Internet primary and secondary servers synchronize to Coordinated Universal Time
(UTC).
Packet
A packet is a portion of data that is transmitted in network communications. Packets are
also sometimes called frames and datagrams. Packets contain not only data, but also the
destination IP address.
Ping
Ping (Packet INternet Groper) is a utility used to find out if a particular IP address is
present online, and is usually used by networks for debugging.
Port
Ports are the communications pathways in and out of computers and network devices
(routers and switches). Most PCs have serial and parallel ports, which are external
sockets for connecting devices such as printers, modems, and mice. All network adapters
use ports to connect to the LAN. Ports are typically numbered.
PPPoE
PPPoE (Point-to-Point Protocol Over Ethernet) is used for running PPP protocol
(normally used for dial-up Internet connections) over an Ethernet.
PPTP
Point-to-Point Tunneling Protocol uses TCP to deal data for tunnel maintenance, and uses
PPP for sum up the information carried within the tunnel. The data carried within the
tunnel can be compressed or encrypted. The encryption method used is RSA RC4. PPTP
can operate when the protocol is supported only on the client and the server located on
the other end that the client is corresponds with. No support is essential from any of the
routers or servers within the network the two PCs are connecting across.
Protocol
A protocol is a rule that governs the communication of data.
RIP
RIP (Routing Information Protocol) is a routing protocol that is integrated in the TCP/IP
protocol. RIP finds a route that is based on the smallest number of hops between the
source of a packet and its destination.

RTS
RTS (Request To Send) is a signal sent from the transmitting station to the receiving
station requesting permission to transmit data.
Server
Servers are typically powerful and fast machines that store programs and data. The
programs and data are shared by client machines (workstations) on the network.
SMTP
SMTP (Simple Mail Transfer Protocol) is the standard Internet e-mail protocol. SMTP is
a TCP/IP protocol defining message format and includes a message transfer agent that
stores and forwards mail.
Subnet Mask
Subnet Masks are used by IP protocol to direct messages into a specified network
segment (i.e., subnet). A subnet mask is stored in the client machine, server or router and
is compared with an incoming IP address to determine whether to accept or reject the
packet.
