Answer:
following are the OSI Layers
1.physical layer
2.datalink layer
3.network layer
4.transport layer
5.session layer
6.presentation layer
7.application layer
Explanation:
physical layer is used to transmit media,signal and binary information
datalink layer is used for physical addressing MAC and LLC
network layer is used for path determination and ip
transport layer is for end to end communication and reliability
session layer is for interhost communication
presentation layer is for data representation and encryption
application layer is network process to application

Answer: (B) Lossless compression
Explanation:
According to the question, the given technique is the example of the lossless compression. The lossless compression is one of the technique that decompress the data into the original data form without any type of losses.
The lossless compression is the technique that usually compress the data, text and the databases. This technique also improve the compression rate helps in reconstruct the original data. It is used in various types of encoding methods, GNU tool and zip file.
Here is a somewhat cryptic solution that works:
#include <algorithm>
#include <cstdlib>
using namespace std;
void q(char c, int count)
{
for (int i = 0; i < count; i++) {
putchar(c);
}
}
void p(int b1, int plusses)
{
q(' ', b1);
q('+', plusses);
}
int main()
{
for (int i = -3; i <= 3; i++)
{
int pl = min(6, (3 - abs(i)) * 2 + 1);
p(6-pl, pl);
i == 0 ? p(0, 6) : p(6, 0);
p(0, pl);
putchar('\n');
}
getchar();
}
