Study Notes
Technical and Vocational Livelihood Information and Communication Technology Computer Systems Servicing Quarter 2 Module 4: OSI Layers
- OSI Model (Open Systems Interconnection Model): A layered framework for describing network communication protocols. Consists of seven layers.
- Application Layer (Layer 7): The user interface for internet activities (email, games, file transfer).
- Presentation Layer (Layer 6): Translates application layer commands into universal formats. Handles data encryption and conversion. Examples are JPEG, GIF, TIFF, MPEG.
- Session Layer (Layer 5): Establishes, manages, and terminates sessions between applications.
- Transport Layer (Layer 4): Defines data transmission, error handling, and security. Uses TCP (Transmission Control Protocol) or UDP (User Datagram Protocol).
- Network Layer (Layer 3): Determines the best route for data to reach destination. Defines logical addressing (IP addresses).
- Data Link Layer (Layer 2): Ensures error-free transmission between nodes. Uses Logical Link Control (LLC) and Media Access Control (MAC) to achieve this. Physical addressing is done at this layer.
- Physical Layer (Layer 1): Handles the physical connection (hardware and cabling). Transmits raw bits.
- MODULAR JACK (Ethernet): A type of connector designed for secure and reliable connections, often used in many applications.
- Common Protocols: Hypertext Transfer Protocol (HTTP), HTTPS, Telnet, SSH, File Transfer Protocol (FTP), Trivial File Transfer Protocol (TFTP), Simple Mail Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), Domain Name System (DNS), Network Time Protocol (NTP), Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), Point-to-Point Protocol (PPP), and many others.
Additional Information
- Single Mode: A transmission mode where one device transmits at a time until all information is sent.
- Half Duplex Mode: An alternate transmission method where devices take turns transmitting.
- Full Duplex Mode: A transmission method where devices can transmit and receive information simultaneously.
- Logical Addressing: virtual IP addresses.
- MAC Addresses: Physical addresses that uniquely identify a network interface card.
- IP Addresses: Logical addresses used to identify devices on a network.
- Data Encapsulation: Enclosing data in headers for transmission through the network.
- Fragmentation and Re-assembly: Dividing large packets into smaller pieces for transmission and reassembling them at the destination.
