This document provides an overview of FTP and web servers. It defines an FTP server as software that uses FTP to transfer files between networked computers, facilitating efficient file sharing. Key FTP server features include authentication, file management, transfer modes, and logging. The document also defines a web server as a computer that stores, processes, and delivers web content to clients. Web servers have hardware, software, network, and storage components and function by receiving and responding to client HTTP requests with static or dynamically generated content.

3. Definition:
An FTP server is a software application that uses the File Transfer Protocol (FTP)
to enable the transfer of files between computers on a network.
Purpose:
FTP servers facilitate efficient and secure file transfers, making it easier to share
and manage files across different systems.enable the transfer of files between computers on a
network.
Introduction FTP Server

5. Key Features of FTP Server
 Authentication and access control: FTP servers provide mechanisms to authenticate
users and control access to files and directories based on permissions.
 File management and directory operations: Users can upload, download, rename,
delete, and organize files and directories on an FTP server.
 Transfer modes: FTP servers support both active and passive transfer modes to handle
different network configurations.
 Error handling and logging: FTP servers log important events and errors to help with
troubleshooting and auditing.

6. How FTP Server Works
 The client (using FTP software) connects to the server on port 21.
 The client provides credentials for authentication.
 Once authenticated, the client and server communicate over a control
connection.
 The client sends commands (e.g., GET, PUT) to request file operations.
 The server responds with status codes and messages.
 Data transfer occurs in either active or passive mode.
 Files are transferred between the client and server.
 After the transfer, the client can disconnect using the QUIT command.

7. Introduction WEB Server
Definition:
A web server is a computer or software that stores, processes, and delivers web
content to clients upon request.
Purpose:
A web server is responsible for hosting websites and serving web pages to clients
over the internet. It handles requests from web browsers, retrieves the requested resources,
and sends them back to the client for display.

9. Components Of WEB Server
 Hardware: Web servers require physical infrastructure, such as servers and
storage devices, to store and process web content.
 Software: Web servers rely on specific software components, including an
operating system (e.g., Linux, Windows), web server software (e.g., Apache,
Nginx), and other necessary software.
 Network: Web servers are connected to the internet and have IP addresses and
domain names. They communicate using network protocols like HTTP and
HTTPS.
 Storage: Web servers have a file system where web content is stored, including
HTML files, images, scripts, and other resources required for website functioning.

10. WEB Server Functionality
 Client sends an HTTP request to the web server.
 The web server receives and processes the request.
 If the requested resource is static, the server retrieves and sends it back to
the client.
 For dynamic content, the server executes necessary scripts or interacts with
databases to generate the content.
 The server constructs an HTTP response with the requested content or an
error message.
 The server sends the response back to the client, which processes and
displays the content or error message.
