(D) HTTP, or hyper-text transfer protocol, is the standard or set of rules that governs how web pages are sent over the internet.
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.
Answer:
1. The Sun is the primary source of energy that influences any planet's temperature, including Earth. The amount of energy received from the Sun is called insolation; the ratio reflected is called the albedo.
2.There are three major ways in which global warming will make changes to regional climate: melting or forming ice, changing the hydrological cycle (of evaporation and precipitation) and changing currents in the oceans and air flows in the atmosphere
3.The warming of Earth is primarily due to accumulation of heat-trapping greenhouse gases, and more than 90 percent of this trapped heat is absorbed by the oceans. As this heat is absorbed, ocean temperatures rise and water expands. This thermal expansion contributes to an increase in global sea level.
4.The main sources of greenhouse gases due to human activity are: burning fossil fuels leading to higher carbon dioxide concentrations. farming and forestry — including land use change via agriculture and livestock. cement manufacture.
5. - Reduce, Reuse, Recycle
- Use Less Heat and Air Conditioning
-Use Less Hot Water
Explanation:
Answer: True
Explanation: In data mining, they use statistics component for the analyzing of the large amount of data and helps to deal with it. Statistics provide the techniques for the analyzing, evaluating and dealing with the data that is known as data mining.Data statistics provide the help to organize large data in a proper form and then analyze it. Thus, the statement given is true that data mining must use statistics to analyse data.
Answer:
see explaination
Explanation:
function [] =
inverse(A,B)
da = det(A);
disp("The det of A is");
disp(da);
inva = inv(A);
disp("The inverse of A is");
disp(inva);
x = inva*B;
disp("The value of X is");
disp(x);
rk = rank(A);
disp("The rank of X is");
disp(rk);
Di = eig(A);
disp("The eigen values of A is");
disp(Di);
[V,Di] = eig(A);
disp("The eigen vectors of A are (Each column represents one column vector)");
disp(V);
end
A = [1,2;4,5];
B = [1,2;4,5];
inverse(A,B);
%ab = [num2str(t)," ",num2str(dx)," ",num2str(dy)];
%disp(ab);
