Answer:
Step 1:
OSI stands for Open Systems Interconnection.
OSI model was developed by the International Organization for Standardization(ISO). It is a reference model for how applications communicate over a network. The OSI model characterizes computing functions into a universal set of rules and requirements in order to support interoperability between different products and software.
The OSI model can be considered as a universal language for computer networking. It is based on the concept of divide and conquers, it splits up the communication system into 7 abstract layers, and the layer is stacked upon the previous layer.
Layers of OSI Model:
OSI model has seven layers which are as follows:
The Physical LayerThe Data Link LayerThe Network LayerThe Transport LayerThe Session LayerThe Presentation LayerThe Application LayerStep 2
Routers – A router is a device like a switch that routes data packets based on their IP addresses. Router is mainly a Network Layer device. Routers normally connect LANs and WANs together and have a dynamically updating routing table based on which they make decisions on routing the data packets. Router divide broadcast domains of hosts connected through it.
Gateway – A gateway, as the name suggests, is a passage to connect two networks together that may work upon different networking models. They basically work as the messenger agents that take data from one system, interpret it, and transfer it to another system. Gateways are also called protocol converters and can operate at any network layer. Gateways are generally more complex than switch or router.
Switch – A switch is a multiport bridge with a buffer and a design that can boost its efficiency(a large number of ports imply less traffic) and performance. A switch is a data link layer device. The switch can perform error checking before forwarding data, that makes it very efficient as it does not forward packets that have errors and forward good packets selectively to correct port only. In other words, switch divides collision domain of hosts, but broadcast domain remains same.
Which device will be used if you face an issue of weak signals during transmission.
Router device will be useful mostly for issue of weak signals during transmissin.
Mention on which level of OSI model these devices will work efficiently.
All these three devices router, gateway and switch work efficiently at hardware layers such as physical layer, datalink layer and network layer.
Step 3
Transmission impairment:
In the data communication system, analog and digital signals go through the transmission medium. Transmission media are not ideal. There are some imperfections in transmission mediums. So, the signals sent through the transmission medium are also not perfect. This imperfection cause signal impairment.
It means that signals that are transmitted at the beginning of the medium are not the same as the signals that are received at the end of the medium that is what is sent is not what is received. These impairments tend to deteriorate the quality of analog and digital signals.
There are three main causes of impairment are,
Attenuation
Distortion
Noise
1.Attenuation:
Here attenuation Means loss of energy that is the weaker signal. Whenever a signal transmitted through a medium it loses its energy, so that it can overcome by the resistance of the medium.
That is why a wire carrying electrical signals gets warm, if not hot, after a while. Some of the electrical energy is converted to heat in the signal.
Amplifiers are used to amplify the signals to compensate for this loss.
2.Distortion:
If a signal changes its form or shape, it is referred to as distortion. Signals made up of different frequencies are composite signals. Distortion occurs in these composite signals.
Each component of frequency has its propagation speed traveling through a medium and therefore, different components have different delay in arriving at the final destination.
It means that signals have different phases at the receiver than they did at the source.
3. Noise:
Noise is another problem. There are some random or unwanted signals mix up with the original signal is called noise. Noises can corrupt the signals in many ways along with the distortion introduced by the transmission media.
Noise may be divided into four categories:

-Refinement
-Modularity
-Abstraction
-Control hierarchy
is a process that elaborates on each design component until it reaches the coding details.
-Software procedure

-Software architecture
-Structural partitioning
-Modularity
-Data Structure
represents logical relationships between individual data elements.
Answer:
1. Modularity.
2. Refinement.
3. Structural partitioning.
4. Data Structure.
Explanation:
A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;
1. Planning.
2. Analysis.
3. Design.
4. Development (coding).
5. Deployment.
6. Maintenance.
One of the most important steps in the software development life cycle (SDLC) is design. It is the third step of SDLC and comes immediately after the analysis stage.
Basically, method design is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard. Some of the models or techniques used in the design of a software are;
Modularity: refers to the concept that software architecture has the ability to divide into modules and that eachmodule can be examined independently. Refinement: is a process that elaborates on each design component until it reaches the coding details.Structural partitioning: allows designers to split a program structure horizontally and vertically.Data Structure: represents logical relationships between individual data elements.Wiliam would like to sort a list of items after the data is already entered

What is the difference between the casual and consultative conversation? Why is it important for a person to know the difference between the two?
Answer:
The answer is below
Explanation:
Casual conversation is a form of conversation that occurs between friends and families. There are no specific rules or manner in which the participants speak to each other. It is otherwise known as Informal Conversation.
Consultative conversation on the other hand is a form of conversation that occurs between people who have a close relationship but not actual friends or families.
For example, people involved in this type of conversation are the likes of Doctors and Patients, Counsellors and Students, etc. It is often considered a Semi-formal conversation.
The reason a person needs to know the difference between the two styles of conversation is for individuals to know how to present and conduct themselves appropriately during the conversation.

Answer:
I would say D) Its an enviroment for running and testing the source code.
Explanation:
An integrated development environment (IDE) is a software suite that consolidates basic tools required to write and test software.
Developers use numerous tools throughout software code creation, building and testing. Development tools often include text editors, code libraries, compilers and test platforms. Without an IDE, a developer must select, deploy, integrate and manage all of these tools separately. An IDE brings many of those development-related tools together as a single framework, application or service. The integrated toolset is designed to simplify software development and can identify and minimize coding mistakes and typos.
Some IDEs are open source, while others are commercial offerings. An IDE can be a standalone application or it can be part of a larger package.
Answer:
D. It's an environment for running and testing the source code.
