Answer:
Stored procedures or procedures are subroutines or subprograms in SQL written by the user to accomplish a certain task. it helps to mitigate SQL injection by using markers as placeholders for data input and it streams the query statement and data separately in the database.
Explanation:
The stored procedure used in SQL is a user-defined function. Unlike built-in functions like pi(), they must be called to use them.
SQL injection in query statements is written by hackers to bypass conditions, especially when trying to gain access to other user accounts. Stored procedures use markers or placeholders to prevent this.
Answer:
Call tracking system
Explanation:
It helps to measure total amount of visitors per month and based on the volume of visitors, it calculates how many phone numbers should be displayed to show a different number for each clique.
Answer:
The Basic Program is as follows:
10 LENGTH = 50
15 WIDTH = 30
20 AREA = WIDTH * LENGTH
25 PRINT AREA
30 END
The Algorithm is as follows:
1. Start
2. Let Length = 50
3. Let Width = 30
4. Compute Area = Length * Width
5. Display Area
6. Stop
See Attachment for flowchart (flowchart is designed using draw io tools)
Explanation:
The flowchart, algorithm and basic program all follow the same sequence and explanation
Using the basic program as a case study;
Line number 10: The program starts by initializing LENGTH to 50
Line number 15: It then initializes WIDTH to 30
Line number 20: The AREA is calculated by LENGTH * WIDTH
Line number 25: The value of AREA is printed afterwards
Line number 30: Lastly, the program stops execution
<em>The answer is Crimper.
</em>
<em>
</em>
<em>Crimper is a networking device that would allow RJ-45 pins to get attached to UTP(Unshielded Twister Pair), CATs (Category Ns) and STPs (Shielded Twisted Pair) Cables. These are common type of cables used in computer networking. A crimper looks like a pliers only it has narrow ends with a hole where you would put RJ-45 devices together with the cables. In order to make the cable hold on to the RJ-45, the two hands must be squeezed together with an exact force (not too much force). Once the crimper made a sound, that means, your RJ-45 is now locked with the cables inside. </em>
<em>
</em>
<em>You must be very careful when using this device. Sometimes crimpers has blades that could peel off cables or cut them for alignment and proper attachments. A pair of gloves and googles are also advisable to wear when you use this device for safety measures.</em>
