HTML is a Language while HTTP is a Protocol.

HTML tags are used to help render web pages. The Hypertext Mark-up Language (or HTML) is the language used to create documents for the World Wide Web.

HTTP (Hypertext Transfer Protocol) is a protocol for transferring the hypertext pages from Web Server to Web Browser. HTTP is a generic and stateless protocol which can be used for other purposes as well using extensions of its request methods, error codes, and headers. Basically, HTTP is a TCP/IP based communication protocol, that is used to deliver data (HTML files, image files, query results, etc.) on the World Wide Web.

Convert 1.5GB to KBs = 1500000kb

1500000kb/950kb ≈ 1579

Explanation:

A flash disk is a storage device. It has enough memory to store large files. In the given question, the flash disk has a memory of 1.5GB and can store 1578.94 music files of 950KBs each.

A flash disk is a data storage device that uses flash memory specifically : a small rectangular device which is designed to be plugged directly into a USB port on a computer. It is often used for transferring files from one computer to another computer system.

Flash disks have no mechanical platters or access arms. It is termed "disk" because of the data which are accessed as if they were on a hard drive. The disk storage structure is emulated.

In the given question, the flash disk contains 1.5GB memory and has to store music files of 950KBs each. For determining the number of music files which can be stored in the flash disks, we have to first convert the unit of flash disk from GB to KB:

1GB = 1,000,000 KB

1.5 GB = 1,500,000 KB

size of music file = 950 KB

Number of music files that can be stored = storage in the flash disk ÷ size of the music file

Number of music files = 1500000KB ÷ 950KB

Number of music files = 1578.94

Macro shares language both the computer and the programmer can undestand.

sent = input("")

count = 0

new_sent = ""

for i in sent:

   if count == 0:

       new_sent += i

       count += 1

   else:

       if i.isupper():

           new_sent += " "+i.lower()

       else:

           new_sent += i

print(new_sent)

The above code works if the user enters the sentence.

   count = 0

   new_sent = ""

   for i in sentence:

       if count == 0:

           new_sent += i

       else:

           if i.isupper():

               new_sent += " " + i.lower()

Explanation:

Analyzing the given code segment

In class Dance,

A method named dance was defined with an instance of two string variables/values

which are name and song

public Dance(String name, String s)

In the main of the program,

The first line creates an instance of Dance as dance1

dance1 is initialized with the following string values: "Tango","Hernandos Hideaway"

- The first string value "Tango" will be passed into the name variable of the Dance method

- The second string value "Hernandos Hideaway" will be passed into the song variable of the Dance method

Next, another instance of Dance is initialized as dance2

dance2 is initialized with the following string values: "Swing","Hound Dog"

- The first string value "Swing" will be passed into the name variable of the Dance method

- The second string value "Hound Dog" will be passed into the song variable of the Dance method

On line 3 of the main: System.out.println(dance1.toString());

The values of dance1, which are "Tango","Hernandos Hideaway" are printed

On line 4 of the main: System.out.println(dance2.toString());

The values of dance1, which are "Swing","Hound Dog" are printed

Hence, option d answers the question

You need to order 11100 pizzas.

83 * 1/3 = 28 pizzas

28 = 11100

Let's address the few mistakes in your code so far. First, age is of type string and year is of type int. You're trying to subtract an int by a string and that doesn't work. Also, you have inconsistent quotes "Hello '. You should always use the same type of quote. The (year - age)) isn't properly formatted into the print statement. There is no plus adding it.

Here's my working code:

import datetime

name = input("What is your name? ")

age = int(input("How old are you? "))

year = datetime.datetime.now().year

print("Hello " + name + " you were born in " + str((year - age)))

I just fixed your code. Best of luck.

In python, date and time seem to be not its type of data, but the date and time named module can be imported for it to work with the time and date. So, the program and its description can be defined as follows:

Program Explanation:

Program:

import datetime#import package datetime

name = input("What is your name? ")#defining a variable name that uses an inputs method to input string value

age = int(input("How old are you? "))#defining a variable age that uses an inputs method with the int to input value

year = datetime.datetime.now().year#defining a variable year that takes current value in it

print("Hello " + name + " you were born in " + str((year - age)))#defining a print method that print name value with born year

Non-blocking code does not prevent execution from continuing while blocking code prevents execution from continuing until the operation is complete. Blocking calls hold off on returning until the I/O operation is finished. Synchronous results are returned from it.

Blocking calls hold off on returning until the I/O operation is finished. Synchronous results are returned from it. During the waiting period, nothing else in that process happens. In contrast, a non-blocking call uses a different method to check for completion and returns right away without any results.

Non-blocking code does not prevent execution from continuing while blocking code prevents execution from continuing until the operation is complete. Blocking occurs when subsequent JavaScript in the Node. js process needs to wait until a non-JavaScript activity is finished, according to the documentation for the language.

A program that is non-blocking does not prevent the execution of subsequent operations. Non-blocking techniques run in an asynchronous fashion. Asynchronously refers to the possibility that the program may not always run line by line.
