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 (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 AP 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).
