Bits, Bytes and Ethernet Frames Flashcards
Data is binary. What does that mean?
Composed of two things, and in this case: An on or an off.
How do computers technically communicate with one another?
Data is sent across a wire between two PCs in the form of 1’s and 0’s, ons and off (either there is an electrical pulse or there isn’t.)
What is data measured in?
bits.
How many bits are in a single Byte?
Eight.
How are network data rates measured?
bits per second (bps). Ex. Kbps, Mbps, Gbps, Tbps
How many bits are 1000 Bytes?
8000 bits
How are file sizes measured?
Bytes.
How many ons and offs we can create in one second is described as what?
Data rate.
What is a packet switch network?
A network that has been created where the information sent on the wire is in small chunks.
What are the benefits of a packet switched network?
The network is more manageable, can do more with it, could route it, utliize more of the bandwidth on a specific connection and get more out of the wire.
How big is a frame payload?
1500 Bytes in size.
What does a frame consist of at a high level?
A payload and addressing information.
What is ethernet?
A protocol family of standard that supports many types of media and data rates.
What is the Ethernet Standard?
IEEE standard 802.3
What performs encapsulation of frames?
The ethernet protocol.
Where do frames begin and end?
The NIC, Network Interface Card.
How do network devices send and receive data?
In chucks called frames.
