Answer:
The answer to this question is given below in the explanation section.
Explanation:
The iteration variable begins counting with 0 or 1.
As you know the iteration mostly done in the looping. For example, for loop and foreach loop and while loop, etc.
It depends upon you that from where you can begin the counting. You can begin counting either from zero or from one.
For example: this program counts 0 to 9.
<em>int total=0;</em>
<em>for(int i=0; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
Let's suppose, if you want to begin counting from 1, then the loop should look like below:
<em>int total=0;</em>
<em>for(int i=1; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>

Answer:
A field with a unique value
Explanation:
A primary key is a field (or a collection of fields) that contain a unique data to identify a precise row in a given table. This is used for data retrieval but also to fully identify the row to be edited in case of update.
It can be as simple as an auto-increment counter, a serial number or an email address for example.
It can also be complex and take into account a series of fields, like a combination of a date and a userID, as a simple example. In such case, the date field by itself would occur many times (many entries per day), and the userID would happen also many times (many daily entries by the userID), but the pair (date/userID) would be unique.
Answer:
Assuming that the distance from Chicago Illinois to Copenhagen Denmark is 4200 miles and the speed of light is 186,400 miles per second;
The time difference 10 milliseconds in the session log and the calculated time of 22.5 milliseconds.
Explanation:
The TCP three way handshake connection time is determined by the distance between the connecting hosts and the speed of the link.
If the distance between the hosts is 4200 miles and the link speed is an assumed speed of light 186,400 miles per second, the TCP session time is;
Time = distance/ speed
Time = 4200 / 186400
Time = 0.0225 seconds. = 22.5 milliseconds
But Johnny's TCP session time is 10 milliseconds, therefore Johnny is lying about the source IP address from Copenhagen Denmark.
