Answer: star topology.
Explanation:
The layout of the way how the computers in a netword are interconnected is called network tipology.
Some types of network topologies are:
1) Point-to-point tipology: all the computers are connected to each other directly (computer-to-computer, in pairs, this is a direct link between each two computers).
2) Bus topology: all the nodes (computers or server) are connectect to a maing cable.
3) Star topology: all the computers are connected to a central computer or server which is called central hub. This is the layout described in the question.
4) Ring topology: the computers are connectec in a circular path; each computer is connected to the next computer.
5) Mesh: every computer is connected to every other computer.
Answer:
The number of invoices for each vendor that have a larger balance due than the average balance due for all invoices.
Explanation:
This part of the code below
WHERE InvoiceTotal - PaymentTotal - CreditTotal >
(SELECT AVG (InvoiceTotal - PaymentTotal- CreditTotal)
FROM Invoices)
gives the condition to pick the invoices with balance that are greater than the average balance for all invoice.
This part of the code below
GROUP BY VendorName
ORDER BY BalanceDue DESC;
then enables the program to group the result of the above condition by VendorName and sort the resulting rows in the order of BalanceDue. You will therefore, obtain for each row in the NumberOfInvoices column, the number of invoices for each vendor that have a larger balance due than the average balance due for all invoices.
Taking data and instructions from a user, processing the data as per instructions, and displaying or storing the processed data, are the four major functions of a computer. These functions are also known as the input function, process function, output function, and storage function, respectively.
