what is the purpose of the domain name system

Answers

Answer 1

Answer:

The Domain Name System (DNS) is a central part of the internet, providing a way to match names (a website you're seeking) to numbers (the address for the website). Anything connected to the internet - laptops, tablets, mobile phones, websites - has an Internet Protocol (IP) address made up of numbers.

Explanation:

Answer 2
The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates more readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. By providing a worldwide, distributed directory service, the Domain Name System has been an essential component of the functionality of the Internet since 1985.

The Domain Name System delegates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain. Network administrators may delegate authority over sub-domains of their allocated name space to other name servers. This mechanism provides distributed and fault-tolerant service and was designed to avoid a single large central database.

A digital computer has a memory unit with 26 bits per word. The instruction set consists of 756 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. a. How many bits are needed for the opcode? b. How many bits are left for the address part of the instruction? c. What is the maximum allowable size for memory? d. What is the largest unsigned binary number that can be accommodated in one word of memory?

Answers

Answer:

a. the number of bits needed for the opcode = 10

b. address part is = 16 bits

c. maximum allowable size of memory = 65536

d. Maximum memory size per word = 67108864

Explanation:

The memory size of the instruction set is 756 which is less than 2^10 (that is 1024).

Since the word size is 26 bits and the instruction takes 10, the remaining 16 is for the address part which is 65536 memory address. The maximum number of memory size for a word is 67108864.

What will be the output of the following lines of code and the user’s response?

>>> answer = input("What does your dog weigh? ")
What do you weigh? 85.7
>>> weight = int(answer)
>>> print("The weight is" , weight)
An error occurs.
The weight is 85.7
The weight is 85
The weight is 86

Answers

Answer:

An error occurs.

Explanation:

You cannot pass a string representation of a float ("85.7") into an int conversion, you'd have to convert it into a float first.

So weight = int(float(answer)) would work.

1. The Bank manager is imposing a 10% interest rate on the new salary loan to every account in the BPI Family Bank. (ANSWER SHOULD BE UPPER CASE OR CAPITAL LETTERS) *

Answers

Hi, you've asked an incomplete question. However, I inferred you want to know the type of accounting activity involved in this process.

Answer:

CALCULATING

Explanation:

The process of imposing a 10% interest rate of course would require calculating how much cash value is to be deducted from the "new salary loan" of the respective accounts in the "BPI Family Bank".

This process in accounting often involves computing the individual loan amount multiplied by the interest percentage. For example, a 10% interest rate on a salary loan of $2000 would be [tex]\frac{10}{100} * 2000[/tex] = $200

Choose the best type of loop for each situation.

1. You are finding the batting average of 13 baseball players.

b- while

2. You are asking your users for the names of all the stores where they shopped to find their friend's birthday
present. They will show they are done by entering the word "done."
a- for
b- while

Answers

Answer:

1. Option A: for loop is correct

2. Option B: while loop is correct

Explanation:

Two loops are used commonly. For and while

For is used when the number of iterations are already known and while is used when number of iterations is not known and the loop has to be terminated based on any condition.

1. You are finding the batting average of 13 baseball players.

For loop will be used as the number of iterations is already known. The score of 13 players has to be used to calculate the average so there will be 13 iterations. Hence, for loop will be used.

2. You are asking your users for the names of all the stores where they shopped to find their friend's birthday  present. They will show they are done by entering the word "done."

While loop will be used as the termination of loop depends on the input given by the user so the number of iterations are not already known.

Hence,

1. Option A: for loop is correct

2. Option B: while loop is correct

Answer: 1.for 2. while

= 15 + 5 × 3 ÷ 14

= 15 + 5 × 3/14

En un taller tienen dos taladros de sobremesa de 600 w de potencia, una sierra de calar de 500 w y cuatro soldadores de 50 w. Los taladros funcionan una media de 2 horas diarias, la sierra de calar 1 hora y los cuatro soldadores funcionan una media de 4 horas diarias. Calcular la energía consumida por todos estos aparatos durante un día.

Answers

Answer:

El consumo del taller es de 3.7 kw/h.

Explanation:

Dado que el taller posee dos taladros de sobremesa de 600 vatios de potencia, que son utilizados durante 2 horas diarias; una sierra de calar de 500 vatios de potencia que es utilizada durante 1 hora diaria, y cuatro soldadores de 50 vatios que se utilizan durante 4 horas diarias, para medir el consumo diario de energía del taller es necesario realizar el siguiente calculo:

600 x 2 x 2 = 2,400 vatios de consumo taladros

500 x 1 x 1 = 500 vatios de consumo sierra de calar

50 x 4 x 4 = 800 vatios de consumo soldadores

2,400 + 500 + 800 = 3,700 vatios de consumo total

Pasado a kilovatios, el consumo del taller es de 3.7 kw/h.

4.20 [5] <§4.5> Add NOP instructions to the code below so that it will run correctly on a pipeline that does not handle data hazards. ADDI X1, X2, #5 ADD X3, X1, X2 ADDI X4, X1, #15 ADD X5, X3, X2

Answers

Answer:

Following are the solution to this question:

Explanation:

The following is the sequence of instructions to ensure proper implementation after adding NOPs:  

[tex]ADDI \ Xl,X2, \#5\\NOP\\NOP\\NOP\\ADD \ X3, X1,X2\\ADDI \ X4, X1, \#15\\ADD \ X5, X3,X2\\[/tex]

The value of the X1 is identified in the first ADDI order X1, X2, #5, mostly on the WB level, which appears in clock cycle five. Before the second instructions, three NOPs are added because as second instruction should wait for X1 to be correct.

Its second primary example with cycle 5, but ends through cycle 9. clock. Since X3 quality doesn't execute its third command, no NOP is inserted.

Its third instruction begins at clock cycle 6 and finishes at clock cycle 10. Because the fourth order is not required to execute an X4 value, no NOP is inserted, and the fourth instruction begins in cycle 7 and finishes at clock cycle 11.
