Study Notes
Data Transmission and Formatting
- Encoding is converting information into another form for transmission.
- Routing is the process of sending a message from source to destination across networks.
- Source, Channel, and Destination are the core elements of communication.
- Segmentation is used to divide large messages into smaller frames for transmission.
- Addressing is crucial for successful message delivery.
- Protocols govern message format, timing, and transmission methods.
- Encapsulation involves placing one format inside another for transmission.
Communication Methods
- Unicast communication sends data to one specific receiver.
- Point-to-point communication sends data to a single network destination.
- Multicast communication sends data to multiple receivers simultaneously.
Network Communication Mechanisms
- Flow control regulates transmission rate to prevent data overload.
- Response timeouts set a limit for expecting a response to avoid delays.
- Collisions occur when multiple devices transmit simultaneously, causing data corruption.
Unicast and Broadcast Communication
- Unicast is one-to-one communication, sending data to a single destination.
- IPv4 utilizes unicast delivery for addressing individual hosts.
- Flow control ensures data transmission is managed to prevent network congestion.
- Message timing encompasses the sequence of message exchange.
- Unicast communication sends data to a single receiver exclusively.
- Broadcast communication aims to reach all devices on a network simultaneously.
- Access methods are protocols that govern how devices share network resources.
Segmenting and Encapsulation
- Segmenting breaks messages into manageable pieces for transmission.
- Numbering segments helps to reassemble them at the destination.
- Protocol Data Units (PDUs) are added to data during encapsulation in the TCP/IP suite.
- Encapsulation involves adding headers and trailers to data as it moves down the stack.
- Decapsulation reverses the process, removing headers and trailers as data moves up the stack.
Organizations and Standards
- IETF (Internet Engineering Task Force) develops and supports TCP/IP protocols.
- Internet Research Task Force (IRTF) focuses on long-term research related to internet and TCP/IP protocols.
- MPEG defines standards for video compression and IPTV.
Network Access Layer Protocols
- Ethernet is the most common LAN access layer protocol.
- Wi-Fi is a wireless LAN protocol frequently used.
TCP/IP and Communication
- TCP/IP (Transmission Control Protocol/Internet Protocol) forms the foundation of the internet.
- Open standards promote interoperability, allowing various devices to communicate.
- Interoperability is the ability of systems to communicate with each other seamlessly.
- Client-server communication uses client applications to request services from server applications.
- Standard organizations develop and promote widespread adoption of communication standards.
- Independence is a key characteristic of standard organizations.
- Non-profit organizations are a common type of standard organization.
