POP3 (Post Office Protocol version 3) and IMAP (Internet Message Access Protocol) are both email retrieval protocols used by email clients to access messages from a mail server. POP3 downloads emails from the server to the local device and usually deletes them from the server, making emails accessible only on that specific device. It is simple and uses less server storage, but not ideal for accessing mail from multiple devices. In contrast, IMAP keeps emails stored on the server, allowing users...

 (a) Microkernel Architecture

  • A microkernel is an OS architecture where only essential functions (like process management, memory management, and inter-process communication) run in kernel mode.

  • Other services (like device drivers, file systems, etc.) run in user mode.

  • Advantage: More stable and secure; easier to maintain.

  • Disadvantage: Can be slower due to more user-kernel interactions.

(b) Data Backup Strategies

  • Strategies used to safeguard data from loss or corruption.

    • Password-Based Authentication

      • User logs in with username + password.

      • Common but vulnerable to brute-force and phishing attacks.

    • Multi-Factor Authentication (MFA)

      • Uses 2 or more factors:

        • Something you know (password)

        • Something you have (OTP, token)

        • Something you are (biometric)

      • Much more secure.

    • Biometric Authentication

      • Uses fingerprint, face, iris, or voice.

      • Fast and secure, used in phones and high-security systems.

    • Token-Based Authentication

      • Uses a hardware/software

    Packet switching is a method used in computer networks to transmit data efficiently by breaking it into smaller units called packets. Each packet travels independently across the network and may take different routes to reach the destination. Once all packets arrive, they’re reassembled into the original message.

    🔧 How It Works

    1. Segmentation: The original message is divided into packets.
    2. Header Info: Each packet gets a header with source, destination, and sequencing info.
    3. Independent Routing:
