Answer:
a. Telnet transmissions are not encrypted.
Explanation:
Indeed, since <em>Telnet transmissions are not encrypted,</em> all the information sent, and even the characters typed in the telnet console are sent in clear text.
This is a security issue, since any other device in the same network will receive a copy of the information (packets) sent. For default, all the devices, except for the server expecting to receive the information, will discard the packets. However it is easy to actively <em>listen </em>and keep those packets, wich will contain the information in plain text and human readable.
Answer:
D
Explanation:
Two dimensional array contain both rows and columns. Each row represented one record and each column represent one filed in that record.
for ex: int grades[5][3];
here array grades contains 5 rows and in each row we have 3 columns
if we have grades[i][j] then " i " represents number of rows and j represents the number of columns in that row.
j<grades[i].length represents i=0 to 2[here no of columns are 3, array index starts from 0 to 2]
The Answer is D
Answer:
C. Inaccurate and misleading data can be more easily disseminated to scientific researchers.
Explanation:
The above one is certainly the correct option. We know these kinds of the database as an open database, and these are available for all on the internet. The best example is the World Bank database, Census.org is also a good example. All these databases are a huge collection of data sets with meaningful data. The inaccurate and misleading data is never thought to be spread among the scientific researchers easily as it is not good for research, and requires a huge level of data cleaning. Hence, C. is the correct option here as it is not an advantage.
prism is (geometry) a polyhedron with parallel ends of the same size and shape, the other faces being parallelogram-shaped sides while cone is (label) a surface of revolution formed by rotating a segment of a line around another line that intersects the first line.
