Networking Media

This emanations from nearby cables cause frequency bands to overlap and make signal compete.

Interference

This issue and receive 360- degree horizontal wireless signals that propagates in all directions.

Omnidirectional antennas.

This fiber optic cable type allows light waves to travel along a single path or in only one mode and it is commonly used for high speed transmission over long distances.

Single-mode Fiber Optic cable

This networking media doesn't use any cables in transmitting data and is not bounded by physical geography.

Wireless Media

This refers to an outer optical glass or plastic coating that surrounds and traps the light in the core by the principle of total internal reflection.

Cladding

This will help shield the core and cladding from damage.

Coating

This issues wireless signals along a single direction that employs high frequencies at wider distances.

Directional antennas

Kinds of Shielding:

Dual shielded Quad Shielded

This is a method by which radio waves a radiated directly towards the earth's surface.

Ground wave propagation

This refers to a wireless medium that is used for unicast communication such as wireless PAN, broadband wireless access or wireless MAN etc and in contrast to radio wave, this doesn't follow the curvature of the earth and requires line of sight in order to work properly.

Microwave

Types or Wireless Medium Technologies

Microwave Infrared Bluetooth

This carries electrical or electromagnetic signals between a transmitter and a receiver.

Networking Media

This Data rate and distance are limited by multiple attachments for each attachment introduces some attenuation and distortion on the line.

Number of receivers

What are the Network Transmission?

Parallel Transmission Serial Transmission

It is a transmission wherein a group of bits are sent simultaneously, but each uses a different channel.

Parallel transmission

What are the connectors used with Fiber Optic Cable?

ST Connector (Straight Tip Connector) SC Connector (Subscriber)

This refers to a twisted pair cable that combines the techniques of twisting wire, cancellation, and shielding.

Shielded Twisted Pair (STP)

Kinds of Networking Media:

Wired Media Wireless Media

These limit the distance traveled by a signal.

Transmission impairments

This is the most widely used standards for serial data communications in which is intended to operate over distances of up to 50 feet and has a communication speed that is equal to or less than 20Kbps.

Serial Cable

It is a transmission, in which data with each bit lining up in a series as the bits are sent over a single wire at a time.

Serial transmission

What are the Fiber Optic Modes?

Single-mode fiber optic cable Multimode fiber optic cable

It is a method by which radio waves radiate upwards from the transmitting antenna of the earth into a direction towards the ionosphere.

Sky Wave propagation

This is commonly knows are "Aerial" and refers to a metallic structure that acts as a transducer which converts electrical energy to electromagnetic energy and vice versa.

Antenna

This refers to signal loss due to impedance.

Attenuation

Higher data rate is achieved by means of a greater signal bandwidth.

Bandwidth

Network Design Factors:

Bandwidth Transmission Impairments Interference Number of Receivers

This is a short-range wireless communication technology that allows devices such as mobile phones, computers, and peripherals to transmit data or voice wirelessly over a short distance.

Bluetooth

It is enclosed by insulating protective coating.

Coaxial Cable

This refers to the innermost section that consists of one or more very thin strands or fibers made of glass or plastic.

Core

What are the parts of Fiber Optic Cables?

Core Cladding Coating Jacket

It refers to an array of port mounted in the rack shelves.

Expandable patch panel

This is a method by which radio waves radiation exceeds 30 MHz up to 300 GHz. IT is used for sound/television broadcasting for radio relay systems and for various mobile systems that operates on a frequency that ranges from 30 to 300 MHz, 300 MHz to 3 GHz, and 3 to 30 GHz.

Space Wave Propagation

This refers to a bundle of extremely thin and cylindrical shaped glass strands surrounded by a concentric layer of glass coating that is cable of conduction modulated light transmissions.

Fiber Optic Cable

This is a wireless medium that is used for short-range communication in a closed area using line-of-sight propagation.

Infrared

It serves as a connector between single or double RJ-45 jacks.

Jack Coupler

This refers to the outermost layer that protects a buffer or a bundle of buffer-coated fibers against moisture, abrasive, crushing and other environmental dangers.

Jacket

This is a method by which radio waves travel from the transmitting antenna to the receiving antenna and in lieu of this the receiving antenna must be located within the radio horizon of the transmitting antenna.

Line of Sight Propagation

What are the types of Wave propagation:

Line of Sight Propagation Method Ground Wave Propagation Method Sky Wave Propagation Method Space Wave Propagation Method

This fiber optic cable type allows light waves to travel into numerous paths through the core of the fiber at various angles and it is often applied to local area networks which encompass a much smaller transmission range.

Multimode Fiber Optic Cable

This serves as an extra room for cables where there isn't much floor space.

Network Rack

Choices of Coaxial Cable Grade:

Polyvinyl chloride Grade(PVC) Plenum Grade

This refers to a twisted pair cabling connection plug.

RJ-45 Connector

This refers to a wireless medium that is used for multicast communications and paging systems over long distances.

Radio Wave

It is a relatively rigid coaxial cable about 1.27 centimeters in a diameter and it uses vampire tap or piercing tap as connectors.

Thick Cable

It is a flexible coaxial cable at about .64 thick. It uses British Naval Connector cable connector attached to the computer's NIC.

Thin Cable

Types of Coaxial Cable:

Thin Cable Thick Cable

It means it could do both ____ and receive signals.

Transceiver

This consist of two insulated strands of copper wire that are arranged in a regular spiral pattern.

Twisted Pair Cable

This is a UTP cable that refers to a twisted pair cable in which pairs cable that contains no shielding.

UnShielded Twisted Pair (UTP)

It is used to support 2 or more couplers.

Wall plate

This is a networking media that uses cables and are limited by the physical geography.
