The document is a chapter from a Cisco networking textbook that covers network access and the physical and data link layers. It includes sections on physical layer protocols and network media like copper, fiber optic and wireless; data link layer protocols; and media access control techniques. The chapter aims to explain how these protocols and services support communication across networks and compares different media access control and logical topologies.

Overview of Spanning Tree Protocol (STP & RSTP)Peter R. Egli
Ethernet networks require a loop-free topology, otherwise more and more broadcastand unknown unicast frames would swamp the network (creation of frame duplicates resulting in a broadcast storm). Spanning Tree Protocol (IEEE 802.1D) and its faster successor RSTP (IEEE 802.1w) provide loop prevention in bridged networks by establising a loop-free tree of forwarding paths between any two bridges in a network with multiple physical paths. If a link fails, STP and RSTP automatically establishes a new loop-free topology. This presentation describes in detail how STP and RSTP work along with typical examples.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.
