- C.
Vreme konvergencije
Correct Answer
C. Vreme konvergencijeExplanation
Vreme potrebno za usklađivanje informacija između svih rutera u mreži naziva se vreme konvergencije. Ovo je vreme koje je potrebno da se svi ruteri u mreži usklade sa ažuriranim informacijama o mreži, kao što su promene u topologiji ili rutiranju. Vreme konvergencije je važno jer utiče na stabilnost i performanse mreže, jer što je kraće vreme konvergencije, to će mreža brže reagovati na promene i preusmeriti saobraćaj na optimalan put.Rate this question:

Podrazumevani transportni protokol koga koristi SMTP protokol je:
- A.
UDP
- B.
HTTP
- C.
POP3
- D.
IMAP
- E.
TCP
Correct Answer
E. TCPExplanation
SMTP (Simple Mail Transfer Protocol) is a protocol used for sending email messages between servers. The default transport protocol used by SMTP is TCP (Transmission Control Protocol). TCP ensures reliable and ordered delivery of data packets, making it suitable for transmitting email messages. UDP (User Datagram Protocol) is a connectionless protocol that does not guarantee reliable delivery, making it unsuitable for SMTP. HTTP (Hypertext Transfer Protocol) is used for web communication, while POP3 (Post Office Protocol version 3) and IMAP (Internet Message Access Protocol) are used for email retrieval, not for the transport of email messages.Rate this question:

- C.
1960. godine
- D.
1991. godine
Correct Answer
D. 1991. godineExplanation
The correct answer is 1991. godine. This is because the World Wide Web (WWW), which is a system of interlinked hypertext documents accessed through the internet, was invented by Tim Berners-Lee in 1989 and became publicly available in 1991. Therefore, the development of web services on the internet can be attributed to this time period.Rate this question:

Jedan od tipova jednosmerne asinhrone video—konferencije putem Internet mreze naziva se:
- A.
Broadcasting
- B.
Internet telefonija
- C.
Webcasting
Correct Answer
C. WebcastingExplanation
Webcasting is a type of one-way asynchronous video conference conducted over the internet. It involves the broadcasting of audio and video content to a large audience, allowing them to view the conference remotely. Unlike internet telephony, which involves two-way communication, webcasting is primarily focused on delivering content to viewers rather than facilitating interactive communication. Broadcasting refers to the transmission of audio or video signals to a large number of recipients simultaneously, but it does not specifically refer to video conferences conducted over the internet. Therefore, the correct answer is webcasting.Rate this question:

Bitska duzina zaglavlja segmenata TCP protokola je:
- A.
Promenljiva
- B.
Fiksna (32 bita)
- C.
Fiksna (160 bitova)
Correct Answer
A. PromenljivaExplanation
The correct answer is "promenljiva." The header length of TCP segments can vary depending on the options and extensions being used. Unlike the other options that specify a fixed length (32 bits or 160 bits), a variable header length allows for flexibility and adaptability in the TCP protocol.Rate this question:

Klase mreznih adresa su zamenljive besklasnim adresovanjem:
- A.
2001. godine
- B.
1993. godine
- C.
2011. godine
- D.
1981. godine
Correct Answer
B. 1993. godineExplanation
In 1993, the Internet Engineering Task Force (IETF) introduced the Classless Inter-Domain Routing (CIDR) system, which replaced the traditional classful addressing system. CIDR allowed for more efficient allocation of IP addresses by allowing networks to be divided into smaller subnets. This eliminated the need for strict class boundaries and made the addressing system more flexible. Therefore, the statement "Klase mreznih adresa su zamenljive besklasnim adresovanjem" means that network classes were replaced by classless addressing in 1993.Rate this question:
