A professional educational institution maintains a dedicated web server and database cluster that hosts an exam results portal for modules undertaken by its students. The resource is idle for most of the learning cycle and becomes excessively busy when exam results are released. How can this architecture be improved to be cost-efficient

Answer:

The three elements that make up the number's 32 bit single precision IEEE 754 binary floating point representation:

Sign (1 bit) = 0 (a positive number)

Exponent (8 bits) = 0111 1100

Mantissa (23 bits) = 000 0000 0000 0000 0000 0000

Explanation:

1. First, convert to the binary (base 2) the integer part: 0.

Divide the number repeatedly by 2.

Keep track of each remainder.

We stop when we get a quotient that is equal to zero.

division = quotient + remainder;

0 ÷ 2 = 0 + 0;

2. Construct the base 2 representation of the integer part of the number.

Take all the remainders starting from the bottom of the list constructed above.

0(10) = 0(2)

3. Convert to the binary (base 2) the fractional part: 0.125.

Multiply it repeatedly by 2.

Keep track of each integer part of the results.

Stop when we get a fractional part that is equal to zero.

#) multiplying = integer + fractional part;

1) 0.125 × 2 = 0 + 0.25;

2) 0.25 × 2 = 0 + 0.5;

3) 0.5 × 2 = 1 + 0;

4. Construct the base 2 representation of the fractional part of the number.

Take all the integer parts of the multiplying operations, starting from the top of the constructed list above:

0.125(10) =

0.001(2)

5. Positive number before normalization:

0.125(10) =

0.001(2)

6. Normalize the binary representation of the number.

Shift the decimal mark 3 positions to the right so that only one non zero digit remains to the left of it:

0.125(10) =

0.001(2) =

0.001(2) × 20 =

1(2) × 2-3

7. Up to this moment, there are the following elements that would feed into the 32 bit single precision IEEE 754 binary floating point representation:

Sign: 0 (a positive number)

Exponent (unadjusted): -3

Mantissa (not normalized):  1

8. Adjust the exponent.

Use the 8 bit excess/bias notation:

Exponent (adjusted) =

Exponent (unadjusted) + 2(8-1) - 1 =

-3 + 2(8-1) - 1 =

(-3 + 127)(10) =

124(10)

9. Convert the adjusted exponent from the decimal (base 10) to 8 bit binary.

Use the same technique of repeatedly dividing by 2:

division = quotient + remainder;

124 ÷ 2 = 62 + 0;

62 ÷ 2 = 31 + 0;

31 ÷ 2 = 15 + 1;

15 ÷ 2 = 7 + 1;

7 ÷ 2 = 3 + 1;

3 ÷ 2 = 1 + 1;

1 ÷ 2 = 0 + 1;

10. Construct the base 2 representation of the adjusted exponent.

Take all the remainders starting from the bottom of the list constructed above:

Exponent (adjusted) =

124(10) =

0111 1100(2)

11. Normalize the mantissa.

a) Remove the leading (the leftmost) bit, since it's allways 1, and the decimal point, if the case.

b) Adjust its length to 23 bits, by adding the necessary number of zeros to the right.

Mantissa (normalized) =

1 000 0000 0000 0000 0000 0000 =

000 0000 0000 0000 0000 0000

12. The three elements that make up the number's 32 bit single precision IEEE 754 binary floating point representation:

Sign (1 bit) = 0 (a positive number)

Exponent (8 bits) = 0111 1100

Mantissa (23 bits) = 000 0000 0000 0000 0000 0000

The operating system allows many users to use the programs which are running concurrently on a single network server. It is the computer operating system that would be best for a large corporation. An example is UNIX.

Answer:

end user

Explanation:

An end user refers to a person using a computer system to perform routine tasks such as listening to music, formatting a document, creating graphic designs, surfing the web, etc., rather than perform systems administration. Thus, an end user is the individual for whom a software application or computer system is created for, especially to perform basic or routine tasks.

For example, a network or system administrator is saddled with the responsibility of implementing changes on an end user's network and network devices in order to get an optimum level of performance.

Answer:

[tex]a = (b + c)/(2 * c)[/tex]

[tex]z = x/(y + c)[/tex]

[tex]c = (9 * c + 32)/5[/tex]

Explanation:

Required

The expression in basic

To do this, we use () to group items, / as divide and * to combine factors

So, we have:

[tex](a)\ a = \frac{(b + d)}{2c}[/tex]

In basic, it is:

[tex]a = (b + c)/(2 * c)[/tex]

[tex](b)\ z = \frac{x}{y + c}[/tex]

In basic, it is:

[tex]z = x/(y + c)[/tex]

[tex](c)\ c = \frac{9c + 32}{5}[/tex]

[tex]c = (9 * c + 32)/5[/tex]

Answer:

Vulnerability scanner

You require a "vulnerability scanner" to provide you with the information to be able to identify the services running on a set of servers on your network.

