Answer: Option (c) is correct
Explanation:
PDF is portable document format that come in form of file format .It is used for sharing and transmitting between computing and operating systems for viewing and printing in actual page layout. They can be used fro eBooks ,scanned document and text etc.

- Thus, the correct option is option(c)
Answer: all the answers are correct
Explanation:
Partial mesh networks is simply a packet switching networks which is connected and require that there should be establishment of a circuit before the exchange of packets.
Partial mesh networks are less expensive to implement when they're being compared to the full mesh networks and are also less redundant.
The correct statements regarding partial mesh networks are:
•the number of links connecting nodes in a partial mesh network depends upon the availability and reliability requirements of the network
• switches play an integral role in a partial mesh network, where several paths through the network are available
• redundant links and switches are used to improve the availability and reliability of partial mesh networks
Answer:
many forms
Explanation:
Polymorphism is a construct in object oriented programming which means multiple forms.For example: Suppose I have a function which performs the add operation on two integers and another function with the same name which concatenates 2 given strings:
- string add ( string a , string b)
The two functions represent polymorphic forms of the add function. The function to be invoked at runtime is determined by the runtime argument type.
For example , add (2,3) will invoke int add ( int a, int b);
Similarly, add("hello","world") will invoke string add ( string a , string b);
