AI/ML Google Collab - Mounting Google Drive onto Google Collab

 To mount the Google drive on to Collab, 

from google.colab import drive

drive.mount('/content/drive')

Now after this the file can be accessed like this below 

In this case below, The MyDrive is the folder 

from os.path import exists

project_folder='/content/drive/MyDrive/TestFiles/Project_data.zip'

import zipfile

file_exists = exists(project_folder)

print("File Exists ", file_exists)

with zipfile.ZipFile(project_folder, 'r') as zip_ref:

    zip_ref.extractall('Project_data')

What is a TFTP Server

 TFTP (Trivial File Transfer Protocol) is a simplified version of FTP (File Transfer Protocol). It was designed to be easy and simple. TFTP leaves out many authentication features of FTP and it runs on UDP port 69. As it is very lightweight, it is still used for different purposes.

TFTP is used in places where you don’t need much security. Instead, you need a way to easily upload files to and download files from the server. CISCO devices use TFTP protocol to store configuration files and CISCO IOS images for backup purposes. The network boot protocols such as BOOTP, PXE etc uses TFTP to boot operating systems over the network. Thin clients also use TFTP protocol for booting operating systems. Many electronics circuit boards, microprocessors also use TFTP to download firmware into the chip. Overall, TFTP has many uses even today.
