Why is data processing done in computer?
Answer:
The Data processing concept consists of the collection and handling of data in an appropriate and usable form. Data manipulation is the automated processing in a predetermined operating sequence. Today, the processing is done automatically using computers and results are faster and more accurate.
Explanation:
Data is obtained from sources such as data lakes and data storage facilities. The data collected must be high quality and reliable.By using a CRM, such as Salesforce and Redshift, a data warehouse, the data collected are translated into mask language.The data are processed for interpretation. Machine learning algorithms are used for processing. Their procedure varies according to the processed data (connected equipment, social networks, data lakes).These data are very helpful to non-data scientists. The information is transformed into videos, graphs, images, and plain text. Company members may begin to analyze and apply this information to their projects.The final stage of processing is the use of storage in future. Effective data storage to comply with GDPR is necessary (data protection legislation).La historia de los productos tecnologicos

La tecnología es el conocimiento y el uso de herramientas, oficios, sistemas o métodos organizativos. La palabra tecnología también se usa como un término para el conocimiento técnico que existe en una sociedad.
La demarcación entre tecnología y ciencia no es del todo fácil de hacer. Muchos programas de ingeniería tienen un gran elemento de ciencias y matemáticas, y muchas universidades técnicas realizan investigaciones exhaustivas en materias puramente científicas. La mayor parte de la ciencia aplicada generalmente se puede incluir en la tecnología. Sin embargo, una diferencia fundamental importante es que la tecnología tiene como objetivo "ser útil" en lugar de, como la ciencia en su forma ideal, comprender el mundo que nos rodea por sí mismo. El hecho de que comprender la realidad que nos rodea (sobre todo en forma de leyes y principios universales) sea muy útil para fines técnicos, explica por qué la ciencia y la tecnología tienen grandes similitudes. Al mismo tiempo, existen áreas de conocimiento e investigación en tecnología e ingeniería donde las propias ciencias naturales puras han hecho contribuciones muy limitadas, como la tecnología de producción, la tecnología de la construcción, la ingeniería de sistemas y la informática. En estas y otras áreas de la tecnología, por otro lado, puede haber depósitos de matemáticas, economía, organización y diseño.

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

Calcula l'energia (Kwh) consumida per una màquina de 30 CV que funciona durant 2 hores.
Resposta:
44,76 Kwh
Explicació:
1 cavall = 746 watts
Per tant, 30 cavalls es convertiran en:
30 * 746 = 22380 watts
Temps = 2 hores
La quantitat d'energia consumida s'obté mitjançant la relació:
Energia consumida = Potència * temps
Energia consumida = 22380 watts * 2 hores
Energia consumida = 44760 Wh
A quilowatts (Kwh)
44760 Kwh / 1000 = 44,76 Kwh
4 Two people play a counting game.
The rules of the game are as follows:
The first player starts at 1
Each player may choose one, two or three numbers on their turn and the numbers must be in ascending order
Players take it in turns to choose
The player who chooses "15" loses the game. For example, if the first player chooses three numbers (1, 2, 3) then the second player could choose one number (4), two numbers (4, 5) or three numbers (4,5,6).
The first player then takes another go.
-Write an algorithm using pseudocode that allows two players to play this game.
The algorithm should:
--Alternate between player 1 and player 2
--Ask the player how many numbers they would like to choose, ensuring that this is between 1 and 3
--Display the numbers that the player has chosen Display a suitable message to say --which player has won once the number 15 has been displayed
Answer:
algorithm should:
--Alternate between player 1 and player 2
--Ask the player how many numbers they would like to choose, ensuring that this is between 1 and 3
An algorithm using pseudocode that allows two players to play the game is:
BEGIN Player One num "1"ASCENDING order num;TURN Player One num;TURN Player Two num;INCREMENT IF there is num "15"THENPLAYER losesWhat is a Pseudocode?This refers to the use of plain language to describe the sequence of steps for solving a problem.
Hence, we can see that from the given game rules about the input that is made by a player where he starts at 1 and any player that selects 15 loses the game and there is an increment is displayed in a rough form above.

An aviation tracking system maintains flight records for equipment and personnel. The system is a critical command and control system that must maintain a global availability rate of 99%. The entire system is on a cloud platform that guarantees a failover to multiple zones within a region. In addition to the multi-zonal cloud failover, what other solution would provide the best option to restoring data and rebuilding systems if the primary cloud service becomes unavailable?
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:
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.

If an element is present in an array of length n, how many element visits, on average, are necessary to find it using a linear search
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.

1. An arithmetic progression is a sequence of numbers in which the distance (or difference) between any two successive numbers is the same. This in the sequence 1, 3, 5, 7, ..., the distance is 2 while in the sequence 6, 12, 18, 24, ..., the distance is 6.
Given the positive integer distance and the non-negative integer n, create a list consisting of the arithmetic progression between (and including) 1 and n with a distance of distance. For example, if distance is 2 and n is 8, the list would be [1, 3, 5, 7].
Associate the list with the variable 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

What is the bit pattern (raw binary) of the single precision representation of the decimal number 0.125 following IEEE 754 standard
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

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]
