NETWORKING

Is the act of transmitting and exchanging information between people, people and objects, and objects and objects through various media and actions.

Is the largest computer network in the world. Its predecessor, Advanced Research Projects Agency Network (ARPAnet), was born in 1969.

Refers to communication between terminal devices through a computer network.

Refer to disturbances in that energy to travel through a medium from one location to another.

Refers to the horizontal distance of a wave from a point to the corresponding point on the next wave.

It refers to a vertical distance from a given point on the wave from the horizontal axis.

It describes the position of the waveform relative to time zero

It is a measurement of the delay of the wave relative to some fixed reference point or another sine wave.

It refers to the number of waves made per second or as cycles per second.

This refers to the amount of time (expressed in seconds) required to complete one (1) full cycle.

It is a wave in which both the amplitude and time continuously vary over their respective intervals that results in a wavy characteristic.

€“ It is a wave with several discrete (jumpy) states, such as high or low, and on or off. It has fixed amplitude, but its pulse width and frequency can be changed.

Computers facilitate information exchange and resource sharing from one location to another through some sort of wiring/cabling or waves that act as a physical path, which carries electrical or electromagnetic signals between a transmitter and a receiver.

These networking media use cables and are limited by physical geography

Is a connection wherein data flows in one (1) direction only (unidirectional). This type is either transmit-only or receive-only

These networking media do not use any cables in transmitting data and is not bounded by physical geography.

is a connection wherein data can flow in both directions, but not simultaneously (both at the same time) over a shared physical medium.

Is a connection wherein data simultaneously flows in both directions

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.

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

The most widely used standard for serial data communications is 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.

Refers to two (2) conductors enclosed by an insulating protective coating.

It is a flexible coaxial cable about 0.25 inches thick

It is a relatively rigid coaxial cable about 0.5 inches in diameter. It uses vampire tap or piercing tap as connectors

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

Refers to the twisted-wire pairs producing a magnetic field cancellation effect, which limits signal degradation caused by interference from nearby twisted pairs.

Refers to a bundle of extremely thin and cylindrically shaped glass fibers surrounded by a concentric layer of glass coating that can conduct modulated light transmissions.

Refers to the innermost section that consists of one (1) or more very thin strands or fibers made of glass or plastic.

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.

Is made from plastic that helps to shield the core and cladding from damage.

Stand as protection for the core against compressive forces or crushing and tension or excessive pulling.

Refers to an outermost layer that protects a buffer or a bundle of buffer- coated fibers against moisture, abrasion, crushing, and other environmental dangers.

Computers also facilitate information exchange and resource sharing from one location to another through waves which act as physical paths that carry current or series of electromagnetic energy pulses at various frequencies.

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

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

Refers to a wireless medium that is used for multicast communications (e. g. Radio and TV broadcasting, wireless local loop, mobile communications, and amateur radio) and paging systems over long distances.

Refers to a metallic structure that acts as a transducer that converts electrical energy to electromagnetic energy (upon transmission of signal) and vice-versa.

It is a method by which radio waves travel from the transmitting antenna to the receiving antenna.

It is a method by which radio waves are radiated directly towards the earth’s surface. It is used for: o Worldwide communications with a frequency that ranges from 3 to 30 kHz and 30 to 300 kHz o Broadcasting with a frequency that ranges from 300 kHz to 3 MHz

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

O It is used for sound/television broadcasting for radio-relay systems and for various mobile systems that operate at a frequency that ranges from 30 to 300 MHz, 300 MHz to 3 GHz, and 3 to 30 GHz.
