Answer:
Verbatim Identifier
Explanation:
- Verbatim Identifier contains @ symbol as a prefix by which enables you to use reserved words of a programming language as identifier. For example the keywords like int, double, goto, char, else, while, for, float etc can be used as strings or variable names if @ symbol is added before these words e.g. @char, @while, @void, @int etc.
- The compiler of a language will recognize such identifiers as verbatim identifiers and compiles them without giving an error that these are reserved words.
- Verbatim identifier is used for program that is written in other languages and those languages don't have same reserved words.
- For example: cout<<"use of verbatim identifier";<<@for; In this statement, for keyword which is used in for loop can be used as an identifier with @ in the prefix.
- The escape sequences if used with @ symbol in prefix then they are interpreted in a different way. For example in C#
string a = "\\C:\torrent\new\file";
Console.WriteLine(a);
This statement will give the following output:
\C: orrent
ewfile
This means that the \t in the start of torrent and \n in the start of new word is taken as an escape sequence and output displayed is giving tab space because of \t and prints the rest of the words in new line because of \n escape sequence.
Now lets use this with the @ symbol
string a = @"\\C:\torrent\new\file";
Console.WriteLine(a);
The output will now be:
\\C:\torrent\new\file
\t and \n are not taken as escape sequences by the compiler because of @ symbol.
Answer:
a. The information is first sent via a Broadband for efficient transmission, and if not successful, only then it is resent via a Baseband that exists as a backup network as packets b. The message is first broken down into small packets before being sent, then they are

Answer:
Topology means arrangement of nodes
Explanation:
In computer science the word topology means the arrangement of nodes and elements in a network. For any topology we do need nodes and cables for maintaining the infrastructure.
In mesh topology the all nodes use to get connected by direct link. While each and every node is directly associated with one another. In this infrastructure we do need lot cabling where every node will be connected with one another. While usage of good quality cable in network is also expensive to manage. Although there are lot of benefits of this topology, where the transmission of data would never stop if node is not working the rest will be working to transfer the data among other nodes ,this is more secure because there is no traffic for data to travel via many nodes to reach the destination. Every node is directly connected and communicate. So, once the node is not working the communication will not be stop but the maintenance and troubleshooting will be difficult in this infrastructure.
It is proved along with lot of benefits and network security ,this infrastructure is having some disadvantages as well. Cabling expense , maintenance cost etc . usually small scale networks do not prefer mesh topology. Small scale and low budget companies can not afford this topology because it is expensive.
Although we do believe that the data security is most important for today's era ,so few companies those wanted to keep their information secure and confidential they must use mesh topology by ignoring the cost incurred for this set up. Data security and integrity would never be compromised by some of the companies.
Mesh topology is more safer, more quick infrastructure which is although very expensive , difficult to mange and maintain. Moreover it is overhead of cabling as well to connect every node but the demand of mesh topology would never be less. It is demanding and appealing topology still.
