Answer:
1. Verify transactions independently
.
2. Restricting access to programmers to change programs and data files when there is an error.
Explanation:
- Verifying transactions independently by involving another employee re-entering transactions, then programming the software in order to compare the inputs and search out errors, is an essential control method.By doing this, errors are identified, reducing risk of incorrect transactions.
- When programmers have access to changing data and programs, this indicates a lack of internal control. Unrestricted access enables a programmer include or subtract certain elements of programs which could lead to errors in operations and transactions. There should be proper identification of duties and a programmer should be bound by specific functions, reducing the risk of this type of error.
Answer is: Dispersants
Explanation:
Dispersants keep contaminants (e.g. soot) suspended in the oil to prevent them from coagulating. Anti-foam agents inhibit the production of air bubbles and foam in the oil which can cause a loss of lubrication, pitting, and corrosion where entrained air and combustion gases contact metal surfaces.
So that's why the answer is: Dispersants
Answer:
A disadvantage of the coder’s using encoder software is there is a cost to the software, but savings can be seen in other areas.
Encoding is done to reduce the number of bit to be transmitted and save bandwidth .can be fairly complex and contain some delicate parts. This makes them less tolerant of mechanical abuse and restricts their allowable temperature.
Answer:
Referencial Integrity Contraint
Explanation:
The referential integrity constraint states that the customer ID i.e (CustID) in the Order table must match a valid CustID in the Customer table. Most relational databases have declarative referential integrity. That is to say, when the tables are created the referential integrity constraints are set up so as to maintain the quality of information.
Answer:
a. Establish a theory of probable cause.
Explanation:
Heather now knows the cause, and She is quite experienced. She is now studying the cause, and she is trying to come up with the theory of probable cause now. And as she will be able to come up with the theory, the practical will follow, and she will be able to remove the fault then. And hence the correct option is as mentioned in the answer section.
