Explanation:

Email was the wrong message medium for Patterson in this case because the content of his message was sensitive and emotionally charged. The email was critical of his colleagues and management, and it contained personal frustrations.

Email is a relatively impersonal and asynchronous communication channel, which makes it unsuitable for handling delicate matters that require immediate attention and understanding.

In this situation, a better fit for Patterson would have been a face-to-face conversation or a virtual meeting. These mediums allow for real-time communication, providing an opportunity for immediate clarification, empathy, and understanding. Additionally, face-to-face interactions can help establish a more personal connection, fostering better relationships and reducing the likelihood of misinterpretation or defensiveness.

If Patterson had still decided to use email, he should have opted for a more formal and diplomatic tone. The email formality schematic suggests that in professional settings, a more formal approach is appropriate, especially when discussing sensitive issues or expressing criticism. A neutral and polite tone would have helped to maintain professionalism and prevent any unintended negative consequences that arose from the use of informal language and strong emotions in the original email

Answer:

4. Command line interface (CLI)

Explanation:

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

A Command line interface (CLI) refers to a text-based user interface that allow users to operate a software application or program, as well as manage and execute operating system functions by typing standard line of commands into the text-based user interface with a real-time response.

Basically, the CLI is solely text-based and as such requires a thorough knowledge and understanding of global commands, as well as administrative privileges in some cases.

Hence, the operating system function which has a steeper learning curve (more difficult to learn) and can potentially break the system without careful use of its operations is the Command line interface (CLI).

The packet transmission delay at the sender is 0.01 seconds or 10 milliseconds. The packet transmission delay at the sender can be calculated by dividing the size of the packet by the transmission rate of the link.  

To calculate the packet transmission delay at the sender, we divide the packet size by the transmission rate of the link.

Packet Transmission Delay = Packet Size / Transmission Rate

In this case, the packet size is 1 Mbit (105 bits) and the transmission rate is 100 Mbps (100 x 106 bits per second).

Packet Transmission Delay = 105 bits / (100 x 106 bits per second)

= 1 / (100 x 10^-2) seconds

= 1 / 100 seconds

= 0.01 seconds

File transfer protocol (FTP)

Explanation:

An information can be defined as an organized data which typically sent from a sender to a receiver. When a data is decoded or processed by its recipient it is known as information.

Generally, there are several channels or medium through which an information can be transmitted from the sender to a receiver and vice-versa. One of the widely used media is the internet, a global system of interconnected computer networks.

There's a standard framework for the transmission of informations on the internet, it is known as the internet protocol suite or Transmission Control Protocol and Internet Protocol (TCP/IP) model. One of the very basic rule of the TCP/IP protocol for the transmission of information is that, informations are subdivided or broken down at the transport later, into small chunks called packets rather than as a whole.

The three (3) main types of TCP/IP protocol are;

I. HTTP.

II. HTTPS.

III. FTP.

File transfer protocol (FTP) is used between two or more computers. One computer sends data to or receives data from another computer directly through the use of network port 20 and 21.

To solve the topological sorting problem using a DFS-based approach in C/C++, we can start by representing the directed acyclic graph (DAG) using an adjacency list. Then, we can perform a DFS traversal of the graph starting from any vertex, and use a stack to store the vertices in the order they are visited. Once the DFS traversal is complete, the vertices in the stack can be popped one by one to obtain a valid topological ordering of the graph.

Here's some sample code that implements this approach:

```
#include
using namespace std;

void dfs(vector adj[], int v, bool visited[], stack &s)

{
   visited[v] = true;
   for(int i=0; i adj[], int n)

   {
   bool visited[n];
   memset(visited, false, sizeof(visited));
   stack s;
   for(int i=0; i> n >> m;
   vector adj[n];
   for(int i=0; i> u >> v;
       adj[u].push_back(v);
   }
   topologicalSortDFS(adj, n);
   return 0;
}
```

To solve the topological sorting problem using a source-removal approach in C/C++, we can start by representing the DAG using an adjacency matrix. Then, we can repeatedly remove vertices with no incoming edges (i.e., vertices with all their incoming edges already removed) and add them to the topological ordering of the graph. This process is repeated until all vertices have been removed, or until it is determined that the graph contains cycles.

Here's some sample code that implements this approach:

```
#include
using namespace std;

void topologicalSort(vector> adj, int n) {
   vector inDegree(n, 0);
   for(int i=0; i q;
   for(int i=0; i order;
   while(!q.empty()) {
       int u = q.front();
       q.pop();
       order.push_back(u);
       for(int v=0; v> n >> m;
   vector> adj(n, vector(n, 0));
   for(int i=0; i> u >> v;
       adj[u][v] = 1;
   }
   topologicalSort(adj, n);
   return 0;

Answer:

Variable.

Explanation:

In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.

Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.

For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters

Hence, a variable is a changeable value recorded in Scratch's memory. Variables can only hold one value at a time, unlike lists.

In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.

Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.

Explanation:

A file can be defined as a computer resource that avails end users the ability to store or record data as a single unit on a computer storage device.

Generally, all files are identified by a name, icon, size, and type (format) such as audio, image, video, document, system, text, etc.

Furthermore, files are organized or arranged in directories. These directories are paths that describes the location wherein a file is stored on a computer system.

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem. Thus, it's a computer program or application that comprises of sets of code for performing specific tasks on the system.

In Computer science, it's possible to create a shortcut in several directories (locations) on a computer, so as to reference a file, folder or software application and serve as an executable link.

Hence, a shortcut is an icon that does not directly represent a file, folder or application but serves as a link to it.

Additionally, deleting the shortcut of a data file, folder or software application would not permanently delete or uninstall the main data file respectively.

A spectroscope is an instrument used to measure the properties of light, including its wavelength and intensity.

A spectroscope is an instrument used to measure the properties of light, including its wavelength and intensity. When used to observe the light emitted by a ceiling light, a spectroscope would reveal a range of colors or wavelengths, depending on the type of light bulb used.
For example, if the ceiling light used an incandescent bulb, the spectroscope would reveal a continuous spectrum of colors, ranging from red to violet. This is because incandescent bulbs emit light by heating a filament until it glows, creating a range of colors that blend together.
On the other hand, if the ceiling light used a fluorescent bulb, the spectroscope would reveal discrete lines of color, rather than a continuous spectrum. This is because fluorescent bulbs work by exciting gas molecules to emit light at specific wavelengths, creating distinct lines of color.
In general, a spectroscope can reveal a lot about the properties of light emitted by a ceiling light, including its color, brightness, and intensity. This information can be useful for understanding the characteristics of different types of lighting, as well as for diagnosing problems with light bulbs or fixtures.
