MÓDULO 1 - Video 1: Topologías y medios de transmisión

Key Takeaways

• Network topology defines the physical structure of device connections, which dictates how data travels, how access is controlled, and how the network responds to hardware failures or cable disconnections.
• The bus topology uses a single shared cable for all devices, making it prone to data collisions and signal attenuation, which historically limited its scalability and overall network performance.
• Token Ring architecture prevents data collisions by using a circulating 'token' that grants exclusive transmission rights to one device at a time, ensuring orderly communication within a closed ring.
• The star topology is the modern standard for local networks, utilizing a central switch to provide dedicated communication channels, which isolates faults to individual devices rather than the entire network.
• Tree or hierarchical topologies organize networks into levels, facilitating easy expansion and logical segmentation, making them ideal for large-scale environments like universities and multi-story corporate buildings.
• Mesh topologies prioritize high availability and fault tolerance by providing multiple redundant paths for data, ensuring that network traffic continues even if specific connections or nodes fail.
• Hybrid topologies integrate multiple network structures to leverage the specific strengths of each, allowing organizations to balance performance, cost, and reliability across complex, large-scale infrastructure.
