Graph theory
What type of graph is STAR? A. Bipartite B. Tripartite C. Mutipartite PS : I know a star graph is bipartite but can't we say that a bipartite graph is also tripartite . I. E. It can be partitioned into 3 independent sets. Similarly , it is mutipartite as well.

Complete lattice and Bounded lattice
Is every Bounded lattice Complete ? Eg : ( { x : 0<=x<= 1} , <= ) This lattice is bounded , but is it complete ? (I have a doubt ; what if we consider irrational no.s as well)

TOC RE REC
A RE language can also be called as Turing Recognizable,Turing Acceptable or Turing Enumerable. And REC can be called as Turing Decidable. Now When we say that a language is Turing Computable, Strictly what we could say that it is RE or REC? (Ofcourse if it is REC then it is RE also) PS : It would be great if you could provide some reliable source for it.

DCFL or CFL
{w| number of Zeros=number of Ones} Alphabet= {0,1} It is a CFL for sure. But,is it also a DCFL i.e. can we construct a DPDA for it? My Approach:: for 0 push in stack , for 1's pop ---> In end stack should be empty Hence, a DCFL. But, eg given string :: 1100 Now,for 1's pop but, nothing in stack to pop .... STUCK HERE !!

Fragmentation
In both IPv6/4 reassembly is done only at the destination. Can anyone provide a Reliable source or reference for this ?? I found this :https://blog.apnic.net/2016/01/28/evaluating-ipv4-and-ipv6-packet-frangmentation/ which says : Evaluating IPv4 ... the pack onward, fragmenting as required. Above implies that Defragmentation can also be done at intermediate routers in case of IPv4.

Complete Binary tree
What exactly is a Complete Binary Tree? Different sources provide different definitions: Source 1 : A complete binary tree of depth d is the strictly binary tree all of whose leaves are at level d. http://faculty.cs.niu.edu/~mcmahon/CS241/Notes/ ... which case they call this type of tree an almost complete binary tree or nearly complete binary tree. Which definition to follow ?
