Racunarske Mreze Test 1 I 2

The correct answer is "Пакета" because the term "пакета" refers to packet switching, which is a method of transmitting data in which messages are divided into small packets and sent separately over the network. This method allows for more efficient use of network resources and better handling of network congestion compared to other methods such as circuit switching.

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.

A радна станица треба да има мрежни адаптер да би се повезала на мрежу. Мрежни адаптер је хардверски уређај који омогућава радној станици да комуницира са мрежом. Он прима и шаље податке преко мрежног кабла и претвара их у облик који се може пренети преко мреже. Без мрежног адаптера, радна станица не би била у могућности да се повеже на мрежу и комуницира са другим уређајима на мрежи.

A typical channel-switching network refers to a telephone network, where calls are routed through different channels to establish connections between callers. This network allows users to make voice calls over long distances using the telephone system.

A local network is a communication network that connects devices within a building or a block of buildings. This means that the correct answer is "У згради или блоку зграда" which translates to "In a building or a block of buildings".

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.

TCP/IP is the set of communication protocols used on the internet. It stands for Transmission Control Protocol/Internet Protocol and is responsible for establishing and maintaining network connections, as well as routing data packets across networks. TCP/IP is the foundation of the internet and allows different devices and networks to communicate with each other. WINS, HTTP, and FTP are also communication protocols, but they are not specifically used on the internet like TCP/IP.

The correct answer is "Мреже са комутацијом канала, порука, пакета" which translates to "Networks with channel switching, message switching, and packet switching". This answer is correct because it accurately describes the types of networks that involve switching at the channel, message, and packet levels. These types of networks are commonly used in telecommunications and data networks to efficiently transfer data between multiple nodes.

A public telephone network is an example of a network with channel switching because it uses circuit-switching technology to establish a dedicated communication path between two parties during a phone call. This means that a dedicated channel is allocated for the duration of the call, ensuring a reliable and secure connection. In contrast, networks like MAN, LAN, and the Internet use packet-switching technology, where data is divided into packets and sent over shared channels.

SAP stands for Service Access Point. It is used to designate the point at which a service can be accessed in a network. In the context of the question, SAP is the correct answer because it is the term used to indicate how service access points are designated in networking. PDU stands for Protocol Data Unit, which refers to the unit of data that is transmitted over a network. SDU stands for Service Data Unit, which is the data unit that is passed between a service user and a service provider. NAP stands for Network Access Point, which is a physical location where different networks can connect to exchange traffic.

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.

In a broadcast network, all devices are connected to a single communication channel, known as a bus or backbone. This type of network is called a "магистрала" or "bus" network. In a bus network, all devices receive the same message simultaneously, and any device can transmit data onto the bus for all other devices to receive.

The main characteristic of the technique of accessing with virtual circuits is that establishing a route before data transmission is mandatory.

The correct answer is "Захтев, идентификација, одговор, потврда" which translates to "Request, identification, response, confirmation". This set represents the primitives of service. When a client sends a request to a server, it needs to identify itself, and the server responds with a response message. The confirmation is then sent by the server to acknowledge the successful completion of the request.

The correct answer is 3 phases. In a channel switching system, there are typically three phases of communication establishment. These phases include the setup phase, where the connection is initiated and parameters are negotiated, the data transfer phase, where the actual communication takes place, and the teardown phase, where the connection is terminated and resources are released. These phases ensure a smooth and organized communication process within the system.

The correct answer states that there are different types of communication networks based on the switching method used, which includes channel switching, message switching, and packet switching. This means that communication networks can be classified based on how they handle the transmission of data, whether it is by dedicating a channel for the entire duration of the communication, sending the entire message at once, or breaking the message into smaller packets for transmission.

A "свако са сваким" network refers to a network where every node is directly connected to every other node. A radio network can be an example of this type of network, as each device in the network can communicate with every other device using radio waves. In a client-server network, USB connection, or satellite transmission, the communication is not directly between every node, so they are not examples of a "свако са сваким" network.

The correct answer is "Странице, чворови, традициони медијуми" which translates to "Pages, nodes, traditional media" in English. This answer suggests that communication networks consist of various components such as web pages, nodes (which are devices or points in the network), and traditional media. These components play a role in facilitating communication within the network.

The given answer "Интерпретирају" is the correct answer because it means "interpret" in English. The question is asking about the process of information creation, and the other options (converting from analog to digital, transmitting, and formatting for communication) are steps that may be involved in the process, but the final step is the interpretation of the data to make sense of it and derive meaning from it.

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.

If a node is out of function in a network with virtual circuits, the connection is reestablished. This means that the node will try to reconnect and resume communication with the network.

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.
