    Study Notes

    • The OSI Model is a standard for understanding host-to-host communication between computers.
    • Developed by the International Organization for Standardization (ISO), it consists of 7 layers.
    • The OSI Model simplifies understanding of data transfer and aids in standardization of network devices.
    • Seven layers in the OSI Model:
      • Application Layer: Interacts with the user and provides services for applications.
        • HTTP: for web browsing.
        • FTP: for uploading and downloading files.
        • SMTP: for sending emails.
        • POP3: for receiving emails.
        • Telnet: for remote login.
        • DHCP: for automatically assigning IP addresses.
        • DNS: for translating domain names to IP addresses.
      • Presentation Layer: Deals with data compression, encoding, decoding, encryption, decryption, and data format definition.
      • Session Layer: Maintains distinctions between data from separate applications.
