5.1 Flashcards
The terms been with and – – – – – are often confused
Throughput
Networking professionals need to measure or mean decisions based on bandwidth and throughput characteristics people commonly think bandwidth and throughput are identical but they are
Fundamentally different
To make things complicated the term been with as additional meenings in relation to frequencies electric circuits radar and ———
Other technologies
For today’s networking cabling is typically measured in megahertz or gigahertz which indicates the number of times in a second that an electrical signal can change states. This is known as
Frequency
Wireless in your such as FM radio or Wi-Fi we’re frequency is also measured in megahertz or gigahertz must be contained within a specific range of electromagnetic spectrum to prevent the signal from
Interfering with other shingles using nearby frequencies
The number of lights cycles per minute is example of frequency you’ll see a maximum frequencies identified for different categories of
Copper cabling
When was for today’s network is measured in – – – – or – – – –
MGbs or GBPS
————-refers to the amount of data you could theoretically transmit during a given period of time taking into consideration Factors such as frequency distance signal to noise ratio among others
Band with
Think of bandwidth as the number of lines on the freeway you can increase been with by —————to the freeway
Adding more lanes
Bandwidth refers to the number of – – – – available for data transfer
Lanes
This is also called payload rate or effect of data rate
Throughput
– – – – – – for today’s networks is also measured in megabytes or gigabytes per second
Throughput
Sending data over a Analog signal
Modulation
Converting data into a digital signal for transmission
Encoding
One bit per second
One BPs
