Networking 3 Flashcards
- delivers the packets
- allows the devices to really see their place
IP
Message sources are people, or electronic devices, that need to send a message to other individuals or devices.
Message source (sender)
The destination receives the message and interprets it.
Message Destination (receiver)
This consists of the media that provides the pathway over which the message travels from source to destination.
Channel
Common computer protocols include the following requirements
- message encoding
- message formatting and encapsulation
- message size
- message timing
- message delivery option
is the process of converting information into another acceptable form, for transmission
encoding
reverses this process to interpret the information.
decoding
When a message is sent from source to destination, it must use a specific format or structure. Message formats depend on the type of message and the channel that is used to deliver the message.
Message Formatting and Encapsulation
The size restrictions of frames require the source host to break a long message into individual pieces that meet both the minimum and maximum size requirements. The long message will be sent in separate frames, with each frame containing a piece of the original message.
Message Size
The size restrictions of frames require the source host to break a long message into individual pieces that meet both the minimum and maximum size requirements. The long message will be sent in separate frames, with each frame containing a piece of the original message.
Message Size
This is the process of managing the rate of data transmission. Flow control defines how much information can be sent and the speed at which it can be delivered.
Flow Control
If a person asks a question and does not hear a response within an acceptable amount of time, the person assumes that no answer is coming and reacts accordingly.
Response Timeout
This determines when someone can send a message
Access method
Information is being transmitted to a single end device.
Uncast
Information is being transmitted to a multiple end device.
Multicast
Information is being transmitted to all end device.
Broadcast
This identifies the sender and the intended receiver of the message using a defined addressing scheme
