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 computers that store programs and data. The programs and data
are shared by client computers (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.
SNMP
SNMP (Simple Network Management Protocol) is a widely used network monitoring and control protocol.
SNMP hardware or software components transmit network device activity data to the workstation used to
oversee the network.
SSID
SSID (Service Set Identifier) is the name designated for a LAN. It serves as a simple security measure
used in Wireless LANs (WLANs). The SSID is attached to packets sent over WLANs. This identifier acts
as a password when a wireless device attempts communication on the WLAN. Because an SSID
distinguishes WLANS from each other, routers and wireless devices trying to connect to a WLAN must
use the same SSID.
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 System log 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
suite. TCP ensures that data is completely sent and received at the other end. 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 a high level application
protocol that uses 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 since
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).
