Routers connect different computer networks and forward data packets between them by reading the address information in each packet to determine the ultimate destination. A router contains a routing table with information about connected networks and uses this to determine the best path for packets to travel through multiple networks to reach their destination. There are two main types of routers: core routers connect different cities while edge routers connect users and hosts to networks.
Network media refers to the physical paths over which electrical signals travel between network components. There are two types of network transmission: bounded/guided transmission, where signals are confined to a specific path using cables like twisted-pair, coaxial, or fiber-optic; and unbound transmission, which extends beyond cabling and includes radio waves, microwaves, and infrared waves. Unbound transmission provides larger bandwidth and wide area capabilities but operates at very high frequencies.

IP addresses are unique 32-bit numbers assigned to each device on a network. They are typically expressed as four octets in dotted decimal format like 216.183.103.150. There are several types of cables used in networking, including unshielded twisted pair (UTP), coaxial, fiber optic, and shielded twisted pair cables. Proper installation of network cabling requires using the correct cable type and connectors, adhering to wiring standards, and testing cables for errors.
Twisted-pair cable, coaxial cable, and fiber-optic cable are guided media that provide a conduit for transmission. Twisted-pair cable reduces noise through regular twisting of the wire pairs. Unshielded twisted-pair (UTP) cable is commonly used for telephone and Ethernet connections while shielded twisted-pair (STP) provides better noise shielding but is more expensive. Coaxial cable uses a central conductor surrounded by insulating and outer conducting layers to carry higher frequency signals than twisted pair over longer distances.
This document provides information on different types of computer network cables, including coaxial cable, twisted pair cable, and fiber optic cable. It describes the components and specifications of coaxial cables like RG-6 and RG-8. It also discusses the categories of twisted pair cables from Cat1 to Cat7 and their uses. Fiber optic cable is described as consisting of a core, cladding, buffer and jacket to transmit data using light pulses.
Fiber optic cables transmit data using glass strands coated with plastic. Light signals travel through the strands due to total internal reflection off the plastic coating. Fiber optic cables have advantages over copper cables like extremely high bandwidth, security, reliability, and immunity to electromagnetic interference. However, fiber optic cables also have disadvantages such as high initial installation costs, susceptibility to physical damage, and requiring specialized testing equipment.
2.a. Wired Media Type and ExplinationTwisted-Pair CableTwiste.pdfaquazac
2.
a. Wired Media Type and Explination:
Twisted-Pair Cable
Twisted-pair cable is a type of cabling that is used for telephone communications and most
modern Ethernet networks. A pair of wires forms a circuit that can transmit data. The pairs are
twisted to provide protection against crosstalk, the noise generated by adjacent pairs. When
electrical current flows through a wire, it creates a small, circular magnetic field around the wire.
When two wires in an electrical circuit are placed close together, their magnetic fields are the
exact opposite of each other. Thus, the two magnetic fields cancel each other out. They also
cancel out any outside magnetic fields. Twisting the wires can enhance this cancellation effect.
Using cancellation together with twisting the wires, cable designers can effectively provide self-
shielding for wire pairs within the network media.
Two basic types of twisted-pair cable exist: unshielded twisted pair (UTP) and shielded twisted
pair (STP). The following sections discuss UTP and STP cable in more detail.
UTP Cable
UTP cable is a medium that is composed of pairs of wires . UTP cable is used in a variety of
networks. Each of the eight individual copper wires in UTP cable \\is covered by an insulating
material. In addition, the wires in each pair are twisted around each other.
UTP cable relies solely on the cancellation effect produced by the twisted wire pairs to limit
signal degradation caused by electromagnetic interference (EMI) and radio frequency
interference (RFI). To further reduce crosstalk between the pairs in UTP cable, the number of
twists in the wire pairs varies. UTP cable must follow precise specifications governing how
many twists or braids are permitted per meter (3.28 feet) of cable.
UTP cable often is installed using a Registered Jack 45 (RJ-45) connector The RJ-45 is an eight-
wire connector used commonly to connect computers onto a local-area network (LAN),
especially Ethernets.
When used as a networking medium, UTP cable has four pairs of either 22- or 24-gauge copper
wire. UTP used as a networking medium has an impedance of 100 ohms; this differentiates it
from other types of twisted-pair wiring such as that used for telephone wiring, which has
impedance of 600 ohms.
UTP cable offers many advantages. Because UTP has an external diameter of approximately
0.43 cm (0.17 inches), its small size can be advantageous during installation. Because it has such
a small external diameter, UTP does not fill up wiring ducts as rapidly as other types of cable.
This can be an extremely important factor to consider, particularly when installing a network in
an older building. UTP cable is easy to install and is less expensive than other types of
networking media. In fact, UTP costs less per meter than any other type of LAN cabling. And
because UTP can be used with most of the major networking architectures, it continues to grow
in popularity.
Disadvantages also are involved in using twisted-pair cabling, howe.
Network cabling is the medium used to transmit information between network devices. There are several types of cable used in local area networks (LANs) including unshielded twisted pair (UTP), fiber optic, and wireless. UTP is the most common and comes in categories that support different transmission speeds. Fiber optic cable can transmit signals over much longer distances than copper cables. Wireless networks use radio signals, infrared, or lasers to transmit information without cables but have disadvantages related to security and interference. Proper installation of network cables follows guidelines such as leaving slack, testing connections, and labeling cables.

