The correct statement about database services or database instances is
( B).<u>An instance of the cloud database operates as a service that handles all application requests to work with the data in any of the databases managed by that instance.</u>
<u />
Explanation:
An instance of the Database Engine can be defined as a service that <u>all application requests to work with the data in any of the databases managed by that instance.The data can be on the same system or can be on another system </u>
So in case of a Cloud based database engine
( B).<u>An instance of the cloud database operates as a service that handles all application requests to work with the data in any of the databases managed by that instance.</u>

Answer:
True.
Explanation:
The statement written in the question is True.We can use one memory location and use it with different values.
For example:- When we are using a loop be it for,while or do-while.The counter that we use for iteration is one and we use that counter to run the loop.We are using a single memory location and we are updating the count in that memory location many times.
for(int i=0;i<1000;i++)
{
//body.
}
We are using i's memory location and changing it 1000 times.
A: Symmetric encryption uses a single key that should be kept secret. The same key is used for both encryption and decryption of data.
Answer:
Provide the basic interface for the hardware.
Explanation:
The time that it takes the computer to receive acknowledgment for a packet is 0.1667 seconds. The time it takes to send out a packet is 4 x 10⁻³seconds
<h3>1 The acknowledgment time for the packet</h3>
speed = 2.4x108m/s
Distance = 40000 km,
Time = distance/ speed
= 40000 x10³/ 2.4x10⁸m/s
= 0.1667
The time that it take is 0.1667 seconds.
b. Number of bytes = 5000
5000x 8 = 40000bits
10 mbps = 10000 kbps
10000 kbps = 10000000
packet size / bit rate = 40000/10000000
= 4 x 10⁻³seconds to send a packet out
