Correct Answer
A. Виртуелно коло и датаграмExplanation
The correct answer is "Виртуелно коло и датаграм" which translates to "Virtual circuit and datagram" in English. This answer suggests that packet switching can be done using both virtual circuits and datagrams. Virtual circuit switching involves establishing a dedicated communication path between the sender and receiver before transmitting data, while datagram switching involves sending individual packets independently without any pre-established path. Both methods are commonly used in packet-switched networks.Rate this question:

-
Потпуни дуплекс
-
Не постоји могућност слања података у оба правца истовремено
Correct Answer
A. Потпуни дуплексExplanation
The correct answer is "Потпуни дуплекс" because it refers to the ability to transmit data in both directions simultaneously. In full duplex communication, data can be sent and received at the same time, allowing for faster and more efficient communication. This is different from half duplex, where data can only be sent or received at a time, and simplex, where data can only be sent in one direction.Rate this question:

Correct Answer
A. Базирају се на комутацији пакетаExplanation
Contemporary communication systems are based on packet switching. This means that data is divided into small packets and sent over a network. Each packet is then independently routed to its destination, allowing for more efficient use of network resources and faster data transmission. Packet switching also enables the transmission of different types of data, such as voice, video, and text, simultaneously over the same network. This method of communication has become the foundation for modern telecommunications systems.Rate this question:

Канал је унапред подељен на подканале, и станицама се додељује одређени фрекфенцијски опсег
Correct Answer
A. За све време трајања везе заузет је канал између две станицеExplanation
The main characteristic of channel switching is that the channel is occupied between two stations for the entire duration of the connection. This means that once a connection is established, the channel is exclusively used by the two stations involved in the communication. Unlike other forms of switching, such as circuit switching or packet switching, where the channel may be shared or divided among multiple stations, channel switching ensures that the channel remains dedicated to the two communicating stations for the entire duration of the connection.Rate this question:

When a node is out of function in a datagram network, the packets are redirected to another functional node for further processing. This is because in a datagram network, each packet is treated independently and can be routed individually. Therefore, when a node is not functioning, the packets can be rerouted to ensure their delivery.Rate this question:
