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 realtime 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.
TELNET
Telnet is a terminal emulation protocol commonly used on the Internet and TCP- or IP-based networks.
Telnet is used for connecting to remote devices and running programs. Telnet is an integral component of
the TCP/IP communications protocol.
UDP
(User Datagram Protocol) is a protocol within TCP/IP that is used to transport information when accurate
delivery isn't necessary (for example, realtime 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).
WEP
WEP (Wired Equivalent Privacy) is the de facto security protocol for wireless LANs, providing the
"equivalent" security available in hardwired networks.
WIRELESS LAN
Wireless LANs (WLANs) are local area networks that use wireless communications for transmitting data.
Transmissions are usually in the 2.4 GHz band. WLAN devices do not need to be lined up for
communications like infrared devices. WLAN devices use access points which are connected to the
wired LAN and provide connectivity to the LAN. The radio frequency of WLAN devices is strong enough
to be transmitted through non-metal walls and objects, and can cover an area up to a thousand feet.
Laptops and notebooks use wireless LAN PCMCIA cards while PCs use plug-in cards to access the
WLAN.
