ITPEC IP April 2022 — Question 30 of 100
NTP synchronizes a computer's internal clock with a reference time server over a network. Network Time Protocol exchanges time information and estimates network delay so clients can adjust their clocks. Accurate shared time is important for logs, authentication, distributed processing, and scheduled operations.
Answer (b)
Why not others:
- FTP transfers files
- POP retrieves e-mail from a mail server
- SMTP sends and relays e-mail
Key rule: NTP is the network clock-synchronization protocol; FTP, POP, and SMTP serve file-transfer or e-mail functions.
