The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware.
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
The ntpd program is an operating-system daemon that sets and maintains a computer system's system time in synchronization with Internet-standard time servers.It is a complete implementation of the Network Time Protocol (NTP) version 4, but retains compatibility with versions 1, 2, and 3 as defined by RFC 1059, RFC 1119, and RFC 1305, respectively. ntpd performs most computations in 64-bit ...
An ephemeral port is a communications endpoint of a transport layer protocol of the Internet protocol suite that is used for only a short period of time for the duration of a communication session. Such short-lived ports are allocated automatically within a predefined range of port numbers by the IP stack software of a computer operating system.

A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
Unlike POP3, your messages aren't downloaded to your computer or device, thus you can sync your account on multiple platforms. If you switch from POP3 to IMAP, only new messages will move from the server to your devices.
OpenNTPD is an attempt by the OpenBSD team to produce an NTP daemon implementation that is secure, simple to audit, trivial to set up and administer, reasonably accurate, and light on system resources. As such, the design goals for OpenNTPD are: security, ease of use, and performance. [8]