Vulnerability scanning, commonly known informally as 'vuln scan,' is an automated technique for finding network, application, and security problems ahead of time. The IT department of a company or a third-party security service provider often does vulnerability scanning. Attackers use this scan to find points of access to your network.

A vulnerability scanner can provide features that a port scanner cannot: sending notifications when new systems are connected to the network.

If you want to be able to identify the services running on a set of servers on your network then you need a "vulnerability scanner" to equip you with the details.

Answer:

The correct answer is "Consistency".

Explanation:

Thus, the above is the correct answer.

Answer:

base station is the answer

Answer:

n/2

Explanation:

A linear search starts at the beggining of the array at index 0 and searches for the specific element by analyzing one element at a time. Meaning that if it does not exist in index 0 it moves to index 1 and if its not there it moves to index 2 and so on. If the element is not present in the array it finishes the array and ends, otherwise if it finds the element the search automatically ends. This means that on average the search would end early half of the time. This would mean that on average a total of n/2 elements are visited using a linear search.

Answer:

offline backup solution

Explanation:

In such a scenario, the best option would be an offline backup solution. This is basically a local and offline server that holds all of the flight record data that the cloud platform has. This offline backup server would be updated frequently so that the data is always up to date. These servers would be owned by the aviation company and would be a secondary solution for the company in case that the cloud platform fails or the company cannot connect to the cloud service for whatever reason. Being offline allows the company to access the database regardless of internet connectivity.

Answer:

The SQL queries are as follows:

1. select * from customer

select * from sale

select * from product

2. select name, sex from customer

3. select * from customer where sex = 'male'

4. select name, age from customer where sex = 'male'

5. select name, price, color from product

Explanation:

Given

Tables: customer, sale, product

Required

Answer question 1 to 5

(1) All data in the given tables

To do this, we make use of the select clause to retrieve data from each of the table and * to select all data.

So, we have:

select * from customer --> This lists all data from customer table

select * from sale --> This lists all data from sale table

select * from product --> This lists all data from product table

(2) Selected details from customer table

In (1), we have:

select * from customer --> This lists all data from customer table

To retrieve selected details, we replace * with the field names.

So, we have:

select name, sex from customer

(3) Male customers

In (1), we have:

select * from customer --> This lists all data from customer table

To retrieve male customers, we introduce the where clause

So, we have:

select * from customer where sex = 'male'

(4) Name and age of male customers

In (3), we have:

select * from customer where sex = 'male'

To retrieve the name and age, we replace * with name and age. So, we have:

select name, age from customer where sex = 'male'

(5) Name, price and color of products

In (1), we have:

select * from product --> This lists all data from product table

To retrieve selected details, we replace * with the field names.

So, we have:

select name, price, color from product

Answer:

Estimated Time of Arrival.

Answer:

The program in Python is as follows:

#1

d = int(input("distance: "))

n = int(input("n: "))

arith_prog = []

for i in range(1,n+1,d):

   arith_prog.append(i)

print(arith_prog)

#2

d = int(input("distance: "))

m = int(input("m: "))

n = int(input("n: "))

arith_prog = []

for i in range(m,n+1,d):

   arith_prog.append(i)

print(arith_prog)

#3

r = int(input("ratio: "))

n = int(input("n: "))

geom_prog = []

m = 1

count = 0

while(m<n):

   m = r**count

   geom_prog.append(m)

   count+=1

print(geom_prog)

Explanation:

#Program 1 begins here

This gets input for distance

d = int(input("distance: "))

This gets input for n

n = int(input("n: "))

This initializes the list, arith_prog

arith_prog = []

This iterates from 1 to n (inclusive) with an increment of d

for i in range(1,n+1,d):

This appends the elements of the progression to the list

   arith_prog.append(i)

This prints the list

print(arith_prog)

#Program 2 begins here

This gets input for distance

d = int(input("distance: "))

This gets input for m

m = int(input("m: "))

This gets input for n

n = int(input("n: "))

This initializes the list, arith_prog

arith_prog = []

This iterates from m to n (inclusive) with an increment of d

for i in range(m,n+1,d):

This appends the elements of the progression to the list

   arith_prog.append(i)

This prints the list

print(arith_prog)

#Program 3 begins here

This gets input for ratio

r = int(input("ratio: "))

This gets input for n

n = int(input("n: "))

This initializes the list, geom_prog

geom_prog = []

This initializes the element of the progression to 1

m = 1

Initialize count to 0

count = 0

This is repeated until the progression element is n

while(m<n):

Generate progression element

   m = r**count

Append element to list

   geom_prog.append(m)

Increase count by 1

   count+=1

This prints the list

print(geom_prog)
