The Simplest Protocol and Stop-and-Wait Protocol are designed for \_\_ channels.
Answer:
Either B or C
These basic protocols operate under the ideal assumption of a noiseless, error-free channel where data frames are never lost or corrupted.
1062
Which communication protocol is the primary method used by the internet for data exchange?
Answer:
TCP/IP
TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, is the foundational suite of communication protocols used to interconnect network devices on the internet. It provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received.
1063
In Go-Back-N ARQ, if frames 4, 5, and 6 are received successfully, the receiver may send an ACK numbered:
Answer:
7
In Go-Back-N, the acknowledgment number indicates the sequence number of the next frame the receiver expects to receive.
1064
In Bluetooth, which layer corresponds to the MAC sublayer in LANs?
Answer:
Baseband
The Baseband layer in Bluetooth manages physical channels and links, performing functions similar to the MAC sublayer.
1065
In Go-Back-N ARQ with a window size of 63, the sequence number range is:
Answer:
0 to 63
With a window size of N, the sequence numbers typically range from 0 to N-1.
1066
Software-based monitors for data communications include:
Answer:
Telnet
Telnet is a software tool for monitoring and managing data communications.
1067
TCP/IP is a \_\_-layer hierarchical protocol suite developed \_\_ the OSI model.
Answer:
Five-layer; before
The TCP/IP model is typically described with four or five layers and its development predates the formal seven-layer OSI model.
1068
IEEE’s wireless LAN standard covering physical and data link layers is:
Answer:
IEEE 802.11
The IEEE 802.11 family of standards defines the protocols for wireless local area networks (Wi-Fi).
1069
Select the incorrect statement.
Answer:
RTS/CTS is used to signal ringing status at the terminal.
RTS/CTS is for data transmission readiness, not for indicating ringing.
1070
In CSMA/CA, RTS and CTS frames \_\_ solve the hidden station problem and \_\_ solve the exposed station problem.
Answer:
Can; cannot
Request to Send (RTS) and Clear to Send (CTS) frames reserve the medium to prevent collisions from hidden stations, but they do not solve the exposed station problem.
