singly linked list stores only the address of next node while doubly linked list stores the address of previous node and next node and hence it is called doubly linked list.
In singly linked list only forward traversing is possible while in doubly linked list forward and backward traversal is possible.

What is a singly linked linear list?
A singly linked list is a linked list which only provides links in "one direction". Using a metaphor, a singly linked list is a one way street, while a doubly linked list is a two way street. Once you move forward in a singly linked list, there is no way to go backwards unless you kept your reference/pointer from before. A singly linked list would look like this: start ----> node1---->node2---->node3 ----> NULL You will see that node2 only has a link forward to node3 - it does not have a link backwards to node1, even though node1 has a link forwards to node2. To prevent us from permanently losing access to portions of the linked list, we generally keep a reference/pointer to "start". A doubly linked list would have twice the number of pointers/references as a singly linked list - making it very inefficient to store small datatypes. On the other hand, it would be possible to move both forwards and backwards with a doubly linked list because you have links pointing both forwards and backwards.
Does each node in a doubly linked list contain a link to the previous as well as the next node?
Yes, each node in a doubly linked list contain a link to the previous as well as the next node. That is the definition of the doubly linked list.
What is the advantage of doubly linked list over Doubly linked list?
A doubly linked list can be traversed in both directions (forward and backward). A singly linked list can only be traversed in one direction. A node on a doubly linked list may be deleted with little trouble, since we have pointers to the previous and next nodes. A node on a singly linked list cannot be removed unless we have the pointer to its predecessor. On the flip side however, a doubly linked list needs more operations while inserting or deleting and it needs more space (to store the extra pointer).
What are the major differences between PDLC and SDLC?
See the graph in the related link. It clearly separates out the differences between PDLC and SDLC.
What is difference between linked list and singly linked list?
Answersingly linked list has the node inserted only at one end. and the pointer corresponds to the next pointer.but in a doubly linked list, the node pointer points to the both previous and the next node.singly linked list has two nodesdoubly linked list has three nodesA doubly linked list makes sense when you need to traverse the list in both directions. You aren't able to do that with a singly linked list.

What is the Lewis structure of CH2ClCOO?
The Lewis dot structure starts with two singly bonded C atoms. On the left hand side C are three singly bonded H atoms. On the right C, there is a doubly bonded O atom to the top and a singly bonded O atom to the right. The upper O has two pairs of dots and the right has three pairs of dots.
