FTP stands for File Transfer Protocol. It is a standard network protocol used for the transfer of computer files between a client and server on a computer network.
1072
Block coding at the receiver helps with:
Answer:
Both A and B
Block coding adds redundancy to data which can be used by the receiver to help maintain clock synchronization and detect transmission errors.
1073
Which error detection method adds only one redundant bit to each data unit?
Answer:
Simple parity check
A simple parity check involves adding a single bit to make the total number of 1s in the data unit either even or odd.
1074
In IEEE 802.11, communication between two stations in different BSSs usually occurs via:
Answer:
APs
Access Points (APs) are used to connect different Basic Service Sets (BSSs) into a larger Extended Service Set (ESS).
1075
Bit stuffing is the process of adding an extra 0 in the data part of the frame when a bit sequence matches the:
Answer:
Flag
In protocols like HDLC, bit stuffing is used to ensure that the flag sequence (01111110) does not accidentally appear within the data payload.
1076
The chief difference between DDCMP and SDLC is:
Answer:
DDCMP needs no special hardware to mark start of message
DDCMP messages are self-delimiting, while SDLC requires flag sequences
1077
In IEEE 802.11, a network of wireless stations with an optional central AP is called a:
Answer:
BSS
A Basic Service Set (BSS) is the fundamental building block of an 802.11 wireless LAN.
1078
Which defines how messages are formatted and transmitted, and what actions web servers and browsers should take in response to various commands?
Answer:
HTTP
HTTP, the Hypertext Transfer Protocol, is the foundation of data communication for the World Wide Web. It is a protocol that defines the format of requests and responses between web clients (browsers) and web servers, dictating how they communicate.
1079
Which error detection technique uses one’s complement arithmetic?
Answer:
Checksum
The Internet Checksum algorithm uses one's complement addition to calculate a value for error detection in data packets.
1080
In TCP/IP, which layer combines session, presentation, and application layers of OSI?
Answer:
Application
The application layer in the TCP/IP model handles the functions of the OSI model's application, presentation, and session layers.
