Explanation:

A three way handshake is a method to create a connection between host and server.It is used in a TCP/IP network.

To establish a connection three steps are followed which are as following:-

The host or sender sends a data packet called SYN to the server or receiver.It's purpose is to as if the receiver is open for new connections.
When the receiver receives the SYN packet it responds with an ACK or SYN/ACK packet as a confirmation for the connection.
When the sender receives the SYN/ACK packet and it respond with ACK packet.

Answer:

three-way handshake is a process that is used in a TCP/IP network to make a connection between the server and client.

Explanation: This 3-way TCP, is a three-step process that requires both the client and server to exchange synchronization and acknowledgment packets before the real data communication process starts.

The three-way handshake process is designed in such a way that both ends help you to initiate, negotiate, and separate TCP socket connections at the same time. It allows you to transfer multiple TCP socket connections in both directions at the same time.

Bonjour ma question est: expliquer comment fonctionne une calculatrice qui ne contient pas une pile. Pouvez-vous m'aider?

larisa [96]

Answer:

Tout calculateur électronique ou numérique nécessite une source d'alimentation pour fonctionner, avec son circuit configuré à la porte logique requise liée aux touches d'entrée et à l'écran de sortie.

Explanation:

Les calculatrices sont des appareils utilisés pour les calculs arithmétiques. Au 19ème siècle, les calculatrices étaient mécaniques et n'utilisaient pas de batterie, elles étaient encombrantes et utilisaient des tiges et des engrenages dans leur fonctionnement. Les calculatrices récentes sont électroniques, alimentées par une batterie. Ils comprennent un circuit électronique configuré à sa porte logique requise pour le calcul, un bouton pour l'entrée et un écran pour la sortie du calcul.

Define a function called 'findWordFreq, which takes two parameters. The first parameter, 'text" is an nltk.text.Text object and

MakcuM [25]

Answer:

import os

import nltk

import zipfile

from nltk. corpus import gutenberg

from nltk. text import Text

def findWordFreq(text, word):

textfreq = nltk. FreqDist(text)

wordfreq = nltk.FreqDist(word)

maxfreq = max(textfreq)

return wordfreq, maxfreq

if -_name__ == '__main__':

text = input()

word = input()

if not os.path.exists(os.getcwd() + "/nltk_data"):

with zipfile.ZipFile("nltk_data.zip", 'r') as zip_ref:

zip_ref.extractall(os.getcwd())

os.environ['NLTK_DATA'] = os.getcwd() + "/nltk_data"

text = Text(gutenberg.words (text))

word_freq, max_freq = findWordFreq(text, word)

print(word_freq)

print(max_freq)

Explanation:

The natural language package in python is used to get and analyse word from voice input. The python code above get words from a zipfile extract, and the 'findWordFreq' function gets the word count and the maximum number of alphabet used in the word distribution.

Lisa [10]

Answer:

Two systems are connected by a router. Both systems and the router have transmission rates of 1,000bps. Each link has a propagation delay of 10ms. Also, it takes router 2ms in order to process the packet (e.g. decide where to forward it). Suppose the first system wants to send a 10,000 bit packet to the second system. How long will it take before receiver system receives the entire packet.

Transmission time for first Router = 10,000 bits / 1000 bps = 10 seconds

Receiving time for seond route r= 10,000 bits / 1000 bps = 10 seconds

Propagation delay = 10ms = .01 seconds x 2 for two delays = .02 seconds

First router 2ms to process = .002 seconds

Add all the times together and we get 20.022 seconds which is the same as or 20 seconds and 22 ms
