Study Notes
Network Quality Criteria
- Good networks must meet criteria: Performance, Reliability, Security.
Communication Addresses
- Communication between two parties requires: Source address and Destination address.
Network Topology
- Topology describes the Graphical representation of relationships between all links and devices.
Hybrid Topology
- A network combining different basic topologies (e.g., star ring or star bus) is known as a Hybrid topology.
Protocol Key Elements
- Semantics: Refers to section bits.
- Syntax: Represents the format data takes.
- Timing: Indicates when data is sent and the speed of sending.
Star Bus Network
- A Star bus network connects two or more star topologies using a bus trunk.
Simplex Mode
- In Simplex mode, the entire channel capacity is used to send data in one direction.
Bus Topology Backbone
- A bus topology has a single long cable acting as the backbone linking all devices.
Multipoint Connection
- Multipoint connection: More than 2 devices share a single link.
TCP/IP Layer Addresses
- TCP/IP layer addresses include:
- Network: 32-bit IPv4 address
- Datalink: 48-bit MAC address
- Application: User-friendly address
- Transport: 16-bit port numbers
Star Connection
- In a Star topology, each device has a dedicated point-to-point link to a central hub with no direct device-to-device links.
Star Ring Network
- A Star ring consists of two or more star topologies connected using a multi-station access unit.
Network Categorization
- A network's category is determined by its Size.
Protocol Layering
- Protocol layering divides complex communication tasks among layers governed by specific protocols.
Communication Protocol
- A Protocol is an agreement allowing devices to communicate effectively; without it, they may not communicate despite being connected.
Data Communications
- Data communications involve exchanging data between devices over a transmission medium like cables.
Transmission Medium
- The Transmission medium is the sole physical path a message travels from sender to receiver.
Duplex Modes
- Half duplex: Channel capacity is taken over by the transmitting device at a time.
- Full duplex: Both stations can transmit and receive simultaneously.
Mesh Connection
- Every device has dedicated point-to-point links in a Mesh connection.
Point-to-Point Connection
- A device has a dedicated Point-to-point connection with only the two adjacent devices.
