Visualizing how networks break down complex communication challenges into layered architectures that power the internet.
The OSI model's layered approach ensures network tasks can be isolated and managed independently.
Simpler model designed specifically for internet communication, merging multiple OSI layers.
# TCP Client in Python (Transport Layer Example)
import socket
def network_request():
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(('1.1.1.1', 53)) # Example DNS request
client.send(b'GET / HTTP/1.1')
response = client.recv(4096)
print('Bytes received:', len(response))
return response.hex()
network_request()
