- An overview of the sections and objectives covered in the chapter, including standard and extended ACL configuration and IPv6 ACLs.
- Examples and configuration instructions for standard, extended, and IPv6 ACLs as well as guidance on troubleshooting ACL issues.
The document discusses point-to-point connections and PPP. It covers configuring HDLC and PPP encapsulation on serial interfaces, how PPP operates to establish links using LCP and negotiate network layer protocols using NCP, and troubleshooting techniques for PPP connectivity issues including using debug commands. The chapter summary reiterates key concepts about serial communications, point-to-point links, HDLC, PPP operation, authentication, and multilink PPP.
This document provides an overview of routing concepts and router configuration. It covers the basic functions of routers, including routing decisions, packet forwarding methods, and building routing tables through directly connected networks, static routes, and dynamic routing protocols. The document also describes how to initially configure a router by setting the hostname, interfaces, and verifying connectivity between networks.
This document discusses device discovery, management, and maintenance. It covers using protocols like CDP and LLDP for network discovery. Device management topics include configuring NTP and syslog, while device maintenance includes backing up configurations, restoring files, and upgrading software and licenses.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
A workshop hosted by the South African Journal of Science aimed at postgraduate students and early career researchers with little or no experience in writing and publishing journal articles.

The simplified electron and muon model, Oscillating Spacetime: The Foundation...RitikBhardwaj56
Discover the Simplified Electron and Muon Model: A New Wave-Based Approach to Understanding Particles delves into a groundbreaking theory that presents electrons and muons as rotating soliton waves within oscillating spacetime. Geared towards students, researchers, and science buffs, this book breaks down complex ideas into simple explanations. It covers topics such as electron waves, temporal dynamics, and the implications of this model on particle physics. With clear illustrations and easy-to-follow explanations, readers will gain a new outlook on the universe's fundamental nature.
Assessment and Planning in Educational technology.pptxKavitha Krishnan
In an education system, it is understood that assessment is only for the students, but on the other hand, the Assessment of teachers is also an important aspect of the education system that ensures teachers are providing high-quality instruction to students. The assessment process can be used to provide feedback and support for professional development, to inform decisions about teacher retention or promotion, or to evaluate teacher effectiveness for accountability purposes.
