Voor CCNA  Datacom geen onderscheidt nodig.

OSI model beschrijft op Data Link niveau&nbsp;<div>&nbsp; - Welk signaal wordt gemaakt voor het medium</div><div>&nbsp; - Wanneer iemand mag zenden&nbsp;</div><div>-Welk MACadres wordt gebruikt&nbsp; voor aflevering data in EIGEN netwerk</div><div><br></div><div><br></div>

Segment

Packet

Frame

Data

What is done to an IP packet before it is transmitted over the physical medium?

1. It is encapsulates in a Layer 2 frame
2. It is segmented into smaller individual pieces
3. It is encapsulated into a TCP segment
4. It is tagged with information guaranteeing reliable delivery

In computer communication, what is the purpose of message encoding?

1. to break large messages into smaller frames
2. to interpret information
3. to convert information to the appropriat form for transmission
4. to negoriate correct timing for successful communication

What is the purpose of protocols in data communications?

1. dictating the content of the message sent during communication
2. specify the device operating systems that will support the communication
3. specify the bandwidth of the channel or medium for eachtype of communication
4. providing the rules required for a specific type of communication to occur
