1. An extensive telecommunications infrastructure is provided by a structured cabling system,
which is a complete system of cabling and related components. This infrastructure is used for a
variety of purposes, including phone service provision and data transmission across computer
networks. It shouldn't be hardware-reliant. A structured cabling system is further defined in
terms of ownership. At the termination of the service provider (SP), the structured cabling
system starts. The demarcation point (demarc) or network interface device is at this location
(NID). For instance, in the establishment of a telephone system, the SP provides one or more
service lines (per customer requirements). At the line of demarcation, the SP joins the service
lines. 1.1 Explain the significance of structured cabling and the advantages of structured cabling.

Low-cost wireless mesh communications based on openWRT and voice over interne...IJECEIAES
Technology makes it easier for us to communicate over a distance. However, there are still many remote areas that find it difficult to communicate. This is due to the fact that communication infrastructure in some areas is expensive to build while the profit will be low. This paper proposes to combine voice over internet protocol (VoIP) over mesh network implemented on openWRT router. The routers are performing mesh functions. We set up a VoIP server on a router and enabled session initiation protocol (SIP) clients on other routers. Therefore, we only need routers as a means of communication. The experiment showed very good results, in the line-of-sight (LOS) condition, they are limited to reception distances up to 145 meters while in the non-lineof-sight (NLOS) condition, they are limited to reception distances up to 55 meters.

Hybrid topologies combine two or more topologies.
Course Code: CSE 317 discusses three main types of network cables: coaxial cable, twisted-pair cable, and fiber-optic cable. Coaxial cable uses a central copper conductor surrounded by insulation and shielding, and was first used commercially in the 1940s. Twisted-pair cable uses two insulated copper wires twisted around each other to reduce interference, and comes in unshielded and shielded versions. Fiber-optic cable contains glass cores that transmit data as light pulses and can carry signals hundreds of miles faster than other cables.

Artificial Intelligence (AI) has revolutionized the creation of images and videos, enabling the generation of highly realistic and imaginative visual content. Utilizing advanced techniques like Generative Adversarial Networks (GANs) and neural style transfer, AI can transform simple sketches into detailed artwork or blend various styles into unique visual masterpieces. GANs, in particular, function by pitting two neural networks against each other, resulting in the production of remarkably lifelike images. AI's ability to analyze and learn from vast datasets allows it to create visuals that not only mimic human creativity but also push the boundaries of artistic expression, making it a powerful tool in digital media and entertainment industries.
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).

Devices and Technologies
This chapter gives an overview of the devices and configurations selected for the
proposed design.
Devices
According to McQuerry (2008), the devices that transmit and/or receive data
through a network segment are network devices. There are various devices used in
the implementation of network design in accordance to the requirements.
Switch
A switch is used to connect several nodes of a network within multiple segments
(Hucaby, 2014). This device works on the 2nd Layer of the OSI Model. Also, this
device transmit data to the recipients except for broadcast traffic to devices with
unknown ports. This device eliminates the remaining segments of a network from
unintended procession of data and is imperative to network security and
performance (Hucaby, 2014).
Router
Lucas (2009) stated that routers are interconnection network devices that send and
receive packets between networks. This type of network device is based on Layer 3
IP addresses and selects the best path for data transmission in a network. This
device, while on the 3rd Layer of the OSI Model, makes network address-based
decisions.
Cable
A cable, also known as a cord, plug, or connector transmits power or data between
devices or positions, which is covered in plastic by one or more wires. A power
cable and data cable are the primary types of computer cables. ... The USB>/a>,
SATA, CAT5, and IDE/EIDE cables are other popular examples of data cables.
5. P a g e | 5
Firewall
According to Sheth & Thakker (2011), a firewall, is considered as a single device,
which imposes the access control policy amongst networks. Firewalls, usually a
standalone device, is an application software based or network embedded device.
IP Phone
IP Telephone, very broadly speaking, is a telephone built to operate with an IP
PBX. However, the prevalence of the SIP standard means that the IP PBX of
today has invariably develop into a SIP-based PBX. This is excellent news for
companies and end-users because it ensures the PBX providers cannot push you to
lock in with their proprietary applications or hardware.
Home Gateway
In computing, a home network gateway connects a residential building's local area
network (LAN) to the Internet. ... The home network hardware can be considered
the heart of home networking system. This hardware includes routers, general
purpose servers, and multi-horned computers, also known as multiple network
adapters.
Servers and Hosts
The host is a node that interacts in a user program, either as a server, a client, or
both. The server is a type of host that provides services to other hosts. Usually, a
server allows connections from clients who request a service feature (Jorge, 2019).
Technologies
This is known as entities for both material and irrelevant, created by the
application of mental and physical effort to obtain some value. In this use,
technology applies to instruments and devices that can be used to solve world
problems.
Access Control Lists
The Access Control List is a policy used in filtering routing protocols, permit or
deny traffic flows, and to redirect traffic based on the set policy. Also, this policy
or rules is processed from top-to-down until it hits the first match. The access list is
then processed only when a condition is met (Suman & Agrawal, 2016).

VLAN
Virtual Local Area Network (VLAN) is a standard of logically segmenting devices
on a network that are physically dispersed (Froom et. Al., 2010). This standard
allows network design to be flexible. Similarly, VLANs broadcast domain borders
on the 2nd layer of the OSI Model. These broadcast Domains are device groups,
that receive broadcast frames created by devices in the group (Kaluve et. Al.,
2008).
Cost Assessment
It must be considered the cost of physical network design and looking for best
alternative design that can meet the budget. Hence, we should analyze the cost of
circuit, internetworking devices, hardware, software, network management, test,
and maintenance. These could be by two steps: request for proposal and selling the
proposal to management
Webcam
A webcam is a video camera that feeds or streams an image or video in real time to
or through a computer network, such as the Internet. Webcams are typically small
cameras that sit on a desk, attach to a user's monitor, or are built into the hardware.
