Answer:

Data link layer of OSI model is creating the erroneous segments

Explanation:

The Open System Interconnection (OSI) model is a conceptual framework about how communication occurs between devices over the Internet. It has seven layers, (Physical, Data, Network, Transport, Session, Presentation and Application layer). The purpose of this hierarchical layer system is to understand the structure of communication between devices and do troubleshooting easily if a fault occurs. As in this question, Marry is troubleshooting her company LAN network. She finds out that data segments that the client is encoding are resulting in errors in the encoding. Now the question arises, how she found the cause of the error. The OSI model helps her in understanding the problem.

As you know, the data link layer of the OSI model is responsible for the encoding and decoding of data segments. This layer ensures the reliability of the physical layer, and responsible to provide error-free transfer of data from one node to another on a network. It is also responsible for frame synchronization and flow control. The data link layer is divided into sub-layers:

1. Media Access Control Layer: this layer controls how a computer on the network gains access to the data and transmission permission.

2. Logical Link Control Layer: This layer controls frame synchronization, error checking and flow control.

Therefore, Marry founds data link layer of the OSI model is creating the erroneous segments in encoding.

In a folder hierarchy, the top level is referred to as which of the following?
Vesnalui [34]

Answer:

B. root

Explanation:

Every user in Linux is assigned a folder from which they can store their files. The interpreter allows you to abbreviate your route with the “~” symbol. The ls command without any additional data shows the files in the current directory, but if after the name of the command a path is written, it shows the files in that path. Therefore, the ls ~ command shows the files in the user's folder.

In addition to the folders and files created by the user or programs, every Linux folder has two subfolders defined by default:

“..”: It is the top level folder in the file hierarchy that contains it. This subfolder is also present in the root of the filesystem (the folder with absolute path “/”), but points to itself.

“.”: It is the folder itself that appears as if it were also a subfolder. It can be considered as a "self-reference" or pointer to itself.

These folders are normal folders in the system for all purposes; that is, they can be used on routes. For example, the path /dirA/dirB/dirC/../fichero2.txt refers to the file that is stored in the dirB folder, since from dirC, the folder .. points to its predecessor, dirB. The following figure shows the interpretation of this route as well as the equivalent of the “..” and “.” Folders.

2. What is data, information, knowledge and data Science? Define the role of data in emerging technology? ​
xz_007 [3.2K]
Answer :
Before answering the question. We look to it in your real life. The minute you wake up and open your eyes, your eyes collect all the information of the room you are in and your brain segregates them depending on the need. So that once you recall that memory it will be already saved in your brain. So your brain is like a computer.
You are collecting data ( information ) of what ever you hear , look and even imagine all day. For extra knowledge, when you put that memory into a form of ( writings , or art if you were an Arabist ) it’s called data visualization.
You are now the data scientist, you collected information form all the surroundings and it’s up to you to display it the way you want but that data must be correct
——
To the real short cut answer

Data , The data is information that is being stored by a computer. This data may be in the sort of text, images, audio clips, software applications, or other varieties of data


Information , information is a term used to describe text that is informative to the individual reading it or the computer processing it.

Or

Information is defined as knowledge gained through study, communication, research, or instruction. Essentially, information is the result of analyzing and interpreting pieces of data. Whereas data is the individual figures, numbers, or graphs, information is the perception of those pieces of knowledge.

Knowledge, In information technology, knowledge is, to an enterprise or an individual, the possession of information or the ability to quickly locate it.


Data science, Data science is the field of applying advanced analytics techniques and scientific principles to extract valuable information from data for business decision-making, strategic planning and other uses.

Your final answer is : Data has the potential to drive better outcomes, processes and of course, new technology that could be the next major industry disruption and breakthrough.”
