    Kod OSI referentnog modela, ukoliko dodje do promene na jednom sloju

    • Promena utice na sve slojeve

    • Promena utice samo na susedne slojeve

    • Promena ne utice na ostale slojeve

    • Po standardu, nije dozvoljeno unositi promene u slojevima

    Correct Answer
    A. Promena ne utice na ostale slojeve
    Explanation
    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.

    Код ког метода за приступ трансмисионом медијуму примењен је следећи принцип:Када станица жели да шаље податке она прво проверава да ли је нека друга станица већ заузела трансмисиони медијум?

    • ALOHA

    • CSMA

    • TDM

    • FDM

    Correct Answer
    A. CSMA
    Explanation
    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.

    Који сигнал бежична станица користи да би иницирала комуникацију са другом бежичном станицом са циљем да заобиђе проблем скривеног терминала

    • CTS

    • RTS

    • EOF

    • Option 4

    Correct Answer
    A. RTS
    Explanation
    RTS stands for Request to Send. In wireless communication, RTS is used by a wireless station to initiate communication with another wireless station in order to avoid the hidden terminal problem. The hidden terminal problem occurs when two wireless stations are within range of a third station, but not within range of each other. By sending an RTS signal, the station is requesting permission to transmit data and informing other stations to wait until the transmission is complete. This helps to prevent collisions and ensures that the communication is successful.

    Који сигнал бежична станица користи да би потврдила да хоће да комуницира са другом бежичном станицом?

    • RTS

    • CTS

    • EOF

    • Miodrag signal

    Correct Answer
    A. CTS
    Explanation
    CTS stands for Clear to Send. It is a signal used by a wireless station to confirm that it is ready to communicate with another wireless station. This signal is typically sent by the receiving station after it has successfully received a Request to Send (RTS) signal from the transmitting station. The CTS signal helps to avoid collisions and manage the communication between wireless devices in a network.

    Na slici je prikazano - ProProfs

    Na slici je prikazano

    • Infrastuktura

    • Mreza samo za ovu priliku

    • Isprepletana mreza

    • Celijska

    Correct Answer
    A. Isprepletana mreza
    Explanation
    The correct answer is "Isprepletana mreza" because the given text mentions "na slici je prikazano" which translates to "the picture shows." Therefore, it can be inferred that the image represents a network, and "Isprepletana mreza" means "interwoven network" in English, which could be a suitable description for the image.

    Време рањавања једнако је

    • Четвороструком времену пропагације између две најудаљеније станице

    • Минималном времену пропагације између две најудаљеније станице

    • Двостурком времену пропагације између две најудаљеније станице

    • Максималном времену пропагације(простирања) између најудаљенијих станица

    Correct Answer
    A. Максималном времену пропагације(простирања) између најудаљенијих станица
    Explanation
    The correct answer is "Максималном времену пропагације(простирања) између најудаљенијих станица". This means that the time of propagation (spread) between the furthest pages is the maximum. This suggests that the time it takes for information to travel between the most distant pages is the longest, resulting in a longer time for the system to recover from a fault or failure.

    • Sa uspostavom veze

    • Bez uspostave veze

    • Svako sa svakim

    • Zavisi od nacina konfirguracije, moze biti i sa i bez uspostave veze

    Correct Answer
    A. Sa uspostavom veze
    Explanation
    The correct answer is "sa uspostavom veze" because TCP (Transmission Control Protocol) is a connection-oriented protocol. It establishes a reliable and secure connection between the sender and receiver before data transmission. This connection ensures that data packets are delivered in the correct order and without errors.

    IEE 802.3 користи на MAC подслоју протокол?

    • CSMA/CD

    • Token ring

    • Token pass

    • CSMA/CA

    Correct Answer
    A. CSMA/CD
    Explanation
    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.

    Correct Answer
    A. повезују на заједнички трансмисиони медијум
    Explanation
    The correct answer is "повезују на заједнички трансмисиони медијум" which means "are connected to a shared transmission medium". This means that the physical topology of the network connects all the stations to a common transmission medium, which allows for communication between the stations.
