Test: Data Link Layer & MAC-Sublayer- 1

The hamming distance is the minimum number of positions where any two legal code words differ by bit.
Hamming distance between 001111 and 010011 is 3.

Pincode is not related to ethernet message packet.

The frequency range of coaxial cable

Packet-switching network reduce cost using an inform ation utility and allow communication channels to be shared among more than one user.

Local area network can transmit faster than telecommunications over public telephone lines because they uses twisted pair wiring or coaxial cable, which has faster data transmission rate

We have 2, 4, 6 device T-switches. It we use 4 device T-switch then T-switch used to manage a shared resource between 4 devices.

Fiber distributed data interface (FDDI) is a local area network. It supports data rates of 100 Mbps and provides a high speed alternative to Ethernet and Token Ring. It is a ring network

Circuit switching involves connection establishment data transfer and connection release as three phases in communication.

Error detection at data link layer is achieved by CRC.

Network layer provides host-to-host connectivity. Hop-to-hop connectivity is provided by data Sink layer. Transport layer provides end to end (process-to-process) connectivity.
