equipment and links are tied together by network access points(NAPs), so that, for example, data can begin its journey on a Verizon link and then cross over to a Sprint link, if necessary, to reach its destination
allows you to use the Internet as you are on the go, such as using a cell phone to collect your email while you are traveling by train
(NAT) is the process your router usesto keep track of packets and their corresponding private or public IP addresses
Backbone links and routers are maintained by network service providers(NSPs), such as AT&T, Cogent Communications, Hurricane Electric, Sprint, and Verizon

Port probe
(or port scan) is the use of automated software to locate computers that have open ports and are vulnerable to unauthorized access
refers to data that never reaches its destination or gets discarded because it arrives too late to be of any use. Packet loss of less than 2% is required for acceptable VoIP
allows you to easily move your access device, as in the case of vehicle mounted satellite dishes that can be deployed when the vehicle is parked
(Packet Internet Groper), which sends a signal to a specific Internet address and waits for a reply
is a non‑routable IP address that can be used within a LAN, but not for internet data transport

Protocol suite
is one that can be accessed by packets on the Internet
allows people to exchange short messages while they are online
device that modulates the data signals from a computer into a frequency band that can be carried to the satellite dish, where it is converted to another frequency
is a combination of protocols that work together. TCP(Transmission Control Protocol) breaks a message or file into packets
is a means of distributing always on, high speed asymmetric Internet access by broadcasting signals to and from a personal satellite dish

Static IP address
refers to a model in which consumers access appli‑cations from a cloud provider over the Internet, usually by using a browser
>(Transmission Control Protocol) breaks a message or file into packets
As a general rule, computers on the Internet that act as servers use static IP addresses.
Some cell phones, such as Droids and iPhones, can act as a WiFi hotspot by becoming
the router for a wireless network
Instant messaging, chat, and VoIP are forms of synchronous communications; the people communicating have to be online at the same time and the conversation happens in real time

records a packet’s path in addition to its round trip speed
is the rate of data that is uploaded from your computer to the Internet
is a short message of 140 characters or less that is posted
Sales representatives and telecommuters often access corporate networks from home or
from a customer’s office by using a secured con‑nection called a virtual private
network(VPN)
usually referred to simply as a modem—converts the signals from your computer into
audible analog signals that can travel over telephone lines
