Inter-VLAN routing is the process of forwarding network traffic from one VLAN to another VLAN using a
router.
VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to
communicate with hosts in another VLAN, the traffic must be routed between them. This is known as
inter-VLAN routing. On Catalyst switches it is accomplished by creating Layer 3 interfaces (Switch virtual
interfaces (SVI)).

Embracing GenAI - A Strategic ImperativePeter 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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Open System
Interconnect (OSI) model
was developed as a way to
help disparate computing
systems communicate with
each other.
It is composed of seven layers that work together in
order for communication to occur. Network devices tend
to fall within the first three of those layers. Layer 1—the
Physical Layer—deals with how bits are converted to
the appropriate signal and placed on the network. Layer
2—the Data Link Layer—is concerned more concerned
with making sure the appropriate host is reached on the
network. Finally, Layer 3—the Network Layer—is all
about making sure the right network is reached.
Network devices I.
6. Page 6
Network devices I.
– The hub.
» Operates at Layer 1 of the OSI model.
• It is only concerned with physically placing the signal on the
network.
» All devices that connect to hubs are in the same collision domain
and broadcast domain.
• Collision domains are areas where network traffic can collide and
cause problems.
• Broadcast domains are network segments where broadcast
traffic is heard by all of the devices on the network.
» A hub functions as a concentrator/repeater in that it doesn’t care
where the signal comes from or where it is going.
» A hub only operates in half-duplex.
• It can be sending or receiving, but not both at the same time.
» All of the network’s bandwidth is shared by all of the devices
connected to the network.
• This sharing of the bandwidth effectively reduces the amount of
bandwidth that is available to devices.
• As the size of the network increases, the performance of the
network will be reduced.
7. Page 7
Network devices I.
– The bridge.
» Operates at Layer 2 of the OSI model.
» Bridges connect different LAN segments together (by creating a
bridge between them) and break up collision domains.
• They can also bridge different types of network media and
different types of network transmissions (e.g., Ethernet to
token ring and/or wireless to Ethernet).
» They have a limited amount of ports.
– The wireless access point (WAP).
» Operates at Layer 2 of the OSI model.
• A specific type of network bridge that bridges wireless
network segments with wired network segments.
» Operates in half-duplex mode by using a method called carrier
sense multiple access with collision avoidance (CSMA/CA).
• With CSMA/CA, devices will listen to the line. If there is no
traffic on the line, the device is free to transmit. If there is
traffic on the line, the device waits a random period of time
and then listens in on the line again.
• While WAPs do not break up collision domains, collisions are
avoided by the use of CSMA/CA.
8. Page 8
Network devices I.
– The switch.
» Operates at Layer 2 of the OSI model.
» It is similar to a hub, but it is also much smarter than a hub.
• It utilizes an application-specific integrated circuit (ASIC) chip.
• The ASIC has specific programing that allows the switch to
learn what devices are on the network and which ports they
are connected to on the switch.
» Because they know which devices are on the segment and
where they are located, they can operate in full-duplex.
• Full-duplex is when a device can send and receive signals at
the same time.
• With full-duplex, all of the devices receive all of the possible
network bandwidth all of the time. They do not share the
bandwidth as in the case of a hub.
» Switches break up collisions domains. Each port on a switch is
its own collision domain.
» Switches do not break up broadcast domains. All devices
connected to a switch will receive network broadcasts.
10. Page 10
Network devices I.
– The modem.
» Operates at Layer 1 of the OSI model.
» The term “modem” is actually short for modulator/demodulator.
• It was originally developed to take the digital signal coming
from a node and convert it to an analog signal (modulating the
signal) to be placed on the wire. In return, it would accept an
analog signal from the wire and convert it (demodulating the
signal) to a digital signal that the node could understand.
» They were originally developed to create connections between
network segments via the public switched telephone network
(PSTN) using the plain old telephone system (POTS).
» Cable modems can be used to connect network segments to
the Internet by translating the network signal into a format that
can be handled by the cable network.
» A modem is not a router.
12. Page 12
Network devices I.
– The router.
» Operates at Layer 3 of the OSI model.
» It is responsible for connecting different networks together.
• It uses special programing to keep track of different networks
and the best possible paths to reach those networks.
» It is not concerned with what hosts are connected to networks.
» They are found at the edges of the network.
» They can connect different types of media together (e.g.,
Ethernet to serial and/or Ethernet to fiber optic).
» Routers break up collision domains.
» Routers break up broadcast domains. Because network
broadcasts are for a specific single network, they cannot pass
through a router interface.
• When a router receives a network broadcast, it just drops the
broadcast (it ignores the broadcast).
13. Page 13
Network devices I.
Hubs work at Layer 1 of the OSI model and function as a
concentrator/repeater. Every packet the hub receives is propagated out all
of its ports. Bridges work at Layer 2 of the OSI model. They are used to
connect network segments together. They can also be used to change
network media. A WAP is a specific type of bridge used to bridge wireless
and wired networks. Switches work at Layer 2 of the OSI model. The ASIC
allows them to know where and what devices are connected to them. The
bridge and the switch break up collision domains.
Topic
Hubs, bridges, and switches.
Summary
“Modem” stands for modulator/demodulator. Modems operate at Layer 1 of
the OSI model. Originally, they translated a digital network signal into an
analog signal that the PSTN could handle and reversed the process when
required. Cable modems translate the network signal into a format that the
cable network can handle.
Modems.
Routers work at Layer 3 of the OSI model. They are used to connect
networks together. They do not care what hosts are connected to a
network—just where that network is located and how to get to it. Routers
break up both collision domains and broadcast domains.
