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.
- Application Layer: Interacts with the user and provides services for applications.
