A LAN, abbreviated from Local Area Network, is a network that covers a small geographical area such as homes, offices, and groups of buildings. Whereas a WAN, abbreviated from Wide Area Network, is a network that covers larger geographical areas that can span the globe.
A Wide Area Network (WAN) operates over a much larger area, as they interconnect LANs to allow them to exchange data.

Answer:
Q=It
and
p=IV
Given, v=9V P= 7W
I=P/V
I =7/9
Also, time(t) from 9am to 12pm is 3hrs
Converting into sec =3×3600
t=10800
Q= 7/9 ×10800
Q =8400C
When two tables share the same primary key, they share a
A. one-to-one relationship.
Explanation:
- One-to-one relationship is a type of cardinality that refers to the relationship between two entities A and B in which one element of A may only be linked to one element of B, or the opposite way.
- A one-to-one relationship in a relational database occurs when one parent record or field has either zero or one child record only.
- These relationships are the easiest to represent in databases because both the parent and child records may be in the same table.
- One-to-one relationships associate one record in one table with a single record in the other table.
- These relationships are frequently used to indicate critical relationships so you can get the data you need to run your business.
- A one-to-one relationship is a link between the information in two tables, where each record in each table only appears once.
