Study Notes
Local Area Networks (LAN) and Components
- LANs enable communication among computers in a small geographical area.
- Common components include switches, routers, and wireless access points.
- VLANs allow network segmentation without physical separation.
Network Types
- WANs connect multiple LANs over longer distances, utilizing public or private networks.
- VPNs provide secure remote access by encrypting data between the user and the VPN server.
Network Architecture
- Peer-to-Peer (P2P) networks allow direct communication among devices without a central server.
- Client/Server architecture relies on dedicated servers to manage resources and services.
Physical Network Topologies
- Bus Topology connects all devices on a single cable, simple but limited by distance and performance.
- Star Topology has all devices connected to a central hub, offering better performance and easier troubleshooting.
- Ring Topology connects devices in a circular pathway, where data travels in one direction.
- Mesh Topology provides multiple pathways for data, ensuring reliability and redundancy.
- Point-to-Point Topology involves a direct link between two devices, ideal for straightforward connections.
- Point-to-Multipoint Topology connects one device to multiple endpoints, useful in various scenarios.
- Hybrid Topology combines different topologies to suit specific network needs.
Topology Selection
- Choosing the right topology depends on factors like scale, cost, and performance requirements.
Encapsulation and OSI Model
- Encapsulation is the method of encapsulating data into appropriate protocol data units.
- The OSI model consists of seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical, each serving specific functions.
Networking Materials and Standards
- Coaxial, twisted-pair, and fiber-optic cables are common physical media for networking.
- Cable properties include transmission speeds, distance limitations, duplex modes, noise immunity, and frequency range.
- Wiring standards, such as 568A and 568B, ensure consistency in cable installation.
Current Ethernet Specifications
- Ethernet operates on a CSMA/CD protocol to manage data collisions.
- Supports both half-duplex and full-duplex communication modes.
- Ethernet frames are crucial for data transfer, containing source and destination addresses.
Networking Devices
- Common devices include hubs, repeaters, modems, NICs, routers, and firewalls, each serving different roles in network communication.
- Specialized devices like load balancers and IDS/IPS enhance network efficiency and security.
Internet Protocol (IP)
- TCP/IP model breaks down into multiple layers, facilitating diverse communication protocols.
- Data encapsulation standards allow for formatting data for transmission across networks.
IP Addressing
- Hierarchical IP addressing includes unique identifiers for network and device locations.
- IPv4 is transitioning to IPv6 to accommodate increasing internet-connected devices, addressing the limitations of IPv4.### Introduction to Networks
