Study Notes

Introduction to Networks

  • Computer networks are crucial for personal and professional communication, enabling resource sharing across distances.
  • Networks come in various sizes and complexities, requiring proper maintenance, regardless of their type.
  • Basic network concepts are fundamental for understanding how devices and technologies interact.

Network Topologies, Architectures, and Types

  • Mesh: Every device has a path to every other device.
  • Hybrid: Combines various topologies.
  • Star/Hub and Spoke: All devices connect to a central point, such as a hub or switch.
  • Point-to-Point: Two devices connect directly.
  • Point-to-Multipoint: One initiator, multiple receivers.
  • Ring: Devices are connected in a closed loop.
  • Bus: Devices connect to a single cable.

Common Network Components

  • Workstations: Powerful computers used by end users.
  • Servers: Powerful computers that provide resources to the network.
  • Hosts: Any device on the network taking an IP address.
  • File Server: Stores and manages files.
  • Mail Server: Handles email communication.
  • Print Server: Manages printers.
  • Web Server: Handles web-related activities.
  • Fax Server: Sends and receives fax messages.
  • Application Server: Manages network applications.

Network Types

  • Metropolitan Area Network (MAN): Connects multiple buildings in a city.
  • Wide Area Network (WAN): Spans large geographic areas (e.g., the internet).
  • Personal Area Network (PAN): Connects devices in close proximity.
  • Campus Area Network (CAN): Connects devices in a limited geographical area such as college or corporate campuses.
  • Storage Area Network (SAN): Exclusively for storage traffic

Network Architecture

  • Peer-to-Peer (P2P): All devices are equal, sharing resources, but security can be a challenge.
  • Client-Server: A server acts as an authority to provide services to other (client) computers.

Network Topologies and Components

  • Full Mesh: Every node is connected to every other node.
  • Collapsed Core: Combines the core and distribution layers in one tier.
  • Spine and Leaf: A network architecture optimized for data centers with a fast backbone (spine) and nodes connect to that backbone (leaf nodes).

Traffic Flow:

  • North-South: Between an internal network and the internet, particularly important for security.
  • East-West: Traffic between internal systems, commonly overlooked for security purposes.

Summary

  • This chapter details various network types, providing understanding of different network topologies and components.
  • Different topologies have varying pros and cons. Understanding how these work empowers better selection for specific needs.
