If you want maintainability, flexibility, and extensibility (and I guess, you do), your design must include encapsulation. How do you do that?
• Keep instance variables protected (with an access modifier, mostly private).
• Make public accessor methods, and force calling code to use those methods rather than directly accessing the instance variable.
• For the methods, use the JavaBeans naming convention of set and get.

The router encapsulates the packet in the appropriate data link frame type for the outgoing data link. The router determines the exit interface after data encapsulation.
No, accessor member functions are a sign of good class design, particularly in terms of data encapsulation.
* addressing * error detection * frame delimiting
Primary functions provided by Layer 2 data encapsulation include data link layer addressing, and the detection of errors via cyclic redundancy check calculations. An additional function is delimiting groups of bits into frames.

abstraction and encapsulation is one of the concepts of OOPs and C is not an OOP [Object Oriented Programming language] obviously abst & encap will not be supported by 'C' Abstraction & encapsulation is a concept of OOP [Object Oriented Programming] But, 'C' is not an OOP whereas it is a POP [Procedure oriented programming], so obviously 'C' does not support abstraction and encapsulation Answer Encapsulation is not inherently supported but it can be emulated in C. The use of static and extern keywords for functions are almost equivalent to your private and public keywords in java (encapsulation). Read up more on those keywords.. Structures become an object's attributes while functions accepting pointers the the said struct become its methods.

a) Identifies pieces of data as part of the same communication b) Ensures that data pieces can be directed to the correct receiving end devices
wrapping up of data and function into a single unit is called encapsulation where polymorphism is the ability to take more than one form
two applications communicating the data
