Answer:
The correct option is option 4 from the options indicated below:
Explanation:
The options are as given below
1-SELECT customer# FROM customers
UNION
SELECT customer# FROM orders;
2-SELECT customer# FROM orders
MINUS
SELECT customer# FROM customers;
3-SELECT customer# FROM orders
INTERSECT
SELECT customer# FROM customers;
4-SELECT customer# FROM customers
MINUS
SELECT customer# FROM orders;
Option 1 is not correct as it will provide the list of all the customers whether they have placed order or not.
Option 2 is not correct as it will provide the list of customers who have placed order but are not in the customers table. This will return the empty records.
Option 3 is not correct as it will provide the list of customers who have placed the order.
Option 4 is correct as it will provide the list of customers from the CUSTOMERS table which are not in the Orders table. thus the list of customers who have not placed the order yet.

Answer:
A lot can happen, depending on the use of the variable
Explanation:
Lets create a position variable, a common variable in games.
Vector3 position = new Vector3(0, 0, 0);
The above variable initialization creates a new Vector3 object. The Vector3 class contains 3 properties, X, Y, and Z. When you assign the variable 'position' the new Vector3 object, the variable 'position' contains an instance of Vector3 where
X = 0,
Y = 0,
and Z = 0.
The variable 'position' can be used to set the position of a player, or an object.
We can reuse this variable when you want the object or player to move.
position.X = 29
position.Y = -14
position.Z = 47
now the object/player's position is (29, -14, 47).
Variables can be used for basically everything you need in programming, from storing a position, to storing the result of a complex math equation.
Answer:
The answer is below
Explanation :
If a company was using a commercial WAN and a vulnerability appeared that allowed attackers find routing information and therefore be able to eavesdrop on corporate transmissions "It is expected that such a company should try to formulate and establish Virtual Private Networks between corporate sites.
This will ultimately lead to intercepted transmissions to be unreadable. Though such means have been seen as time-consuming."
Answer:
RAID level 5 can be used to compensate a limited number of available disks.
Explanation:
There are two type of RAID
- Software RAID
- Hardware RAID
Software RAID
deliver services form the host.
Hardware RAID
provides hardware services.
RAID has levels
0, 1, 5, 6, and 10
RAID 0, 1, and 5 work on both HDD and SSD media,
4 and 6 also work on both media.
RAID 0 :Striping
In this level minimum of two disks,RAID 0 split the file strip the data.Multiple hard drive are used to split the data.
RAID 1 : Mirroring
In this level Minimum two disk require and provide data tendency.
RAID 5 :Stripping with parity
Parity is a binary data.RAID system calculate the value which system used to recover the data.
Most RAID system with parity function store parity blocks.
RAID 5 combines the performance of RAID 0 with redundancy of RAID 1.
RAID 5 level should minimize the fault tolerance.
