Hubs are very simple devices that connect network components, sending a packet of data to all other connected devices.
Hubs are relatively basic network connectors that send a packet of data to every other connected device. Compared to a hub, a switch is more intelligent and has the ability to filter and forward data to a specific location. Within various networks, switches are utilized. Nodes of the network are any computers or printers connected to it. A network workstation is a personal computer that is linked to a network (note that this is different form the usage of the term workstation as a high-end microcomputer). Nodes of the network are any computers or printers connected to it. A network workstation is a personal computer that is linked to a network.

Answer:
Query Wizard
Explanation:
We can use the Query Wizard to automatically create a selection query, but in this case, we have less control in our details of the query design, it's the fastest way to create a query, even detect some design errors.
Steps to use the Query Wizard
1) In the Queries group on the Create, click Query Wizard
2) Add fields
3) On the last page of the wizard, add a title to the query
Answer:
Each time you insert a new node, call the function to adjust the sum.
This method has to be called each time we insert new node to the tree since the sum at all the
parent nodes from the newly inserted node changes when we insert the node.
// toSumTree method will convert the tree into sum tree.
int toSumTree(struct node *node)
{
if(node == NULL)
return 0;
// Store the old value
int old_val = node->data;
// Recursively call for left and right subtrees and store the sum as new value of this node
node->data = toSumTree(node->left) + toSumTree(node->right);
// Return the sum of values of nodes in left and right subtrees and
// old_value of this node
return node->data + old_val;
}
This has the complexity of O(n).
