A proxy server is an intermediary between your computer and the internet, providing enhanced security, privacy, and performance. Here's a simplified explanation:

Functions of a Proxy Server:

1. Internet Control: Manage and monitor internet usage.

2. Performance Boost: Cache data to speed up access.

3. Privacy Protection: Hide your IP address for anonymity.

4. Security: Encrypt data and block harmful sites.

Types of Proxy Servers:

1. Transparent Proxy: Reveals itself and your IP.

2. Anonymous Proxy: Hides your IP but identifies as a proxy.

3. Distorting Proxy: Provides a fake IP address.

4. High Anonymity Proxy: Regularly changes IP addresses for maximum privacy.
