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.
When powering up the computer, the initial program loading and start-up is performed by using a ______________ program that is built permanently into a read-only part of memory for the computer?
Answer:
The answer is Bootsrap
Explanation:
A bootstrap program which is also referred to as a bootstrap loader is a program that resides in the computer’s Read Only Memory. It starts the whole chain reaction and ends up with the entire OS being loaded. This program reads the computer’s hard drive boot sector and continues with the process of loading the Operating System. It first performs a POST test and then proceeds to load the OS intothe main memory.
Write a recursive function, replace, that accepts a parameter containing a string value and returns another string value, the same as the original string except with each blank replaced by an asterisk "*".
The function taken in an argument which is a string and gives an output of the same string with a asterisk (*) inserted inbetween each word. The program written in python 3 goes thus :
def replace(sentence):
#initialize a function named replace which takes in a single string sentence
sent = sentence.split()
#the sentence is split based on whitespace as a list of words which is attached to the variable called sent.
return '*'.join(sent)
Inbetween two words, a asterisk is appended using the join method.
print(replace('i am here'))
#A sample run of the function with an example is given and the output attached below.

6) The 'info header' in Blender changes as different actions are carried out, serving as a 'roadmap'.7) It is false that you cannot use the manipulator widget to translate, rotate, or scale an object; the widget is designed for these actions.
6) In Blender's default 3-D view, the part that changes depending on what actions are being carried out on the screen, and acts as the 'roadmap', is the info header. The info header provides context-sensitive options and information related to the current tools and selections in use. When performing different actions like translate, rotate, and scale, the info header updates to reflect these actions and available options.
7) The statement that you cannot use the manipulator widget to translate, define, rotate, or scale an object in Blender is false. The manipulator widget, also referred to as the transform widget, is specifically designed to help users do exactly these things, with intuitive controls for translating, rotating, and scaling objects in the 3D space.

Instead of starting with a blank PowerPoint presentation, you can use a __________. slide spreadsheet template transition
Instead of starting with a blank PowerPoint presentation, you can use a template. The correct option is c.
What is PowerPoint?Scientists set out to develop a presentation tool that would make it simple to create and deliver slides. They called it Presenter, but PowerPoint eventually replaced it.
Using a template or from scratch, create presentations. Include text, pictures, artwork, and videos. Using PowerPoint Designer, pick a polished layout. Cinematic motion, transitions, and animation should be added.
If a slide is selected, it should appear right after the one that is currently selected. At the conclusion of the presentation, if you don't immediately see it, look again. You can drag and drop it to the location you desire, just like with any other slide.
Therefore, the correct option is c, template.

When you ____ software, you are adapting it from one type of computer or operating system to run on a different computer or operating system?
Answer: Port
Explanation :
When we port a software from one computer to another computer or from one operating system to another operating system, it tries to adapt to the new environment of the machine by checking the required the configurations of the machine and then checking the available files in the software to run the machine.
The porting of a software also checks whether the software is compatible with the machine or not and if not then why.

You have a subnetwork, 192.168.48.0/24. it is divided into subnet a and subnet
b. your boss wants to add a third subnet, c, with 16 hosts. is this possible? if yes, provide the network address of the new subnet you will be adding (i.e. 192.168.2.14). if it is not possible, select 'no' as your answer.
Final answer:
It is possible to add a third subnet that supports at least 16 hosts to the existing network. This would typically require a subnet mask of /28. The exact network address of the new subnet depends on the addresses occupied by subnets A and B.
Explanation:
Yes, it is possible to add a third subnet, C, with 16 hosts to the existing network of 192.168.48.0/24 which is divided into subnet A and subnet B. To accommodate a third subnet that supports at least 16 hosts, you would need to allocate enough IP addresses while considering the subnet mask that allows for 16 usable addresses. For 16 hosts, you would need a subnet mask of /28 (which provides 16 addresses, 14 of which are usable for hosts as one is the network address and another is the broadcast address).
Assuming subnets A and B are already optimized and taking the first available spaces, the third subnet, C, could start immediately after the space used by subnet B. Without specific details about subnets A and B’s size, calculating the exact starting address of C is not possible, but the pattern would be akin to 192.168.48.x/28, where 'x' is the next available byte following subnet B.

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.
