Networking concepts 1

Analog data refers to information that is continuous; (normal)

Digital data refers to information that has discrete states (computerized)

Explain what is analog signal and digital signal and explain they move through the network :

Periodic - A periodic signal completes a pattern within a measurable time frame, called a period and repeats that pattern over subsequent identical periods. The completion of one full pattern is called a cycle.

Explain what is non periodic Signal

What is usually Represented in a simple periodic analog signal :

What are Sine Waves made off parameters :

What is called the signal which is made off multiple sine waves :

What is Peak amplitude :

Period Is :

Describe what is frequency :

The Term phase or Phase shift , describes the position of the waveform relative to time 0

What is Wavelength :

Wavelength is usually measured in :

What are time domains and Frequency Domains :

A composite signal is made up of many :

A periodic composite signal can be decomposed into :

Explain the difference of how bandwidth can be expressed :

Analog Data Refers to information that is :

Simple periodic analog signal is represented as a sine wave which cannot be decomposed into simpler signals

A sine wave is made up off

Amplitude of a signal is the absolute value of its highest intensity

Frequency is :

Frequency domains :

What is Bit Rate :

Attuenuation is the :

How do we compensate attenuation in real life scenarios :

What is Decibel

What is Noise and show some examples of noise in theory :

What is Data rate :

Data rate is dependent on

Describe what is the difference between bandwidth and throughout

Bit length = Propagation speed X bit duration

SNR is :

Decibel is negative is attenuated and positive is a signal is amplified

Digital signal can have more than two levels allowing more bits to be sent per level

Period refers to the amount of time , in seconds a signal needs to complete 1 cycle

Frequency refers to the number of periods in 1s
