Lesson 5

Question 1

Means transferring data between two devices

Answer 1

Transmission mode

Question 2

Transmission mode is also known as

Answer 2

Communication mode

Question 3

Transmission is possible in both directions at the same time but not between the same two stations

Answer 3

Full/Full Duplex Mode

Question 4

Only one of the two devices on a link can transmit, the other can only receive.

Answer 4

Simplex Mode

Question 5

Are designed to allow communication to occur between individual devices that are interconnected

Answer 5

Buses and networks

Question 6

Types of Transmission Mode

Answer 6

Simple Mode, Half Duplex Mode, Full Duplex Mode

Question 7

The communication is unidirectional, as on a one-way street

Answer 7

Simplex Mode

Question 8

Each station can both transmit and receive but not at the same time.

Answer 8

Half-Duplex Mode

Question 9

Both stations can transmit and receive simultaneously

Answer 9

Full-Duplex Mode

Question 10

Used in cases where there is no need for communication in both directions at the same time.

Answer 10

Half-Duplex Mode

Question 11

The entire capacity of the channel can be utilized for each direction.

Answer 11

Half-Duplex Mode

Question 12

Signals going in one direction share the capacity of the link with signals going in other direction

Answer 12

Full-Duplex Mode

Question 13

In full-duplex mode, sharing can occur in two ways

Answer 13

1. Either the link must contain two physically separate transmission paths, one for sending and other for receiving

2.Or the capacity is divided between signals traveling in both directions. Full duplex mode is used when communication in both direction is required all the time.

Question 14

Possible only on multipoint circuit

Answer 14

Full/full duplex

Question 15
