Network Fundamentals
- Networks are collections of interconnected devices that enable data exchange and resource sharing.
- Critical in facilitating communications, from local to global infrastructures.
Key Elements of a Network
- Devices: Include computers, servers, routers, switches, and unique addressing for communication.
- Data Transmission: Occurs via physical (copper cables, optical fibers) or wireless channels (Wi-Fi).
- Copper UTP Connections: Common network cables consisting of twisted copper wires that enhance signal integrity.
IEEE 802.3 Standards (Copper)
- Governs Ethernet technology implementation, ensuring interoperability among devices across manufacturers.
- Specifies various Ethernet types, cable length limits, and transmission rates.
Types of Network Cables
- Straight-Through Cables: Same wiring arrangement on both ends, connecting different devices.
- Crossover Cables: Different wiring arrangement for direct communication between similar devices.
Fiber-optic Connections
- Allow high-speed, long-distance data transmission using light signals.
- More costly and require specialized skills for installation compared to copper cables.
- Two Main Types:
- Single-Mode: Designed for long-distance transmission with minimal dispersion.
- Multimode: Suitable for shorter distances within buildings.
Anatomy of a Fiber-Optic Cable
- Core: Central part for light transmission, made of glass or plastic.
- Cladding: Surrounds the core to retain light signals and reduce loss.
- Jacket: Provides protection and is made from materials like PVC.
Conceptual Models of Networking
- Provide structured frameworks to understand network complexities.
- Two Prominent Models:
- OSI Model: A seven-layer framework enabling efficient technology and protocol integration.
- Application Layer, Presentation Layer, Session Layer, Transport Layer, Internet Layer, and others.
- OSI Model: A seven-layer framework enabling efficient technology and protocol integration.
OSI Model Layers
- Application Layer: Provides services to end-users via protocols like HTTP and FTP.
- Presentation Layer: Handles data representation and conversion.
- Session Layer: Manages communication sessions.
- Transport Layer: Ensures end-to-end communication, featuring TCP and UDP for data transfer accuracy.
- Internet Layer: Responsible for logical addressing and packet routing across networks.
