A.
Multiplexers are designed to accept data from several I/O devices and transmit a unified stream of data on one communication line. |
|
B.
HDLC is a standard synchronous communication protocol. |
|
C.
RTS/CTS is the way the DTE indicates that it is ready to transmit data and the way the DCE indicates that it is ready to accept data. |
|
D.
RTS/CTS is the way the terminal indicates ringing |
|
E.
None of the above |
|
A.
Token-Ring because it currently can run at both 4Mbps and 16Mbps. This means that it can be used in any topology |
|
B.
Ethernet, because it is cabled using fiber-optic cable |
|
C.
Token-Ring, because it uses a MAU |
|
D.
Ethernet, because it can be set up with most topologies and can use multiple transfer speeds |
|
E.
Neither Token-Ring nor Ethernet is the proper choice. Only ARCnet can be used in all topologies |
