VPNs provide flexibility, scalability, and lower costs compared to traditional private networks. A VPN allows connectivity on a shared infrastructure like the internet while maintaining private network policies and performance. Common types are access VPNs for remote access, intranet VPNs for connectivity between corporate offices, and extranet VPNs for connections to business partners. VPNs use tunneling and encryption protocols to securely transport network traffic across public or untrusted networks.

This document provides an overview of wide area network (WAN) concepts and technologies for connecting networks. It discusses WAN purposes and operations, as well as both private and public WAN infrastructures. Private WAN options include dedicated technologies like leased lines, frame relay, and MPLS. Public WAN options rely on broadband technologies like DSL, cable, and wireless, secured using VPNs. The document aims to help readers select appropriate WAN services based on business requirements.
Virtual private networks (VPNs) allow users to securely access an internal network from remote locations over a public network like the internet. VPNs use tunneling protocols to encrypt data transmission and make it appear as if the remote computer is part of the private network. There are various VPN implementation methods, including those using IPSec, MPLS, PPTP, or L2TP. MPLS VPNs in particular offer scalability and centralized services like multicast and quality of service controls. VPNs provide security through authentication, encryption, and authorization controls to prevent unauthorized access to internal network resources.
A virtual private network gives secure access to LAN resources over a shared network infrastructure such as the internet. It can be conceptualized as creating a tunnel from one location to another, with Encrypted data traveling through the tunnel before being decrypted at its destination.
A VPN (Virtual Private Network) extends a private network across a public network, such as the
Internet.
A VPN is a network that uses a public telecommunication infrastructure, such as the Internet, to provide
remote offices or individual users with secure access to their organization's network. A VPN ensures
privacy through security procedures and tunneling protocols such as the Layer Two Tunneling Protocol
(L2TP). Data is encrypted at the sending end and decrypted at the receiving end.
There are two main types of virtual networks: virtual private networks (VPNs) and virtual local area networks (VLANs). VPNs use encryption to create a secure "tunnel" between two systems across a public network like the Internet. VLANs split a local area network into logical segments to reduce broadcast traffic. Both VPNs and VLANs serve different purposes due to how they operate and are used on networks.
Networking principles protocols and practiceDAVID RAUDALES
This document describes an introductory textbook on computer networking principles, protocols, and practices. It discusses connecting two hosts by transmitting digital bits over a physical medium such as electrical cables or optical fibers. Specifically, it proposes a simple scheme for transmitting bits by assigning different voltages to represent 1s and 0s. While this scheme conveys the basic idea, it has limitations in reliably transmitting data due to electromagnetic interference that could corrupt the transmitted bits. The document emphasizes using time-sequence diagrams and layer abstractions to model and reason about network communication independent of physical implementation details.

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).
