Module 1 Flashcards
A basic unit of information that represents one of two discrete states is known as a?
Bit.
Bit is an abbreviation for “binary digit”.
How is bandwidth usually measured (the unit of measurement)?
Bits
The number of bits that (theoretically) can be sent across the media in a second. Bandwidth is typically measured in thousands of bits per second (Kbps), millions of bits per second (Mbps) and billions of bits per second (Gbps).
The capacity of the medium to carry data is known as?
Bandwidth.
Digital bandwidth measures the the amount of data that can flow from one place to another in a given amount of time.
No answer, just a statement 😄
What is a peer-to-peer network?
A network that consists of two directly connected computers where both computers are able to exchange data and services with each other, and each device is both a client and a server.
What is bandwidth?
The capacity of a medium to carry data.
Latency is the amount of time, including delays, for data to travel from one given point to another.
No answer, just a statement 💻
Throughput measures the transfer of bits across the media over a given period of time.
BONUS! Throughput does not usually match the specified bandwidth.
What port does an RJ-11 connector plug in to?
DSL - an RJ-11 is a telephone-type jack, only capable of transmitting analog data from things like landline phones and fax.
Which measurement includes any latency encountered during data transmissions?
Throughput.
Which method of signal transmission do optical signals use?
frequencies or pulses of light.
Why are coaxial cables so heavily insulated?
To prevent signal leakage or repel external electromagnetic waves. And when these cables are used underground, the outside metal layer transmits any disturbing signals/static electricity into the ground.
Ethernet hubs have mostly been replaced by switches. What is the term used to describe hubs now?
Obsolete.
What are coaxial cables used for?
Cable TV, high-speed internet, telecommunications - provides super-high speeds and can carry large amounts of data required for these transmissions.
What is STP’s main feature?
High-speed data transfer.
