit. This port number is passed logically between client and server transport layers and physically between the transport layer and the Internet Protocol layer and forwarded on.
For example, a request from a client (perhaps on behalf of you at your PC) to a server on the Internet may request a file be served from that host's File Transfer Protocol (FTP) server or process. In order to pass your request to the FTP process in the remote server, the Transmission Control Protocol (TCP) software layer in your computer identifies the port number of 21 (which by convention is associated with an FTP request) in the 16-bit port number integer that is appended to your request. At the server, the TCP layer will read the port number of 21 and forward your request to the FTP program at the server.
Some services or processes have conventionally assigned permanent port numbers. These are known as well-known port numbers. In other cases, a port number is assigned temporarily (for the duration of the request and its completion) from a range of assigned port numbers. This is called an ephemeral port number.

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.

Which describes the conditions that must be met in order to use Subtotal in a spreadsheet? The data must be in adjacent cells and organized in rows using headings. The data must be in adjacent cells and organized in columns using headings. The data must be distributed in different spreadsheets using the same range of cells. The data must be distributed in different tabs within the same spreadsheet using the same range of cells.
You can always add subtotals that contain the same function to several columns at the same time. In most cases, subtotals evaluate values based on categories in another column. For instance, when the value in column A changes, the corresponding value in column B is evaluated.

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.

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.

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.
