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).
WAN
WAN (Wide Area Network) is a communications network that covers a wide
geographic area such as a country (contrasted with a LAN, which covers a small
area such as a company building).
