between the source of a packet and its destination.
o transmit data.
erver
ervers 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 (SUBNETwork 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.
SysLog Server
A SysLog server monitors incoming Syslog messages and decodes the messages for
logging purposes.
TCP
(Transmission Control Protocol) is the transport protocol in TCP/IP that ensures
messages over the network are transmitted accurately and completely.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol) is the main Internet
communications protocol. The TCP part ensures that data is completely sent and
received at the other end. Another part of the TCP/IP protocol set is UDP, which is
used to send data when accuracy and guaranteed packet delivery are not as important
(for example, in real-time video and audio transmission). The IP component of
TCP/IP provides data routability, meaning that data packets contain the destination
station and network addresses, enabling TCP/IP messages to be sent to multiple
networks within the LAN or in the WAN.
UDP
(User Datagram Protocol) is a protocol within TCP/IP that is used to transport
information when accurate delivery isn't necessary (for example, real-time video and
audio where packets can be dumped as there is no time for retransmitting the data).
Virtual Servers
Virtual servers are client servers (such as Web servers) that share resources with other
virtual servers (i.e., it is not a dedicated server).
RTS
RTS (Request To Send) is a signal sent from the transmitting station to the receiving
station requesting permission t
