    Provera parnosti, kao tehnika za otkrivanje gresaka tokom prenosa podataka, ima mogucnost da oktrije sledeci procenat gresaka:

    • Procenat varira u zavisnosti od kvaliteta veze

    • 99,9%

    • 25%

    • 100%

    • 75%

    • 50%

    Correct Answer
    A. 50%
    Explanation
    The given question asks about the percentage of errors that can be detected using the parity checking technique for data transmission. Parity checking is a simple technique that adds an extra bit to the data being transmitted to check for errors. In this technique, if the number of 1s in the data is even, the parity bit is set to 0, and if the number of 1s is odd, the parity bit is set to 1. Therefore, the parity checking technique can only detect errors when an odd number of bits are flipped during transmission. Since the given question does not provide any information about the quality of the connection, we can assume an equal probability of bit errors, resulting in a 50% chance of detecting errors using parity checking.

    • 1981. Godine

    • 1993. Godine

    • 2011. Godine

    • 2001. Godine

    Correct Answer
    A. 1993. Godine
    Explanation
    In 1993, the classful addressing system was replaced with classless addressing. Classful addressing divided IP addresses into classes (A, B, C, D, and E) based on the number of network and host bits. This system was inefficient as it allocated large blocks of addresses to organizations, resulting in address wastage. Classless addressing, on the other hand, allows for more flexible allocation of IP addresses by using variable-length subnet masks. This change in addressing was necessary to accommodate the growing demand for IP addresses and to make more efficient use of the available address space.

    Racunar salje podatke preko iznajmljene linije. U pitanju je:

    • Geocast

    • Point-to-point

    • Broadcast

    • Anycast

    • Multicast

    Correct Answer
    A. Point-to-point
    Explanation
    The correct answer is "Point-to-point". In this scenario, the computer is sending data over a leased line, which means it is establishing a direct connection between two specific points. This is different from broadcast, where data is sent to all devices on a network, or multicast, where data is sent to a select group of devices. Anycast and geocast are not relevant in this context.

    Ukoliko je potrebno povezati dva racunara putem PSTN mreze, tako da se izbegne kasnjenje vezano za biranje broja, potrebno je koristiti:

    • VoIP

    • Dial-up

    • Iznajmljenu liniju

    • VPN

    Correct Answer
    A. Iznajmljenu liniju
    Explanation
    When connecting two computers via the PSTN network, using a leased line is necessary to avoid any delays associated with dialing a number. A leased line provides a dedicated, always-on connection between the two computers, ensuring a stable and reliable connection without the need for dialing. VoIP, Dial-up, and VPN are not suitable options for avoiding dialing delays in this scenario.

    Ukoliko nakon podizanja operativnog sistema racunara njegov mrezni interfejs ima adresu iz opsega 169.254.0.0/16 to obicno ukazuje na:

    • DHCP kao izvor zadate adrese

    • DNS kao izvor zadate adrese

    • Probleme u radu servisa adresovanja

    • Staticku zadatu adresu

    Correct Answer
    A. Probleme u radu servisa adresovanja
    Explanation
    The correct answer is "Probleme u radu servisa adresovanja" because when a computer's network interface has an address in the range of 169.254.0.0/16, it usually indicates that there are issues with the address assignment service. This range is reserved for Automatic Private IP Addressing (APIPA), which is used when a device is unable to obtain an IP address from a DHCP server. Therefore, it suggests that there may be problems with the DHCP service or network configuration.

    Internet protokol funksionise:

    • Sa uspostavljanjem I bez raskida veze

    • Sa uspostavljanjem I raskidom veze

    • Bez uspostavljanja I raskida veze

    Correct Answer
    A. Bez uspostavljanja I raskida veze
    Explanation
    Internet protocol functions without establishing and terminating a connection. This means that data can be transmitted over the internet without the need for a formal connection setup or termination process. This is achieved through the use of packet switching, where data is divided into small packets and sent individually across the network. Each packet is then independently routed to its destination, allowing for efficient and flexible communication without the need for a continuous connection.

    Komunikacija izmedju racunara koji koriste gigabitni Eternet je sledeceg tipa:

    • Simpleks

    • Polu-dupleks

    • Sa mogucim kolizijama

    • Puni-dupleks

    • Multicast

    Correct Answer
    A. Puni-dupleks
    Explanation
    The communication between computers using gigabit Ethernet is full-duplex, meaning that data can be transmitted and received simultaneously. In full-duplex mode, there is a dedicated channel for each direction of communication, allowing for faster and more efficient data transfer. This eliminates the possibility of collisions, as opposed to half-duplex or simplex modes where collisions can occur. Multicast refers to the transmission of data to multiple recipients simultaneously and is not specific to the type of communication between computers using gigabit Ethernet.