High Speed Cabling for 10 Gigabit Ethernet discusses the need for faster network infrastructures to support emerging applications and higher data transmission speeds. As applications like Gigabit Ethernet become standard on desktops, backbone networks need even higher bandwidth capabilities like 10 Gigabit Ethernet. Cabling systems need to support the lifetime of network equipment, which is approximately 12-15 years. Proper cabling is essential to future proof networks and maximize return on investment.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

What is a Decibel?
A decibel (dB) is a unit used to express relative
differences in signal strength. A decibel is expressed as
the base 10 logarithm of the ratio of the power of two
signals, as shown here:
dB = 10 x Log10 (P1/P2)
where Log10 is the base 10 logarithm, and P1
and P2 are the powers to be compared.
19. What is a Decibel?
Note: Log10 is different from the Neparian
Logarithm (Ln or LN) base e logarithm.
You can also express signal amplitude in dB.
Power is proportional to the square of the
amplitude of a signal. Therefore, dB is expressed
as: dB = 20 x Log10 (V1/V2)
where V1 and V2 are the amplitudes to be
compared.
dBm = dB milliwatt = 10 x Log10 (Power in mW / 1 mW)
10 mW = 10 mW/1mW=10 = 10 dBm = 10 x Log10 (10)

25. Twisted Pair Cables
(also known as 10BaseT). 10BaseT
cabling looks like ordinary
telephone wire, except that it has 8
wires inside
instead of 4
cable cannot exceed 325 feet or 100 m
in length.
Cat5e cable, with a standard
connector, known as an RJ-45
connector.
26. Connecting Twisted Pair Cables
10BaseT cabling is available in different grades or categories. Some grades,
or "cats", are required for Fast Ethernet networks, while others are
perfectly
acceptable for standard 10Mbps networks--and less expensive, too. All new
networks use a minimum of standard unshielded twisted-pair (UTP)
Category 5e 10BaseT cabling because it offers a performance advantage
over lower grades.
Activity 6 10 min
27. Connecting Twisted Pair Cables
The baud rate is the rate at which
information is transferred in a
communication channel. In the serial
port context, "9600 baud" means that
the serial port is capable of transferring
a maximum of 9600 bits per second.
Osama Ghandour Geris
Assiut STEM School
32. The following summarizes the features of UTP cable:
- Speed and throughput—10 to 1000 Mbps - Average cost per node—Least expensive
- Media and connector size—Small - Maximum cable length—100 m (short)
Commonly used types of UTP cabling are as follows:
• Category 1—Used for telephone communications. Not suitable for transmitting data.
• Cat 2—Capable of transmitting data at speeds up to 4 megabits per second (Mbps).
• Category 3—Used in 10BASE-T networks. Can transmit data at speeds up to 10 Mbps.
• Category 4—Used in Token Ring networks. Can transmit data at speeds up to 16 Mbps.
• Category 5—Can transmit data at speeds up to 100 Mbps.
• Cat 5e —Used in networks running at speeds up to 1000 Mbps or 1 Gbps.
• Category 6—Typically, Category 6 cable consists of four pairs of 24 American Wire
Gauge (AWG) copper wires. Category 6 cable is currently the fastest standard for UTP ,
with Cat6 STP data can travel with 10 Gbps .
33. Shielded Twisted-Pair Cable
(STP) cable combines the techniques of shielding,
cancellation, and wire twisting. Each pair of wires is
wrapped in a metallic foil . The four pairs of wires then
are wrapped in an overall metallic braid or foil, usually
150-ohm cable. As specified for use in Ethernet
network installations, STP reduces electrical noise both
within the cable (pair-to-pair coupling, or crosstalk)
and from outside the cable (EMI and RFI).
34. Although STPprevents interference better than
UTP, it is more expensive and difficult to install.
In addition, the metallic shielding must be grounded
at both ends. If it is improperly grounded, the shield
acts like an antenna and picks up unwanted signals.
Because of its cost and difficulty with termination,
STP is rarely used in Ethernet networks. STP is
primarily used in Europe.
37. The following summarizes the features of STP cable:
- Speed —10 to 100 Mbps - Average cost Moderately expensive
- Media and connector size—Medium to large
• Maximum cable length—100 m (short)
When comparing UTP and STP, keep the following points in mind:
• The speed of both types of cable is usually satisfactory for LAN
• These are the least-expensive media for data communication. UTP
is less expensive than STP.
• Because most buildings are already wired with UTP, many
transmission standards are adapted to use it, to avoid costly
rewiring with an alternative cable type.
40. Internal Components of Fiber Optic Cables
- Connectors used with Fiber Optic
Osama Ghandour Geris
41. Single Mode Fiber Optic Cable
has a small diametral core that allows only
one mode of light to propagate. Because of
this, the number of light reflections
created as the light passes through the
core decreases, lowering attenuation and
creating the ability for the signal to travel
further. This application is typically used
in long distance, higher bandwidth runs
by Telcos, CATV companies, and Colleges
and Universities , Ex 1Gps for length of
1000m.
usually 9/125 in construction. This means
that the core to cladding diameter ratio is
9 microns to 125 microns.
Multimode Fiber Optic Cable
usually 62.5/125 in construction.
This means that the core to cladding
diameter ratio is 62.5 microns to 125
microns.
has a large diametral core that allows multiple
modes of light to propagate. So , the number of
light reflections created as the light passes
through the core increases, creating the ability
for more data to pass through at a given time.
Because of the high dispersion and attenuation
rate with this type of fiber, the quality of the
signal is reduced over long distances. This
application is typically used for short distance,
data and audio/video applications in LANs. RF
