Short Message Service (SMS)

A technology that enables the sending and receiving of messages between mobile devices. The

data that can be held by an SMS message is very limited. One SMS message can contain at most

140 bytes (1120 bits) of data, or up to 160 characters if 7-bit character encoding is used, and up

to 70 characters if 16-bit Unicode UCS2 character encoding is used.

Simple Mail Transfer Protocol (SMTP)

A TCP/IP protocol used in sending and receiving e-mail. Since it is limited in its ability to queue

messages at the receiving end, it is usually used with one of two other protocols, POP3 or IMAP,

that let the user save messages in a server mailbox and download them periodically from the

server. SMTP usually is implemented to operate over Internet port 25. An alternative to SMTP

that is widely used in Europe is X.400. Many mail servers now support Extended Simple Mail

Transfer Protocol (ESMTP), which allows multimedia files to be delivered as e-mail.

Simple Network Management Protocol (SNMP)

A protocol for managing and monitoring network devices. The SNMP architecture enables a

network administrator to manage nodes--servers, workstations, routers, switches, hubs, etc.--on

an IP network; manage network performance, find and solve network problems, and plan for

network growth.

static IP address assignment

The process of assigning a specific IP address to a device. Contrast with assigning a device

through Dynamic Host Configuration Protocol (DHCP), or Automatic Private IP Addressing

(APIPA or Auto-IP).
