HOW A REQUEST ORGINATES FROM CLIENT AND REACHES THE SERVER?

REQUEST FROM CLIENT TO SERVER

A client is the end user(us) who generates a command or request which is in human readable language .. then it is converted into machine readable language that is in domain network system DNS. 
 
DNS changes the request into the IP address where it is present in the server. So, then it searches and sends the request to the right server where the information is present and fetches it out to the user. 

The information reaches DNS in the form of IP address later, it changes to human readable language which we see in our browser.  

client <---------> DNS <--------->server



EXAMPLE:
                 
REQUEST : www.google.com
the DNS then searches and changes it into its IP address 

www.google.com --> 126.xxx.xxx.0


the request is generated with either http/https protocol for safer fetching of details.

 which involves the source IP and destination IP .

once the IP is converted the DNS with the use of protocols.. the fragmentation into packets is generated and routers make it to move correctly without any data lose into the internet.. 

the internet takes these packets and sends to the correct server to fetch the information and the same way back it reaches the user .

THE FLOW IS :

User --> DNS --> IP --> Router --> Internet --> Server
Server --> Response --> Internet --> Router --> User --> Browser displays page

THE DELIVERY MAN

  The Delivery Man – Python List Operations  Introduction Lists in Python are used to store multiple items in a single variable. They are flexible, allowing us to add, remove, update, and manipulate elements easily. In this task, different list operations are performed to simulate a delivery man's workflow. 1. Creating a list and accessing an item items = ["Notebook", "Pencil", "Eraser", "Ruler", "Marker"] print(items[2]) Approach: Indexing Why: Lists use zero-based indexing, so the third item is accessed using index 2. 2. Adding a new item items.append("Glue Stick") print(items) Approach: append() method Why: It adds an item at the end of the list, which is ideal for adding new deliveries. 3. Inserting an item items.insert(2, "Highlighter") print(items) Approach: insert() method Why: Used when we need to add an item at a specific position instead of the end. 4. Removing an item items.remove("Ruler...

EC2 LAUNCHING

  EC2 Step 1: Launch EC2 Instance Go to: AWS Console --> EC2 --> Launch Instance Configure: Name : my-web-server AMI : Amazon Linux 2 (easy for beginners) Instance Type : t2.micro (free tier) Step 2: Key Pair Create or select a key pair. Step 3: Network Settings  Allow these: SSH (port 22) --> for login  HTTP (port 80) --> for web access Step 4: Launch Instance Click Launch Instance Step 5: Connect to Instance Use: EC2 --> Connect --> EC2 Instance Connect (easiest) OR via terminal: with this command. for this you have to download the pem files while selecting the key pair.  ssh -i your-key.pem ec2-user@<public-ip> Step 6: Install Web Server For Amazon Linux: sudo yum update -y sudo yum install httpd -y Step 7: Start Web Server sudo systemctl start httpd sudo systemctl enable httpd Step 8: Add a Web Page echo "Hello from EC2" | sudo tee /var/www/html/index.html Step 9: Get Public IP Go to EC2 d...

SORT A LINKED LIST USING MERGE SORT

  Sort a Linked List using Merge Sort Introduction Sorting a linked list efficiently is a common problem in data structures. Unlike arrays, linked lists do not allow direct access to elements, so algorithms like quicksort are not ideal. Merge Sort is the best choice for linked lists because: It does not require random access It works efficiently with node-based structures Problem Statement Given the head of a linked list: Sort the list in ascending order Return the sorted linked list Example Input: 10 -> 30 -> 20 -> 40 -> 60 -> 50 Output: 10 -> 20 -> 30 -> 40 -> 50 -> 60 Solution Code class Solution: def mergeSort(self, head): if not head or not head.next: return head mid = self.getMiddle(head) next_to_mid = mid.next mid.next = None left = self.mergeSort(head) right = self.mergeSort(next_to_mid) return self.merge(left, right) def getMiddle(self,...
