1 Communication in Connected World Flashcards
(27 cards)
allows computers in a home office or a remote office to connect to a corporate network, or access centralized, shared resources
SOHO
This is created and explicitly shared by individuals, such as social network profiles. This type of data might include video files, pictures, text, or audio files.
Volunteered Data
This is captured by recording the actions of individuals, such as location data when using cell phones.
Observed Data
This is data such as a credit score, which is based on analysis of volunteered or observed data.
Inferred Data
an abbreviation of “binary digit” and represents the smallest piece of data. Each bit can only have one of two possible values, 0 or 1.
Bit
Transmission is achieved by representing data as electrical pulses on copper wire.
Electric Signals
Transmission is achieved by converting the electrical signals into light pulses.
Optical Signals
Transmission is achieved by using infrared, microwave, or radio waves through the air.
Wireless Signals
capacity of a medium to carry data.
Bandwidth
measures the amount of data that can flow from one place to another in a given amount of time.
Digital Bandwidth
typically measured in the number of bits that (theoretically) can be sent across the media in a second.
Bandwidth
Bandwidth Thousands of bits per second
Kbps
Bandwidth Millions of bits per second
Mbps
Bandwidth Billions of bits per second
Gbps
Throughput does not usually match
the specified bandwidth
Due to
The amount of data being sent and received over the connection
The latency created by the number of network devices encountered between source and destination
refers to the amount of time, including delays, for data to travel from one given point to another.
Latency
the type of physical media used by computers to access the World Wide Web
