IEE 802.3 користи на MAC подслоју протокол?
- A.
CSMA/CD
- B.
Token ring
- C.
Token pass
- D.
CSMA/CA
Correct Answer
A. CSMA/CDExplanation
The correct answer is CSMA/CD. IEE 802.3, also known as Ethernet, uses the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol at the MAC sublayer. This protocol allows multiple devices to access the network at the same time by listening for carrier signals and checking for collisions. If a collision is detected, the devices involved wait for a random amount of time before retransmitting their data. CSMA/CD is commonly used in Ethernet networks to ensure efficient and reliable communication.Rate this question:

Који протокол се користи у бежичним локалним мрежама
- A.
CSMA/CD
- B.
CSMA/CA
- C.

Correct Answer
B. CSMA/CAExplanation
CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) is the correct answer. CSMA/CA is a protocol used in wireless local area networks (WLANs) to avoid collisions between data packets. It works by requiring devices to listen for a clear channel before transmitting data, and if the channel is busy, the device waits for a random period of time before attempting to transmit again. This helps to minimize collisions and improve the overall efficiency of the network.Rate this question:

- C.
Слања, сукобљавања и неактивни периоди
- D.
сукубљавања и неактивни периоди
Correct Answer
C. Слања, сукобљавања и неактивни периодиExplanation
The correct answer is "Слања, сукобљавања и неактивни периоди" which translates to "Transmissions, collisions, and idle periods." In the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol, stations on a shared network listen for any ongoing transmissions before attempting to transmit data. If multiple stations try to transmit at the same time, a collision occurs and all stations involved detect the collision. After a collision, there is a random backoff time or an idle period before the stations attempt to retransmit the data. Therefore, the correct answer includes all three components of the CSMA/CD protocol.Rate this question:

- A.
ALOHA
- B.
CSMA
- C.
TDM
- D.
FDM
Correct Answer
B. CSMAExplanation
The correct answer is CSMA (Carrier Sense Multiple Access). CSMA is a method used to access a transmission medium in a network. When a station wants to send data, it first checks if any other station is already using the transmission medium. If the medium is idle, the station can start transmitting. If the medium is busy, the station waits for it to become idle before transmitting. This method helps to avoid collisions and ensures efficient use of the transmission medium.Rate this question:

Sloju veze
Correct Answer
C. Transportnom slojuExplanation
The correct answer is "Transportnom sloju" (Transport layer). The transport layer is responsible for the end-to-end delivery of data between the source and destination devices. It ensures that the data is delivered reliably and efficiently by providing services such as segmentation, flow control, and error recovery. This layer establishes connections, manages data transfer, and handles any issues that may arise during transmission.Rate this question:

Correct Answer
C. 7 slojevaExplanation
The correct answer is 7 slojeva. The OSI model refers to the Open Systems Interconnection model, which is a conceptual framework that standardizes the functions of a communication system into seven different layers. These layers, from bottom to top, are: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Each layer has specific responsibilities and interacts with the layers above and below it to ensure effective communication between network devices.Rate this question:

Koji je prvi sloj u OSI referentnom modelu
- A.
Aplikacioni
- B.
Mrezni
- C.
Fizicki
- D.
Transportni
Correct Answer
C. FizickiExplanation
The correct answer is "Fizicki" (Physical). In the OSI reference model, the physical layer is the first layer. It is responsible for the actual transmission and reception of raw bit streams over a physical medium. This layer deals with the physical characteristics of the transmission medium, such as voltage levels, electrical and mechanical specifications, and the physical connectors. It ensures that the data is transmitted reliably and accurately from one device to another.Rate this question:

Kod OSI referentnog modela, ukoliko dodje do promene na jednom sloju
- A.
Promena utice na sve slojeve
- B.
Promena utice samo na susedne slojeve
- C.
Promena ne utice na ostale slojeve
- D.
Po standardu, nije dozvoljeno unositi promene u slojevima
Correct Answer
C. Promena ne utice na ostale slojeveExplanation
In the OSI reference model, if there is a change in one layer, it does not affect the other layers. Each layer in the OSI model is designed to operate independently and provide specific functionalities. This separation allows for easier troubleshooting, maintenance, and upgrades without impacting the entire network stack. Therefore, any change in one layer will not have a direct impact on the other layers in the OSI model.Rate this question:

Aplikacioni sloj omogucava aplikacionom procesu da pristupi OSI okruzenju
Correct Answer
D. Aplikacioni sloj omogucava aplikacionom procesu da pristupi OSI okruzenjuExplanation
The correct answer states that the application layer allows the application process to access the OSI environment. This means that the application layer provides the necessary protocols and services for the application process to communicate with other processes in the network. It is responsible for managing the application-level communication and ensuring that the data is properly formatted and delivered to the appropriate destination.Rate this question:

Fizicki sloj i sloj veze
- B.
Sloj veze i mrezni sloj
- C.
Transportni sloj i slojevi iznad njega
- D.
Mrezni i transportni sloj
Correct Answer
C. Transportni sloj i slojevi iznad njegaExplanation
The correct answer is "Transportni sloj i slojevi iznad njega" (Transport layer and the layers above it). This answer is correct because the OSI reference model consists of seven layers, and the transport layer is the fourth layer. The layers above the transport layer include the session layer, presentation layer, and application layer. These layers are responsible for managing the end-to-end communication between applications and ensuring the reliable delivery of data.Rate this question:
