Explanation:
An Academic Database deals with the information pertaining to the records of students of an institute. The various fields which can be associated with a student are Name, Unique Identification Number, Marks in various subjects, Grades, Courses Taken and so on. Most of the fields mentioned above have some or other form of validation that is required for the DB to be consistent and follow the basic properties of a database.
One field where range validation can be used is MARKS. In the marks field, the range of marks will be say 0 to 100 and anything below 0 or above 100 must be reported to the database administrator. Another field where we can apply a range validation is AGE in which the range of age allowed could greater than say 10, if it is a college and maximum age could be say 60. Thus, the range check on the AGE field is 10 to 60.
One field where choice validation can be used is GENDER. In the gender field, there could be multiple choices like Male, Female and Others. Thus, out of the available choices we have to select only the available choice and only one choice must be selected where we can apply choice validation. Another field is COURSE, where we can have a list of courses a student can opt for and out of the available courses can select one.
Thus, there are multiple fields where we can apply various types of validation and it is important to explore the area for which the DB has been created understanding all the scenarios and attributes of the problems that are associated with that area.
Answer: Data hazards are the factor behind the damage/problem created in the data of the CPU . There are three types of data hazards which are as follows:-
By considering two element "A" and "B"
- RAW(Read after write)- If the element A tries to read the value before the element B has written it then element A will receive the previous value which is accordingly incorrect .
- WAR(Write after read)-Element B write a value for element A which not read by it.So, it incorrectly gets a new destination assigned.
- WAW(Write after write)-Element B tries to write the value for the element A before element A writes it, thus creating a hazard.
Answer:
she loaned 750 dollars.
it took her 9 months to repay it.
it was 275 days since she took out the loan.
the interest rate was 47% per year compounded daily.
the daily interest rate would be 47% / 365 / 100 = .0012876712 per day.
this assumes 365 days in a year, which is the standard assumption that i know of.
the future value of 750 for 275 days would be based on the formula of f = p * (1 + r) ^ n
f is the future value
p is the present value
r is the interest rate per time period (days in this case)
n is the number of time periods (days in this case).
the formula becomes:
f = 750 * (1 + .0012876712) ^ 275
solve for f to get:
f = 1068.440089.
that's the future value of the loan.
it's what she owes.
the interest rate on the loan is that value minus 750 = 318.440089.
that's how much extra she needs to pay in addition to whatever fees she was charged.
Answer:
1. DMZ (Demilitarized zone)
Explanation:
In computer networking, a Demilitarized Zone is a physical or logical network designed to give an extra layer of security on the organization’s private network. The DMZ acts as an interface between an untrusted network such as the internet and the organization’s internal network. When a server is set up in a demilitarized zone, users can reach it via its public IP address. In case there is an attack on the server, the private network is still protected.
